Wondering “What insurance group is my car in?” You’re not alone. In the UK, every car is ranked in an insurance group from 1 to 50, and that rating can make a big difference to your premium. Cars in lower groups are usually cheaper to insure, while high-group models tend to cost more. Knowing your car’s insurance group—and what factors push it up or down—can help you compare policies, cut costs, and avoid surprises when it’s time to renew.
What Are Car Insurance Groups?
When buying car insurance in the UK, one of the most important factors affecting your premium is your car’s insurance group. Car insurance groups are a rating system created to classify vehicles based on the cost of insurance risk.
Insurance groups are numbered from 1 to 50, with group 1 vehicles being the cheapest to insure and group 50 vehicles being the most expensive.
The system was originally developed by the Group Rating Panel, a panel of UK insurers, to standardise how cars are classified for insurance purposes.
Factors That Determine Insurance Group
Several factors influence which insurance group a car falls into:
- Vehicle Value – Expensive cars cost more to repair or replace, placing them in higher groups.
- Engine Size and Performance – High-performance engines, fast cars, and sports cars are higher risk.
- Repair Costs – Cars with expensive parts or difficult repair procedures are rated higher.
- Safety Features – Vehicles with advanced safety features may fall into lower groups.
- Theft Risk – Cars frequently targeted by thieves are placed in higher insurance groups.
- Vehicle Age – Older cars can sometimes cost more to insure due to spare parts availability.
Note: Insurance groups affect premiums but are not the only factor—driver age, location, claims history, and mileage also impact your cost.
How Car Insurance Groups Work
- Group 1–5: Cheapest to insure. Typically small, low-powered cars like city cars and small hatchbacks.
- Group 6–15: Affordable mid-range cars, including family hatchbacks, small SUVs, and basic saloons.
- Group 16–25: Higher performance or larger vehicles, including executive saloons and sports variants.
- Group 26–35: Luxury and performance cars, some SUVs, and larger family cars.
- Group 36–50: High-end sports cars, supercars, and highly desirable vehicles with high repair costs or high theft rates.
Knowing your car’s insurance group can help you predict annual premiums and compare quotes across different insurers.
How to Check What Insurance Group Your Car Is In
You can check your car’s insurance group in several ways:
- Use the DVLA or Vehicle Documentation – Some car registration documents may indicate the insurance group.
- Visit Insurance Group Rating Websites – Many websites list insurance group ratings by make, model, and year.
- Use Total Car Check – Total Car Check provides a free initial vehicle report that will tell you a car’s insurance group.
Checking your car’s insurance group is especially useful before buying a used car, as it helps you anticipate insurance costs.
Why Insurance Groups Matter for Used Car Buyers
- Budget Planning – Knowing the insurance group helps you calculate the total cost of ownership.
- Comparison Shopping – Buyers can compare cars in similar groups to find better value.
- Avoid Surprises – Some cars may be cheap to buy but expensive to insure if they fall into a higher group.
For example, a small hatchback like a Ford Fiesta may fall in group 5, while a sporty Audi S3 could be group 35, dramatically impacting annual premiums.
