Gas Safety in Watford

Watford covers WD17, WD18, WD19, WD24, and WD25, taking in the town centre, Bushey Mill, Cassiobury, and Garston. Affinity Water (Veolia Central) supplies hard mains at around 280 ppm CaCO3 which makes scale management on combi heat exchangers a constant background pressure. Town-centre parking is restricted weekday daytime which means we plan engineer arrival around timed parking permits, and M25 J19 and J20 give direct access from the NW10 depot with target arrival 30 minutes. 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. 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.

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.
