The UK aviation market received 292 million litres of sustainable aviation fuel (SAF) between January 1 and August 15, accounting for around 3.92% of total aviation fuel use during the period, according to preliminary data released by the Department for Transport on September 17, Ethanol Producer Magazine reported.
The data represents the first provisional report on the UK’s 2026 SAF mandate. All SAF supplied during the seven-and-a-half-month period was classified as regular SAF, with no power-to-liquid (PtL) SAF supplied to the market.
The Department for Transport plans to publish additional provisional reports on 2026 SAF use periodically. Final data for the full year is scheduled to be released in November 2027.
The latest figures follow the department’s fifth provisional report on 2025 SAF data, released in July. According to that report, 333 million litres of SAF was supplied to the UK market during 2025, representing 2.26% of total aviation fuel consumption for the year.
All 333 million litres supplied in 2025 were also classified as regular SAF. Final data for 2025 is expected to be published by the Department for Transport in November.
The increase in SAF’s share of UK aviation fuel use in the first seven-and-a-half months of 2026 reflects the implementation of the country’s SAF mandate, although the latest figures show that power-to-liquid fuels have yet to enter the UK market in significant volumes.
