Car Insurance Group 20: Cars and Cost (UK 2026)
A group 20 car typically costs a mid-range UK driver around £600 to £800 a year for comprehensive cover in 2026 — think family hatchbacks and small SUVs like the Ford Focus, VW Golf and Nissan Leaf.
What car insurance group 20 means
Every car sold in the UK is placed in an insurance group from 1 to 50, where group 1 is the cheapest to insure and group 50 the most expensive. Group 20 sits squarely in the affordable middle of that scale — the territory of practical family hatchbacks, mid-size estates and small SUVs. It is not a "cheap" group in the way that groups 1 to 5 are, but it is a long way from the high-performance and premium models that fill groups 40 and above.
The groups are set by Thatcham Research and a panel from the Association of British Insurers (ABI). They weigh five main factors: the cost of parts, how long repairs take, the car's performance, its new and used value, and its security features. A group 20 rating signals a car that is moderately expensive to repair and reasonably powerful, but still mainstream and well protected.
Cars registered from August 2024 are also being assigned a new Vehicle Risk Rating (VRR) on a 1 to 99 scale, which insurers are adopting alongside the familiar 1 to 50 groups. For the millions of used cars on UK roads, the 1 to 50 group system remains the number most drivers will see when they get a quote.
Indicative group 20 premium by driver age
The table below shows indicative annual comprehensive premiums for a typical group 20 car in 2026, broken down by driver age band. These are illustrative ranges built from published UK market averages — your own quote depends far more on your age, postcode, mileage and claims history than on the group number alone.
| Driver age band | Indicative annual premium (comprehensive) | Notes |
|---|---|---|
| 17–24 | £1,300 – £2,000 | Youngest drivers pay the most; a black box policy can cut this sharply |
| 25–34 | £700 – £950 | Premiums fall steadily as experience and no-claims build |
| 35–64 | £550 – £750 | The cheapest band; close to the UK average of about £600 |
| 65+ | £600 – £850 | Costs edge up again in later years but stay affordable |

Cars often rated around group 20
Because the same model can span many groups depending on engine, trim and safety spec, no car is "always" group 20. A base petrol hatchback might sit in group 8 while its sportier sibling lands in the low 20s. That said, cars often rated around group 20 include:
- Ford Focus (ST-Line, 1.0 EcoBoost mHEV) — the popular family hatchback; sportier and mild-hybrid trims push it into the low 20s.
- Volkswagen Golf / Golf SV — higher-spec diesel and SV variants commonly fall in or near group 20.
- Nissan Leaf (Acenta) — a mainstream electric hatchback whose battery and repair costs place it around group 20.
- Ford Kuga (TDCi diesel) — a compact SUV that sits around group 20 in diesel form.
- Mazda CX-5 (SE-L) — a mid-size SUV frequently rated in the group 20 region.
- Volkswagen Golf SV / Toyota Prius+ — roomy MPV-style variants that land close to group 20.

How to pay less in group 20
- Increase your voluntary excess — agreeing to pay more towards a claim usually lowers the premium, as long as you can afford the excess.
- Build and protect your no-claims discount — several years of no claims is one of the biggest levers on price.
- Pay annually rather than monthly — monthly instalments add interest, often 20% or more over the year.
- Add a named experienced driver — a low-risk second driver can reduce the price (but never "front" a policy, which is illegal).
- Consider telematics (a black box) — especially valuable for 17–24 drivers, where it can cut hundreds off a group 20 quote.
- Improve security and reduce mileage — a garage, a tracker and a lower annual mileage estimate all help.
- Compare widely and switch at renewal — loyalty rarely pays; shop around 3–4 weeks before renewal for the best price.
Group 20 car insurance: common questions
Group 20 is affordable but not the cheapest. It sits in the middle of the 1 to 50 scale, so it costs more to insure than a group 1 to 10 city car, but far less than a high-performance car in group 40 or above. For a typical mid-range driver, a group 20 car costs roughly £600 to £800 a year for comprehensive cover in 2026.
The group is only one input. Your age, postcode, driving history, annual mileage, job, no-claims discount, chosen excess and how you pay all move the price — usually more than the group number itself. A 19-year-old and a 45-year-old in the same group 20 car can pay wildly different premiums.
Check the exact engine and trim, not just the model name, because variants span different groups. You can look up any car with our car insurance by vehicle tool, or use a free group checker from Thatcham, Confused.com or MoneySuperMarket. The vehicle's V5C logbook and manufacturer spec sheet also help identify the precise variant.
Yes. Choosing a lower-powered engine or a lower trim of the same model can drop you into the mid-teens or lower. If cheap insurance is the priority, look at cars in groups 1 to 10 — small city cars and superminis — or compare the adjacent group 19 and group 21 to see how much a single group shifts the price.
No. The group tells insurers how risky and costly the car is to repair and replace, but it is just one factor in a wider calculation. Two drivers in the same group 20 car can be quoted hundreds of pounds apart because of age, location, claims history and mileage. Treat the group as a guide, not a guarantee of price.
The traditional system rates cars from 1 to 50 and still applies to most cars on UK roads. For cars registered from August 2024, Thatcham introduced the Vehicle Risk Rating (VRR) on a wider 1 to 99 scale, giving insurers finer detail on modern safety and repair technology. Both systems aim to reflect the same thing: how much a car is likely to cost to insure.
