Key facts
- Frequency: at least every 12 months from the check date, not “sometime this year”.
- Who: a Gas Safe registered engineer.
- Tenant copy: existing tenants within 28 days of the check; new tenants before they move in.
- Keep your copy: at least two years.
- Grace period: HSE guidance does not describe an informal grace period.
What is the 12-month gas safety rule?
HSE guidance on the Gas Safety (Installation and Use) Regulations is that landlords must have relevant gas appliances, fittings and flues checked for safety every 12 months by a Gas Safe registered engineer, keep a record, and give tenants a copy on the stated timetable.
Track the exact anniversary of the last check — not “sometime this calendar year”. If the last check was 14 March, complete the next check before 14 March the following year.
How often vs how long — same clock, different question
“How often do I need a gas safety certificate?” asks about the booking cycle. “How long does a gas safety certificate last?” asks about validity. For a landlord record both answers are 12 months from the check date. Use this page for the renewal rhythm; use the validity guide for grace-period and “how long” wording.
When must tenants receive the gas safety record?
HSE: existing tenants should receive a copy of the record within 28 days of the check. New tenants should receive a copy before they occupy. Keep your own copy for at least two years.
If you use a letting agent, put in writing who books the engineer and who issues the tenant copy. Using an agent does not remove the landlord’s responsibility that the duties are met.
Can you do the check early and keep the same renewal date?
HSE explains that, under regulation 36A, a check completed up to two months before the deadline can still keep the original anniversary. That helps you book early. It is not a general grace period after expiry. A later check is only allowed in limited, one-off cases to align appliance dates in the same premises.
There is no informal grace period after the anniversary. If the record has already lapsed, treat it as urgent and use the expired-certificate guide.
How to renew without missing the anniversary
Book a Gas Safe engineer at least 30 days out. After the visit, store the new record, give tenants their copy, and reset the next 12-month date the same day. Certs Reminder can email you at 30, 7 and 1 day — it does not carry out the check or make an expired record valid.

Frequently asked questions
How often do I need a gas safety certificate?
At least every 12 months from the date of the last check, by a Gas Safe registered engineer, with a record kept and a copy given to tenants as HSE describes.
Is gas safety every 12 months or every calendar year?
At least every 12 months from the check date — not “sometime this year”. Track the exact anniversary.
Who can carry out the check?
A Gas Safe registered engineer. Ask for their Gas Safe ID and keep it with the record.
Does “gas safe renewal” mean the landlord certificate?
People often mix up the engineer’s Gas Safe registration card with the landlord gas safety record (sometimes called a CP12). This page is about the annual landlord check and record, not the engineer’s own registration.
