Biofuels and fuel substitutes: key changes from Excise Notice 179e (2022 update)
This explainer summarizes the UK HMRC guidance on biofuels and other fuel substitutes under Excise Notice 179e, effective from 1 April 2022. It explains definitions, who must follow the rules, and what to do next if you deal with biofuels or fuel substitutes.
What the notice covers and why it matters
The notice defines what counts as a biofuel or fuel substitute for tax purposes and outlines the excise duty rules that apply. It also describes producers’ responsibilities and how duties are calculated. Updates over time can adjust definitions, contact points, and obligations, so anyone involved in producing, supplying, or using biofuels should verify current guidance.
Key facts you should know
Key terms include biofuel products and fuel substitutes. Biofuels are liquid or gaseous fuels derived from biological sources used to power vehicles or heat. Fuel substitutes are products that HMRC treats similarly for excise purposes. The notice details who is liable for duty, how rates are set, and the producer’s responsibilities to keep records. Updates in 2025–2026 adjusted contact points and definitions to reflect changes in hydrocarbon oil duties law.
Who is affected
Producers of biofuel products and fuel substitutes, suppliers who move or sell these fuels, and users who select biofuels for vehicles or heating may be affected. The guidance covers obligations for those who produce, import, or use such fuels to ensure correct excise duty handling and compliance with reporting requirements.
Practical next steps
If you work with biofuels or fuel substitutes: review the latest Excise Notice 179e to confirm definitions and duties; check your records and product classifications against the notice; ensure your contact points with HMRC are up to date. If you are unsure of how a product is classified, seek guidance from HMRC or consult a tax professional familiar with hydrocarbon oil duties.
