The question

To ask the Secretary of State for Transport, what steps she is taking to secure capital investment in sustainable aviation fuel.

Answered by Mike Kane

We are supporting investments in UK sustainable aviation fuel “SAF” production facilities through the Advanced Fuels Fund (AFF). We extended this funding for a further year through the Autumn Budget, investing an additional £63 million, and the Spending Review 2025 will continue support for SAF production in the UK to 2029/30.

In addition to providing grant funding under the AFF our SAF Bill, currently before the House, will deliver a SAF Revenue Certainty Mechanism. This mechanism will help unlock investment in UK SAF production and grow this emerging sector.

We are also encouraging the production and use of sustainable aviation fuels in the UK through a SAF Mandate. The mandate, one of the first pioneering policies of its kind, came into force on 1st January 2025 and increases investor certainty by building domestic demand for SAF.
