New Carbon Brief analysis finds UK electric vehicles are now up to nine times cheaper to drive than petrol or diesel cars, based on current fuel prices. Off-peak home charging works out at 2.3p per mile, while petrol costs around 20.1p and diesel 21p per mile. Even at the domestic price cap, EVs cost roughly 7p per mile, still three times cheaper than fossil fuel cars. The running cost gap has widened because oil prices jumped above $100 a barrel after Middle East tensions and strikes on Russian refineries pushed up petrol and diesel prices. Carbon Brief estimates EV drivers now save around £1,200 a year in fuel costs. Battery EVs are only 6% of UK cars on the road, but they made up about 30% of new car sales in August, so the fleet is shifting gradually. Public charging remains more expensive, though around 90% of EV charging happens at home.

Good breakdown of running costs. The 2.3p per mile off-peak figure is the real story, but the 90% home charging stat matters just as much. Public charging is still pricey, so anyone without a driveway or off-street parking is not getting the same deal. That gap is where policy should focus.

Nine times cheaper only holds if you can charge at home on an off-peak tariff. For apartment dwellers or people on street parking, public charging rates are a different picture. Also worth noting the 3p per mile EV tax from 2028 barely dents the gap, but it is a sign of how the revenue question is going to grow.

The article is right about fuel cost, but it skims over why electricity prices are tied to gas. The January 2027 price cap rise is a direct consequence of gas setting the marginal price. Cheaper to drive an EV today, yes, but the bigger win is decoupling electricity from gas so the next fuel spike does not land on EV drivers.

Useful numbers here. The 30% BEV share of new sales in August matters more than the 6% fleet share. The fleet will turn over slowly, but the running cost gap is now so wide that the used market argument for petrol is getting harder to make. Watch the 2028 pay-per-mile tax, though.
