How Much Is Car Insurance for a 17 Year Old?
There's no single number, because the car matters as much as the age, but a 17 year old's insurance runs from around £140 a month in a low insurance group car to over £300 a month in a high group one, before any discounts.
The car you buy is the biggest choice you make before you’ve even shopped for a policy.
Comparison sites can only tell you a real number once you’ve picked a specific car, postcode and cover type. What they don’t make obvious upfront is how much of that number comes from the car itself, not just your age.
The detail
Here’s roughly what a 17-year-old’s annual premium looks like by insurance group:
| Insurance group | Est. annual premium | Est. monthly |
|---|---|---|
| Group 1 | ~£1,680 | ~£140 |
| Group 10 | ~£1,955 | ~£163 |
| Group 20 | ~£2,575 | ~£215 |
| Group 30 | ~£3,715 | ~£310 |
The gap between a group 1 car and a group 30 car, same driver, same address, same cover, is over £2,000 a year. That’s before you’ve compared a single insurer.
A handful of things move the number up or down from there: your actual postcode (insurers price by area, and the difference between a low-risk and high-risk postcode can be significant), whether the car is on a standard or telematics (“black box”) policy, how long you’ve held a licence, and whether you’re the main driver or a named driver on a parent’s policy.
What this means for your first car
Age 17 is fixed. The postcode is mostly fixed. The one lever you control completely, before you’ve spent anything, is which car you buy. A 17-year-old in a group 1 to 5 car is paying meaningfully less than the same 17-year-old in a group 20+ car, every single year the policy runs.
That’s the whole premise behind First Car Scout: see the insurance estimate next to the running cost for real cars in your budget, before you’ve fallen for one that turns out to be a high-group model in disguise.
