HMRC holds petrol and diesel mileage rates steady, trims LPG and public EV charging allowances from 1 March 2026

HM Revenue and Customs has published its quarterly Advisory Fuel Rates and Advisory Electric Rates effective 1 March 2026, leaving petrol and diesel reimbursement rates unchanged while reducing LPG rates across all engine sizes and adjusting public electric charging allowances. The rates, reviewed every quarter, guide employers and fleet operators on tax efficient mileage payments for company vehicles. Employers may continue using the previous rates for up to one month after the new figures take effect.

Why it matters: Fleet operators managing mixed or electrified company car programmes must update reimbursement policies to stay compliant and control costs. Stability in petrol and diesel rates offers administrative continuity, but the trim to public EV charging allowances may influence how businesses structure charging support for drivers on the road.
