Cylinder & Pump (G3) in Burgess Hill
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 Burgess Hill, that covers St Andrews, Gattons, Kings Way, Fairfield, Leylands, Victoria Park, Wivelsfield Green. Burgess Hill has expanded substantially since the Victorian era, with a historic core supplemented by significant 20th and 21st-century housing development, including several large newer estates on the town's edges. This mix means both period-property refurbishment and more straightforward extension work on modern housing are common locally.

Property styles in Burgess Hill
Victorian and Edwardian housing sits close to the town centre, with substantial areas of postwar and recent new-build estate housing across the wider town. Newer estate housing typically has more straightforward extension potential, subject to individual developer restrictive covenants which we advise clients to check.
Planning considerations
Mid Sussex District Council is the local planning authority. Some newer developments carry restrictive covenants set by the original developer that go beyond standard planning control — worth checking your title deeds alongside our planning assessment.

FAQs
Cylinder & Pump (G3) in Burgess Hill: FAQs
Do you provide cylinder & pump (g3) across all of Burgess Hill?
Yes, we cover the RH15 postcode area in full, including St Andrews, Gattons, Kings Way, Fairfield, Leylands, Victoria Park, Wivelsfield Green.
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.
Do new-build estates in Burgess Hill have restrictions on extending?
Some do, through developer-imposed restrictive covenants in addition to normal planning control. We recommend checking your title deeds, and we factor this into our feasibility advice where relevant.
