Diagnose Your Shower Fault
Find your symptom below. Each card includes a quick DIY check to try before calling us, and the expected repair cost. The 🚨 card is urgent — act immediately.
Low Shower Pressure
Likely cause: Limescale-blocked head, failing pump, or closed isolating valve
DIY check: Unscrew the shower head and soak in white vinegar overnight — resolves limescale blockage
Descale (DIY) · Pump repair £120–£180 · Pump replacement £200–£350
Hot Then Cold — Temperature Fluctuating
Likely cause: Failing thermostatic cartridge, boiler pressure drop, or another appliance drawing cold
DIY check: Check boiler pressure (should be 1–1.5 bar). Run shower with no other taps — if it steadies, it's a pressure issue
Thermostatic cartridge replacement £95–£140
No Hot Water in Shower
Likely cause: Failed cartridge, boiler fault, or shower diverter stuck on cold
DIY check: Check hot water at the basin tap — if none there either, it's a boiler or hot water issue, not the shower
Cartridge replacement £95–£140 · Diverter valve repair £85–£110
Leaking Through Ceiling Below
Likely cause: Failed tray seal, cracked tray, or loose waste connection
DIY check: Stop using the shower immediately. Place towels. Call us same day — water in ceilings causes structural damage fast
Re-seal tray £85–£130 · Waste re-connection £75–£110 · Tray replacement £250+
Noisy Shower Pump
Likely cause: Air in pump, worn bearings, or pump running dry
DIY check: Check pump is fully primed with water — an airlock makes a rattling noise. Turn off and re-prime
Pump service/bleed £85 · Pump replacement £200–£350
Dripping Shower Head When Off
Likely cause: Cartridge or ceramic disc not sealing fully
DIY check: Tighten the shower head fitting first. If still dripping, the cartridge has failed
Cartridge replacement £95–£140

Shower Repair FAQs
How much does shower repair cost in London?
Shower repair in London costs £85–£250 depending on the fault. A thermostatic cartridge replacement is £95–£140. A shower pump repair is £120–£180, or £200–£350 for replacement. Re-sealing a leaking shower tray is £85–£130. Electric shower replacement is £180–£280 like-for-like. Fixed quote before starting.
Why has my shower lost pressure?
Low shower pressure in London is usually caused by a limescale-blocked shower head (very common in London's hard water), a failing shower pump on a gravity-fed system, a partially closed isolating valve, or a blocked thermostatic cartridge. Start by descaling the shower head in white vinegar overnight. If pressure is still poor, call us.
Why does my shower run hot then cold?
Temperature fluctuation is usually a failing thermostatic cartridge, boiler pressure dropping, or another tap pulling cold water. Thermostatic cartridge replacement is the most common fix — £95–£140 including parts.
My shower is leaking through the ceiling below — what should I do?
Turn off the shower immediately. Water tracking through structural materials causes significant damage. The most common causes are: failed silicone seal between tray and wall tiles, a cracked shower tray, or a leaking waste connection. Call us for same-day diagnosis.
Can you repair an electric shower?
Yes, for some faults. A fluctuating temperature from an electric shower is often a failing heating element or solenoid valve (£95–£150 to repair). If the PCB has failed or the unit is over 10 years old, replacement is usually more cost-effective. We assess on arrival and give an honest recommendation.
Why is my shower head dripping after the shower is turned off?
A dripping shower head after shutoff means the valve cartridge or diverter valve isn't sealing fully. In thermostatic showers it's usually the thermostatic or volume cartridge. In mixer showers it's often the ceramic disc or O-ring. Cartridge replacement resolves this — £95–£140 including parts.
