Car Insurance Group 45: Cars & Cost (2026)
A group 45 car typically costs a mid-range UK driver around £1,600–£2,500+ a year for comprehensive cover in 2026 — the group covers powerful performance and luxury models near the top of the 1–50 scale.
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.
Group 45 insurance cost by driver age (2026)
The figures below are indicative annual comprehensive premiums for a typical group 45 car, held constant, to isolate the effect of driver age. Real quotes vary widely by postcode, mileage, claims history and the exact model — always compare live quotes.
| Driver age band | Indicative annual premium (comprehensive) | Notes |
|---|---|---|
| 17–24 | £4,500–£9,000+ | Young, low-experience drivers face the steepest loading on high-group cars; many insurers decline. |
| 25–34 | £2,200–£3,800 | Falls sharply once a no-claims record builds. |
| 35–64 | £1,600–£2,500 | Lowest band for most drivers — settled address, full no-claims, low mileage. |
| 65+ | £1,800–£3,000 | Rises modestly again at older ages on performance models. |

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 policy — telematics can help younger drivers on high-group cars.
