Electric car insurance UK: every model's group, what it costs, and how to save

The honest numbers (2026 update)

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 to £607, depending on make and model. That's a gap of roughly 1 to 5 per cent for most models, down from 13 per cent just two years ago.

The gap has narrowed significantly as more insurers have built EV claims expertise, more body shops have invested in high-voltage training, and the repair parts supply chain has matured. For budget-friendly models like the Nissan Leaf or Renault Zoe, the gap is now close to zero. For higher-performance models like the Tesla Model 3 Long Range, it remains wider because of parts cost and repair complexity.

The headline? EV insurance is not the deal-breaker that older articles suggest. It is still slightly higher on average, but for most used EVs the difference adds less than £10 per month to your running costs.

Insurance groups for every popular used EV

Insurance groups run from 1 (cheapest to insure) to 50 (most expensive). The group is set by the Association of British Insurers and Thatcham Research based on purchase price, repair cost, performance, safety features, and parts availability. A lower group does not guarantee a lower premium, but it is the single strongest predictor.

The table below covers all 18 popular used EVs available through HonestRange, sorted from cheapest to most expensive to insure. Premiums shown are typical 2026 comprehensive quotes for a 30-to-50 year old driver with a clean licence and three or more years of no-claims bonus. Your actual quote will vary based on location, annual mileage, and personal circumstances.

Why EV insurance costs more than petrol

Five factors explain the premium difference. Understanding them helps you pick a model and policy that minimises the gap.

1. 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 aluminium or composite body panels all need specialist handling and materials.

2. Repairs take longer. EV repairs take around 14% longer on average. Longer repair times mean longer courtesy car provision and higher storage costs, both of which push up insurers' claim costs.

3. 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 cannot confirm the cells are undamaged. This is the single biggest cost risk insurers price into EV premiums.

4. Fewer specialist repair shops. Not every body shop is equipped to work on high-voltage vehicles. Limited supply of qualified repairers means less competition on labour rates. This is improving year on year, but the gap has not fully closed.

5. Higher purchase prices. Even on the used market, EVs tend to cost more than their petrol equivalents. Higher replacement value means higher premiums, because the insurer's maximum payout in a total loss is higher.

The five cheapest used EVs to insure in the UK

If keeping insurance costs low is a priority, these five models offer the best combination of low insurance group, affordable parts, and modest performance.

1. Dacia Spring (group 8 to 12). The cheapest EV to insure in the UK by a wide margin. Its low purchase price, small battery, and modest performance keep it in single-digit insurance groups. Typical premiums run £350 to £450 per year. For city driving on a budget, this is hard to beat on total cost.

2. Renault Zoe (ZE50) (group 14). A well-established model with plentiful parts supply and a wide network of experienced repairers. Group 14 puts it firmly in affordable territory, with premiums typically £400 to £500. The Zoe's popularity works in your favour here: insurers have deep claims data, which means better pricing.

3. VW e-Golf (group 15 to 18). Built on the standard Golf platform, which means body panels and non-drivetrain parts are shared with one of the most common cars on UK roads. That parts commonality keeps repair costs and insurance groups low. Expect £400 to £500 per year.

4. Nissan Leaf (40 kWh) (group 21 to 24). The UK's best-selling EV historically. Huge parts availability, thousands of trained technicians, and mature claims data all work to keep premiums reasonable at £420 to £520. Group 21 to 24 is comparable to a mid-range petrol hatchback.

5. Kia Soul EV and VW ID.3 (group 18 to 24 / 18 to 29). These two share the fifth spot. The Kia Soul EV sits in groups 18 to 24, while the VW ID.3 ranges from 18 to 29 depending on trim. Base-spec ID.3 Pro models in group 18 are among the cheapest family-sized EVs to insure. Premiums for both typically fall between £450 and £600.

Most expensive used EVs to insure

At the other end of the scale, three models stand out for higher insurance costs. If you are buying one of these, budget accordingly and use the saving tips below to bring the premium down.

Tesla Model 3 Long Range and Standard Range Plus (group 48 to 50). The highest insurance groups of any popular used EV. Three things drive this: the dual-motor Long Range variant's high performance (0 to 60 in 4.2 seconds), Tesla's proprietary parts supply chain which limits repair competition, and the structural battery pack design which makes even minor underbody impacts expensive to assess. Typical premiums run £800 to £1,100 per year. That said, Tesla drivers who use telematics policies and have clean records often quote well below these averages.

BYD Atto 3 (group 38). BYD is relatively new to the UK market, which means a thinner parts supply chain and fewer trained repairers. Group 38 reflects that uncertainty. As BYD's UK presence matures and parts become more readily available, this group is likely to come down. Current premiums sit around £600 to £750.

