Car Insurance Group Checker
Every car sold in the UK is assigned to one of 50 insurance groups by the Group Rating Panel, which includes members from the ABI and Thatcham Research. Group 1 is cheapest to insure and Group 50 the most expensive. Understanding where your car sits on this scale is one of the most effective ways to manage your insurance costs.
What determines your car's insurance group?
The Group Rating Panel, administered by Thatcham Research on behalf of the ABI, assesses every new car model and assigns it to a group based on several factors:
- Repair costs — How much it costs to fix the car after an accident, including parts prices, paint and labour times. Cars with expensive parts or complex body panels score higher.
- Performance — Engine size, power output, acceleration and top speed. Faster cars are statistically more likely to be involved in higher-speed accidents.
- Safety features — Cars with good Euro NCAP ratings, autonomous emergency braking and advanced driver assistance systems may be placed in lower groups.
- Vehicle security — Factory-fitted security features including immobilisers, alarm systems and tracking devices. Thatcham rates security on a scale.
- New car value — The list price of the car affects replacement cost in the event of a total loss.
- Bumper compatibility — How well the car's bumpers absorb low-speed impacts. Better absorption means lower repair bills.
You can check the insurance group of any car by searching the Thatcham Research database or entering the registration number on most comparison sites. If you are buying a new car, checking the insurance group before purchase could save you hundreds of pounds per year on premiums.
Watch out for these car insurance pitfalls
Car insurance is full of traps that can cost you money or even invalidate your cover. The FCA receives thousands of complaints about motor insurance each year. Here are the most common issues to be aware of.
Fronting is fraud
Fronting occurs when a parent or older driver is listed as the main driver on a policy for a car primarily used by a younger person. It is a form of insurance fraud, even if well-intentioned. If an insurer detects fronting (and they use data analytics to spot it), the policy will be voided, claims refused, and the young driver may be left unable to obtain cover. According to the ABI, insurers detect around 350,000 fraudulent claims per year, and fronting is one of the most common forms.
Undeclared modifications
Any modification to your vehicle — even cosmetic changes like alloy wheels, tinted windows or a sports exhaust — must be declared to your insurer. Failing to declare modifications can void your policy entirely. Under the Consumer Insurance (Disclosure and Representations) Act 2012, you have a duty to answer all questions honestly. Insurers have the right to refuse claims and cancel cover if they discover undeclared changes. This applies equally to performance mods and visual changes.
Auto-renewal loyalty penalty
While the FCA's 2022 pricing rules stopped insurers charging existing customers more than new ones, auto-renewal still poses risks. Insurers set their renewal price based on their own pricing model, which may not be the cheapest available from across the market. According to MoneySavingExpert, simply accepting a renewal quote without comparing means you are likely missing cheaper alternatives. Set a calendar reminder 21 days before your renewal date and compare every year.
Comprehensive is often cheaper than third party
It sounds counterintuitive, but comprehensive cover is frequently cheaper than third-party only. The reason: insurers view drivers who choose third-party only as higher risk (statistically, they are more likely to be younger, less experienced or have adverse claims history). The ABI data consistently shows that comprehensive premiums are lower on average. Always compare all three cover levels before assuming third-party only will be cheapest.
Driving Other Cars (DOC) cover
Many drivers assume their policy allows them to drive other people's cars. In reality, most modern policies no longer include Driving Other Cars (DOC) cover as standard. Even where DOC is included, it only provides third-party cover — meaning you would not be covered for damage to the car you are driving. The RAC Foundation reports that many drivers discover this only after an incident. Always check your policy schedule for specific DOC wording before driving someone else's vehicle.
Telematics: what they actually collect
Black box and telematics policies monitor more than just your speed. They typically record acceleration patterns, braking harshness, cornering forces, time of day, journey length, road type and total mileage. Some also track phone usage while driving. This data is used to calculate your driving score and can affect your renewal premium. Consistently poor scores can lead to premium increases or even policy cancellation. The data is also retained by the insurer and may be shared with third parties under certain circumstances, as outlined in their privacy policy.
Average car insurance premium by age
Age remains the single biggest factor in car insurance pricing. This chart shows the average annual premium for each age band across UK drivers. Data sourced from ABI and MoneySavingExpert analysis, 2025.
The dramatic difference between age groups reflects the statistical risk that insurers measure. Drivers aged 17–20 face the highest premiums because they are, according to Department for Transport data, significantly more likely to be involved in accidents. Premiums fall sharply through the twenties as drivers gain experience and build a no-claims record. The cheapest band is typically 51–65, after which premiums rise slightly as some insurers apply age-related loadings and medical factors begin to play a role.
