What is a Gas Safety Certificate (CP12)?
A Gas Safety Certificate, formally known as a CP12, is a document confirming that all gas appliances, flues and pipework in a rental property have been inspected by a Gas Safe Registered engineer and found to be safe. The engineer checks each appliance for correct operation, adequate ventilation, secure flue connections and correct gas pressure, and lists every appliance on the certificate along with its result.
Every private landlord in England has been legally required to hold a valid CP12 and renew it every 12 months since the Gas Safety (Installation and Use) Regulations 1998 came into force. This national duty applies in Richmond upon Thames as it does across England, and an HMO licence can add its own conditions on top.
