Gas Safety Certificate Camden — from £64.99

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 Camden as it does across England, and an HMO licence can add its own conditions on top.

Gas safety in Camden — local property context

Few Camden households live in houses. At the 2021 Census, 8.1% of households lived in a terraced house, 3.6% in a semi-detached and 1.7% in a detached house, with most of the rest in flats. Camden's October 2024 licensing review found additional HMOs spread fairly evenly across the borough, apart from the parkland of Regent's Park, Primrose Hill and Hampstead Heath.

BRE modelling from 2020, quoted by Camden, estimates about 6,200 properties meet its additional HMO definition, against about 1,250 mandatory HMOs. In October 2024, 2,566 additional licences were in force. Our Gas Safe registered engineers are experienced with the boilers, gas fires and appliances typically found in properties across the NW3, NW1, NW6, NW5, WC1, NW2, NW8, EC1, N6, WC2 postcode areas, and regularly carry out CP12 inspections across Camden for private landlords, letting agents and HMO operators.

Gas safety in Camden: the yearly certificate the council expects

For licensed HMOs, Camden asks for more than a certificate on file. Condition 14 of its 2025-30 licence conditions applies where there is a gas supply. The licence holder must send Camden the current gas safety certificate every year and give copies to occupants.

That makes your CP12 renewal date a licensing deadline as well as a tenancy one. A gas certificate also belongs in a complete new or renewal licence application, so an application without a current certificate can be treated as incomplete.
