Car Insurance Groups

How car insurance groups affect car insurance premiums

If you're looking to save money and get a cheaper car insurance premium, it's worth thinking about how the insurance group your car is in affects your car insurance premium. Cars in lower insurance groups attract a lower premium, so it's worth understanding how insurance groups work.

Car insurance groups are set by the Group Rating Panel, which includes members of the Association of British Insurers (ABI) and Lloyds Market Association (LMA). The panel meets each month to recommend an insurance group for each new passenger car built to a UK specification. 70% of the information used by the panel in its assessment is based on research conducted by the Motor Insurance Repair Research Centre (Thatcham).

The panel assign cars to one of twenty groups. Cars in the highest groups, typically high performance models, are those which are likely to cost insurers the most in insurance claims.

Insurers may use the panel recommendations in their calculation of car insurance premiums but, as these groupings are provided as a recommendation only, they may choose to use their own groupings. Thatcham have recently introduced a new set of fifty groups, which they are using alongside the existing twenty groups in testing new cars. The move to fifty groups means that each model of car can be more accurately banded with similar cars. Some insurers are now using fifty groups in their premium calculations.

According to the ABI, the cost of motor vehicle repairs accounts for over half of all the money paid out in motor insurance claims, so it's no surprise that repair costs feature strongly in how the groups are defined.

Based on their research, Thatcham define the factors used to assess new cars as follows:

Damage and parts costs

This covers the likely extent of damage to each car model and the cost of the parts involved in its repair. The lower these costs, the more likelihood there is of a lower group rating.

Repair costs and times

Longer repair times mean higher costs and the greater likelihood of a higher group rating. Different paint finishes on modern cars are an important factor, so these are also taken into account.

New car values

The prices of new cars are taken into account, as they are often a good guide to the cost of replacement and repair.

Body shells and accident repairs

The availability of body shells (the basic frame of the car) is taken into account in group ratings because they are essential for certain accidental damage repairs.

Car performance

Acceleration and top speed are important factors. Insurers know very well, from their claims statistics, that high performance cars often result in more frequent insurance claims.

Car security

Security features fitted as standard equipment by motor manufacturers can help to reduce insurance claims costs. Such features include high security door locks, alarm / immobilisation systems, glass etching, coded audio equipment, locking devices for alloy wheels and visible Vehicle Identification Number (VIN) numbers.

How to check car insurance groups

If you want to check the insurance group for your car, or are buying a car, you can search the ABI database to find the group rating for the model you're interested in.
