Insurance group 21: what it means & typical cost
Quick answer
Insurance group 21 sits in the "medium" band on the UK's 1–50 scale. A typical annual premium estimate for a group 21 car is £520–£815 (estimate only, not a quote) for a driver aged 30–49 in a medium-risk postcode.
What does group 21 mean?
Mid-size family cars, warm hatches and compact SUVs sit in this band, with average performance, value and repair complexity. Ratings on this 1–50 scale come from the Group Rating Panel — run jointly by Thatcham Research and the ABI — so group 21 means the same thing whichever car carries it, whether it's a compact hatchback or a performance model. Read our insurance groups explained guide for how the panel scores every car.
Groups 19–23 sit closest to it in cost, so they're worth comparing if you're weighing up a slightly cheaper or slightly pricier trim.
How much is insurance group 21?
On our published methodology, the insurance group 21 average cost is about £650 a year for a driver aged 30–49 in a medium-risk postcode on comprehensive cover, with most quotes falling between £520 and £815. That is the insurance group 21 cost before any no-claims discount is applied, so a settled driver with several claim-free years should expect to pay less than the midpoint. Age changes the picture completely: the same car gives a group 21 insurance cost of roughly £1,755 for a 17–20-year-old.
So is group 21 insurance expensive? Measured against the rest of the scale, it is about average — close enough to the midpoint of the scale that the car is rarely the thing making a quote painful. For context, our estimates put group 1 at around £220 a year and group 50 at around £1,275 on the same assumptions, which places group 21 in the medium band. The insurance group 21 price you are actually quoted will also move with your postcode, mileage, claims history and excess — the group sets the car-side base rate, not the final figure.
You will often see this written with a letter on dealer listings and quotes, as group 21E. The insurance group 21E cost is identical to plain group 21: the letter identifies which derivative was rated, not a separate price band. However you phrase it — an insurance group 21E average cost, an insurance group 21E price, or a 21E insurance group cost — you are asking about the same figure above.
Prefer to run the numbers on your own circumstances? The car insurance group 21E cost calculator on our pricing page lets you change the age band, postcode risk and cover type rather than accepting our midpoint. One thing we cannot give you is a car insurance quote for group 21E itself — no one can, because a quote prices the driver as well as the car, and the group is only the vehicle half of it.
The estimator sits on our group-by-group pricing page, and the insurance group prices table shows all fifty groups side by side. For the factors that sit outside the car entirely, see what affects car insurance price.

Why some group 21 cars show a letter, like 21E
You may see group 21 written with a letter suffix, such as 21E or 21D — the letter flags a specific trim or derivative, not a different cost scale. See our insurance group letters explained guide for what that means in practice.
