Cheapest Cars to Insure in the UK (2026): Complete Guide

Key takeaway: The cheapest cars to insure in the UK sit in insurance groups 1 to 5. These cars share common traits: small engines (1.0L to 1.2L), low power output, inexpensive replacement parts, and strong safety ratings. For a new driver, choosing a Group 1 car over a Group 20 car can mean saving over £1,500 per year on insurance alone.

Car insurance is one of the largest running costs for UK drivers, especially younger or newly qualified ones. The average UK car insurance premium hit £924 in 2025 according to the ABI. For drivers under 25, that figure can easily triple. Picking the right car from the start is one of the most effective ways to keep costs under control.

In this guide, we break down how insurance groups work, list the cheapest cars to insure in each category, and share practical strategies to reduce your premium further.

How UK Insurance Groups Work

Every car sold in the UK is assigned an insurance group from 1 (cheapest) to 50 (most expensive). The group is set by the Group Rating Panel, which is run jointly by the Association of British Insurers (ABI) and Lloyds Market Association (LMA). They assess each car based on several factors:

• Damage and parts costs: How expensive is the car to repair? Cars with cheap, widely available parts score lower.
• Repair times: How long does a typical repair take? Complex designs with hard-to-reach components push groups up.
• New car value: Higher value cars cost more to replace, so they sit in higher groups.
• Performance: Top speed and 0-60 time directly affect the group. Faster cars are statistically more likely to be involved in accidents.
• Safety and security: Cars with strong Euro NCAP ratings and good security features (immobilisers, Thatcham-rated alarms) get lower groups.
• Bumper compatibility: Cars designed to absorb low-speed impacts cheaply score better.

You can check the insurance group for any specific car model on our insurance groups page, which covers all 50 groups with example cars in each.

Group 1: The Absolute Cheapest to Insure

Group 1 cars offer the lowest possible insurance premiums. They are small, low-powered, and built with cheap-to-replace parts. These are the top picks:

Volkswagen Up! 1.0 (60-65 PS)

The VW Up is one of the best city cars ever made. Its 1.0-litre three-cylinder engine returns around 55-60 mpg, road tax starts from £20/year for pre-2017 models, and parts are cheap and widely available. MOT pass rates for the Up are consistently above 85%, which is excellent for a city car. Insurance group 1 across all basic trim levels makes it one of the cheapest cars on the road to run.

Fiat Panda 1.2 (69 PS)

The Panda has been a staple of cheap motoring for decades. The 1.2-litre petrol version sits in Group 1, returns around 50 mpg, and has a loyal following that means parts are never hard to find. It is simple, practical, and costs very little to keep on the road. The interior is basic, but everything that matters mechanically is straightforward and cheap to fix.

Citroen C1 1.0 (68 PS)

The C1 shares its platform with the Toyota Aygo and Peugeot 108, which means Toyota-grade reliability with French pricing. The 1.0-litre engine is bulletproof, servicing costs are minimal, and insurance sits firmly in Group 1. This is one of the most common first cars in the UK for good reason.

Skoda Citigo 1.0 (60 PS)

Essentially a rebadged VW Up with a slightly lower price tag, the Citigo offers identical running costs and the same Group 1 insurance rating. Skoda parts pricing tends to be fractionally lower than VW, making it arguably the single cheapest car to own and insure in the UK right now.

Groups 2 to 5: Still Very Cheap to Insure

Moving up to Groups 2 through 5 opens up more choice without significantly increasing your premium. Here are standout options in each group:

Electric Cars and Insurance Groups

Electric cars present a mixed picture for insurance. On the one hand, they have fewer moving parts and lower maintenance costs. On the other, battery replacement is extremely expensive and specialist repair facilities are still relatively rare, which pushes repair costs up. The cheapest electric cars to insure include:

• Smart EQ ForTwo: Groups 8 to 12 depending on spec. The smallest EV on sale, and the cheapest to insure.
• Fiat 500e: Groups 14 to 18. More expensive than the petrol 500 to insure, but the running cost savings on fuel offset this for high-mileage drivers.
• MG4 Standard Range: Groups 18 to 22. Competitive for a full-size EV, though still significantly more than a Group 1 petrol car.
• Renault Zoe: Groups 16 to 21. One of the more affordable used EVs, but check the battery lease terms on pre-2020 models.

