Gas Safety & CP12 in Lewisham

Lewisham's housing stock runs from Victorian terraces in Brockley and Forest Hill, through Edwardian villas in Honor Oak, to post-war estates in Lewisham proper and Catford. The borough covers SE4, SE6, SE8, SE12, SE13, SE14, SE23, and SE26, including New Cross, Sydenham, and Hither Green. Brockley sits inside a conservation area which dictates period-appropriate fittings on any visible carcassing follow-up, and Forest Hill and Sydenham have substantial Edwardian housing with original copper pipework now ageing into pinhole-leak territory. Thames Water serves the borough on moderate mains. Our Gas Safe registration is 972173 (verifiable at gassaferegister.co.uk).

The Gas Safety (Installation and Use) Regulations 1998 (GSIUR 1998), Regulation 36, places the annual inspection duty on the landlord. The Landlord Gas Safety Record (LGSR or CP12) is issued within 28 days of the inspection, 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 gas appliance is visually inspected for damage, combustion residue, and seal condition, working pressure is measured in kPa against the manufacturer data plate, gas tightness is tested using a calibrated digital manometer with a let-by check first, flue flow is proven with smoke pellets for open-flue appliances or an anemometer for room-sealed plant, 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.
