Gas Safety & CP12 in Wandsworth

Wandsworth gas safety work runs across Victorian terraces in Battersea and Tooting, riverside new-builds in Nine Elms and Battersea Power Station, 1930s semis in Putney, and the mixed stock around Balham, Earlsfield, and Wandsworth Town. The borough covers SW8, SW11, SW12, SW15, SW17, and SW18, including Clapham Junction. Nine Elms and Battersea Power Station have strict managing-agent access protocols, which means we book through the building pass system, and conversions across SW17 and SW18 often hide pitch-fibre drains plus dated gas carcassing routing that affects flue runs. 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 annual inspection duty for landlords. The Landlord Gas Safety Record (CP12 or LGSR) is issued within 28 days of the inspection, and the tenant receives their copy inside the same 28-day window. For Battersea Power Station and Nine Elms managed buildings, we always confirm access route and engineer pass ahead of the visit.

Each gas 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 with a let-by check first, flue flow is proven with smoke pellets for open-flue appliances or an anemometer for room-sealed plant on the higher-rise stock, and ventilation is calculated against BS 5440-2 for every open-flue installation in the dwelling.

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