Understanding Car Insurance Groups
Every car in the UK is assigned an insurance group from 1 to 50. Group 1 cars are the cheapest to insure, while group 50 cars are the most expensive. Knowing a car's insurance group before you buy can help you budget for running costs.
How Insurance Groups Are Determined
Several factors influence which group a car is placed in:
- Vehicle value – More expensive cars cost more to replace
- Performance – Faster cars are statistically more likely to be in accidents
- Repair costs – Parts prices and labour time for repairs
- Security – Standard security features like alarms and immobilisers
- Safety ratings – Euro NCAP crash test results
- Bumper compatibility – How well bumpers absorb impact in low-speed crashes
Insurance Group Ranges Explained
Here's a rough guide to what you'll find in different group ranges:
- Groups 1-10 – Small city cars, older vehicles, low-powered hatchbacks (e.g., Fiat 500, VW Up, Skoda Citigo)
- Groups 11-20 – Family hatchbacks, small SUVs, most mainstream models (e.g., Ford Focus, VW Golf base models)
- Groups 21-30 – Larger family cars, performance variants, executive cars (e.g., BMW 3 Series, Audi A4)
- Groups 31-40 – Sports cars, large SUVs, premium vehicles (e.g., BMW M Sport, Range Rover Sport)
- Groups 41-50 – Supercars, high-performance sports cars, luxury vehicles (e.g., Porsche 911, Ferrari, Lamborghini)
Tips for Cheaper Car Insurance
If you're looking to reduce insurance costs:
- Check the insurance group before buying a car
- Consider lower-powered versions of the same model
- Add approved security devices to potentially lower your premium
- Compare quotes from multiple insurers – groups are a guide, not a fixed price
- Consider telematics (black box) policies if you're a safe driver
- Build up a no-claims bonus over time
Best Cars for New Drivers
New drivers typically pay higher premiums, so choosing a car in a low insurance group is essential. Look for:
- Cars in groups 1-10
- Engine sizes under 1.2 litres
- Vehicles with good safety ratings
- Popular models with cheap, readily available parts
