Gas Safety & CP12 in Kingston upon Thames

Kingston upon Thames brings a substantial family-house stock to the gas safety patch, with system boiler upgrades and bathroom refurb work running steady year-round. The borough covers KT1, KT2, KT3, KT5, KT6, and KT9, including Surbiton, New Malden, Norbiton, Berrylands, Tolworth, and Chessington. Edwardian and 1930s suburbs dominate, with riverside apartments in Kingston centre and Victorian terraces in Surbiton. Two water companies serve the borough (Thames Water and SES Water) which means scale management on heat exchangers is a constant consideration we factor into recommendations. Our Gas Safe registration is 972173 (verifiable at gassaferegister.co.uk).

Under Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998 (GSIUR 1998), every landlord must arrange an annual gas safety check on each appliance and flue serving a let property. 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. Renewals are dated against the existing certificate so the rolling 12-month cycle never drifts out of compliance.

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 tested using a calibrated digital manometer with a let-by check first, flue flow is verified 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, CP12 plus annual boiler service combined is 210 pounds at the same visit, and a second boiler at the same visit is 95 pounds.
