When is my car insurance due?

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 covers how to find when your car insurance is due for renewal, whether your policy renews automatically, and what happens if yours runs out.

Key takeaways

• Most UK car insurance policies last 12 months and expire on a set date each year.
• You can check your renewal date in your policy documents, via your insurer's app, or on the Motor Insurance Database (MID).
• Some policies renew automatically but many don't, so always check rather than assume.
• Driving with expired insurance is illegal, even for a short time.

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.

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 find out when your car insurance runs out. Check for your insurance expiry date in:

• Your insurance documents or policy schedule
• Emails or letters from your insurer
• 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.

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 can you renew your car insurance?

Most insurers send renewal details around 21 to 28 days before your policy expires. Your renewal notice will usually include:

• Your renewal date
• The new policy price
• Any changes to terms or cover
• Instructions on how to renew or cancel

The notice may arrive by email, post, or through your online account or app. If you don't receive one before your car insurance expiry date, contact your insurer as soon as possible.

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

Driving without insurance in the UK is illegal. Even parking a car on a public road without insurance can cause problems. This is why knowing exactly when your insurance runs out matters.
