A Landlord Safety Certificate, also known as a Gas Safety Certificate or CP12, is a legal requirement for all landlords in the UK who rent out properties with gas appliances. It confirms that all gas appliances, pipework, and flues have been inspected by a qualified Gas Safe engineer and found to be in safe, working order.
At Citywide Plumbers, we specialise in issuing Gas Safety Certificates across London, helping landlords stay compliant and tenants stay protected.
Why Landlords in London Need a Gas Safety Certificate
The Gas Safety (Installation and Use) Regulations 1998 require landlords to:
-
Arrange annual gas safety checks
-
Use a Gas Safe registered engineer
-
Provide tenants with a copy of the certificate within 28 days
-
Keep records of gas safety for at least two years
Failure to comply could result in heavy fines, legal penalties, and even imprisonment. Insurance claims may also be invalidated in the event of a gas-related incident without a valid certificate.
Citywide Plumbers helps landlords across London avoid these risks through efficient, reliable gas safety inspections performed by certified engineers.
What Our Safety Certificate Covers
When you book with Citywide Plumbers, our Gas Safe engineers inspect all gas-related elements of your property, including:
-
Gas appliances such as boilers, cookers, and fires
-
Pipework and connections
-

-
Safety controls and shut-off mechanisms
