What sits in groups 31–40 — and why

Performance trims of mainstream cars, executive saloons and larger SUVs occupy these groups. Power outputs, parts prices and theft appeal all step up, and insurers price accordingly — this is the tier where the car itself starts to rival the driver as the biggest factor in the premium.

Placement is not guesswork: the Group Rating Panel — administered by Thatcham Research for the ABI and Lloyd's Market Association — scores every new model on new-car value, parts prices, repair times and costs, performance, and security. Cars registered from August 2024 also carry a Vehicle Risk Rating from 1 to 99 on the same evidence. The group is the panel's summary of how expensive a car is likely to be to put right — which is why it tracks repair economics more closely than badge or size.

Groups 31–40 — common questions

Performance trims of mainstream cars, executive saloons and larger SUVs occupy these groups. Power outputs, parts prices and theft appeal all step up, and insurers price accordingly — this is the tier where the car itself starts to rival the driver as the biggest factor in the premium.

The Group Rating Panel, administered by Thatcham Research on behalf of the Association of British Insurers and Lloyd's Market Association. The panel assesses new models against standard criteria — new-car value, parts prices, repair times and costs, performance, and security — and assigns a group from 1 to 50. Insurers are free to depart from the recommendation, but in practice most use it as the starting point for pricing.

All else being equal, yes — but the driver usually matters more than the car. Age, postcode, claims history and no-claims discount move a premium far more than a few group points. A low-group car is the right lever for a young or new driver, while an experienced driver with a long no-claims history will see much smaller differences between neighbouring groups. Each group page in this band shows what its example cars typically cost across driver profiles.

The successor system to the 1–50 groups for cars first registered from August 2024: a score from 1 to 99 across five areas — performance, damageability, repairability, safety and security. Both systems will run alongside each other for years, because the existing car parc keeps its 1–50 ratings. Where a newer car carries a VRR, its page notes it.
