NEW HMRC ADVISORY FUEL RATES
If you run a business with company cars, or if you reimburse employees for business mileage in a company vehicle, HMRC has just updated its Advisory Fuel Rates — the new rates apply from 1 September 2026 until 30 November 2026.
Advisory fuel rates are the approved per-mile rates that employers can use when reimbursing employees for fuel used on business trips in a company car, or when employees need to repay the cost of private fuel provided by their employer.
The rates from 1 September 2026 are:
• Petrol: 14p per mile (up to 1400cc) • 17p (1401–2000cc) • 27p (over 2000cc)
• Diesel: 15p per mile (up to 1600cc) • 16p (1601–2000cc) • 22p (over 2000cc)
• LPG: 11p • 13p • 20p per mile
For electric company cars, HMRC has for the first time introduced a two-tier rate:
• 7p per mile when charged at home
• 15p per mile when charged at a public charge point
This split reflects the real-world difference in electricity costs between home and public charging — and is a practical change for businesses running electric fleets.
Using the correct rates matters: reimbursing above the advisory rate without justification may result in a taxable benefit for the employee. Reimbursing below the rate means the employee may be able to claim tax relief on the shortfall.
