Car insurance in the UK usually auto-renews unless you actively cancel it. Your insurer has to send you a renewal notice in good time before the policy expires — in practice most send it between 21 and 30 days out — and if you don’t act, the new policy starts on the expiry date at the price they quoted. The rules that govern all of this changed in January 2022, and they’re worth understanding before you either let auto-renewal happen or don’t.
What your insurer has to tell you
For general insurance policies that last 10 months or more — which covers almost all car insurance — the FCA’s rules (ICOBS 6.5) require the insurer to issue a renewal notice in good time before expiry. The notice must include the new premium and, crucially, what you paid last year, so you can see the change at a glance.
That last-year comparison has been a requirement since April 2017. Before then, insurers could quietly raise the price each year and most customers never noticed. Now it’s on the renewal document in black and white.
The 2022 price-walking ban
From 1 January 2022 the FCA’s general insurance pricing rules banned “price walking”. Under the rules, insurers can no longer quote an existing customer a higher price at renewal than they would quote a new customer buying through the same channel.
Before the change the loyalty penalty was large and well-documented. The FCA estimated the new rules would save consumers around £4.2 billion over ten years.
What the rules don’t do: they don’t guarantee you the cheapest price on the market. They only stop your current insurer charging you more than they’d charge a new customer with identical details. A different insurer can still be significantly cheaper, which is why shopping around still matters.
How to find your renewal date
- Your policy schedule or certificate — the expiry date is on the front page.
- Your insurer’s app or online account area.
- Any email thread titled “your renewal” or “your policy documents”.
- Direct debit records, if you’re paying monthly — the annual cycle starts at policy inception.
- As a last resort, the askMID service will confirm your vehicle is insured but doesn’t publish the expiry date.
Why you should still shop around
The price-walking ban fixes one specific problem — being charged more than a stranger — but it doesn’t touch the underlying variation between insurers. Quotes from different providers for the same driver on the same car on the same date routinely vary by hundreds of pounds. Some of that is risk appetite, some is marketing spend they need to recoup, some is just noise in the model.
The practical consequence: running your details through a comparison site every year is still worthwhile, even under the new rules. It takes about ten minutes. The saving, when there is one, is usually much more than ten minutes of minimum wage.
When auto-renewal actually makes sense
Letting your policy auto-renew isn’t automatically a mistake. It can be the right call when:
- You’ve checked the renewal price against a comparison site and your insurer is still competitive.
- You’ve got a no-claims discount or named-driver arrangement that’s non-trivial to transfer.
- You’ve recently had a claim or a driving conviction that’s pushed your premiums up everywhere — switching mid-cycle can sometimes trigger worse pricing than staying put.
- The renewal quote is cheaper than last year and a quick comparison doesn’t beat it meaningfully.
The point is that auto-renewal should be a choice, not a default that happens because you didn’t open the email.
Set a reminder three to four weeks out
Three to four weeks before your expiry date is the sweet spot. It’s early enough that you’ve got time to compare, call your current insurer if a cheaper quote comes up, and switch without a gap in cover. It’s late enough that the comparison quotes are fresh — some go stale after 30 days.
A calendar event works. A dedicated tracker works better if you’ve got several renewals to juggle, because they all follow the same pattern: car, home, pet, gadget. DuePings was built specifically for this use case — add the renewal, set a reminder at 30 days out, and forget about it until you’re nudged.
This is general information about how car insurance renewal works in the UK, not financial or regulatory advice. Always check your own policy documents and the current FCA Handbook for the rules that apply to you. Regulatory rules change — this page was written in April 2026 based on the FCA rules in force at that time.
