How do car insurance groups work?

There are 50 car insurance groups, and insurers place cars into one of these groups depending on their size, value, and the cost of repairs. The insurance group of a particular car represents how much a risk that kind of car might be. Cars in lower groups, such as 1-10, are more likely to be affordable, less powerful cars. Cars in the higher-up groups are usually expensive cars with bigger engines.

Other factors include:

  • The estimated cost of repairs
  • The value of the car
  • What standard safety and security features the car has

Generally, the lower the car group, the lower the cost of your insurance.

How do insurance companies decide groups?

The Group Rating Panel decides which group a car goes in. The panel is made up of members of the Association of British Insurers (ABI), Lloyds Market Association (LMA) and supported by the motor insurance research centre, Thatcham.

The Group Rating Panel considers the following when giving a car model an insurance group:

  • New car value acts as a guide to how much your car might cost to replace or repair. The more it costs, the higher the group.
  • Repair costs - including labour costs - are calculated to see how much it costs to get your car fixed and back to normal.
  • Safety features like autonomous emergency braking (AEB) lower the risk of an accident. The lower this risk, the lower the group.
  • Car bumper compatibility is assessed against the rating panel’s criteria. If the structure meets what they look for, the car goes into a lower group.
  • Performance, looking at 0-60 mph acceleration time and top speed. Typically, the more powerful the car, the higher the group.
  • Average repair time - longer repair times mean increased labour costs, which means more expensive insurance policies.
  • Security features such as alarms and immobilisers show your car is less likely to be stolen, so should fall into a lower group.

What insurance group are electric cars in?

Electric cars are sorted in the same way as petrol and diesel cars, grouped 1-50.

Insurers still view popular electric cars as being specialist. They’re typically placed in the highest insurance groups as they’re expensive to repair after a crash. And as they aren’t that common, replacement parts can be difficult to find.

For example, a Nissan Leaf sits in insurance groups 21-25, and a Kia Niro SUV is in 20-24. The Tesla Model 3, however, is in insurance groups 48-50.

What else is used when calculating car insurance?

Here are some other important factors that impact how much you pay for your car insurance:

  • Age is a major consideration for car insurance prices. Younger drivers are seen as less experienced so are more likely to be involved in a road accident. Car insurance costs are usually higher for drivers under 25.
  • Driving history and any record of previous claims or driving convictions are likely to increase your price.
  • Occupation plays an important part - if your job is in an industry deemed risky, you’re likely to see higher costs.
  • Location. If you live in a postcode with a higher crime rate, there's a great risk of you making a claim and your prices being higher.
  • The type of cover you choose. Despite comprehensive insurance offering the most cover, it’s often the cheapest.

How can I cut the costs?

There are several ways you can cut costs:

  • Increase your voluntary excess
  • Pay annually if you can
  • Get a telematics box or black box policy
  • Be accurate with your annual mileage
  • Pick the correct job title
  • Think about how you use your car, and update your class of use
  • Add car security features
  • Build up a no-claims bonus (NCB)

What our car insurance expert says

"Learning about what group your car or a car you're thinking of buying is in could help save you money on your insurance. By choosing a car in a lower group, you're more likely to be seen as a lower risk by insurers, which could lower your insurance costs."
