Hot water cylinder repair and replacement
Vented and unvented cylinders store hot water for homes without combi boilers. Faults include dripping from valves, lukewarm water, noise and complete loss of hot water.
Important credential note
Unvented (G3) cylinders require appropriately qualified engineers for certain work. We route those jobs to partners with the right credential rather than improvising.

Diagnose coil, immersion, motorised valves or cylinder leaks; isolate safely; repair or quote replacement with clear scope for discharge pipework and controls. Immersion-only faults may sit under immersion heater pages.

Vented versus unvented
Vented cylinders rely on loft tanks; unvented use mains pressure with safety controls. Advice and parts differ completely — we identify the type before quoting.
Legionella awareness
Stored water systems in rentals may fall under wider risk assessment duties for landlords. We can replace or service immersions and thermostats as plumbing work; formal legionella risk assessments are a broader compliance topic.
Noise and air
Kettling often means scale on the element or coil. That can justify descaling, element replacement or cylinder renewal depending on age.
