Cylinder & Pump (G3) in Bromley
Cylinder, pump and unvented hot water system work covers installing or replacing a hot water storage cylinder, fitting a pump to boost pressure to showers or taps, and — where the system is unvented, meaning it's fed directly from the mains rather than a header tank — carrying out the installation and any subsequent work under G3 unvented hot water qualification, which is a legal requirement under the Building Regulations.
In Bromley, that covers Beckenham, Orpington, West Wickham, Chislehurst, Petts Wood, Hayes, Bickley. Bromley is one of the greenest London boroughs, with a historic High Street and residential areas ranging from Beckenham and Orpington's Victorian and interwar housing to the more rural character around Chislehurst and Hayes, close to the Kent border and within easy reach of our Sevenoaks and Tunbridge Wells teams.

Property styles in Bromley
Bromley's housing stock includes Victorian and Edwardian terraces and villas near the town centre and in Beckenham, substantial interwar detached and semi-detached houses across Orpington, Petts Wood and Bickley, and larger period properties around Chislehurst and Hayes, many on generous plots suited to rear and double-storey extensions.
Planning considerations
Bromley Council (London Borough of Bromley) is the local planning authority. Chislehurst and parts of Beckenham and Hayes are conservation areas, and much of the borough's southern and eastern edge is designated Metropolitan Green Belt, which restricts new buildings and substantial additions beyond normal permitted development limits.

FAQs
Cylinder & Pump (G3) in Bromley: FAQs
Do you provide cylinder & pump (g3) across all of Bromley?
Yes, we cover the BR1, BR2, BR3, BR4, BR5, BR6 and BR7 postcode areas in full, including Beckenham, Orpington, West Wickham, Chislehurst, Petts Wood, Hayes, Bickley.
What does G3 qualified mean and why does it matter?
G3 is the recognised qualification for working on unvented hot water systems, required under Building Regulations Part G because these systems store pressurised hot water and can fail dangerously if the safety devices aren't correctly installed or maintained. Always check an engineer's G3 qualification before unvented cylinder work is carried out.
Does an unvented cylinder need annual servicing?
Yes, and it's usually a condition of the manufacturer's warranty as well as good practice — the safety valves need checking annually by a G3-qualified engineer to confirm they're operating correctly.