Average premiums by age group
Premiums vary dramatically depending on your age and driving experience. Data sourced from ABI and MoneySavingExpert analysis, 2025.
| Age Group | Average Annual Premium | Key Factors |
|---|---|---|
| 17–19 | £2,400 | No driving experience, highest accident risk, limited choice of vehicles |
| 20–24 | £1,450 | Some experience, telematics can help, still statistically high-risk |
| 25–29 | £870 | Premiums begin to fall, building no-claims bonus, broader insurer options |
| 30–49 | £620 | Statistically lowest risk bracket, maximum no-claims discount available |
| 50–64 | £480 | Typically cheapest age band, strong driving records, lower mileage |
| 65+ | £540 | Slight increase, some insurers add age loadings, medical declarations |
Factors that affect your car insurance premium
Your vehicle
Cars are assigned to one of 50 insurance groups. Higher groups (sporty, powerful or expensive cars) cost more to insure. Choosing a vehicle in groups 1–10 can reduce your premium significantly.
Where you live
Postcode is one of the biggest rating factors. Urban areas with higher traffic density and theft rates attract higher premiums than rural locations. The FCA reports up to 40% variation by postcode.
No-claims bonus
Each claim-free year earns you a no-claims discount (NCD). After five years you could save up to 65% off the base premium. Protecting your NCD costs extra but prevents losing your discount.
Voluntary excess
Increasing your voluntary excess from £100 to £500 can reduce your annual premium by 10–15%. However, you must be confident you can afford the excess if you need to claim.

The average UK car insurance premium is around £924 per year (ABI, 2025). However, costs vary significantly by age, location, vehicle type and driving history. Drivers aged 17–24 pay the most, averaging £1,800–£2,400 per year, while drivers over 50 typically pay £400–£600.
The three levels of car insurance in the UK are: Third Party Only (the legal minimum, covers damage to other people and their property), Third Party Fire and Theft (adds cover for your car if stolen or damaged by fire), and Comprehensive (covers all of the above plus damage to your own vehicle, even if the accident is your fault).
You can reduce your premium by increasing your voluntary excess, building up no-claims bonus, adding a named driver with experience, choosing a car in a lower insurance group, reducing your annual mileage, improving vehicle security, and comparing quotes from multiple insurers at least 21 days before renewal. Read our full guide to reducing car insurance.
Research from MoneySavingExpert and the ABI suggests that comparing car insurance around 21 days before your renewal date typically yields the cheapest quotes. Avoid leaving it to the last minute, as prices tend to increase closer to the renewal deadline.
No. Under the Road Traffic Act 1988, it is illegal to drive or keep a vehicle on a public road without at least Third Party insurance. Penalties include a fixed penalty of £300 and six points on your licence, or an unlimited fine and disqualification if the case goes to court. Your vehicle may also be seized and destroyed.
Insurance group 1 is the cheapest. Cars in this group include the Volkswagen up!, Hyundai i10 and Toyota Aygo. Groups are determined by the Group Rating Panel using factors including repair costs, performance, safety features and security ratings. Choosing a car in groups 1–10 can significantly reduce your premium — the difference between group 1 and group 30 can be several hundred pounds per year.
Yes. Insurers use your occupation as a rating factor because certain jobs are statistically linked to higher or lower claim rates. How you describe your job matters — for example, “chef” and “kitchen manager” may produce different quotes for the same role. Always describe your job accurately, but consider which legitimate job title best fits your role. Research from MoneySavingExpert has shown that job title variations can create differences of £50–£300 per year.
Most modern car insurance policies no longer include Driving Other Cars (DOC) cover as standard. Even where DOC is included, it typically only provides third-party cover — meaning damage to the other person’s car would not be covered. Always check your policy schedule for specific DOC wording before driving someone else’s vehicle. If you need to drive another car regularly, consider temporary insurance or ask the car owner to add you as a named driver on their policy.
Driving without insurance is a criminal offence. Penalties include a fixed penalty of £300 and 6 points, or an unlimited fine and driving ban if the case goes to court. Your vehicle can be seized and destroyed by the police. You would also be personally liable for all damage and injury costs, which can run into hundreds of thousands of pounds. The Motor Insurers’ Bureau (MIB) pays compensation to victims of uninsured drivers and will pursue you for the full amount paid out.
Paying annually is almost always cheaper. Monthly payments are effectively a credit agreement, so insurers charge interest — typically 15–30% APR. Over a year, this can add £100–£200 to your total cost. If you can afford to pay the lump sum upfront, annual payment will save you money. However, some drivers prefer the flexibility of monthly payments despite the extra cost, particularly if the annual premium is high.
