There is no informal grace period that makes an overdue check acceptable.

What should you do today if gas safety has expired?

Book a Gas Safe registered engineer for the earliest slot and say the record is overdue. Keep the booking confirmation. If a letting agent manages the property, confirm in writing who is arranging the visit — HSE guidance is that using an agent does not remove the landlord’s responsibility that the duties are met.

When the new record is issued, give existing tenants a copy within 28 days of the check (and new tenants before they move in), keep your copy for at least two years, and write the next anniversary down the same day.

How renewal works after an overdue check

The legal duty is a check at least every 12 months by a Gas Safe registered engineer, a record of that check, and tenant copies on HSE’s timetable. An expired record is not repaired by a calendar reminder. Get the inspection done, then reset the 12-month clock from the new check.

HSE describes an early-check window (a check up to two months before the due date can keep the original anniversary). That is not a general grace period after the date has passed. If the record has already lapsed, book immediately.

Record keeping after the new certificate arrives

HSE: keep the safety-check record for two years. Issue a copy to each existing tenant within 28 days of the check, and to any new tenant before they occupy. Store the PDF with the property, not only in the engineer’s email.

Why an expired gas safety certificate is serious

Gas safety duties exist because appliances, flues and fittings can kill. Enforcement sits with the relevant regulator and, where applicable, the local authority. This page does not invent fine amounts — read current HSE guidance for landlords. Insurers may also take a hard line if an incident occurs without a valid record.

Separately, missing prescribed documents can affect some possession routes. Fix the record before you rely on a notice process. That is not legal advice for a specific claim.

Tracking dates is not the same as legal compliance

A reminder product cannot inspect appliances, issue a gas safety record, or close an overdue gap. Certs Reminder stores the file you upload, the dates you confirm, and emails you at 30, 7 and 1 day before the next anniversary so a repeat is less likely. Always verify extracted dates against the document.

Frequently asked questions

What should a landlord do if their gas safety certificate has expired?

Book a Gas Safe registered engineer immediately, keep proof of the booking, complete the check, give tenants their copy, keep your record for at least two years, and diary the next 12-month date the same day.

Can I let a property with an expired gas safety certificate?

Do not leave gas safety outstanding. Arrange a valid check as soon as possible and keep the new record. This is general information, not a decision for a specific tenancy.

Is there a grace period if the CP12 has expired?

HSE does not describe a general informal grace period after the anniversary. You can sometimes check up to two months early and keep the original due date. Book as soon as you realise it has lapsed.

Will an expired certificate affect eviction?

Gas safety records form part of the wider prescribed-documents picture for some possession routes. An expired record is a risk to fix before relying on notice procedures. Take advice for your case.
