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. Landlords in Westminster are subject to exactly the same obligation as landlords elsewhere in England.
Gas safety in Westminster — local property context
Westminster encompasses some of London's most valuable addresses — Mayfair, Marylebone, Pimlico, and Paddington — alongside significant social and private rented housing. The borough contains Georgian townhouses, Victorian mansion blocks, Edwardian purpose-built flats, and modern high-rises. Electrical installations vary enormously from original Victorian wiring in heritage properties to modern systems in Paddington Basin developments.
London's most central and premium residential borough. Rents are among the highest in the capital, with a sophisticated and international tenant base. Our Gas Safe registered engineers are experienced with the boilers, gas fires and appliances typically found in properties across the NW1, NW8, SW1, W1, W2, W9, WC1, WC2 postcode areas, and regularly carry out CP12 inspections across Westminster for private landlords, letting agents and HMO operators.