BMW i3 (42 kWh) (group 28 to 34). The i3's carbon fibre reinforced plastic (CFRP) body is lightweight and strong, but repairing it requires specialist equipment and materials. Standard body shops cannot work on CFRP panels, which limits repair options and pushes up costs. Premiums typically range from £550 to £700.

Nine ways to reduce your EV insurance premium

You cannot change your car's insurance group, but you can influence almost every other factor that determines your premium. These nine steps, used together, can reduce your annual cost by 20 to 30 per cent.

1. Compare at least five quotes. EV insurance pricing varies enormously between providers. Some insurers have invested heavily in EV claims data and price competitively. Others have not and charge a blanket premium to cover their uncertainty. Use at least two comparison sites (such as Compare the Market and GoCompare) and get direct quotes from LV=, Admiral, and Direct Line, all of which have dedicated EV products. The spread between cheapest and most expensive quote for the same driver and car can be £200 or more.

2. Pay annually, not monthly. Monthly payment plans typically add 10 to 15 per cent APR on top of the annual premium. On a £654 policy, that's £65 to £98 in unnecessary interest. If you can afford to pay in full up front, do so. Some providers offer interest-free monthly payments, but these are rare.

3. Use telematics (black box) insurance. If you are a careful driver, a telematics policy can deliver significant savings. EVs tend to score well on telematics metrics because regenerative braking encourages smooth deceleration, instant torque promotes steady acceleration rather than aggressive revving, and the absence of gear changes reduces jerky driving patterns. Providers like By Miles and Veygo offer EV-friendly telematics options.

4. Increase your voluntary excess to £500. Raising your voluntary excess from the typical £250 to £500 signals to insurers that you are less likely to make small claims. This routinely saves £30 to £60 per year. Only do this if you can comfortably cover the higher excess in the event of a claim.

5. Install a home charger and park off-street. Some insurers view a home charger positively because it means the car is parked on a driveway or in a garage overnight rather than on the street. This lowers theft and vandalism risk. If you already charge at home, make sure your insurer knows you park off-street. It is a simple detail that can move the needle.

6. Consider a multi-car policy. If your household has more than one vehicle, a multi-car policy often works out 10 to 15 per cent cheaper than insuring each car separately. Admiral, LV=, and Direct Line all offer multi-car discounts.

7. Take an advanced driver course. Pass Plus and IAM RoadSmart qualifications are recognised by many insurers and can earn a discount of 5 to 10 per cent. Pass Plus costs around £150 to £200 and is usually completed in a day. The discount often pays for itself within two years.

8. Add an experienced named driver. Adding an older, experienced driver to your policy (a partner or family member with a long clean record) can sometimes reduce the overall premium. This works because insurers assess the risk profile of all named drivers. Do not add someone who will not genuinely drive the car, as this is called "fronting" and invalidates your policy.

9. Use specialist EV insurers. Several UK insurers now offer dedicated EV products with tailored pricing. LV= has an EV-specific policy with battery cover included. Admiral offers EV add-ons and has invested in EV claims expertise. Direct Line provides specialist EV cover with charging cable protection as standard. Octopus Energy also partners with insurance providers to offer bundled home energy and car insurance deals for EV owners. These specialist products often undercut generic quotes because the insurer understands the actual risk rather than pricing for worst-case uncertainty.

Specialist EV cover features to look for

Standard motor policies cover the basics, but several EV-specific features are worth checking before you buy. Not all policies include these as standard, so ask explicitly or read the policy wording.

Battery protection. The most important EV-specific cover. Some policies explicitly protect against battery degradation below a certain health threshold (typically 70% state of health) or guarantee replacement if the battery is damaged beyond economical repair. Given that battery packs cost £5,000 to £15,000, this cover provides genuine peace of mind. LV= and Direct Line both include battery protection in their EV policies.

Charging cable cover. Charging cables cost £200 to £500 to replace and are a common target for theft, especially portable granny cables left in the boot. Not all standard policies cover them. Check whether your policy covers cables both at home and at public chargers, and whether there is a sub-limit.

Recovery to a charging point. If your EV runs out of charge, some policies include flatbed recovery to the nearest compatible charger rather than just the nearest garage. This is more useful than it sounds: a standard recovery to a petrol station is no help when you are driving an EV.

EV courtesy car. If your car is off the road for repairs, some EV-specialist policies provide an electric courtesy car so you are not stuck with an unfamiliar petrol hire car and unexpectedly higher fuel costs. This is a relatively new feature and not yet widely available, but Admiral and LV= both offer it on some policies.

Insurance in the total cost picture

Insurance is one line in your monthly running cost, and it is worth keeping in perspective. Even at £654 a year, that is 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 to £120 a month on fuel compared to petrol. Subtract the extra £5 to £12 a month for slightly higher insurance and you are still well ahead. The insurance gap is real but it does not break the economics of going electric.
