What Happens If Your Gas Safety Certificate Expires? 2026 Guide for UK Landlords
Published: April 2026 · Reading time: 4 minutes
A gas safety certificate, formally a CP12, records an annual inspection of gas appliances, pipework and flues by a Gas Safe registered engineer.
What Happens If It Expires?
An expired record can expose a landlord to enforcement, complicate possession proceedings, create insurance problems and, most importantly, leave tenant safety unverified.
What Should You Do?
- Book a registered engineer immediately.
- Communicate with tenants and document access requests.
- Provide the completed record and retain copies.
- Set reminders ahead of the next annual deadline.
How to Avoid Missing the Next Renewal
Use a compliance calendar or property compliance software rather than relying on memory.
