The cheapest cars to insure for new drivers in the UK in 2026

For a 17–21 year old driver passing their test in 2026, insurance is almost always the biggest single cost of motoring — and for a significant number of first-year drivers, the annual insurance premium exceeds the purchase price of the car itself. Industry data in 2026 shows average premiums for drivers aged 17–19 sit between £1,800 and £3,000 per year for comprehensive cover, with individual quotes varying considerably depending on the car, postcode, and whether the policy includes a telematics (black box) element.

The single most effective action a new driver can take to reduce this cost is to choose a car that sits in a low insurance group. Insurance group is built into the vehicle at manufacture based on its engine power, cost of repair, safety rating, and theft profile — it cannot be changed after purchase. Getting this one decision right can be the difference between £900 and £2,600 a year in insurance costs.

This guide ranks the cheapest used cars for new drivers to insure in 2026, explains how insurance groups work under the new system, and covers the proven tactics to reduce your premium beyond just choosing the right car.

How insurance groups work in 2026

All cars in the UK are allocated an insurance group rating that helps insurers calculate premiums. A lower group number means a cheaper car to insure.

There are currently two systems in use. Cars registered before August 2024 use the traditional 1–50 scale, where group 1 is cheapest and group 50 is most expensive. Cars registered from August 2024 onwards use a new Vehicle Risk Rating system on a 1–99 scale, introduced by Thatcham Research and the Association of British Insurers to add more granularity. During an 18-month transition period — currently still in effect through most of 2026 — insurers use both systems interchangeably.

For used car buyers, the practical reality is that almost every car you will be looking at is registered before August 2024 and uses the familiar 1–50 scale. The key ranges to know are: groups 1–5 are the cheapest, typically city cars and small hatchbacks with 1.0-litre engines; groups 6–15 are still affordable for new drivers, typically larger superminis and some small SUVs; groups 16–25 start to become significantly more expensive for drivers under 25; groups 26–50 are generally unaffordable to insure as a new driver regardless of telematics discounts.

The difference in premium between a group 1 car and a group 20 car for a 19-year-old can be £1,000–£2,000 per year. Over the three years it typically takes a young driver to build meaningful no-claims bonus and move out of the highest-risk age bracket, this represents a saving that often exceeds the total purchase price of the car.

What factors determine insurance group?

The insurance group a car is placed in is decided by a panel of safety and security experts at Thatcham Research and the ABI. The main factors are:

Engine power and performance: Cars with 1.0-litre three-cylinder engines producing 60–80 hp sit in the lowest groups. Any turbocharging typically pushes a car two or three groups higher than the naturally aspirated version. Performance variants (GTI, ST, R-Line, and equivalents) consistently sit in much higher groups and should be avoided by new drivers.

Cost of repair: Cars with cheap, widely available parts are placed in lower groups. Mass-market brands with large UK dealer networks — Hyundai, Kia, Toyota, Ford, Vauxhall, Volkswagen — consistently out-perform premium brands on this measure.

Safety rating: A strong Euro NCAP score reduces the group rating, because fewer injuries mean lower claim costs. This is why modern cars with comprehensive active safety systems (autonomous emergency braking, lane keep assist) often sit in lower groups than their predecessors.

Security: Factory-fitted alarm and immobiliser systems with Thatcham Category 1 or 2 approval reduce the rating. Almost all cars from 2015 onwards qualify.

Cost of write-off replacement: More expensive cars to replace sit in higher groups. This is why a premium small car can still land in a higher group than a more basic mainstream equivalent.

The cheapest used cars to insure for new drivers in 2026

1. Hyundai i10 — insurance group 1–4

The Hyundai i10 is the single most consistently recommended car for new and young drivers based on insurance group data. The base 1.0-litre 63 hp petrol variant with the automated manual gearbox sits in group 1 — the lowest possible. Manual versions sit in group 2, and higher-trim variants with the 1.2-litre engine sit in groups 3–4. All variants benefit from a five-star Euro NCAP rating and Hyundai’s five-year unlimited-mileage warranty, which transfers to subsequent owners within the warranty period.

What the i10 lacks in outright performance — 0–62 mph in around 14 seconds with the 1.2-litre engine — it makes up for in surprising interior space, good standard equipment (many variants include Apple CarPlay, Android Auto, and a rear-view camera), and genuinely low running costs. Fuel economy of 50–55 mpg is realistic in everyday driving.

At Carsa: used i10s currently start from around £5,800 for older group 2–3 examples and run to around £15,700 for higher-spec newer cars. Best variant for cheapest insurance: 1.0-litre SE in group 1–2.

