Gas Safety & CP12 in Lambeth

Lambeth combines Victorian terraces in Clapham and Brixton, mansion blocks in Kennington, riverside towers in Vauxhall and Waterloo, and post-war estates in Streatham. The borough covers SW2, SW4, SW8, SW9, SW16, SE1, SE11, SE24, and SE27, including Stockwell, Tulse Hill, and Norwood. Vauxhall and Nine Elms regeneration has produced a heavy concentration of new-build apartment plumbing with managing-agent access requirements, and older Victorian supply runs across Brixton and Clapham increasingly need lead replacement which feeds into our follow-up scope after a CP12. Our Gas Safe registration is 972173 (verifiable at gassaferegister.co.uk).

Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998 (GSIUR 1998) imposes 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. For HMOs across SW9 and SW2 we cover every appliance, including bedroom-flued fires, communal cookers, and shared central heating plant, on a single certificate.

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 where indicated, 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. Active gas leak: ring National Gas Emergency on 0800 111 999 first, then us for shut-off, BS 6891 carcassing repair, and re-certification.
