There is no grace period once a landlord gas safety certificate expires. In England, under the Gas Safety (Installation and Use) Regulations 1998 as amended, the record is valid for 12 months from the date of the check, and the duty does not pause when that date passes. The only flexibility runs the other way: the check can be carried out up to two calendar months before the due date while the original expiry date stays the same. This page sets out the 12-month rule, how early renewal works, and what follows if a record lapses.
Is there a grace period after a landlord gas safety certificate expires?
No grace period exists once a landlord gas safety record expires. In England, the Gas Safety (Installation and Use) Regulations 1998 as amended set no equivalent to the leeway drivers get with an MOT. HSE states that the record is valid for 12 months from the date of the check. The day after that, you can no longer show a current check for the appliances you provide.
The duty does not pause while you sort out a date. It continues every day the property is let. The only flexibility in the regulations sits before the deadline, not after it, and it is the two-month early renewal window described further down this page.
What the 12-month rule in Regulation 36 requires of you
Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998 as amended requires a safety check on every gas appliance and flue you provide for your tenant's use. The check must happen within 12 months before the tenancy starts, or within 12 months of the appliance being installed, whichever is later. After that, it repeats at intervals of no more than 12 months.
Only a person approved by HSE may carry out the check, which in practice means a Gas Safe registered engineer. Gas Safe is the official register for gas engineers in Great Britain. HSE is also clear that these duties stay with you as landlord. They cannot be handed to the tenant, not even through a full repairing and insuring lease.
A safety check is a legal duty about safety. It is not the same job as an annual boiler service, which is a maintenance visit and usually a warranty condition — see gas safety check or boiler service. For the wider picture of what the law asks of landlords, read landlord gas safety in England.
How to renew early without losing your original expiry date
You can have the annual gas safety check carried out up to two calendar months before the due date and keep the original expiry date. HSE confirms that the new record then runs as though the check had taken place exactly 12 months after the last one. This flexibility came in through the Gas Safety (Installation and Use) (Amendment) Regulations 2018, which amended Regulation 36.
HSE's reason is practical. Landlords should not have to wait until the final days of the year, when access problems can push them past the deadline. Nor should an early check quietly shorten the annual cycle each time it happens.
Inside the two-month window, your expiry date stays where it is. Outside it, the next deadline runs 12 months from the actual date of the check, so your anniversary date moves forward and you lose part of the year you have already paid for.
What happens if your landlord gas safety record lapses
A lapsed record puts you in breach of Regulation 36, and HSE enforces these duties in England. Breaches of the Regulations can be prosecuted in the criminal courts. It is also an offence to use, or allow the use of, a gas appliance you know or suspect to be unsafe.
Tenants have a direct route to HSE if you cannot produce a current record. HSE runs an online form, LGSR1, for reporting a property with no record of a gas safety check. Any defect listed on a record must be put right promptly, and an appliance thought to be dangerous must not be used until the work is done.
If the date has already passed, arrange a check with a Gas Safe registered engineer at the earliest date you can get. Keep a written trail of what you arranged and when. Evidence of your efforts matters if HSE or a court later looks at the gap.
The tenant will not let the engineer in — what can you do?
Refused access is the most common reason a gas safety record runs out, and the regulations give you no power to force entry. HSE is explicit on this point: nothing in the Gas Safety (Installation and Use) Regulations 1998 as amended authorises entry against the tenant's wishes. What HSE expects instead is evidence that you took all reasonable steps to comply.
- Keep every letter, email and message about appointments, with dates.
- Leave a notice with your contact details when an engineer calls and gets no answer.
- Write to the tenant explaining the legal duty and that the check is for their own safety.
- Offer the tenant the chance to arrange an appointment that suits them.
- Consider what your tenancy agreement allows if refusal continues.
HSE inspectors look for repeated attempts rather than a single missed visit. Whether your steps were reasonable is ultimately a matter for a court.
Does a new tenancy or an empty property need a fresh gas safety check?
An existing record stays valid for its full 12 months, even when the tenant changes. HSE confirms that if a new tenancy begins while the record still runs, you can pass that record to the new tenants rather than commissioning another check. The copy must reach them before they move in.
Appliances and flues still have to be safe before you re-let. Where you suspect tampering or vandalism during a void period, HSE advises a further check before you hand over the keys. HSE also suggests having the pipework checked and tested after a tenant moves out. Our guide on empty properties between tenancies goes into this in more detail.
How long to keep records and when tenants must get their copy
Regulation 36 requires you to keep each gas safety record for at least two years. HSE advises going further and keeping a record until two further checks have been carried out. That way you can always show the pattern of annual checks behind the current one.
Existing tenants must receive a copy within 28 days of the check. New tenants must receive a copy before they occupy the property. Electronic copies are acceptable where the tenant agrees and can access them, and a paper copy must be provided if the tenant asks.
The record itself must show the date of the check, the address of the property, your name and address as landlord or agent, and a description and location of every appliance and flue checked. The tenant's copy does not need the engineer's signature, provided it says a signed copy is available for inspection. If you want the next check booked in with a Gas Safe registered engineer, see our landlord gas safety certificate (CP12) page.
