Question to the Department for Transport:

To ask the Secretary of State for Transport, with reference to Clauses 6, 12 and 13 of the Sustainable Aviation Fuel Bill, what estimate she has made of the total cost to (a) passengers, (b) taxpayers, and (c) fuel suppliers arising from revenue certainty contracts and associated levy payments; and what steps she is taking to ensure that this support does not (i) create long-term subsidy dependence and (ii) disproportionately benefit overseas producers.

Answered by Keir Mather - Parliamentary Under-Secretary (Department for Transport)

The Government set out the potential costs and benefits arising from the RCM scheme in the Cost-Benefit Analysis, published in May 2025, including potential costs for passengers and fuel suppliers. The scheme will be funded via a variable levy placed on aviation fuel suppliers, not by the taxpayer.

The RCM contracts will only be signed with UK-based SAF producers. These contracts will have a defined term length to ensure a clear end date to the subsidy and also sets a cap on the support for the sales of SAF to control the scale of the scheme. In addition, clause 1 (7) of the SAF Bill provides an end date, 10 years from the day on which the Act is passed, to new contracts being entered into.

We expect UK SAF production to be internationally competitive, with the RCM playing a key role to attracting investment for UK producers in a nascent market that is using innovative technologies. Whilst we are designing contracts, there is careful consideration towards how the volumes are sold under the RCM, including who are the offtakers and the end user’s location.

Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate she has made of the potential impact of (a) the Sustainable Aviation Fuel Bill and (b) the proposed Revenue Certainty Mechanism on average passenger air fares by 2030 and 2035; and whether passengers will be informed of any additional levies or costs arising from the scheme.

Answered by Keir Mather - Parliamentary Under-Secretary (Department for Transport)

The Sustainable Aviation Fuel (SAF) Bill provides the legislative basis for the SAF Revenue Certainty Mechanism (RCM). The RCM will help producers get the investment they need to ramp up the production of SAF in the UK.

The Government published a Cost Benefit Analysis for the SAF RCM in May 2025. We expect the RCM to cause ticket prices to increase or decrease by up to £1.50 on an average ticket per year, which is expected to be within the range of normal year to year changes in air fares.

The Government has confirmed that the RCM will be funded via a variable levy on aviation fuel suppliers and will look to design the levy in a way that ensures transparency of costs. The Government will actively monitor and control scheme costs including through the setting of strike prices and by controlling the scale and number of contracts awarded.
