What insurance group is my car?

While common sense tells us it costs less to insure a Fiesta than a Ferrari, car insurance groups can be a difficult thing to wrap your head around. Use our car insurance group checker to find out which insurance group any car is in.

Find a car's insurance group

Cars are allocated a group from 1–50, with 1 typically being the cheapest to insure and 50 typically being the highest. The group ratings are based on a number of factors, including the car's value, repair costs and performance.

Car insurance groups – how the different insurance groups work

Every car on the market belongs to one of 50 car insurance groups set by the Group Rating Panel (members of the Association of British Insurers and the Lloyds Market Association). Insurers can also use their own grouping system if they want.

Typically, the lower a car’s insurance group number (1-50) the cheaper it will be to insure – for example, group 1 insurance cars are far more likely to be the cheapest cars to insure.

What factors are considered?

When the panel decides on how to assign cars to the different car insurance groups they consider the following:

Repair costs
The cost of vehicle repairs accounts for a huge chunk of the money paid out in car insurance claims. Logically then, the cost to repair the vehicle is considered before being assigned to a car insurance group.

The time it would take to repair the car is also considered as this would lead to higher repair costs.

Cost of the parts
The cost of 23 of the most common car parts is also considered. The lower the cost of the parts, the lower the car insurance group will be. To get the best car insurance quotes the cost of the parts will need to be relatively low.

The value of the car
The value of the car as new is used as an indication of how much the car will cost the insurer to repair or replace.

Performance of the car
The statistics clearly show that high performance cars that can reach great speeds are the most likely to make insurance claims. Consider the acceleration and top speeds of a car if cheap car insurance is a priority. Read our guide on insuring high performance cars to learn more.

Car security
The cheapest cars to insure will often be ones that have built-in security features by the manufacturer such as alarms, high-security locks, or immobilisers which prevent the car from being hotwired.

The security rating of a car is denoted by letters ranging from E, A, P, D down to U. The E category stands for ‘exceeds’ and the U is for ‘unacceptable’. Cars in the lower and cheaper car insurance groups will likely have an E or A security rating.
