Landlords with gas appliances in privately rented homes in England are generally expected to arrange a check by a Gas Safe registered engineer on a regular cycle — commonly discussed as annual for the relevant appliances — and to keep evidence that the check happened.
“How long does a gas safety certificate last?” usually means “when must the next check be done?” Official materials set out which appliances are covered, how tenants receive a copy, and retention periods. Confirm current GOV.UK / HSE guidance for your nation and property before you act.
Annual check expectations (England PRS)
For many private rented scenarios in England, landlords plan gas safety on an annual rhythm: book the engineer before the previous certificate runs out, file the new record against the correct address, and diary the next visit from the dates on the certificate — not from memory.
Landlords often call the document a “CP12”. Keep the actual certificate your engineer issues and follow official naming and copy rules for your situation. Do not assume a software status badge replaces the engineer’s record.
Why expiry dates get missed
- The PDF only lives in email, then the mailbox is cleared.
- A calendar reminder sat on a phone that was replaced.
- Two similar boilers — certificates filed under the wrong flat.
- Tenant copy assumed (“they must have it”) with no date or method logged.
- Renewals cluster with boiler call-outs, invoices and tenancy turnovers.
What to keep on file
- Certificate PDF or scan matched to the property address.
- Issue date and expiry (or next-check) date.
- Engineer name and Gas Safe registration details.
- Appliance notes from the certificate, if listed.
- Date and method any tenant copy was provided.
- Follow-up repairs the engineer flagged, with completion dates.
A simple renewal rhythm
- Confirm which appliances at this address need checking under current rules.
- Book a Gas Safe registered engineer with enough lead time.
- File the certificate against the correct property immediately.
- Log issue and expiry dates somewhere you will see them again.
- Set reminders ahead of expiry (for example 90 / 30 / 14 days).
- Record remediations so the next engineer has context.