For most buyers focused purely on insurance cost, a petrol car in Groups 1 to 5 remains substantially cheaper to insure than any EV currently on sale.

What Affects Your Premium Beyond the Car

The insurance group is only one factor in your premium calculation. Insurers also consider:

• Your age: Drivers aged 17 to 24 pay the highest premiums. A 17-year-old in a Group 1 car might still pay £1,500+ per year. The same car for a 30-year-old with 10 years no-claims could be under £300.
• Your postcode: Urban areas, especially parts of London, Birmingham, and Manchester, have higher premiums due to theft and accident rates.
• Annual mileage: Declaring lower annual mileage (and sticking to it) reduces your premium. If you only drive 5,000 miles per year, say so.
• Where you park: A locked garage is cheapest. A private driveway is better than on-street parking.
• Voluntary excess: Increasing your voluntary excess from £0 to £300 or £500 can cut 10-20% off your premium, but make sure you can afford to pay it if you need to claim.
• Job title: Insurers use your occupation as a risk factor. Some job titles are statistically cheaper than others. "Software developer" often costs less than "student," for example.
• No-claims bonus: Every year without a claim reduces your premium. Five or more years of no-claims discount can cut your premium by 60% or more.
• Black box (telematics): For young drivers, a black box policy can reduce premiums by 20-40%. You agree to have your driving monitored, and safe driving is rewarded with lower costs. It is worth considering if you are under 25.

7 Practical Tips to Cut Your Insurance Cost

1. Compare every year. Never auto-renew. Use comparison sites (GoCompare, CompareTheMarket, Confused.com) and also check direct-only insurers like Direct Line and Aviva who do not appear on comparison sites.
2. Add a named driver. Adding an experienced, older driver to your policy as a named driver (not the main driver) can reduce your premium. This is legal and different from "fronting," where the older person is fraudulently listed as the main driver.
3. Pay annually. Monthly payments add 15-30% in interest. If you can pay the full year upfront, do it.
4. Get a dash cam. Some insurers offer discounts for dash cam users, and the footage can protect you in disputed claims.
5. Take a Pass Plus course. After passing your test, a Pass Plus course costs around £150 to £200 and some insurers offer a discount for completing it.
6. Choose the right car from the start. This is the biggest single lever. A Group 1 to 5 car versus a Group 15 to 20 car can save over £1,000 per year in insurance alone.
7. Check the car's full costs before buying. Insurance is just one piece of the puzzle. Use our free car check tool to see the complete cost picture: insurance group, road tax, fuel costs, MOT history, and predicted repair costs all in one report.

Common Myths About Car Insurance Groups

"Older cars are always cheaper to insure"

Not true. Older cars often lack modern safety features and have poorer Euro NCAP ratings, which can push insurance costs up. A 2015 car in Group 3 is usually cheaper to insure than a 2005 car in Group 12.

"Red cars cost more to insure"

This is completely false. Colour has no effect on your insurance premium. Insurers do not even ask what colour your car is.

"Modifications always increase your premium"

Performance modifications (exhaust, engine remap, suspension) almost always increase your premium. But security modifications (Thatcham-rated alarm, tracking device, immobiliser upgrade) can sometimes reduce it. Always declare modifications to avoid invalidating your policy.

The Bottom Line

If you want the cheapest possible insurance, buy a car in Groups 1 to 5 with a 1.0L or 1.2L engine. The VW Up, Citroen C1, Skoda Citigo, and Toyota Aygo are the standout choices. Combine that with smart policy choices (annual payment, named driver, black box if you are young) and you can keep your total insurance bill well below the national average.
