Gas Safety & CP12 in Barnet

Gas safety inspections in Barnet cover a wide band of property types, from 1930s Metroland semis across Hendon and Mill Hill to the large Edwardian houses of East Finchley and the strictly regulated Hampstead Garden Suburb. We work the full borough footprint, EN4, EN5, HA8, N2, N3, N10, N11, N12, N14, N20, NW2, NW4, NW7, NW9, and NW11, with engineers who know which Golders Green mansion blocks require service-lift booking and which Whetstone properties still run open-flued back boilers. Our Gas Safe registration is number 972173 and you can verify it at gassaferegister.co.uk.

Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998 (GSIUR 1998) places the landlord under a non-delegable duty to arrange an annual gas safety check on every appliance and flue serving a rented dwelling. We issue the Landlord Gas Safety Record, also called the CP12, within 28 days of the inspection and tenants receive their copy inside the same 28-day window. For HMO properties common across the Hendon and Golders Green rental market we cover every shared appliance including kitchen cookers, communal hot water plant, and bedroom-flued fires.

Each inspection includes a visual condition check, working pressure measurement in kPa against the data plate, a let-by and tightness test on the gas installation using a digital manometer, flue flow verification with smoke pellets for open-flue appliances, anemometer checks for room-sealed flues where access dictates, and a ventilation calculation against BS 5440-2 for any open-flue fire or water heater.

Pricing excludes VAT. CP12 with up to three appliances is 125 pounds and each extra appliance is 20 pounds. Combine the CP12 with an annual boiler service at the same visit for 210 pounds. Hampstead Garden Suburb conservation constraints mean any follow-up gas pipe repair to BS 6891 carcassing is planned with appropriate fittings and route selection.
