TL;DR: The UK's 5p fuel duty cut is set to be reversed by March 2027, leading to higher petrol and diesel prices UK-wide. While a new 'Fuel Finder' scheme aims to help drivers save, a new EV mileage tax of 3p per mile will begin in April 2028, adding hundreds to annual motoring costs for electric car owners.
Key Facts
- February 2026: The Competition and Markets Authority introduced a mandatory 'Fuel Finder' map scheme requiring petrol stations to report live prices.
- March 2027: The fuel duty freeze end date is set, with the rate returning to 57.95p per litre after a six-month phased increase.
- £40: The estimated annual saving for an average driver who uses the new government-backed fuel price comparison tool.
- April 2028: The new EV mileage tax begins, charging battery electric vehicle drivers 3p for every mile they drive.
- 60%: The approximate percentage of the price you pay for a litre of fuel that goes directly to the Treasury in tax.
Confused about the latest UK fuel duty changes and what they mean for your wallet? You're not alone. While a temporary reprieve is in place, the long-term outlook for petrol, diesel, and even electric car owners involves significant new costs you need to know about.
Let’s be honest—keeping track of what we pay at the pump feels like a full-time job lately. Between fluctuating global oil prices and the Treasury's shifting targets, the cost of getting from A to B is rarely stable. The latest updates suggest a bit of a mixed bag for our wallets, with some short-term help but a much more expensive long-term outlook for everyone on the road.
Will the New 'Fuel Finder' Scheme Actually Save You Money?
Yes, the government believes the new scheme will save drivers money by increasing competition. If you’ve felt like local forecourts are taking liberties with their pricing, you’re not alone. As of last week, new Competition and Markets Authority fuel rules force petrol stations to report live prices to a centralised database.
This data will power a 'Fuel Finder' map scheme, which aims to spark some much-needed competition among retailers. Will it actually work? The government reckons it could save the average driver about £40 a year by making it easier to hunt down the cheapest litre in town. It puts the power back in your hands to avoid the priciest pumps.
But Here’s the Big Catch: When Does the Fuel Duty Freeze End?
The temporary 5p fuel duty cut will be fully reversed by March 2027. While the government extended the relief we’ve enjoyed since 2022 until September 2026, they’ve already mapped out its demise. Instead of a sharp shock, we’ll see a staggered hike over six months. By March 2027, the fuel duty freeze end date will pass, and the duty will climb back to 57.95p per litre.
How Much Tax Are You Really Paying Per Litre?
When you layer the mandatory 20% VAT on top of that duty, the taxman ends up taking a massive chunk of your change. The numbers are frankly eye-watering. For example, if you’re paying 131.9p for petrol, the average fuel tax per litre is around 80p. That leaves just 52p to cover the actual fuel, shipping, and the retailer's profit.
The RAC has been vocal about this too, pointing out that over 60% of our spend on petrol and diesel prices in the UK goes straight to the Treasury. It makes you wonder—is it finally time to ditch the petrol engine altogether?
Thinking of Switching to an EV? Not So Fast...
If you’re thinking that switching to a battery-powered car is a total escape from these UK fuel duty changes, I have some sobering news. The government needs to plug a £40bn hole as fuel duty revenue dries up, and their solution is the EV mileage tax 2028.
Starting in April 2028, this new plan will charge drivers based on distance:
- Battery Electric Vehicles (BEVs): Charged 3p for every mile driven.
- Plug-in Hybrids (PHEVs): Charged a slightly lower rate of 1.5p per mile.
For a typical driver doing 10,000 miles a year in a pure EV, that’s an extra £300 bill annually—and that’s before they start inflation-linking the rates. We’ve already seen London’s Congestion Charge scrap the 'free ride' for EVs, and this nationwide mileage tax is the next logical, if painful, step.
Whether you’re sticking with a reliable diesel or eyeing up a second-hand Tesla, the reality is that the cost of motoring is only heading in one direction. Staying informed about these changes is the only way to avoid a nasty surprise when you check your bank balance.
