Shower Repair & Installation in Southwark
Southwark shares the capital's hard water, and scale shows up early in the borough's hard-worked conversions and new-build blocks alike — descaling and inhibitor fits are routine here. Shower heads, cartridges and electric shower heater cans in Southwark feel that first — flow drops, temperature wanders, and units fail early without descaling. Most of it is recoverable.
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 Southwark.
Electric shower repair and replacement
We repair electric showers where parts economics make sense and replace them where they don't — with one hard rule: a higher-kW unit is only fitted when the existing circuit, isolator and RCD protection are verified suitable. Undersized cabling behind a powerful new shower is a fire risk, and no Southwark install through this network cuts that corner.
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 Southwark engineers measure static and dynamic pressure at the outlet so the recommendation is based on numbers.
Shower work costs in Southwark
From £85 covers most Southwark 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.
Can I have a more powerful electric shower fitted?
Only if the existing circuit supports it — cable size, isolator and RCD protection are checked first. A 10.5kW shower on cabling sized for 8.5kW is dangerous, and any quote that skips that check should worry you.
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.
Why does my shower go cold when someone runs a tap?
On mixer showers, a worn thermostatic cartridge can no longer compensate for supply changes; on combi-fed systems, the boiler's flow priority is the culprit. A cartridge replacement fixes the former; flow regulation helps the latter.
