Car Insurance Groups 21 to 30 UK: What to Expect on Premiums

What groups 21 to 30 represent

The UK insurance group scale runs from 1 to 50, with the recommendation set by the Group Rating Panel administered by the Association of British Insurers using engineering data from Thatcham Research. Groups 21 to 30 sit above the mainstream family-car band and below the high-performance and luxury territory. They are the cars that are bigger, better equipped or quicker than the average commuter hatchback.

Cars reach this band through a combination of higher list price, larger or more powerful engines, more complex bodywork and more expensive technology. A mid-size SUV with adaptive cruise control, parking sensors and a panoramic roof costs far more to repair after a collision than a basic supermini, and that feeds directly into a higher group.

For owners, the practical message is that premiums in these bands are typically a clear step up from family-car rates. The cars offer more space, comfort and badge appeal, but the cost of putting them right after an accident, and of replacing them when written off, is higher.

Examples of cars in these groups

This band commonly holds mid-size and larger SUVs, premium compact cars and estates, and entry-level executive saloons. Many versions of the Nissan Qashqai, Kia Sportage, Hyundai Tucson, Ford Kuga, Volkswagen Tiguan, Audi A3, BMW 1 Series, Mercedes-Benz A-Class, Volvo XC40 and Skoda Superb appear across groups 21 to 30 depending on engine and trim.

Higher-powered diesels and larger petrol engines tend to sit at the top of this band, while smaller-engined or hybrid versions of the same model may sit lower. Premium badges often rate higher than mainstream rivals of similar size, partly because of pricier parts and partly because of higher repair labour rates at franchised dealers.

As always, the group attaches to the exact specification. A premium compact car in a modest trim might sit in the low twenties, while the same model with a sport package and a powerful engine climbs well past group 30.

Why technology raises repair costs in this band

One of the biggest reasons cars in groups 21 to 30 cost more to insure is the technology built into them. Cars in these bands frequently carry radar units, cameras and sensors that power lane assist, automatic emergency braking and adaptive cruise control. These components sit in bumpers, windscreens and mirrors, exactly the areas damaged in minor collisions.

Thatcham Research has highlighted that repairing or recalibrating advanced driver-assistance systems after even a low-speed knock can add significantly to a claim. A bumper that once cost a modest sum to replace may now require sensor recalibration and a specialist garage, lifting the repair bill and the group.

This is why two cars of similar size and price can sit in different groups: the one with more standard assistance technology generally rates higher because the expected cost of putting it right is greater. Buyers weighing running costs should bear in mind that more gadgets often means a higher group.

How personal factors interact with the group

Even in the upper-middle band, the insurance group is only part of the price. The Financial Conduct Authority permits insurers to use many rating factors, and a strong personal profile can offset a higher group. A mature driver with a full no-claims history in a group 26 SUV may pay less than an inexperienced driver in a group 12 hatchback.

Postcode, overnight parking, annual mileage, occupation and the chosen excess all play their part. Because these cars are more valuable, theft risk and where the car is kept matter more than they might for a cheap city car. A secure driveway or garage can make a meaningful difference to the quote on a desirable SUV.

The FCA's pricing rules, in force since January 2022, also apply here: insurers cannot charge a loyal customer more than a new one for the same policy. Reviewing the renewal each year and comparing equivalent cover remains a sensible habit for owners of cars in this band.

Owning a car in groups 21 to 30

Drivers in this band can manage costs in several ways. Choosing a smaller-engined or hybrid version of a desired model often pulls the group down. Specifying fewer optional extras, particularly large alloy wheels and performance packs, can also keep the rating lower, since modifications and high-spec trims tend to lift the group.

Security investment pays off more on these cars because they are attractive to thieves. A Thatcham-rated alarm or tracking system, secure overnight parking and sensible key storage all support a lower-risk profile. Keeping the car standard and declaring any genuine changes protects the validity of the policy.

For total-loss situations, owners should understand that a settlement reflects the market value at the time of the claim, which for a depreciating SUV or premium car can be well below the price paid new. Guaranteed asset protection products exist to bridge that gap on finance, though they are a separate product to weigh on their own merits.

Frequently asked questions

Why are SUVs often in groups 21 to 30?

Mid-size and larger SUVs tend to have higher list prices, bigger engines, more bodywork and more driver-assistance technology than family hatchbacks. All of those raise the expected repair and replacement cost, which lifts them into the upper-middle bands.

Does driver-assistance technology really increase my premium?

It can. Sensors and cameras in bumpers and windscreens are expensive to replace and recalibrate after an impact, so cars carrying a lot of this technology often rate higher. Thatcham Research has flagged the rising repair cost of these systems.

Will a hybrid version of the same car be a lower group?

Sometimes, particularly where the hybrid has a smaller or less powerful engine, but not always, because battery and component repair costs can offset the gain. Checking the group for the specific variant is the reliable approach.

How much can my personal profile reduce the premium?

Substantially. Age, no-claims history, postcode, mileage and excess all interact with the group, so an experienced low-risk driver in a group 27 car may pay less than a high-risk driver in a much lower group.

Is comprehensive cover worth it on a car in this band?

Comprehensive covers your own vehicle as well as third parties, which matters more for the higher values in this band. The cover level is a personal decision, but on a valuable car the protection of comprehensive is usually significant relative to the extra cost.
