Executive Intelligence Synthesis

UK SAF fuel suppliers face three simultaneous obligations by 2030: a 10% total SAF blending requirement (~1.5 billion litres annually), a HEFA cap reducing to 74.74% of the main obligation, and a mandatory Power-to-Liquid sub-obligation of 0.5%. The buy-out ceiling stands at £4.66/litre (main) and £4.93/litre (PtL). The UK government launched a formal call for evidence in June 2026 specifically investigating whether sufficient non-HEFA supply exists to meet the mandate — confirming that compliance in 2028–2030 is a live supply-development problem, not a certificate-purchasing exercise.


The five signals below capture the commercial decisions the UK SAF Mandate forces on every obligated supplier. Each follows the FINDING / SO WHAT / NOW WHAT framework — a data-backed fact, its direct implication for decision-making, and the specific action it implies. Read them in sequence: they define the structure of the compliance and procurement problem from 2026 to 2030.


Executive Signal 1: The Obligation Is Already Operating — and Climbing

  • FINDING: The UK SAF Mandate entered force on 1 January 2025, the main obligation reached 3.6% in 2026, and it rises to 5.2% in 2027, 6.6% in 2028, 8.2% in 2029, and 9.5% in 2030 — with a separate Power-to-Liquid sub-obligation adding a further 0.5% from 2030 for a total of 10%.

  • SO WHAT: A supplier treating 2030 compliance as a future planning exercise is already behind — each year's obligation requires certificates, physical supply, or buy-out payments, and the window for securing multi-year non-HEFA supply contracts narrows with every deferral.

  • NOW WHAT: Map your organisation's precise obligation in litres for each year from 2026 to 2030 based on your total obligated fuel volume, and establish which compliance route covers each year's shortfall.


Executive Signal 2: HEFA's Role Is Being Deliberately Reduced

  • FINDING: The HEFA cap stands at 100% of the main obligation in 2025 and 2026, falls to 92.31% in 2027, 87.88% in 2028, 80.49% in 2029, and 74.74% in 2030 — equivalent to approximately 71% of total UK SAF demand when the PtL obligation is included.

  • SO WHAT: The supply strategy that satisfies compliance in 2026 — maximum HEFA procurement — fails structurally from 2027 onwards, requiring an increasing volume of non-HEFA SAF that the domestic project pipeline cannot yet guarantee at the required scale.

  • NOW WHAT: Audit every current HEFA supply contract against the cap trajectory and identify the exact non-HEFA volume that must be contracted by technology pathway for each year from 2027 to 2030.


Executive Signal 3: PtL Is Mandatory From 2028 — and Nearly Four Times More Expensive Than HEFA

  • FINDING: The Power-to-Liquid sub-obligation begins at 0.2% of obligated fuel in 2028, rising to 0.5% in 2030 and 3.5% by 2040, with a modelled 2030 median production cost of £4,425/tonne — 3.76 times the £1,177/tonne median cost of HEFA.

  • SO WHAT: PtL is not an optional technology premium — it becomes a legal compliance requirement in 2028, and its production cost at that start date makes it the most commercially demanding procurement challenge in the entire mandate.

  • NOW WHAT: Evaluate whether any UK-based PtL projects — or international equivalents with UK-eligible certification — can be contracted before 2028, and model the PtL buy-out cost (£4.93/litre) as a planning ceiling against which physical procurement options are assessed.


Executive Signal 4: The UK Government Does Not Yet Have High Confidence in Non-HEFA Supply

  • FINDING: On 16 June 2026, the UK Department for Transport launched a formal call for evidence specifically examining future non-HEFA SAF availability, the HEFA cap, the PtL obligation and changes in aviation fuel management — while confirming that overall mandate targets will be maintained.

  • SO WHAT: When a government investigates whether its own policy target can be physically met, the commercial implication for an obligated supplier is direct: supply scarcity is no longer a theoretical risk, but a live operational and procurement concern with a policy dimension that remains unresolved.

  • NOW WHAT: Monitor the outcomes of the June 2026 evidence call and the final 2025 SAF Mandate statistics (due November 2026) as the two most important near-term signals for calibrating your 2027 and 2028 procurement positions.


Executive Signal 5: The Buy-Out Price Sets the Ceiling — and Must Drive Every Procurement Decision

  • FINDING: The buy-out price is £4.66/litre for the main obligation and £4.93/litre for the PtL obligation, with civil penalties reaching the lesser of £100,000 or 10% of turnover from covered fuels for non-compliance beyond the buy-out mechanism.

  • SO WHAT: The buy-out price establishes the maximum rational value of any SAF certificate, physical SAF procurement contract, or logistics premium — any cost stack exceeding the buy-out level should trigger a structured compliance cost review, not automatic payment.

  • NOW WHAT: Calculate total buy-out exposure at each obligation level from 2026 to 2030 as a financial planning ceiling, and use it to evaluate whether physical procurement, certificate trading, or partial buy-out is the optimal route for each year given current market conditions.


Macro Context & Strategic Drivers

The UK SAF Mandate requires qualifying fuel suppliers to blend increasing proportions of Sustainable Aviation Fuel into UK aviation fuel each year. The main obligation trajectory is 3.6% in 2026, 5.2% in 2027, 6.6% in 2028, 8.2% in 2029, and 9.5% in 2030. A separate Power-to-Liquid sub-obligation of 0.2% begins in 2028, rising to 0.5% in 2030. Combined, the total obligation reaches 10% of UK aviation fuel supply by 2030.

Why the UK Mandate Is Architecturally Distinct

  • FINDING: The UK SAF Mandate places the compliance obligation on qualifying fuel suppliers — companies supplying 15.9 TJ or more of relevant aviation turbine fuel — rather than on airlines, airports, or aviation operators.