2. Kia Picanto — insurance group 2–5

The Picanto is effectively the Hyundai i10’s sister car — both brands are owned by Hyundai Motor Group and share engineering under the skin. The entry-level 1.0-litre 66 hp petrol Picanto sits in group 2, with most higher trims in groups 3–5. Kia’s seven-year 100,000-mile warranty is unusually long and transfers to subsequent owners within that window, which is a genuine ownership advantage on a used example.

The latest Picanto has notably sharper styling than the i10 and is slightly more engaging to drive, though both deliver similar real-world running costs. The three-star Euro NCAP rating on recent Picantos is lower than some rivals and worth noting if safety is a primary priority.

At Carsa: used Picantos currently start from around £5,900 for entry-spec group 2–3 cars and run to around £13,100. Best variant for cheapest insurance: 1.0-litre ‘2’ trim in group 2–3.

3. Volkswagen Polo — insurance group 3–10

The Polo is the most grown-up small car on this list — larger than a typical city car, with a notably higher-quality interior, better motorway refinement, and more presence on the road. Entry-level 1.0-litre 80 hp ‘Life’ trim variants sit in group 3, with more common 1.0 TSI turbo variants in groups 8–12. The Polo’s five-star Euro NCAP rating is excellent and active safety equipment is comprehensive on later cars.

For new drivers who will be spending time on dual carriageways or motorways, the Polo is a notably more capable and refined choice than a pure city car. The trade-off is that the truly group 3 variants are rarer on the used market — most Polos at any given time are the group 8–10 TSI variants, which are still affordable but not at the very bottom of the range.

At Carsa: used Polos currently start from around £8,100 and run to around £17,600 for the highest-spec variants. Best variant for cheapest insurance: 1.0 MPI 80 hp ‘Life’ in group 3.

4. Skoda Fabia — insurance group 4–11

The Fabia shares its underpinnings and engines with the Polo but is meaningfully cheaper to buy on the used market. Entry-level 1.0 MPI variants sit in group 4, with turbocharged 1.0 TSI variants in groups 9–13. Interior space is genuinely impressive for the segment — the boot is one of the largest in the class, and rear legroom is class-leading.

The Fabia’s five-star Euro NCAP rating is strong, though its occupant protection scored fractionally below the Polo, which likely explains why its cheapest variants sit in group 4 rather than group 3. In practical ownership terms this difference is small — typically £50–100 per year for a young driver.

At Carsa: used Fabias currently start from around £8,150. Best variant for cheapest insurance: 1.0 MPI SE Edition in group 4.

5. Toyota Aygo / Aygo X — insurance group 5–9

The Toyota Aygo and its crossover-styled successor the Aygo X sit in groups 5–9 depending on trim. Both use a 1.0-litre naturally aspirated three-cylinder engine, and both benefit from Toyota’s reputation for exceptional reliability — Aygos regularly cover 100,000+ miles with minimal major work. Servicing costs are low and parts are widely available.

The Aygo X has a slightly raised driving position that many younger drivers prefer, while remaining as small on the outside as the standard Aygo. Both models are comfortable city cars but noticeably less capable than a Polo or Fabia on motorways.

At Carsa: used Aygos from around £7,700; Aygo X from £10,600. Best variant for cheapest insurance: base Aygo in group 7–9.

6. Fiat 500 — insurance group 8–10

The Fiat 500 in its petrol form (not the 500e electric) sits in groups 8–10 for a standard 1.2-litre variant. It is the most characterful car on this list and one of the most desirable to a certain type of first-time buyer, which is part of what keeps residual values relatively strong. Insurance groups are marginally higher than the i10 or Picanto, but the purchase price on the used market is often significantly lower for equivalent age.

What to know: parts availability is good but labour costs for some jobs are higher than for Korean equivalents because access is more awkward. Fuel economy is genuinely good at around 50–55 mpg.

At Carsa: used Fiat 500s from around £5,300. Best variant for cheapest insurance: 1.2 Lounge in group 8.

7. Ford Fiesta — insurance group 10–17 (entry variants)

The Fiesta was discontinued in 2023 but remains one of the most popular used cars for young drivers in the UK. Basic 1.1-litre and 1.0 EcoBoost 85 hp variants sit in groups 10–13, with higher-powered and ST-Line variants pushing into groups 15–17. The Fiesta is more enjoyable to drive than almost every other car on this list, handles well, and has exceptional parts availability throughout the UK.

