Key takeaways
- Every gas appliance, fitting and flue you provide must be checked every year by a Gas Safe registered engineer.
- Give existing tenants the record within 28 days and new tenants before they move in.
- You can renew up to two months early and keep the original expiry date.
Why it matters
The Gas Safety (Installation and Use) Regulations 1998 make landlords responsible for gas safety in their rental properties. Faulty appliances can cause fires, explosions and carbon monoxide poisoning.
Breaches are a criminal offence and can lead to unlimited fines or prison. Without a valid record you may also be unable to serve some possession notices.

FAQs
What if my tenant won't let the engineer in?+
Keep written records of every reasonable attempt to gain access. This shows you took all reasonable steps.
Is a CP12 the same as a gas safety certificate?+
Yes. CP12 is the old name for the Landlord Gas Safety Record, and people still use it.
Do I need one if there's no gas?+
No. If the property has no gas supply, you don't need a gas safety record.