  • SO WHAT: This supplier-side architecture concentrates commercial risk at the wholesale and refinery-gate level, meaning jet-fuel distributors and major fuel companies absorb the full financial and procurement exposure of non-compliance, irrespective of whether airlines pass costs upstream.

  • NOW WHAT: Confirm whether your organisation's total obligated fuel volume exceeds the 15.9 TJ threshold and identify all supply streams that qualify as obligated aviation turbine fuel under the current DfT definition.


The supplier-side design separates the UK mandate sharply from Brazil's ProBioQAV programme, which imposes emissions-reduction obligations on aviation operators, and from Singapore's centralised levy model, where a government body procures and allocates SAF through a pooled mechanism. The UK structure ensures that the commercial SAF premium — the cost difference between SAF and conventional jet fuel — falls first on the fuel supply chain, not on the airline. The pass-through of that cost to airlines and ultimately passengers is a commercial negotiation, not a regulatory certainty.


As Mike Kane MP, Minister for Aviation, Maritime and Security at the UK Department for Transport, stated in May 2025:

"SAF will play an important part in reducing emissions from aviation and is already being used in aircraft today."

The minister simultaneously identified uncertainty around future SAF revenues as a key barrier to investment — which is precisely why the Revenue Certainty Mechanism (RCM) is being built alongside the mandate. The two policies together create a dual financial exposure for fuel suppliers: direct compliance costs from the mandate, and a variable RCM levy on fossil aviation fuel market share. Neither can be assessed in isolation.

The table below provides the full confirmed obligation schedule from the DfT SAF Mandate Compliance Guidance, expressed as a percentage of total UK aviation fuel supply. Approximate annual volumes are GFJ estimates based on the DfT-confirmed 2030 figure of approximately 1.5 billion litres.

Global Policy Comparator: Where the UK Sits

Understanding the UK's position relative to other SAF policy regimes is commercially essential for any supplier with international supply chains.

As Apostolos Tzitzikostas, Commissioner for Sustainable Transport and Tourism at the European Commission, stated on 28 February 2025:

"ReFuelEU Aviation sets European air transport on a solid path to decarbonisation."

The EU mandate advancing at 6% by 2030 with a 1.2% synthetic sub-target simultaneously expands the pool of buyers competing for the same global SAF feedstock supply.

The IEA projects global SAF supply at approximately 9 billion litres by 2030 — equivalent to only ~2% of global aviation fuel demand. The UK's 10% target is approximately five times more demanding than that projected global average, confirming that the UK cannot assume global supply growth automatically solves its domestic obligation.


Compliance Mechanics: The Three Routes to Meeting Your Obligation

UK fuel suppliers have three legally recognised compliance routes.

  • Route 1 — physical SAF procurement — generates SAF Certificates (SAFCs) proportional to GHG savings achieved.

  • Route 2 — certificate trading — allows purchase of SAFCs from other obligated suppliers.

  • Route 3 — buy-out — pays £4.66/litre for the main obligation or £4.93/litre for PtL. Physical supply is not required: all three routes are legally valid.


The buy-out rate is set at a level that makes it commercially punishing at scale, and it does not eliminate RCM levy exposure.


Route 1: Physical SAF Procurement and SAFC Generation

  • FINDING: SAF Certificates (SAFCs) are issued in proportion to the greenhouse gas (GHG) savings delivered by the fuel relative to fossil kerosene — meaning a higher-performing SAF feedstock generates more certificates per litre than a lower-performing one against the same physical volume supplied.

  • SO WHAT: Physical SAF procurement is not purely a volume decision — feedstock carbon intensity directly determines the certificate yield, which means a supplier optimising purely for lowest SAF procurement cost per litre may be generating a sub-optimal number of certificates per £ spent.

  • NOW WHAT: Evaluate prospective SAF supply contracts on a cost-per-certificate basis, not only on a cost-per-litre basis, and verify the GHG savings pathway and sustainability certification for every supplier before contracting.


The chain-of-custody requirements and sustainability certification mean that international SAF procurement — whether from North America, Europe, or Asia — requires pre-contract verification of the specific certification standard (ISCC CORSIA, RSB, or equivalent) held by the producing facility. Physical supply also carries the most direct market risk in a tight supply environment: if eligible SAF is physically unavailable from contracted sources, the supplier must either locate alternative physical supply at short notice, enter the certificate market, or resort to buy-out.


For analysis of how feedstock constraints are shaping SAF procurement costs globally, see GFJ's SAF Feedstock Reality Check 2026: https://www.greenfueljournal.com/post/saf-feedstock-reality-check-2026


Route 2: Certificate Trading

  • FINDING: The SAFC market allows obligated suppliers to acquire compliance from other participants who have generated certificates through physical SAF supply, providing a compliance pathway without requiring direct access to physical SAF volumes.

  • SO WHAT: Certificate trading provides tactical flexibility, but at a cost determined by market supply and demand — and the SAFC market is new, unproven, and price-untested in any supply-constrained environment.

  • NOW WHAT: Engage with the SAFC market as an intelligence-gathering exercise now, before scarcity pricing sets in — understanding current certificate availability and implied pricing against the buy-out ceiling informs whether certificate procurement is viable for 2027 or whether physical SAF contracts are the more commercially predictable route.


Certificate quality is not uniform — it reflects the GHG savings of the underlying SAF pathway and feedstock. A certificate from a highly efficient advanced-pathway SAF carries more GHG-reduction value than one from a lower-efficiency HEFA batch, even if both count toward the same volume of obligation discharge. The rational ceiling for any certificate price is the buy-out rate: no economically rational supplier will pay more for a certificate than the cost of buying out that portion of its obligation. This ceiling makes the buy-out mechanism a de facto price cap on the certificate market — and a critical reference point in every certificate procurement negotiation.


