Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate her Department has made of the impact of the Sustainable Aviation Fuel Mandate on average airline ticket prices in (a) 2025, (b) 2026 and (c) each of the next ten years.

I refer the hon Member to the answer I gave on 23 October 2025, to Question UIN 78707 page 61 of the Sustainable Aviation Fuel Mandate Final stage Cost Benefit Analysis, covers estimates on air fares.

We recognise the importance of protecting consumers from excessive costs, and this principle is embedded in both the SAF Mandate and the Revenue Certainty Mechanism.

The SAF Mandate includes a built-in review process, enabling Government intervention if costs become excessive. Meanwhile, the Revenue Certainty Mechanism helps reduce the cost of producing SAF in the UK by lowering the cost of capital for domestic plants.

To ensure the Mandate remains aligned with technological and commercial developments, it will be continuously monitored, including its impact on consumers. Formal reviews will be published at least every five years, with the first scheduled for 2030. These reviews will also ensure continued alignment with broader government policies and strategies.
