Gas Safety & CP12 in Merton

Merton's gas safety work covers Wimbledon Village Edwardian villas, 1930s semis across Raynes Park and Morden, Victorian terraces in Colliers Wood, and ex-council stock in Mitcham. The borough covers SW19, SW20, CR4, and SM4, including Wimbledon Park and Merton Park. Wimbledon Village sits inside a conservation area which dictates period-appropriate fixtures on any follow-up work, and the larger family-house heating spec across SW20 means combined CP12 and boiler service visits are particularly economical. Thames Water and SES Water both serve parts of the borough on 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. Renewals are dated against your existing certificate so the rolling 12-month compliance cycle never slips.

Each gas appliance is visually inspected for damage and combustion staining, 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.

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.
