How to cancel

To cancel your car insurance with Diamond, you'll need to call them. You'll also need to pay a cancellation fee of £55, or £155 if you have a black box installed.

Heads up, though: we AREN'T Diamond! We're Cuvva. While we can't cancel your policies with other companies ourselves, we can help you on your way with our nice explainer below - just make sure you contact the right company directly.

(Note: the information in this article was valid at the time of publication in November 2020. Always double-check with your insurer.)

Cancellation fees

  • If you cancel during the cooling-off period, you'll have to pay a £25 cancellation fee
  • If you cancel after the cooling-off period has ended, you'll have to pay a £55 cancellation fee

How refunds work

When you cancel a car insurance policy, you'll usually have to pay a fee. The fee depends on the insurance company. It also depends on whether you're still your cooling-off period.

You'll get the rest of your policy refunded, if you paid for the whole year up front. But Diamond will take away some of that refund to cover the insurance you've already had. They'll charge you a cancellation fee on top of this. It's pretty standard across most car insurance companies.

Cancelling optional extras

You can add "policy upgrades" to your Diamond car insurance. These include:

  • Breakdown cover
  • Extra care
  • Hire vehicle
  • Keycare
  • Motor legal protection
  • Personal injury

All these optional extras can be cancelled separately, and you won't be charged a cancellation fee.

If you cancel them before they start, or while you're still in your cooling-off period, you'll get a full refund.

If you cancel outside your cooling-off period, you'll get a refund, minus a chunk taken away for the time you've been covered.

Cancelling after you make a claim

Like most car insurance companies, Diamond won't give you any refund on your car insurance if you've made a claim. But you'll still have to pay a cancellation fee.

And if you pay monthly for your car insurance, you'll need to pay up for the rest of the policy when you cancel. Again, this is standard in insurance.

This also applies to a lot of Diamond's car insurance add-ons, like breakdown cover, hire vehicle cover and motor legal protection. This is the same with most insurance companies.

The cooling-off period

By law, every car insurance policy comes with a cooling-off period. The cooling-off period is either 14 days from the day your policy starts, or 14 days from when you get your policy documents in the post.

Check your policy documents to find out when your cooling-off period starts and ends.

It's usually cheaper to cancel during your cooling-off period. And most insurance companies have one cancellation fee within the first 14 days, and a different (higher) cancellation fee if you cancel after the 14-day cooling-off period.

Whether you're in your cooling-off period or outside of it, your insurer will take away some money from your refund to cover the days of insurance you've already had.

How cooling-off periods work
A cooling-off period is a 14-day window you get to cancel your car insurance.


Diamond will automatically renew your car insurance after a year - and often at a higher price. If you don't want your car insurance to renew, you'll need to let them know.

Letting your policy "lapse" (which means not renewing it) is not the same as cancelling your policy mid-way through.

Diamond will contact you about a month before the policy renews to let you know:

  • That it's going to renew, and
  • How much it will cost when it does renew
