Gas Safety in Mole Valley

Mole Valley covers Dorking, Leatherhead, Bookham, and Ashtead across RH4, RH5, KT22, KT23, and KT24. The district sits on the edge of the Surrey Hills Area of Outstanding Natural Beauty (AONB) which means conservation rules restrict external pipework and vent terminations on most properties. SES Water serves the north of the district and Sutton and East Surrey Water serves the south, both supplying very hard mains. Target dispatch time is 75 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. For AONB properties we coordinate route surveys for any follow-up BS 6891 carcassing where vent terminations need to comply with conservation rules.

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.
