Can I use the same Gas Safety Certificate for multiple London properties?
Wondering if one Gas Safety Certificate can cover multiple London properties? Discover the legal requirements for landlords and why each rental needs its own valid CP12. Citywide Plumbers ensures compliance for all your properties.
If you're a landlord managing several properties in London, you may be wondering whether one Gas Safety Certificate (CP12) can cover them all. The simple answer is no—each property legally requires its own individual certificate. At Citywide Plumbers, we ensure landlords stay fully compliant by issuing property-specific Gas Safety Certificates through our Gas Safe registered engineers.
What is a Gas Safety Certificate (CP12)?
A Gas Safety Certificate is a legal document confirming that all gas appliances, pipework, and flues in a property have been inspected by a qualified Gas Safe registered engineer and are safe to use. For landlords, having this certificate renewed annually is a legal obligation under the Gas Safety (Installation and Use) Regulations 1998.
Why One Certificate Can’t Cover Multiple Properties
Each property is treated as a separate legal entity in the eyes of UK gas safety law. That means:
-
Each rental must have its own inspection
-
Each must have a unique certificate
-
Each must be inspected by a registered engineer annually
A certificate is tied to the specific appliances, layout, and condition of a single address. Therefore, even if you own multiple flats in the same building, you cannot use one certificate for all.
Legal and Insurance Risks
Using one certificate for multiple properties is not just incorrect—it’s unlawful. If you’re found without the proper certification per property, you could face:
-
Legal fines or prosecution
-
Invalidated landlord insurance
-
Risk of eviction notices or tenancy disputes
-
Greater liability if a gas-related incident occurs
