• Published: 22 June 2026

Summary

Seeks further views on how the sustainable aviation fuel (SAF) revenue certainty mechanism (RCM) levy could operate in the UK.

This consultation closes at
11:59pm on 2 August 2026

Consultation description

Government has previously confirmed that industry should fund the revenue certainty mechanism (RCM) through a variable levy on aviation fuel suppliers.

Following our first consultation on the sustainable aviation fuel (SAF) RCM levy design, we seek further views on how the levy could operate, including:

• how individual levy contributions are determined and collected
• how the reserve is collected
• how over-collected amounts and surpluses could be returned to suppliers

As part of this consultation, we also seek views on our intention to update the definition of a support scheme under the multiple incentives rules in the SAF Mandate legislation to ensure that SAF produced under the RCM is also eligible to receive SAF Mandate certificates.
