Knowing when your car insurance is due is important for staying covered. Driving without valid insurance is illegal in the UK, even if it only lapses for a short time.
This guide explains how to find your car insurance expiry date, whether insurance renews automatically, and what to do when renewal is coming up.
How long does car insurance last in the UK?
Most car insurance policies in the UK last 12 months.
Your policy starts on a specific date and ends one year later, unless it is renewed. The exact end date depends on when you first took out the policy, not the calendar year.
For example, if your policy started on 15 March, it will usually expire on 14 March the following year.
How can I check when my car insurance runs out?
There are several simple ways to check when your car insurance expires. You can:
- Check your insurance documents or policy schedule
- Look at emails or letters from your insurer
- Log in to your insurer’s online account or app
If you are unsure or cannot find the details, you can also use the Motor Insurance Database (MID). This is an official UK database that shows whether a car is insured and often includes the policy end date.
If you’re a Marshmallow customer, you can check your policy end date in the app.
Does car insurance renew automatically?
Sometimes. Many UK car insurance policies renew automatically, but not all of them do. It depends on your insurer and how your policy was set up.
If your policy renews automatically:
- Your insurer will usually contact you before renewal
- The new policy will start immediately after the old one ends
- Payment is often taken automatically
If your policy does not renew automatically:
- Your cover will end on the expiry date
- You must arrange new insurance yourself
- Driving after this date means you would be uninsured
You should never assume your policy will renew. Always check your policy documents.
When will I get my car insurance renewal notice?
Most insurers send a renewal notice around 21 to 28 days before your policy expires. This usually includes:
- Your renewal date
- The new policy price
- Any changes to terms or cover
- Instructions on how to renew or cancel
This notice may arrive by email, post, or through your online account. If you do not receive one, contact your insurer early so you are not caught out.
When can you renew your car insurance?
Most insurers send renewal details around 21 to 28 days before your policy ends. This is usually the point when people start reviewing their cover or deciding whether to switch.

What happens if my car insurance expires?
If your car insurance expires, and you do not renew or replace it, you:
- Are no longer legally insured
- Cannot drive the car, even briefly
- May face fines, penalty points, or vehicle seizure
Even parking a car on a public road without insurance can cause problems. This is why knowing exactly when your insurance runs out matters.
Summary
Most UK car insurance policies last 12 months, and you need to know the exact expiry date to stay legally covered. You can check when your insurance runs out through your policy documents, your insurer, or the Motor Insurance Database.
Some policies renew automatically, but many do not. Checking well before renewal can help you avoid gaps in cover and unnecessary stress.
