Sustainable Aviation Fuel: UK SAF Mandate and Revenue Certainty Mechanism

21 May 2025

The UK's new SAF Mandate came into effect on 1 January 2025, following an extensive consultation process and much anticipation. The SAF Mandate is expected to unlock investment in the sustainable aviation fuel (SAF) supply chain, including production projects, by legally mandating gradually increasing levels of demand from jet fuel suppliers across the UK's aviation industry.

The Government also recently confirmed details of the proposed SAF Revenue Certainty Mechanism (RCM) for producers in the UK. Framework legislation was proposed to Parliament on 14 May 2025 and is expected to become law by the end of 2026. The RCM is expected to be the final key policy tool designed to kickstart the SAF industry in the UK.

In this briefing, we look at the SAF Mandate and RCM and consider their impact.
