Gas Safety & CP12 in Hillingdon

Outer-west London brings larger family properties and more system boiler installs into the gas safety mix, and Hillingdon sits squarely in that band. The borough covers UB3, UB4, UB7, UB8, UB9, UB10, HA4, and HA6, with Uxbridge at the centre and Hayes, Ruislip, Northwood, West Drayton, Ickenham, Eastcote, and Yiewsley filling out the housing footprint. The borough's 1930s semi stock plus post-war estates in Hayes and Edwardian and inter-war housing in Ruislip and Northwood means a typical CP12 visit covers a boiler, a fire, and a cooker rather than a single combi. Affinity Water supplies hard mains. Our Gas Safe registration is 972173 (verifiable at gassaferegister.co.uk).

The Gas Safety (Installation and Use) Regulations 1998 (GSIUR 1998) Regulation 36 sets the landlord's annual inspection duty. The Landlord Gas Safety Record, also called a CP12, is issued within 28 days of the check, and the tenant receives their copy inside the same 28-day window. New tenants must have a copy before they take occupation of the property.

Each appliance is visually inspected for damage and combustion residue, working pressure is measured in kPa against the manufacturer data plate, gas tightness is verified using a calibrated digital manometer, flue flow is proven with smoke pellets for open-flue appliances or an anemometer for room-sealed plant where indicated, and ventilation is calculated against BS 5440-2 for every open-flue installation against the dwelling's habitable volume.

Pricing excludes VAT. CP12 with up to three appliances is 125 pounds, each extra appliance is 20 pounds, the CP12 and annual boiler service combination is 210 pounds at the same visit, and a second boiler at the same visit is 95 pounds.
