The Landlord Gas Safety Record (often called a CP12), confirming gas appliances and flues in a rented property have been checked annually by a Gas Safe engineer.
A CP12, properly the Landlord Gas Safety Record, confirms that the gas appliances, fittings and flues in a rented property have passed their annual safety check, carried out by a Gas Safe registered engineer.
