Cheapest Electric Cars to Insure in the UK

The Renault R5 E-Tech is the cheapest mainstream electric car to insure in the UK in 2026, with an average annual premium of just £418 (MoneySuperMarket Electric Car Insurance Index, 2026). The Dacia Spring has the lowest insurance group of any EV on sale — groups 8 to 12 — with premiums starting below £400 for many driver profiles. At the opposite end, premium EVs from Tesla, BMW and Porsche regularly attract premiums of £1,500 to £2,500 per year.

Understanding why some EVs insure cheaply — and which ones to target if low insurance is a priority — requires looking beyond the sticker price.

Why does EV insurance cost differ so much between models?

Insurance groups run from 1 (cheapest) to 50 (most expensive). Group assignments are made by Thatcham Research, based on repair cost, parts cost, vehicle value, safety performance, and security. For EVs, the high-voltage battery is a dominant factor: a car with a large, expensive battery pack that requires a full replacement after even minor accident damage will sit in a higher group than a small, cheap EV where battery costs are proportionate.

Other key factors:

• List price: Higher-value cars cost more to replace, pushing groups up
• Performance: High-powered variants sit in higher groups
• Repair network availability: EVs with limited approved repairer networks have higher claim costs
• Parts supply chain: Models with better UK parts availability have lower labour costs and shorter repair times

The Dacia Spring: lowest insurance group of any EV

The Dacia Spring sits in insurance groups 8 to 12 — lower than almost any petrol car of comparable size, let alone any EV. Its low purchase price (from £12,440) means the insurer’s maximum liability in a write-off is modest, and its simple battery system and modest performance keep repair costs in check.

For price-sensitive buyers in cities, the Spring’s insurance costs can be under £400 per year. The trade-off is capability: 30 kW maximum DC charging, 140 miles real-world range, and a modest feature set. For drivers who need a city runabout and want the lowest possible total running cost, it is hard to beat.

The Renault R5: best combination of affordability and insurance

The R5 achieves something unusual: it is genuinely desirable and modern while sitting in insurance groups that are competitive with budget city cars. MoneySuperMarket’s 2026 data put its average premium at £417.64 — lower than many petrol superminis. At around £23,000 from, with 100 kW DC charging and around 200 miles real-world range, the R5 serves the mainstream market at budget-EV insurance costs.

The R5’s success in the insurance tables reflects its moderate list price, well-established Renault repair network, and sensible power output (150 hp in most UK variants).

What about the Volkswagen ID.3?

The ID.3 sits in groups 18 to 25 depending on trim and power variant. The 170 hp Standard Range (58 kWh) version is group 18 — the same as Fiat 500e — making it one of the more affordable-to-insure mid-size EVs. Average premiums are around £478 to £580 per year. Given the ID.3’s range (around 250 miles real-world), charging capability (130 kW DC), and build quality, it offers strong value for insurance-conscious buyers who need more than a city car.

Why are Tesla premiums high?

Tesla vehicles attract higher premiums for several structural reasons:

• High list prices mean high replacement values
• Tesla’s proprietary repair network of approved body shops is smaller than mainstream manufacturer networks, slowing repair timescales and increasing costs
• Some older Tesla models have required high-cost battery assessments after even minor underbody impacts
• Performance variants carry high power outputs, increasing group ratings further

The Tesla Model 3 Standard Range insures at groups 32 to 38 — higher than comparable European EVs like the VW ID.3 or Kia EV6. The insurance premium difference between a Tesla Model 3 and a Renault R5 can exceed £300 per year for the same driver profile.

How to reduce EV insurance premiums

Choose a lower-grouped model: The single most effective move. Moving from a Model 3 to an ID.3 or R5 can save hundreds per year.

Increase voluntary excess: Raising from £250 to £500 typically reduces premiums by 10 to 15%.

Pay annually: Monthly payments include a credit charge of 10 to 15% — paying annually saves money.

Garage or private driveway: Insurers apply location risk to overnight parking. A garage or driveway beats street parking significantly.

Telematics policy: If you are a careful driver, a black-box policy demonstrates this and can unlock lower premiums, particularly for younger drivers or those with limited EV claim history.

Get multiple quotes: Price comparison sites do not always include specialist EV insurers (Zego, Bikmo) or manufacturer-backed products. Check directly.

Name fewer additional drivers: Each additional driver adds risk. Only name drivers who regularly use the vehicle.

Is EV insurance getting cheaper over time?

Yes. The average gap between EV and petrol insurance premiums has narrowed from around 25% in 2024 to 10 to 15% in 2026. The trend should continue as:

• More EV-certified body shops open across the UK
• Insurers accumulate better claims data and can price more accurately
• Parts supply chains for mainstream EVs improve
• Battery technology makes replacement less catastrophically expensive

The models at the bottom of the insurance table (Dacia Spring, Renault R5, BYD Dolphin Surf) already insure at petrol-competitive rates. By 2028 to 2030, the average premium gap should be negligible for mainstream models.
