For landlords, gas contractors, compliance managers and facilities teams handling landlord gas safety records and gas-service evidence. It is UK-focused and not legal advice.
A CP12, properly the Landlord Gas Safety Record, confirms that the gas appliances and flues in a rented property have passed their annual safety check, carried out by a Gas Safe registered engineer.
Who needs a CP12?
Landlords of residential rented property must ensure gas appliances, fittings and flues are checked for safety every 12 months under the Gas Safety (Installation and Use) Regulations 1998.
What the check covers
- That each appliance is burning correctly
- That flues and chimneys clear the products of combustion safely
- That safety devices function correctly
- That ventilation is adequate
- Any defects found, and the action taken
Records and deadlines
The landlord must give the tenant a copy of the record within 28 days of the check, or to a new tenant before they move in, and keep records for at least two years.
