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 Barnet as it does across England, and an HMO licence can add its own conditions on top.
Gas safety in Barnet — local property context
Little of Barnet's housing predates 1900: 6.5% of council tax properties, against 20.9% across London, while 21.2% were built in the 1930s alone (VOA 2025). Detached houses hold 10.1% of households, against 6.1% London-wide, purpose-built flats 36.6% and terraced houses only 14.9%. A further 1.3% live in a commercial building, such as a flat over a shop (Census 2021).
In 22 of Barnet's 24 wards at least a fifth of homes are privately rented, rising to 48% in Golders Green (Census 2021). Our Gas Safe registered engineers are experienced with the boilers, gas fires and appliances typically found in properties across the EN5, NW9, HA8, NW11, NW4, N12, NW7, N3, N2, EN4, N20, NW2, N11 postcode areas, and regularly carry out CP12 inspections across Barnet for private landlords, letting agents and HMO operators.

Gas safety in Barnet: under 12 months old on the day it is sent
Barnet counts a gas safety certificate's age on the day it reaches the council, not the day of the check. HMO licence condition 3 requires a copy of the current certificate to be submitted every year, no more than 12 months old at the date of submission. A copy sent late in its year can already be out of date when it arrives, so send it soon after each annual check.