For analysis of SAF cost premium dynamics, see GFJ's SAF Price Premium: Part I: https://www.greenfueljournal.com/post/the-saf-price-premium-part-i


Route 3: Buy-Out

  • FINDING: The buy-out price is £4.66/litre for the main obligation and £4.93/litre for the PtL sub-obligation, with civil penalty exposure for non-compliance reaching the lesser of £100,000 or 10% of turnover from covered fuels in relevant circumstances.

  • SO WHAT: Buy-out is the government's designed compliance safety valve and functions as an effective cost ceiling on the mandate — but at £4.66/litre, systematic buy-out at scale constitutes a very significant annual cash outflow that exceeds the delivered cost of physical HEFA SAF under most current market scenarios.

  • NOW WHAT: Calculate your maximum buy-out exposure at each obligation level from 2026 to 2030, and use this as the ceiling against which all physical SAF and certificate procurement costs are evaluated — not as a fallback to be costed only when other routes fail.


Buy-out should not be interpreted as an easy option. Given the scale of UK aviation fuel demand and the 9.5% main obligation at 2030, systematic buy-out implies a cost exposure in the hundreds of millions of pounds before the PtL component — well above what targeted physical SAF procurement would cost under most plausible market scenarios. Most obligated suppliers will use buy-out tactically, to cover specific volume shortfalls in years when physical supply or certificate availability falls short, rather than as a primary compliance strategy.

The strategic framework emerging from this matrix: physical SAF procurement offers the highest certainty and the best cost control under a well-managed multi-year supply strategy. Certificate trading provides tactical flexibility but exposes the buyer to market pricing in an unproven and potentially volatile market. Buy-out protects against worst-case scenarios but is too costly at scale to serve as a primary compliance strategy beyond isolated volume gaps. Most obligated suppliers will need all three routes in their compliance toolkit — the strategic question is which mix, in which years, at what cost ceiling.

The HEFA Problem: Managing Your Supply Portfolio Through the Cap

HEFA-derived SAF can satisfy 100% of the main obligation in 2025 and 2026. The cap then reduces annually: 92.31% in 2027, 87.88% in 2028, 80.49% in 2029, and 74.74% in 2030 — approximately 71% of total UK SAF demand when the PtL sub-obligation is included. Suppliers must source a growing proportion of compliance from non-HEFA pathways, while simultaneously meeting the Power-to-Liquid obligation beginning in 2028.

How the HEFA Cap Works Year by Year 

  • FINDING: From 2027, the HEFA cap reduces the eligible contribution of HEFA-derived certificates in each compliance year — starting at 92.31% of the main obligation in 2027 and declining to 74.74% by 2030, meaning every successive year requires a larger absolute volume of non-HEFA SAF regardless of whether a supplier's total obligated fuel volume changes.

  • SO WHAT: A supplier who locks in a multi-year HEFA supply agreement covering 100% of their current obligation will carry a compliance gap that widens from 7.69 percentage points in 2027 to 25.26 percentage points of the main obligation in 2030, before the PtL sub-obligation is added.

  • NOW WHAT: Model the HEFA-to-non-HEFA transition in your supply portfolio on a year-by-year basis and identify the non-HEFA volume required in each year — this supply gap drives procurement strategy for the remainder of the decade.


The UK government launched its June 2026 call for evidence specifically because it wants to understand whether non-HEFA supply is actually available at the volumes the cap implies. The government's own evidence-gathering on this question is the clearest signal available that compliance in 2028–2030 is fundamentally a supply-development and procurement problem, not simply a certificate-purchasing exercise.


For context on how feedstock competition is shaping HEFA availability, see GFJ's SAF Feedstock Reality Check 2026: https://www.greenfueljournal.com/post/saf-feedstock-reality-check-2026


Quantifying the Non-HEFA Gap

  • FINDING: The four projects awarded support through the UK Advanced Fuels Fund — LanzaTech DRAGON (79 kt/y), Alfanar Energy's Lighthouse Green Fuels (86.6 kt/y), Fulcrum NorthPoint (83.7 kt/y), and Velocys Altalto (37.4 kt/y) — represent a combined stated capacity of approximately 286.7 kt/y, all of it non-HEFA.

  • SO WHAT: The UK government estimates 10% SAF by 2030 equates to approximately 1.5 billion litres annually (~1,200 kt at typical density) — meaning the four funded non-HEFA projects represent approximately 24% of the total 2030 requirement in stated capacity terms, none of it yet operating at scale.

  • NOW WHAT: Do not assume that the Advanced Fuels Fund project pipeline delivers the non-HEFA volume the mandate requires — according to Dentons' 2025/2026 SAF market analysis, 5.8 million tonnes of additional SAF capacity must reach Final Investment Decision during 2026–2027 to support mandated 2030 demand, confirming the funded domestic pipeline is a fraction of what the market needs.

The arithmetic is commercially significant. If a fuel supplier's total obligated volume were, say, 2 billion litres of aviation turbine fuel annually, then the 2030 main obligation of 9.5% implies approximately 190 million litres of SAF required. Of that, 74.74% — approximately 142 million litres — can come from HEFA. The remaining ~48 million litres, plus 0.5% PtL (~10 million litres), must come from non-HEFA pathways currently not commercially available at UK-accessible scale.


PtL: The Compliance Route No Supplier Can Ignore After 2028

  • FINDING: The UK government's final-stage cost-benefit analysis models a 2030 median production cost for PtL of £4,425/tonne, against a 2030 median HEFA cost of £1,177/tonne — a differential of 3.76 times, placing PtL as the most expensive commercially mandated SAF pathway by a substantial margin.

