A shower that runs cold, dribbles, or leaks through the ceiling below is one of the most-reported faults in Wandsworth homes — and one of the most misdiagnosed. Our engineers fix the actual cause, from cartridge to pressure to seal.

Wandsworth water notes: Wandsworth's hard water works steadily on cylinders and shower valves — in a borough full of loft-extended family terraces, scaled unvented systems are a recurring theme. Wandsworth is the natural home of the extended Victorian terrace — Balham, Earlsfield and 'between the commons' houses with loft bathrooms and unvented cylinders — plus the vast new riverside stock at Nine Elms and Battersea. Mains supply here is managed by Thames Water.

Shower faults and their real causes

Running cold or scalding: a failed thermostatic cartridge, or on electric showers a failed heater can or solenoid. Dribbling flow: scale in the head or hose, a blocked inlet filter, or genuinely low supply pressure. Leaks below: the valve body, the waste trap, or the tray seal — established by isolation testing, not guesswork. Temperature swings: cartridge wear or supply imbalance. Each has a distinct fix, and most are same-visit repairs in Wandsworth.

Electric shower repair and replacement

Electric showers heat mains cold water on demand, so faults are electro-mechanical: heater cans, solenoid valves, pressure switches, thermal cut-outs. Where a unit is young and the part is available, repair is economic; where the can has failed on an older unit, replacement usually wins. Replacement must match or safely exceed the existing kW rating only if the cable and protective device support it — our Wandsworth engineers check the circuit before quoting a higher-rated unit, not after.

Fixing low pressure and weak flow

Weak flow has a hierarchy of causes: blocked head (free fix), scaled cartridge or filter (cheap fix), gravity-fed system limitations (pump or supply change), or shared-supply pressure loss at peak times (Thames Water network characteristics). Our Wandsworth engineers measure static and dynamic pressure at the outlet so the recommendation is based on numbers.

Shower work costs in Wandsworth

From £85 covers most Wandsworth shower repairs. Replacements are quoted by type: exposed mixer swaps and like-for-like electric units are quick, predictable jobs; concealed valves and full re-fits depend on access and finish, and are priced after inspection rather than guessed on the phone.

Frequently asked questions

Why is my shower pressure suddenly low?

Sudden loss usually means blockage — scale in the head, hose or inlet filter — or a failing cartridge. Gradual lifetime weakness on an upstairs shower usually means a gravity-fed system at its limits. The diagnosis determines whether the fix costs pounds or hundreds.

Is it worth repairing an electric shower?

If the unit is under ~5 years old and the failed part (solenoid, pressure switch) is available: usually yes. If the heater can has gone on an older unit: replacement is typically better value. We'll price both honestly.

What shower suits a low-pressure system?

Gravity-fed systems suit pumped showers or gravity-specific mixers; unvented and combi systems suit standard mains-pressure mixers. Fitting a mains-pressure shower on a gravity system is the most common cause of 'my new shower dribbles'.

Do you install digital and smart showers?

Yes — digital mixers and smart controllers are installed and repaired, with the control unit sited accessibly for future service. They're pressure-sensitive, so the system survey matters even more than with conventional mixers.
