Landlord gas safety certificate

If you let a home with gas appliances you provide, the law requires a gas safety check every 12 months by a Gas Safe registered engineer, and a copy of the record for your tenants. The landlord database will also ask for it.

Questions landlords ask

Do landlords have to provide a gas safety certificate?

Yes, where there is a gas appliance, fitting or flue the landlord provides. Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998 requires a safety check every 12 months by a Gas Safe registered engineer and a record given to tenants.

How often is a landlord gas safety check needed?

Every 12 months. You can have the check done 10 to 12 months after the last one and keep the original expiry date; if you do, keep the record until two further checks have been carried out.

When must tenants get a copy?

Existing tenants within 28 days of the check. New tenants before they move in. Keep records for at least two years.

How much does a landlord gas safety certificate cost?

There is no set price; Gas Safe registered engineers set their own fees, which depend on the number of appliances. Check the engineer is registered and qualified for the appliance types in your property.

What is a CP12?

“CP12” is an old trade name for the landlord gas safety record. The law requires the record, not a particular form; it must list each appliance and flue checked, the engineer’s name, registration number and signature, the date, and any defects and action taken.