  • SO WHAT: The PtL obligation is not an optional premium route — it is a legal compliance requirement from 2028, and its production cost at that start date will significantly exceed anything the HEFA market currently prices, making the £4.93/litre buy-out rate the rational comparison point for any early-stage PtL contract evaluation.

  • NOW WHAT: Evaluate the Revenue Certainty Mechanism allocation timeline as the primary near-term policy event that could make PtL offtake commercially viable before 2028, and assess whether any UK-based or internationally certified PtL project could provide the 0.2% obligation volume at a cost below the PtL buy-out rate.

If the RCM can de-risk PtL project financing sufficiently to bring production costs below the £4.93/litre buy-out ceiling before 2028, the mandate becomes more commercially manageable. If not, the PtL buy-out becomes the default compliance mechanism for the sub-obligation — an outcome the government explicitly says it does not want, but which current supply signals make plausible.

Named Company Case Studies: What Actual UK SAF Supply Looks Like

The UK Department for Transport's Advanced Fuels Fund has supported four non-HEFA projects with a combined stated capacity of approximately 286.7 kt/y: LanzaTech DRAGON (79 kt/y, expected 2026), Alfanar Energy Lighthouse (86.6 kt/y, expected 2028), Fulcrum NorthPoint (83.7 kt/y), and Velocys Altalto (37.4 kt/y). Internationally, IndianOil's Panipat facility received ISCC CORSIA certification in August 2025, establishing India as a certified potential import source within the HEFA cap.


LanzaTech UK: DRAGON at Port Talbot — The Non-HEFA Technology Signal

  • FINDING: LanzaTech's DRAGON project in Port Talbot, Wales, converts steel-mill off-gases into ethanol via fermentation, then into ATJ-SAF, with a stated capacity of 79 kt/y, government support of £24.96 million from the Advanced Fuels Fund, and an expected operational date of 2026.

  • SO WHAT: DRAGON represents precisely the type of industrial-waste-to-SAF pathway the UK mandate needs to fill the non-HEFA gap from 2027, but as a first-of-kind commercial deployment of the gas fermentation-to-ATJ process at this scale, stated capacity and operational capacity are not equivalent — delivery risk is real and must be factored into any supply planning that relies on DRAGON volumes.

  • NOW WHAT: If evaluating DRAGON as a potential supply source, engage directly with LanzaTech on commercial terms and operational commissioning status before treating its 79 kt/y capacity as a confirmed volume in your compliance planning.


DRAGON's feedstock — waste industrial gases from steel manufacturing — illustrates a supply-chain design principle the UK mandate structurally requires: eligible feedstocks that are not in direct competition with food, feed, or the waste-oil supply chains that HEFA currently relies on. The steel sector's off-gas volumes are determined by steel production rates, not by agricultural commodity markets, giving DRAGON a feedstock base that is structurally different from lipid-dependent HEFA — relevant for long-term supply security, even if it introduces a different set of industrial and process risks.


Alfanar Energy: Lighthouse Green Fuels at Teesside — The 2028 Timing Tension

  • FINDING: Alfanar Energy's Lighthouse Green Fuels project at Teesside uses waste gasification and Fischer-Tropsch synthesis to produce SAF at a stated capacity of 86.6 kt/y, with £11.001 million in government support and an expected operational date of 2028.

  • SO WHAT: The 2028 start date means Lighthouse arrives in the same year the PtL obligation begins and the HEFA cap enters its most significant two-year tightening phase — compressing the demonstration window for both Alfanar's technology and its commercial integration into UK SAF supply chains simultaneously.

  • NOW WHAT: Include Alfanar's Teesside location advantage — proximity to North Sea-adjacent fuel supply infrastructure — in any logistics and aggregation analysis, but plan conservatively: a 2028 first-year operational project should not be treated as a reliable baseload source in your 2028 compliance model.


The Teesside location provides a meaningful logistics advantage for fuel suppliers operating within the North Sea fuel distribution network. Lighthouse's proximity to North East England's industrial port infrastructure reduces the transport cost variable in the total landed cost of SAF — a factor underanalysed in most public SAF economics modelling. That advantage does not change the fundamental challenge Alfanar Energy shares with LanzaTech: stated capacity is not operational capacity, and the compliance planner must account for a ramp-up period before any new-build facility reaches nameplate throughput.


IndianOil: Panipat and Paradip — The International Supply Case

  • FINDING: IndianOil's Panipat refinery received ISCC CORSIA certification for SAF production in August 2025, making it India's first internationally certified SAF facility; IndianOil's 2025–26 annual report also identifies a planned 100 kt/y HEFA SAF facility at Paradip.

  • SO WHAT: IndianOil's ISCC CORSIA certification establishes that Indian-produced SAF can meet the sustainability verification requirements for regulated markets including the UK and EU, meaning UK fuel suppliers have a traceable, certified HEFA supply option from a non-European source within the HEFA cap's remaining permitted volume.

  • NOW WHAT: Assess IndianOil's Panipat and planned Paradip capacity as a potential international HEFA supply source, and verify the chain-of-custody and UK-specific eligibility requirements against your SAF procurement team's compliance framework before initiating commercial discussions.


India's civil aviation minister, Ram Mohan Naidu, stated on 29 July 2026:

"India is committed to building a robust and globally competitive Sustainable Aviation Fuel ecosystem."

The ministerial framing positions SAF as a strategic export opportunity for Indian producers. India's indicative blending targets for international flights (1% in 2027, 2% in 2028, 5% in 2030) are CORSIA-linked rather than driven by a domestic mandatory-blending regime comparable to the UK's — meaning Indian producers like IndianOil face significantly less domestic demand pressure than EU or US counterparts, creating a structural export supply window that UK buyers should evaluate now.


