Gas safety certificate expiry in England: renew early
Last updated 27 Oct 2026
In England, a landlord's gas safety check done in the 2 months before its deadline counts as done on the deadline, so renewing 10 to 12 months after the last check keeps the original anniversary date. A check done earlier than that starts a new 12-month clock. This page covers England; the Gas Safety (Installation and Use) Regulations 1998 also apply in Wales and Scotland, but their possession rules differ.
For the yearly check itself, the 28-day copy rule and what the record must contain, see gas safety certificate: landlord rules and deadlines.
The 10-to-12-month window
Regulation 36(3) requires each gas appliance and flue you provide to be checked at intervals of no more than 12 months. Regulation 36A, in force since 6 April 2018, sets how the next deadline is worked out.
- The deadline date is the last day of the 12-month period in which the check had to be made (reg 36A(4)).
- Renew early, keep the date: a check completed within the 2 months ending with the deadline date is treated as made on the deadline date (reg 36A(1)).
- Renew earlier than that: the 2-month rule does not apply, so the next check is due 12 months after the date it was actually done.
| Deadline date | Next check done on | Next deadline date |
|---|---|---|
| 31 March 2027 | 20 February 2027 (within the 2 months) | 31 March 2028 |
| 31 March 2027 | 10 December 2026 (more than 2 months early) | December 2027, 12 months after the check |
Count from the date of the check shown on the gas safety record.
A one-off late check to line up appliances
Regulation 36A(2) and (3) let a landlord check an appliance or flue in the 2 months starting with its deadline date instead of before it. This can be used only once per appliance or flue, and only to align its deadline with another appliance or flue in the same property. It is not a general 2-month grace period.
What happens if it lapses
If the 12 months pass without a check, the landlord is in breach of regulation 36(3). Book a Gas Safe registered engineer as soon as you can, and keep a written record of every attempt to get access.
- It is a criminal offence. Breaching health and safety regulations is an offence under section 33(1)(c) of the Health and Safety at Work etc. Act 1974.
- The penalty in England and Wales, under Schedule 3A to that Act, is, on summary conviction, prison up to "the general limit in a magistrates' court" or a fine with no upper limit, and up to two years' prison or an unlimited fine in the Crown Court. The old £20,000 cap on magistrates' fines stopped applying in England and Wales on 12 March 2015 (SI 2015/664, Schedule 4 paragraph 7).
- The reasonable-steps defence. Regulation 39 says no one is guilty of breaching regulation 36 if they show they took all reasonable steps to prevent it. A dated trail of booking attempts and refused access is what supports that. See notice to enter and tenants who refuse access.
Possession and serving notice in England
Before 1 May 2026, a landlord who had not given the tenant the gas safety record could not serve a valid section 21 notice. That rule was in regulation 2 of the Assured Shorthold Tenancy Notices and Prescribed Requirements (England) Regulations 2015.
From 1 May 2026, section 21 notices can no longer be served on private tenancies in England. Those 2015 Regulations were revoked for private assured tenancies from the same date, subject to saving provisions. See how landlords get possession now that section 21 is abolished.
Possession now runs through section 8 of the Housing Act 1988. Section 8 itself sets no gas safety condition on serving a notice. A lapsed check is still a criminal offence whatever notice you serve.
Gas safety check vs boiler service
A gas safety check and a boiler service are different jobs, though one engineer can do both on the same visit.
| Gas safety check | Boiler service | |
|---|---|---|
| Required by | Regulation 36(3), every 12 months | Not named in regulation 36 |
| Covers | Every gas appliance and flue you provide, not just the boiler | Usually the boiler only |
| What it involves | At least the checks in regulation 26(9): flue, combustion air, operating pressure or heat input, and safe operation | Cleaning, adjusting and replacing parts, as the manufacturer recommends |
| Paperwork | A gas safety record, with a copy to the tenant within 28 days | A service report |
Regulation 36(2) separately requires every gas fitting and flue you provide to be maintained in a safe condition. Regular servicing is one way landlords meet that duty, but a service report is not a gas safety record. If you book both together, ask for both documents.
