The honest numbers
Average fully comprehensive EV insurance in the UK sits at roughly £654 per year in 2026. The equivalent petrol car comes in at around £551–£607, depending on make and model. That's a gap of 10–15%: noticeable, but not the deal-breaker some headlines suggest.
The gap has narrowed over the past two years as more insurers have built EV expertise, more repair shops have tooled up, and claims data has matured. But it's still there, and it's worth understanding why.
Why EV insurance costs more
Five factors drive the premium difference:
Repair costs are higher. Thatcham Research data shows EV repairs cost roughly 25% more than equivalent petrol car repairs. Structural battery enclosures, high-voltage cabling, and lightweight body panels all need specialist handling.
Repairs take longer. EV repairs take around 14% longer on average. Longer repair times mean longer courtesy car provision, which pushes up insurers' costs.
Battery replacement is expensive. A new battery pack costs anywhere from £5,000 to £15,000 or more depending on the car. Even a minor impact to the battery enclosure can trigger a full replacement if the insurer can't confirm the cells are undamaged.
Fewer specialist repair shops. Not every body shop is equipped to work on high-voltage vehicles. Limited supply of qualified repairers means less price competition on labour.
Higher purchase prices. Used EVs still tend to cost more than petrol equivalents, and higher replacement value means higher premiums.
Which used EVs are cheapest to insure
Insurance group matters more than brand. Lower-value, lower-performance EVs sit in lower groups and attract cheaper premiums:
Lower insurance groups: the VW e-Up!, Renault Zoe, Nissan Leaf, and MG ZS EV all sit in relatively modest insurance groups. These are among the cheapest used EVs to insure in the UK.
Higher insurance groups: the Tesla Model 3 and BMW i3 sit higher, partly because of parts cost and partly because of performance. A Long Range Tesla Model 3 can be two or three insurance groups above a base Nissan Leaf.
Check individual car pages for the insurance group of each model and what that means for your total monthly cost.
How to reduce your premium
Compare widely. EV insurance pricing varies enormously between providers. Some insurers have invested in EV claims data and price competitively; others haven't and charge a blanket premium. Always compare at least five quotes.
Consider telematics (black box) insurance. If you're a careful driver, a telematics policy can cut your premium significantly. EVs' smooth driving characteristics tend to score well on telematics metrics.
Increase your voluntary excess. Raising your voluntary excess from £250 to £500 can reduce your annual premium noticeably. Only do this if you can comfortably afford the higher excess in the event of a claim.
Install a home charger. Some insurers view a home charger positively: it means the car is parked on a driveway or in a garage overnight rather than on the street, which lowers theft and vandalism risk.
Take an advanced driver course. Pass Plus or IAM RoadSmart qualifications are recognised by many insurers and can earn a discount.
Multi-car policies. If your household has more than one vehicle, a multi-car policy often works out cheaper than insuring each car separately.
Specialist EV cover to look for
Standard motor policies cover the basics, but EV-specific add-ons are worth checking:
Battery protection. Some policies explicitly cover battery degradation below a certain health threshold, or guarantee replacement if the battery is damaged beyond economical repair.
Charging cable cover. Charging cables cost £200–£500 to replace and are a common target for theft. Not all standard policies cover them as standard.
Recovery to a charging point. If your EV runs out of charge, some policies include flatbed recovery to the nearest charger rather than just the nearest garage.
Hire car while charging. If your car is off the road for repairs, some EV-specialist policies provide an electric courtesy car so you're not stuck with a petrol hire car and unfamiliar running costs.
Insurance in the total cost picture
Insurance is one line in your monthly running cost, and it's worth keeping it in perspective. Even at £654 a year, that's roughly £55 a month. For most drivers who charge at home, the fuel savings alone more than offset the insurance premium difference.
A typical used EV driver with home charging saves £80–£120 a month on fuel compared to petrol. Subtract the extra £8–£12 a month for higher insurance and you're still well ahead. The insurance gap is real but it doesn't break the economics.