For context on India's clean fuel export architecture, see GFJ's Green Ammonia Exports 2027: https://www.greenfueljournal.com/post/green-ammonia-exports-2027


Global SAF Supply: Can UK Suppliers Source Internationally?

The IEA projects global SAF supply at approximately 9 billion litres in 2030 — equivalent to roughly 2% of global aviation fuel demand. The UK's 10% mandate target implies approximately 1.5 billion litres from a single country, equivalent to approximately 17% of the projected global total. The EU's concurrent 6% mandate adds a further substantial competing demand. The constraint is not global production volume alone — it is feedstock access, certification, logistics, and international competition for the same eligible supply.



The Global Supply Equation

  • FINDING: The IEA's Renewables 2025 forecast estimates global SAF consumption at approximately 1 billion litres in 2024, rising to approximately 9 billion litres in 2030 — representing only about 2% of global aviation fuel demand at that point.

  • SO WHAT: The UK's 10% mandate is approximately five times more demanding than the IEA's projected global average SAF share in 2030, meaning the UK cannot assume that a globally growing SAF market will automatically provide the volumes it needs — UK demand represents a disproportionate claim on a still-thin global supply pool.

  • NOW WHAT: Do not base UK compliance planning on global supply growth forecasts — base it on specific, certified, contractable supply volumes from identified producers with confirmed UK eligibility, logistics paths, and sustainability certification.


US Capacity: Large Pipeline, Different Architecture

  • FINDING: The US Department of Energy's SAF Grand Challenge progress report identifies announced projects representing more than 3 billion gallons/year of potential 2030 capacity with approximately $44 billion in announced funding — but the US production incentive architecture (the 45Z Clean Fuel Production Credit, valued at up to $1.75/gallon for SAF, and the Renewable Fuel Standard) is oriented toward domestic compliance and US-market production, not UK export supply.

  • SO WHAT: Large US SAF project capacity does not translate automatically into accessible UK supply — feedstock origin, sustainability certification pathway (ISCC CORSIA or RSB, not USDA or RFS-only), and UK eligibility must be confirmed separately for any US-origin SAF import, and domestic US demand will absorb much of the projected US output.

  • NOW WHAT: Screen any US-origin SAF supply against UK sustainability and chain-of-custody requirements before treating US capacity announcements as a reliable element of UK compliance planning.


EU Competition: Shared Feedstocks, Adjacent Mandate

  • FINDING: The European Commission reported in October 2025 that 25 fuel suppliers supplied SAF to 33 EU airports across 12 Member States in 2024 — a concentrated market now required to scale to 6% of total EU aviation fuel by 2030, with a 1.2% synthetic sub-target.

  • SO WHAT: The EU and UK compete directly for the same European waste-oil, agricultural residue, and advanced-feedstock supply chains — meaning every additional percentage point of EU compliance absorbs feedstock capacity that UK suppliers may have assumed was available to them.

  • NOW WHAT: Map feedstock origin in your current and prospective SAF supply contracts and identify which feedstock sources are simultaneously targeted by EU mandate compliance — feedstock competition between EU and UK buyers is the most material supply-side risk for HEFA procurement in 2027–2029.


India: Emerging Supplier with a Growing Certification Base

IndianOil's ISCC CORSIA certification for Panipat, obtained in August 2025, and its planned 100 kt/y HEFA facility at Paradip represent the most concrete evidence of Indian supply with internationally recognised credentials. India's SAF blending targets for international flights are CORSIA-linked rather than driven by a domestic mandatory-blending regime, meaning IndianOil and other Indian producers face significantly lower domestic demand pressure than their EU or US counterparts in the same period. This creates a structural window for UK import sourcing from India — but only within the HEFA cap's permitted volume, and only through supply chains that can demonstrate UK-eligible sustainability certification for the feedstock origin and production process.


Certification and Logistics as Practical Supply Barriers

  • FINDING: UK SAF eligibility requires sustainability certification to standards recognised by the RTFO/SAF Mandate technical framework — including ISCC CORSIA and RSB — with full chain-of-custody documentation that traces the feedstock from origin through processing to delivery.

  • SO WHAT: A SAF producer with commercial-scale capacity but no UK-recognised sustainability certification cannot supply into the UK compliance market regardless of the physical SAF's actual carbon performance — certification is a binary eligibility gate, not a scoring variable.

  • NOW WHAT: Before initiating any international SAF supply discussion, verify the specific certification standards held by the producing facility, confirm that the feedstock origin qualifies under UK eligibility rules, and add the logistics and certification cost to the landed-cost model against the buy-out ceiling.

Friction, Risk & Systemic Bottlenecks

Five material risks face UK fuel suppliers:

  • (1) non-HEFA supply inadequacy — the UK government's own June 2026 evidence call signals this is unresolved;

  • (2) feedstock competition between UK, EU, US, and marine biofuel buyers;

  • (3) certificate market price volatility in a market where pricing dynamics are untested;

  • (4) tankering — compliance geography distortions the government is actively investigating; and

  • (5) the RCM levy, which creates a parallel financial exposure that does not disappear with SAF compliance.


For analysis of how SAF cost dynamics are likely to evolve, see GFJ's SAF Price Premium: Part II: https://www.greenfueljournal.com/post/the-saf-price-premium-part-ii


The Non-HEFA Supply Gap: The Mandate's Unresolved Strategic Problem

  •  FINDING: According to Dentons' 2025/2026 SAF market analysis, 5.8 million tonnes of additional SAF capacity must reach Final Investment Decision during 2026–2027 to support mandated 2030 demand — against which the four Advanced Fuels Fund project winners represent 286.7 kt/y of stated, not operational, capacity.

