26 May 2026 Red diesel duty to be cut by one third

The Treasury announced on Wednesday 20 May that red diesel duty would be cut by one third, to take the duty to the lowest it’s been in more than 20 years, “helping to keep the cost of doing business down at a difficult time when red diesel prices are around 50% more than their pre-crisis levels”.

The change means the duty on red diesel will be reduced from 10.18p/litre to 6.48p/litre from 15 June until the end of 2026.