For new drivers, insurance group matters — a Fiesta in group 13–15 will cost meaningfully more to insure than an i10 in group 2, often £300–£600 more per year for a 19-year-old. If the driving experience matters to you, this premium may be worth it. If pure insurance cost is the priority, the Korean city cars above remain the stronger recommendation.

At Carsa: used Fiestas currently start from around £8,100 and run to around £14,900 for higher-spec variants. Best variant for cheapest insurance: 1.1 Trend in group 10.

8. SEAT Ibiza — insurance group 3–15

The SEAT Ibiza shares its platform with the Polo and Fabia, and pricing on the used market typically sits between the two. The base 1.0 MPI 80 hp variants sit in group 3, though most Ibizas currently available used are the 1.0 TSI variants in groups 11–13 which remain competitive but are meaningfully higher than the entry-level Polo or i10. The five-star Euro NCAP rating is excellent.

The Ibiza feels fractionally more youthful than the Polo in terms of styling and driving dynamics, though in every practical measurement the two cars are very similar.

At Carsa: used Ibizas currently start from around £8,200 and run to around £16,400. Best variant for cheapest insurance: 1.0 MPI SE in group 3–4.

9. Toyota Yaris — insurance group 8–14

The Yaris — particularly the hybrid variant — is the most fuel-efficient car on this list by a significant margin. The petrol 1.5 Hybrid typically returns 60–70 mpg in real-world driving and sits in groups 13–14, while older petrol-only Yarises sit in groups 8–10. Toyota’s reliability record on the Yaris is exceptional.

The Yaris Hybrid is a notably more accomplished car than the i10 or Picanto — more refined, more comfortable, more capable on longer journeys. For a new driver who is likely to cover significant motorway mileage rather than purely urban use, the extra insurance group cost may be outweighed by the fuel savings.

At Carsa: used Yarises from around £9,100. Best variant for cheapest insurance: older 1.0 VVT-i in group 8.

How to reduce your premium beyond just picking the right car

Choosing a low-group car is the largest single factor, but there are several other steps that reduce premiums meaningfully for new drivers.

Consider a telematics (black box) policy. Telematics insurance monitors your driving through an app or small device fitted to the car, tracking speed, braking, cornering, and time of day driven. For young drivers who drive carefully and avoid high-risk times (late-night weekend driving especially), discounts of 20–40% on the base premium are common. The privacy trade-off is real but for most new drivers the financial case is overwhelming.

Add an experienced named driver. Adding a parent or older sibling with a clean licence as a named driver typically reduces the premium because insurers view the risk pool as lower. This is only legitimate if that person genuinely drives the car occasionally — declaring a named driver as the main driver when they aren’t is called ‘fronting’ and is insurance fraud.

Build your no-claims bonus. Even a single year of no-claims discount reduces your renewal premium significantly. Keeping an unblemished driving record for the first year is the single most valuable thing a new driver can do for future premiums.

Park securely. Insurers ask where the car is kept overnight. Cars parked in a garage or on a private driveway attract lower premiums than cars parked on the street. If you have the option of either, use it.

Increase your voluntary excess — carefully. Agreeing to pay a higher first amount toward any claim reduces the annual premium. Choose an excess level you could genuinely afford to pay if you needed to claim — the saving is meaningful but so is the downside if the excess is unrealistic.

Pay annually if you can. Monthly payments are effectively a loan from the insurer and typically add 10–15% to the total cost over the year in interest charges. If you can afford to pay the full premium upfront, the saving is substantial.

Shop around on every renewal. Insurers rarely offer loyal customers their best rates. Getting quotes from multiple providers at renewal — or using comparison sites — typically reduces the renewal premium by 10–30%.

What to avoid as a new driver

Several categories of car are consistently expensive to insure for young drivers regardless of telematics discounts or no-claims bonus. Performance variants — Fiesta ST, Polo GTI, Corsa VXR, Clio RS, 1 Series M Sport — sit in high groups and attract premiums that often exceed £4,000 per year for drivers under 25. Modified cars (aftermarket exhausts, lowered suspension, body kits) increase premiums substantially and must be declared. Older premium-badged cars (older BMW 3 Series, Audi A3, Mercedes C-Class) may look affordable to buy but commonly sit in insurance groups 20–30+, which for a 19-year-old can mean £3,000–£4,000 per year in premiums — far more than any fuel or running cost advantage they offer.

Electric cars are worth noting separately. While EVs are cheaper to run, insurance groups for EVs are consistently higher than equivalent petrol cars — typically groups 15–25 even on compact models — because of battery replacement costs and specialist repair requirements. For new drivers prioritising minimum insurance cost, a petrol city car in groups 1–5 remains the strongest choice in 2026.