  • SO WHAT: The domestic non-HEFA pipeline is a fraction of the scale required, and the UK government's own June 2026 evidence call confirms that supply adequacy for 2028–2030 is a genuinely unresolved question — not a gap the government has a confident plan to fill.

  • NOW WHAT: Build Scenario B (supply gap) planning into your compliance model now — assume non-HEFA supply falls short of the mandated trajectory and establish what that implies for your certificate market exposure and buy-out cost in 2028, 2029, and 2030.


The government's June 2026 call for evidence is not a routine policy review — it is the government investigating whether its own mandate can be physically fulfilled. When a regulator investigates supply adequacy while simultaneously confirming that targets will be maintained, the message to obligated suppliers is direct: the cost of under-preparation falls on the supplier, not the regulator.


Feedstock Competition: Who Else Is Buying What UK Suppliers Need

  • FINDING: The IEA identifies limited availability of waste oils, fats, and residues — the primary HEFA feedstocks — as a major constraint on SAF supply, with used cooking oil, tallow, and other lipid feedstocks simultaneously targeted by UK SAF, EU SAF, US renewable diesel, marine biofuels, and road biofuel producers.

  • SO WHAT: The feedstock competition problem means that even a supplier with the financial capacity to pay for large HEFA SAF volumes may face a physical supply limit that money alone cannot solve — the eligible feedstock pool is not price-elastic at any realistic premium over conventional alternatives.

  • NOW WHAT: Diversify SAF supply away from used cooking oil as the sole feedstock basis, and examine which advanced-pathway feedstocks (agricultural residues, municipal solid waste, industrial off-gases) offer supply chains less exposed to cross-sector competition.



Certificate Market Risk: Price Volatility in an Unproven Market

  • FINDING: The SAFC market is new — certificate prices are untested under supply-constrained conditions, and will be determined by the intersection of physical SAF volumes, pathway mix, GHG savings per litre, demand from obligated suppliers approaching compliance deadlines, and the proximity of the buy-out ceiling.

  • SO WHAT: A supplier relying primarily on certificate trading for 2028 or 2029 compliance is exposed to a market that has never been stress-tested in a supply-short environment — if physical SAF availability falls short of system-level demand, certificate prices could approach the buy-out ceiling quickly, eliminating the cost advantage that makes certificate trading rational.

  • NOW WHAT: Treat the buy-out price as the maximum rational ceiling for any certificate purchase — and build in procurement timing that avoids year-end deadline pressure, when certificate scarcity will be most acute and pricing most adverse.


Tankering: The Compliance Arbitrage Risk

  • FINDING: The UK government's June 2026 call for evidence specifically requested data on how aviation fuel management practices — particularly tankering — may change following implementation of the SAF Mandate.

  • SO WHAT: If SAF is significantly cheaper or more accessible at certain fuelling locations, airlines have a rational incentive to manage where SAF is physically uplifted versus where it is legally required — creating compliance-geography distortions that could alter the effective demand profile facing UK-based fuel suppliers.

  • NOW WHAT: Monitor the outcomes of the June 2026 tankering evidence call as a potential source of mandate design modification — if the government determines that tankering is materially distorting compliance, regulatory intervention affecting supplier geography and certificate allocation is a plausible policy response.


The tankering issue remains open precisely because the mandate is new and real-world compliance behaviour has not yet been observed at scale. The government is not treating tankering as a resolved question — and suppliers should not either.


Revenue Certainty Mechanism: The Levy Exposure Fuel Suppliers Often Overlook

  • FINDING: The RCM will be funded through a variable levy on aviation fuel suppliers calculated on their market share of fossil-based aviation turbine fuel — meaning as a supplier's fossil jet-fuel volume declines (partly as SAF displaces it), the levy base and levy amount change in a dynamic that requires separate modelling from the direct SAF procurement cost.

  • SO WHAT: The RCM levy creates a parallel financial obligation that does not disappear when SAF compliance is achieved — it continues to apply on the fossil fuel component of a supplier's total volume, and interacts with SAF procurement decisions in ways that require integrated financial modelling, not separate assessment.

  • NOW WHAT: Integrate the RCM levy calculation into your 2026–2030 SAF compliance cost model and assess the combined financial exposure — mandate compliance cost plus levy exposure — as a single economic planning problem, not two separate line items.


Capital & Investment Implications

Compliance cost depends on route and year. The cheapest current pathway, HEFA, carries a 2030 median production cost of £1,177/tonne, but is capped from 2027. Non-HEFA pathways range from £2,627/tonne (ATJ) to £4,425/tonne (PtL). The buy-out ceiling stands at £4.66/litre (main) and £4.93/litre (PtL). The effective compliance cost rises structurally as the HEFA cap forces suppliers toward more expensive pathways. The RCM levy on fossil aviation fuel market share adds a further, parallel financial exposure.

The SAF Compliance Cost Stack

  • FINDING: HEFA is the cheapest compliant SAF pathway at a modelled 2030 median of £1,177/tonne, but the HEFA cap's reduction to 74.74% of the main obligation by 2030 means compliance requires pathways costing between 2.2× and 3.76× the HEFA baseline — with PtL's mandatory sub-obligation adding the most expensive tier as a legal requirement from 2028.

  • SO WHAT: The effective average cost of compliance per tonne of SAF procured rises structurally each year as the HEFA cap forces a larger proportion of procurement into higher-cost pathways — a supplier modelling 2030 compliance costs at 2026 HEFA prices will materially underestimate their financial exposure.

  • NOW WHAT: Build a blended compliance cost model that weights HEFA, non-HEFA, and PtL pathways at their respective cap and sub-obligation percentages for each year from 2026 to 2030, and update the model quarterly as market pricing evolves.


