How are car insurance groups decided?
Insurance grouping is decided by the group rating panel, made up of members of the Association of British Insurers and the Lloyds Market Association and supported by Thatcham Research. The panel decides which insurance group new car models fall into based on the following factors:
- New car values: The price of a new car and its specifications are a guide to potential replacement and repair costs
- Parts and repair: The likely extent of damage to each model and the price of the parts involved also indicate repair costs, and lower costs usually mean a lower group rating
- Parts prices: A list of 23 common parts is used to compare one manufacturer’s parts costs to another
- Repair times: Long repair times mean higher costs and a higher group rating. According to Thatcham Research, over half of all money paid out in motor insurance claims goes on repairing cars – so the cost of spare parts and repair times are major factors in pricing motor insurance
- Performance: High-performance cars are at higher risk of frequent insurance claims, so acceleration and top speed are taken into account
- Safety: Vehicles fitted with AEB (autonomous emergency braking) systems are more likely to avoid low-speed front-to-rear accidents and could make for a lower insurance group rating
- Bumper compatibility: The alignment and structure of bumpers is a factor
- Car security: Cars with security features, such as alarm or immobilisation systems and high-security door locks, could enjoy a lower insurance group. But if you lose a key or fob it will be more expensive to replace.

What insurance group do electric cars fall into?
Electric cars, like any other cars, are sorted into insurance groups as a way of categorising the overall risk it would present to an insurer. These groups are numbered from one to 50, with the lowest being the cheapest to insure.
However at the moment electric cars are still viewed as somewhat specialist vehicles – they aren’t especially common, though their numbers on the road are rising. This means conducting repairs or finding replacement parts can be more difficult than it would be with a standard fuel-powered car.
As a result, you may find that electric cars aren’t often found in the lowest insurance groups – compared with petrol and diesel vehicles in their class and size, they’ll normally be more expensive to cover.
How is car insurance calculated?
Car insurance providers set your premiums based on the overall claim risk you represent to them, which is calculated by taking a range of factors into account. As well as the car you drive – and subsequently the insurance group it’s in – they also take the following into account:
- Age: Your age is a major factor as it’s generally held that young drivers are more likely to be involved in a road accident owing to their inexperience on the road. The good news is once you turn 25, your premiums will usually fall
- Driving history: Being inexperienced on the road is one thing, but having a record of previous claims or driving convictions are also likely to count against you
- Location: Some areas in the UK see higher levels of theft or vandalism than others, so if you live in a postcode with high crime you might find this reflected in higher premiums
- Occupation: Certain industries and occupations also carry higher risk factors, so your premiums can also be affected by the job you have
How can I cut the cost of car insurance?
Buying a vehicle in one of the lower insurance groups is one of the best ways to cut the cost of your policy. However, if your car is in a higher group and you want to reduce your premiums, there are several ways to get a cheaper insurance quote:
- Car security and storage: Enhancing your car’s security features can reduce the chances of theft, as will keeping your car in a locked garage, so you’ll see lower premiums
- Excess: This is what you pay towards a claim before your insurer covers the rest. You might be able to volunteer for a higher excess, which will drive your premiums down
- Named drivers: Adding a named driver with lots of driving experience and few motor insurance claims can also reduce the cost of cover
- Pay annually: Often insurers will give discounts to your premiums if you pay annually instead of monthly
- No-claims bonus: Insurers may also reduce the cost of your policy if you haven’t made a previous insurance claim in a while – the longer the better
- Drive less: You may be asked to give an approximate mileage for a quote, and if you drive less in a year, it reduces the chances of you being involved in an incident and needing to claim
- Telematics: Telematics, or black box insurance, is when your insurer monitors your driving habits, and the better you drive the lower your premiums can be
- Pay-as-you-go: There are increasing numbers of pay-as-you-go policies on the market. They generally involve a fixed monthly premium to cover your car while it’s parked, after which you only pay for how much you drive – usually by the mile
