Local insights
Gas safety / CP12 in Windsor and Maidenhead: the local picture.
Windsor and Maidenhead covers Windsor town, Maidenhead, Ascot, Sunninghill, and Eton across SL4, SL5, and SL6. Crown Estate, Windsor Great Park, and Ascot Heath properties require managing-agent liaison for access. Thames Water supplies hard mains at around 270 ppm with legacy lead supply on the Royal Borough heritage stock that affects scope on follow-up pipework. Target dispatch time is 60 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 Crown Estate properties we always confirm engineer access via the managing agent ahead of dispatch.
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. Heritage-stock listed-building constraints feed into follow-up BS 6891 carcassing scope.
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.