The structural cost stack, from base to ceiling, runs:

HEFA baseline (£1,177/t 2030 median) → non-HEFA premium (ATJ £2,627/t, HtL £2,972/t, BtL £3,384/t) → certification and chain-of-custody verification → logistics and aggregation costs → certificate market exposure → PtL sub-obligation (£4,425/t median) → buy-out ceiling (£4.66/litre main / £4.93/litre PtL) → RCM levy on fossil volumes. No single-pathway strategy covers the full obligation after 2026.

SAF Revenue Certainty Mechanism: Supplier Financial Exposure

The UK Department for Transport published the RCM contract allocation strategy on 13 July 2026, following the January 2026 consultation on indicative heads of terms, sustainability criteria, reference pricing, and strike pricing. The RCM is designed to provide revenue certainty for SAF producers — reducing the investment risk that has historically deterred project financing for non-HEFA facilities. It is funded through a levy on aviation fuel suppliers based on their market share of fossil-based aviation turbine fuel. The UK government has indicated its expectation that RCM legislation will be in place by the end of 2026, subject to parliamentary process, making the first allocation round a near-term commercial event with direct implications for which SAF producers receive government-backed revenue certainty — and therefore which supply agreements are most commercially durable.


Why 2026–27 Decisions Define 2030 Compliance Economics

Long-term SAF offtake agreements, advanced-project FID commitments, and certificate-market positioning all have multi-year lead times for non-HEFA pathways. Dentons' 2025/2026 SAF analysis identifies that investment decisions being made now — by producers and their financiers — will determine whether physical non-HEFA SAF is commercially available in the quantities the mandate requires. A fuel supplier that defers supply contract negotiations until 2028 will be competing for a constrained project pipeline that has already committed most of its output to suppliers who moved earlier.


Future Scenarios & Forecast: 2026–2030

If non-HEFA supply falls short of the mandate's requirements, the buy-out mechanism at £4.66/litre (main) and £4.93/litre (PtL) functions as the designed compliance fallback. Suppliers face escalating certificate prices approaching the buy-out ceiling, increasing buy-out cost exposure, and potential government policy intervention to adjust the HEFA cap trajectory or PtL timeline. The government has confirmed it will maintain overall mandate targets. Suppliers without a multi-pathway compliance strategy face the highest financial exposure in this scenario.


Infographic titled UK SAF mandate 2026-2030 showing three compliance scenarios, charts, icons, and November 2026 data release.

Scenario

Supply Conditions

SAFC Market

Buy-Out Use

Supplier Positioning

A: Aligned Delivery (Base)

UK non-HEFA projects (LanzaTech, Alfanar, Velocys, Fulcrum) operational on schedule. Certified international HEFA supplements within cap. PtL met through RCM-supported projects.

Certificate prices sustainable below buy-out ceiling.

Tactical — specific volume gaps only.

Early offtake with non-HEFA project winners. Certificate market as tactical complement. Buy-out budgeted as contingency.

B: Supply Gap (Risk)

Non-HEFA domestic projects face delays. HEFA available but capped, creating shortfall. PtL commercial volume not available at 2028 start.

Certificate prices tighten; market approaches buy-out ceiling, particularly for PtL certificates.

Systematic — covers the non-HEFA gap alongside maximum HEFA within cap.

Maximise HEFA within cap. Certificate trading as primary compliance for gap. Buy-out as planned backstop. Actively source certified international HEFA (India, US).

C: Structural Buy-Out (Stress)

PtL projects not commercially available by 2028. Non-HEFA pipeline significantly behind. Government maintains targets.

Certificate market distressed. PtL certificates extremely scarce or unavailable at sub-buy-out prices.

Structural for PtL sub-obligation. Partial for non-HEFA main obligation gap.

Buy-out exposure explicitly modelled for 2028–2029. Engage government on PtL obligation deferral. Monitor November 2026 mandate statistics. Maintain physical HEFA maximum.

 

Scenarios B and C are not fringe outcomes — the government's own evidence call confirms that the non-HEFA supply adequacy question remains open. The November 2026 final 2025 SAF Mandate statistics will be the first complete empirical dataset on UK mandate performance, providing the clearest available signal for recalibrating supply assumptions before the 2027 HEFA cap reduction takes effect.


Strategic Recommendations

Five actions for UK fuel suppliers:

  • 1) Map your precise obligation in litres for each year from 2026 to 2030.

  • (2) Audit HEFA supply contracts against the annual cap trajectory.

  • (3) Evaluate long-term non-HEFA offtake options from Advanced Fuels Fund project winners.

  • (4) Model the certificate market as a tactical complement, not a primary strategy.

  • (5) Quantify maximum buy-out exposure at each obligation level as a financial planning ceiling.

The November 2026 mandate statistics dataset and the RCM allocation outcome are the two most important near-term intelligence events for obligated suppliers.


For UK Fuel Suppliers

1. Map your precise obligation by year and volume. Calculate your exact compliance obligation in litres for each year from 2026 to 2030, based on your total obligated fuel volume and the confirmed annual percentages. Split the calculation into main obligation and PtL sub-obligation from 2028.


2. Audit current HEFA supply contracts against the cap trajectory. Identify the specific volume of HEFA SAF that exceeds the eligible percentage in each year from 2027 to 2030, and quantify the non-HEFA procurement gap those contracts leave uncovered.


3. Evaluate long-term non-HEFA offtake agreements with Advanced Fuels Fund project winners. LanzaTech DRAGON, Alfanar Energy Lighthouse, Fulcrum NorthPoint, and Velocys Altalto are the most credible UK-based non-HEFA supply sources — initiate commercial discussions with each to assess whether supply volumes, technology risk, and pricing align with your 2027–2030 compliance requirements.


