Electric car insurance in the UK has never been closer to petrol-car pricing - but the premium is still worth understanding before you buy. In 2026 the average comprehensive EV premium sits at roughly £558 to £654 a year, around 10-15% more than an equivalent petrol model. That gap has narrowed sharply from the 25% peak insurers saw in 2024.
How much does EV insurance cost in 2026?
Independent cost indexes put the average UK electric car premium in a consistent range this year:
- £558 - average EV premium (MoneySuperMarket Electric Car Insurance Index 2026)
- £587 - average EV premium (Compare the Market, July 2026)
- £654 - average EV premium (Brumble analysis of ABI and DfT data)
- 10-15% - typical premium gap vs an equivalent petrol car, down from 25% in 2024
For context, average petrol and diesel premiums run from about £509 to £607 depending on the source. Electric cars now also beat petrol on total running costs: charging averages £483 a year versus £963 on fuel, according to Compare the Market research published in July 2026.
Typical premiums by model
Not all EVs cost the same to insure. Small, lower-value models are close to petrol equivalents, while premium performance cars sit in the highest insurance groups. Based on the MoneySuperMarket 2026 index, here is how popular models compare:
| Model | Average annual premium |
|---|---|
| Renault R5 | £417.64 |
| MINI Cooper S Level 2 | £445.58 |
| Tesla Model 3 Performance | £799.29 |
| Tesla Model 3 Long Range AWD | £801.74 |
| Audi e-tron Quattro 50 | £838.32 |
| BYD Seal Excellence | £853.55 |
| Tesla Model 3 Standard Range Plus | £868.37 |
| Tesla Model Y Standard Range | £878.14 |
| Tesla Model Y Long Range AWD | £895.76 |
| Jaguar I-Pace 400 SE | £921.59 |
High-performance models such as the Tesla Model Y or Porsche Taycan can go much higher - specialist insurers commonly quote £1,300 to over £1,500 for the fastest trims.
Why are EVs more expensive to insure?
There are four main reasons insurers charge more for electric cars:
- The battery - typically 30-50% of the vehicle's value and expensive to repair or replace
- Specialist repair - EV repairs need trained technicians and, in many cases, manufacturer-approved parts
- Higher vehicle values - even mainstream EVs cost more than equivalent petrol hatchbacks
- Performance - rapid acceleration in cars like the Model 3 or Ioniq 5 pushes them into higher insurance groups
Which EVs are cheapest to insure?
Small, affordable EVs are now essentially at parity with petrol. The Dacia Spring can be insured for under £500 a year, and for models like the Nissan Leaf and MG4 EV premiums are comparable to petrol equivalents of similar size, according to Brumble's 2026 analysis. If insurance cost is a priority, the cheapest cars to insure are almost always the cheapest to buy.
How to save on EV insurance
- Shop around - do not auto-renew; compare quotes from at least three insurers (Compare the Market says switching is the single biggest saving)
- Raise your voluntary excess - a higher excess can cut the premium noticeably, but only set it at a level you can afford
- Keep mileage realistic - lower annual mileage estimates reduce risk and price
- Consider telematics - black-box policies reward careful driving and low mileage
- Pay annually - monthly instalments include interest; paying in full saves 10-20%
- Park securely - a driveway or garage lowers theft risk, which matters for EVs with expensive batteries
The gap is closing
EV insurance is still slightly pricier than petrol, but the trend is firmly downwards. The premium gap fell from roughly 30% in 2023 to 10-15% in 2026 as insurers built up battery-repair and theft data. With EVs now taking more than a quarter of UK new car registrations, expect the gap to keep closing.
