HMRC Fuel Rate Hikes: What Petrol, Diesel, and Electric Car Owners Need to Know (2026)

Hold onto your wallets, drivers! HM Revenue and Customs (HMRC) is rolling out new fuel rates today, and they could significantly impact how much you pay to keep your vehicle on the road. Whether you drive a petrol, diesel, or electric car, these changes are worth paying attention to. But here's where it gets controversial: electric vehicle (EV) owners will see a slight increase in public charging costs, while home charging rates remain unchanged. Is this a fair move, or does it disproportionately affect certain drivers? Let’s dive in.

Starting today (Sunday, March 1), HMRC’s updated advisory fuel rates (AFRs) come into effect. These rates are crucial because they determine how employees are reimbursed for business travel in company cars or how they repay fuel costs for private use. And this is the part most people miss: the rates are recalculated four times a year, ensuring they reflect current fuel prices—though not everyone realizes how often these changes occur.

The latest update includes several price adjustments, particularly for electric and liquefied petroleum gas (LPG) vehicles. Notably, HMRC has separated EV rates based on charging location. If you charge your EV at home, the rate remains at 7p per mile, but if you rely on public chargers, you’ll now pay 15p per mile—up from 14p. This distinction raises questions: Are public chargers becoming less affordable, and how will this affect EV adoption?

For petrol and diesel drivers, the rates remain unchanged. Here’s the breakdown:

Petrol Vehicles:
- Engines up to 1,400cc: 12p per mile
- Engines between 1,401cc and 2,000cc: 14p per mile
- Engines over 2,000cc: 22p per mile

Diesel Vehicles:
- Engines up to 1,600cc: 12p per mile
- Engines between 1,601cc and 2,000cc: 13p per mile
- Engines over 2,000cc: 18p per mile

LPG vehicles, though less common, also saw rate reductions. For example, engines over 2,000cc will now be reimbursed at 19p per mile, down from 21p. Is this a sign that LPG is becoming less popular, or is it simply a reflection of market trends?

These rates are calculated using data from various sources, including the Department for Energy Security and Net Zero (DESNZ) for petrol and diesel, and the Automobile Association for LPG. Electric vehicle data is sourced from DESNZ, the Office for National Statistics, and the Department for Transport, ensuring a comprehensive approach.

Looking ahead, HMRC will release the next update on June 1, followed by further changes in September and December. But here’s the bigger question: As fuel costs continue to fluctuate, how will these frequent updates impact drivers’ budgets and travel habits?

In related news, motorhome and campervan drivers may face permanent coastal bans under new proposals, while Chinese vehicle owners are seeing a staggering 242% increase in car insurance costs. Additionally, motorists risk automatic MOT failure and a £1,000 fine for not adhering to updated number plate rules. With so many changes on the horizon, is the cost of driving becoming unsustainable for some?

What do you think about the new advisory fuel rates? Are they fair, or do they unfairly target certain drivers? Share your thoughts in the comments below—we’d love to hear your perspective!
