Gas Safety in Hertsmere

Hertsmere covers Borehamwood, Bushey, Potters Bar, and Radlett across WD6, WD7, WD23, and EN5. Affordable Water (now Affinity Water) supplies hard mains at around 280 ppm, and legacy lead supply on pre-1970s stock is common, particularly in older Bushey village pockets. The Borehamwood studios estates and Bushey village access patterns favour off-peak callouts, and M25 J23 plus A1(M) J1 both serve the area for our 32-minute target dispatch from NW10. 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. For property portfolios across Borehamwood and Bushey we will price multi-property visits on a portfolio basis with weekday-daytime scheduling to bring drive time down.

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 against the dwelling's habitable volume.

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.
