Gas Safety & CP12 in Greenwich

Gas safety inspections in Greenwich span Georgian terraces in Greenwich and Blackheath, Edwardian villas across SE3 and SE9, post-war estates in Thamesmead, and the modern apartment stock along Greenwich Peninsula. The borough covers SE3, SE7, SE8, SE9, SE10, SE18, and SE28 including Woolwich, Eltham, Charlton, Deptford, and Kidbrooke. Thames Water serves the borough on moderately hard mains. The Greenwich and Blackheath conservation areas dictate period brassware and considered visible-pipework finishes on any follow-up carcassing work. 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, also called the CP12, is issued within 28 days of the check, and the tenant receives their copy inside the same 28-day window. Greenwich Peninsula new-build apartments sit on shared risers with their own pressure profile, and we test working pressure at the appliance against the data plate to surface any in-flat regulator issues early.

Each gas appliance is visually inspected for damage, combustion residue, and seal condition, working pressure is measured in kPa, gas tightness is verified using a calibrated digital manometer, flue flow is proven with smoke pellets for open-flue appliances and 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 20 pounds, the CP12 plus annual boiler service combination is 210 pounds at the same visit, and a second boiler at the same visit is 95 pounds.
