For landlords

What happens if a gas safety certificate expires?

If a gas safety certificate expires, the landlord is in breach of the Gas Safety (Installation and Use) Regulations 1998 until a new check is done, even if the appliances are fine. There's no grace period. Letting with an expired record risks prosecution, and in England can block a Section 21 eviction notice.

The gas safety check must be done every 12 months, and there is no grace period. The moment a record lapses, the landlord is in breach of the Gas Safety (Installation and Use) Regulations 1998 until a new check is carried out, even if every appliance is working perfectly. The breach is about the missed deadline, not the state of the appliances.

What an expired record can cost you

You're in breach of your legal duty as a landlord until a fresh check is done.
Letting with an expired record risks prosecution and enforcement action.
In England, a landlord who never gave the tenant a valid gas safety record cannot serve a Section 21 (no-fault eviction) notice.

You can have the next check done up to two months early, any time from 10 months after the last one, and keep your original renewal date, so booking early never makes your annual date drift.

If your record has already expired, don't wait: book a Gas Safe registered engineer as soon as you can. This is general information on the rules, not legal advice on a specific tenancy.

Frequently asked

Is there a grace period after a gas safety certificate expires?

No. There is no grace period. As soon as the 12-month record lapses you are in breach of the Gas Safety (Installation and Use) Regulations 1998, even if the appliances are fine, until a new check is carried out.

Can I still evict a tenant if the gas certificate expired?

In England, a landlord who never provided the tenant with a valid gas safety record cannot serve a Section 21 no-fault eviction notice. This is a specific legal point, so if eviction is in question take proper advice.

How early can I renew before it expires?

Up to two months early. If you do the check between 10 and 12 months after the last one, your renewal date stays fixed to the original anniversary rather than resetting to the new check date.
