Gas Safety & CP12 in Richmond upon Thames

Richmond upon Thames brings a substantial volume of Grade II listed and conservation-area stock into every gas safety inspection, which means period-appropriate fittings and consent paperwork are part of the job rather than an extra. The borough covers TW1, TW2, TW9, TW10, TW11, SW13, and SW14, including Twickenham, Kew, Teddington, Barnes, East Sheen, Hampton, and St Margarets. Georgian and Victorian villas dominate Richmond and Kew, large Edwardian houses sit across Barnes and Teddington, and riverside flats line Twickenham. Thames Water and Affinity Water both serve parts of the borough on moderate-to-hard mains. Our Gas Safe registration is 972173 (verifiable at gassaferegister.co.uk).

Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998 (GSIUR 1998) places the annual inspection duty on the landlord. 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 Grade II listed properties we coordinate route surveys for any follow-up carcassing under BS 6891 and select fittings to suit the consent envelope.

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, and ventilation is calculated against BS 5440-2 for every open-flue installation.

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.
