Cylinder & Pump (G3) in Worthing
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 Worthing, that covers Tarring, Broadwater, Durrington, Goring-by-Sea, Findon Valley, Heene. Worthing is a seafront town with a strong Edwardian and interwar residential character, notable Art Deco buildings along the seafront, and a wide range of housing types stretching inland towards the South Downs.

FAQs
Cylinder & Pump (G3) in Worthing: FAQs
Do you provide cylinder & pump (g3) across all of Worthing?
Yes, we cover the BN11, BN12, BN13 and BN14 postcode areas in full, including Tarring, Broadwater, Durrington, Goring-by-Sea, Findon Valley, Heene.
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.
Are Worthing's seafront buildings protected?
Many of the town's notable Art Deco and Edwardian seafront buildings are listed or within conservation areas, which affects what external changes can be made without consent. We check this for individual properties.
