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 Bromley as it does across England, and an HMO licence can add its own conditions on top.
Gas safety in Bromley — local property context
Bromley is London's largest borough by area, at 59 square miles, and over half of it is open countryside, much of it Metropolitan Green Belt. Semi-detached houses are its most common home type, at 29.9% of households (Census 2021). Of 143,430 council tax properties, 25.7% were built in the 1930s and 34.6% between 1945 and 1982 (VOA 2025).
Census 2021 counted 23,661 Bromley households renting privately, 17.4% of the total and the third lowest share of the 33 London boroughs. Our Gas Safe registered engineers are experienced with the boilers, gas fires and appliances typically found in properties across the BR3, BR2, BR5, BR6, BR1, SE20, BR4, BR7, TN16, SE9, SE26, SE19 postcode areas, and regularly carry out CP12 inspections across Bromley for private landlords, letting agents and HMO operators.
