What Is a Gas Safety Certificate (CP12)?

A Gas Safety Certificate, often referred to as a CP12, is a legal document that confirms gas appliances, pipework and flues within a rental property have been inspected by a Gas Safe Registered engineer. The inspection helps ensure gas installations are operating safely and identifies any issues that may require attention. Once the inspection is complete, you’ll receive a Gas Safety Certificate detailing the appliances tested and the results of the inspection.