4. Model the certificate market as a tactical complement, not the primary compliance vehicle. Certificate trading provides flexibility, but is exposed to pricing volatility in a supply-constrained market. Use physical SAF procurement as the primary strategy and the certificate market for specific volume gaps with defined buy-out ceiling discipline.


5. Quantify your maximum buy-out exposure in each of the three scenarios as a financial planning ceiling. This figure — buy-out price multiplied by the uncovered obligation volume in each year — is the worst-case compliance cost your financial planning must accommodate, not an outcome to be discovered at year-end.


For SAF Producers and Investors

1. Treat the RCM contract allocation strategy as the most important near-term policy event. The July 2026 contract allocation strategy sets the terms under which SAF producers will receive revenue certainty for UK-based production. Understanding the technology eligibility, volume allocation method, and strike-price framework is the prerequisite for any credible UK SAF project financing.


2. Invest in sustainability certification before seeking supply agreements. ISCC CORSIA or RSB certification is the binary eligibility gate for UK market access. Certification investment should precede commercial negotiation, not follow it.


3. Price project delivery risk explicitly in offtake negotiations. The delivery risk between 2026 and 2028 — when the mandate's most critical technology transition occurs — is the single greatest variable in whether an offtake agreement creates stable long-term economics. Suppliers will discount supply contracts that carry unreserved technology delivery risk.


For Policymakers

1. Publish the November 2026 mandate statistics with a clear policy communication on non-HEFA supply assessment. The first complete 2025 compliance dataset will be the most important empirical signal the market receives. Publishing it without a government assessment of its implications for 2027–2030 supply adequacy will extend the investment uncertainty the RCM is designed to reduce.


2. Ensure the tankering evidence call produces actionable findings before the 2028 PtL obligation takes effect. If tankering is distorting the compliance geography of the mandate, corrective action before 2028 is significantly less disruptive than mid-obligation regulatory intervention after the PtL sub-obligation is live.

 

For an obligated supplier entering 2027, the most consequential action is not sourcing the cheapest individual tonne of SAF — it is building a multi-pathway compliance portfolio that specifies the HEFA volume within the cap, the non-HEFA offtake under contract, the certificate strategy for any remaining gap, and the buy-out exposure as a financial planning ceiling. That portfolio, built from the verified supply infrastructure available today and updated against the November 2026 mandate statistics, is the only defensible position as the UK's most demanding compliance years approach.


Executive FAQ: UK SAF Mandate 2026–2030


What are the exact SAF blending percentages UK fuel suppliers must meet each year from 2026 to 2030?

The total obligation (main + PtL) is: 3.6% in 2026; 5.2% in 2027; 6.8% in 2028 (main 6.6% + PtL 0.2%); 8.4% in 2029 (main 8.2% + PtL 0.2%); and 10.0% in 2030 (main 9.5% + PtL 0.5%). These figures are expressed as percentages of total UK aviation fuel supply. Source: UK Department for Transport, SAF Mandate Compliance Guidance 2026.


How does the HEFA cap work under the UK SAF Mandate and what happens when it tightens?

The HEFA cap limits the proportion of the main obligation that can be met using HEFA-derived certificates. It stands at 100% in 2025 and 2026, then reduces to 92.31% in 2027, 87.88% in 2028, 80.49% in 2029, and 74.74% in 2030. For every percentage point the cap falls, a supplier must source an equivalent volume from non-HEFA pathways or deploy certificates from those pathways to maintain full compliance.


Can UK fuel suppliers pay the buy-out price instead of physically supplying SAF?

Yes. The buy-out mechanism is a legally recognised compliance route at £4.66/litre for the main obligation and £4.93/litre for the PtL obligation. Paying buy-out does not reduce a supplier's RCM levy exposure, and at scale it represents a significant cash outflow exceeding the delivered cost of HEFA SAF under most current market conditions. Buy-out is best used as a tactical backstop for specific volume shortfalls, not as a primary compliance strategy.


How much SAF will the UK need in 2030 to hit the 10% mandate target?

The UK Department for Transport estimates that a 10% obligation in 2030 equates to approximately 1.5 billion litres of SAF annually, based on projected UK aviation fuel demand. Of this, approximately 74.74% of the main obligation can come from HEFA, with the remaining volume requiring non-HEFA pathways. The separate PtL sub-obligation of 0.5% must be met exclusively through Power-to-Liquid fuel.


When does the Power-to-Liquid obligation start and what does it mean for procurement strategy?

The PtL sub-obligation begins at 0.2% of obligated fuel in 2028, rising to 0.5% in 2030 and 3.5% by 2040. PtL has a separate, higher buy-out price of £4.93/litre and a modelled 2030 median production cost of £4,425/tonne — 3.76 times the HEFA median. Given the multi-year lead times associated with non-standard SAF project financing and commissioning, procurement discussions for PtL supply should begin now rather than in 2027 or 2028.


Will there be enough non-HEFA SAF supply for UK fuel suppliers to meet the 2030 mandate?

This remains an open question — acknowledged as such by the UK government's own June 2026 call for evidence on SAF supply and industry certainty. Domestic non-HEFA projects supported through the Advanced Fuels Fund total approximately 286.7 kt/y of stated capacity, against a 2030 total SAF requirement of approximately 1.5 billion litres. Dentons' 2025/2026 SAF analysis estimates that 5.8 Mt of additional SAF capacity must reach Final Investment Decision in 2026–2027 — a target the current project pipeline has not demonstrably met.


What is the UK SAF Mandate buy-out price in 2026?

The buy-out price in 2026 is £4.66/litre for the main obligation. There is no PtL sub-obligation in 2026 — the PtL buy-out rate of £4.93/litre applies from 2028 when the PtL obligation begins. These figures are confirmed in the DfT SAF Mandate Compliance Guidance 2026.
