Gas Safety in Spelthorne

Spelthorne covers Staines-upon-Thames, Sunbury-on-Thames, Ashford, and Shepperton across TW15, TW16, TW17, TW18, and TW19. The district sits inside the Heathrow noise corridor which means some properties have noise-buffered roof voids that complicate vent flue runs and require careful flow testing at certification. Affinity Water Central supplies moderately hard mains at around 270 ppm. Target dispatch time is 50 minutes from the NW10 depot. 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 whether the property sits inside or outside the M25 envelope. 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. New tenants must have a copy before they take occupation of the property.

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. Noise-buffered roof voids get particular attention on flue route certification.

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.
