How long is a landlord gas safety certificate valid?
Under the Gas Safety (Installation and Use) Regulations, landlords must arrange a gas safety check at least every 12 months by a Gas Safe registered engineer and keep a record. Treat the certificate as valid until the next due date on that cycle — usually one year after the check.
If the engineer records an earlier date, follow the earlier date. Always read the certificate itself rather than guessing from memory.
What should you do before the 12 months end?
Book a Gas Safe engineer at least 30 days before expiry, give tenants a copy of the new record when it arrives, and update your next due date the same day. Certs Reminder can email you at 30, 7 and 1 day so the booking does not slip.
Frequently asked questions
How long does a gas safety certificate last in the UK?
For landlords, the check and record must be renewed at least every 12 months. The certificate lasts until the next annual check is due.
Is a gas safety certificate valid for longer than a year?
Not for the landlord annual duty. Do not rely on a certificate that is older than 12 months for a rental with gas appliances or a gas flue.
How do I remember the expiry date?
Store the next due date per property and set reminders 30, 7 and 1 day before. Create a free Certs Reminder account if you want email alerts.
