What car insurance group 45 means

Every mass-market car sold in the UK is placed in one of 50 insurance groups by the Group Rating Panel, run by Thatcham Research on behalf of the Association of British Insurers (ABI). Group 1 cars are the cheapest to insure; group 50 the dearest. Group 45 sits in the top band (41–50), reserved for high-performance and luxury vehicles.

A car lands in group 45 because of some combination of a high purchase value, expensive or slow-to-source parts, long repair times, strong performance and, in some cases, a higher theft risk. In practice that means fast estates and saloons, performance SUVs and premium coupes. Cars first registered from August 2024 also carry a newer 1–99 Vehicle Risk Rating, but the familiar 1–50 group still drives most quotes today.

Crucially, the group is only one rating factor. Your age, postcode, mileage, no-claims history and job usually move the premium far more than the group number alone. For context, the overall UK average comprehensive premium is roughly £600 — so a group 45 car sits well above the typical car, but a settled, older driver can still insure one for far less than a teenager pays.

Cars often rated around group 45

Insurance groups vary by exact trim, engine and model year, so a single nameplate can span several groups. The following are examples of cars whose higher-performance or higher-value trims are often rated around group 45 — always check your specific registration with a group checker.

  • Audi RS 4 Avant — the twin-turbo V6 performance estate frequently rates around group 44–45.
  • BMW M4 (and M-Sport 4 Series) — top petrol and M trims of the 4 Series span roughly groups 43–45 and above.
  • Ford Mustang 5.0 V8 GT — the V8 muscle car sits in the mid-40s on power and repair cost.
  • Mercedes-AMG C-Class / GLC — higher-output AMG and top petrol trims commonly land in the mid-40s.
  • Range Rover Sport / Porsche Macan (performance trims) — powerful, high-value SUVs often rate in the mid-to-high 40s.
  • Jaguar F-Type / F-Pace (higher trims) — V6 and performance versions frequently reach the mid-40s.

How to pay less on a group 45 car

  • Build and protect your no-claims discount — it is one of the biggest levers on a high-group premium.
  • Increase your voluntary excess — a higher excess lowers the premium, if you can afford the excess after a claim.
  • Fit and declare an approved (Thatcham-rated) tracker or alarm — security discounts matter more on theft-attractive cars.
  • Keep annual mileage honest but low — fewer miles usually means a lower quote; never under-declare.
  • Garage or off-street parking — secure overnight parking can meaningfully cut the premium.
  • Pay annually rather than monthly — monthly instalments add interest (APR).
  • Compare widely and consider a specialist or box policytelematics can help younger drivers on high-group cars.

What does group 45E, 45A or 45D mean?

The letter after “45” is the Thatcham / ABI security rating for that exact model. 45E means the car’s security exceeds what the panel expects for group 45, so it is treated as a group 44 car for security purposes — usually a slightly cheaper premium. 45A is acceptable (no change). 45D means the security doesn’t meet the standard, so it is treated as group 46. P is a provisional rating and U means unacceptable security. The full letter table is on our car insurance groups hub.

Group 45 insurance: common questions

Yes — group 45 is near the top of the 1–50 scale, so it is one of the more expensive bands. A typical mid-range driver might pay roughly £1,600–£2,500+ a year for comprehensive cover, versus a UK average of about £600. Your age, postcode and claims history still matter more than the group alone.
Thatcham Research and the ABI set groups on the car's value, the cost and availability of parts, repair times, performance (power and speed), safety features and security. High-performance, high-value cars therefore land in the top bands like group 45.
Use a free group checker (for example, Confused.com or Compare the Market) and enter your registration, or check the manufacturer's specification. The exact group depends on the precise trim, engine and model year, so check your specific reg rather than the model name.
Cars often rated around group 45 include the Audi RS 4 Avant, higher trims of the BMW 4 Series/M4, the Ford Mustang 5.0 V8 GT, Mercedes-AMG C-Class and GLC, and performance versions of the Range Rover Sport, Porsche Macan and Jaguar F-Type. Groups vary by trim, so always verify your exact registration.
Yes. Choosing a lower-powered trim of the same model, or a car a few groups down (see group 44), can cut the premium noticeably. Dropping into the teens or 20s — a smaller-engined hatchback or saloon — typically saves the most.
No. The group is one factor among many. Your age, address, annual mileage, occupation, no-claims discount and how you pay all influence the final quote — often more than the group number itself. That is why two drivers in the same group 45 car can pay very different premiums.
