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 Sutton as it does across England, and an HMO licence can add its own conditions on top.
Gas safety in Sutton — local property context
Sutton's largest building era is the inter-war period: 40.6% of its 86,290 council tax properties date from 1919 to 1939, and 30.6% from the 1930s alone (VOA 2025). Semi-detached houses are home to 27.9% of households, and only 3.9% live in flats in converted or shared houses (Census 2021). The council's stock study adds that only about 5% of the borough's housing predates 1900.
The council's 2025 study estimated 942 HMOs in Sutton. Since 22 March 2026, HMOs of 3 or more people from more than one household need a licence. Our Gas Safe registered engineers are experienced with the boilers, gas fires and appliances typically found in properties across the SM1, SM6, SM5, SM2, SM3, KT4, CR0 postcode areas, and regularly carry out CP12 inspections across Sutton for private landlords, letting agents and HMO operators.
