    Installation, servicing and repair of unvented hot water cylinders, carried out by an engineer holding the G3 qualification.

    Unvented cylinder work for Chislehurst homes

    Chislehurst has a high proportion of larger detached and period homes, many with more than one bathroom, high hot water demand and unvented cylinders rather than combi boilers. Larger systems need correct sizing and regular servicing to keep pressure and hot water consistent across the house.

    Chislehurst sits minutes from Bromley, and we regularly work on larger family homes and multi-bathroom properties there.

    Whatever the property, the approach is the same: find the real cause, explain it in plain terms, and agree the price with you before any work starts. Chislehurst is part of our Bromley and South East London coverage.

    • G3 qualified for unvented hot water systems
    • Annual cylinder servicing and safety checks
    • Expansion vessels, valves and discharge pipework
    • Replacement cylinders sized to the property

    From £300

    Unvented Cylinder Installation & Servicing in Chislehurst: common questions

    Why does an unvented cylinder need servicing?

    Safety components such as the expansion vessel and relief valves wear over time. Annual servicing keeps the system safe and protects most warranties.

    Who is allowed to work on one?

    Unvented hot water work requires the G3 qualification, which we hold, so Chislehurst homeowners can have the cylinder serviced or replaced correctly and legally.

    My hot water pressure has dropped, is the cylinder at fault?

    It can be, though a failed expansion vessel or a partly closed valve is just as common. We test rather than guess.
