Shower Pump London
Noisy, weak, or failed shower pump? We repair and install all makes of shower pump across London same day — from £65, no call-out fee, anti-vibration mounts and flexible hoses included.
🚿 Have a combi boiler? You don't need a shower pump.
Shower pumps are only for gravity-fed (vented) hot water systems with a cold water tank in the loft. If you have a combi boiler, your hot water comes from the mains at mains pressure. Call us to diagnose low shower pressure on a combi — the cause and fix are completely different.

Diagnose Your Shower Pump Problem

| Pump doesn't start when shower turned on | Failed flow switch (limescale contacts), air lock, electrical fault | Flow switch replacement £65–£120; air bleed (free); check fuse |
| Pump starts then cuts out | Thermal cut-out triggered by overheating (scale-blocked impeller), low water supply from tank | Descale or replace pump; check tank supply float valve |
| Loud grinding / rattling noise | Limescale on impeller, worn bearing, loose mounting | Pump replacement (common after 6–8 yrs London hard water); anti-vib pads £25 |
| Pump runs but no pressure improvement | Impeller seized with scale, pump too small for system head | Pump replacement; assess head height to size correctly |
| Vibration / noise through floor / walls | Rigid pipework connections transmitting pump vibration | Fit flexible hose connectors (included in our installation standard) £25–£50 |
| Pressure surges then drops in shower | Air in system, float valve in cold tank failing, pump too large for head | Bleed air; replace float valve £65–£120; pump reassessment |

Shower Pump FAQs
Why has my shower pump stopped working in London?
Most common cause: limescale blockage from London's hard water (280–320 mg/l) — calcium deposits on the impeller and flow switch stop the pump triggering or turning. Also: air lock (bleed by opening supplies), failed flow switch, or burned motor. Pumps over 7 years old in London's hard water are usually more economical to replace than repair.
Why is my shower pump so noisy in London?
Almost always limescale on the impeller forcing the motor to work harder. Also: loose mounting (fit anti-vibration pads) or rigid pipe connections (fit flexible hoses). Both are included in our standard installation. Pumps over 7–8 years old in London's hard water: replace rather than repair.
What type of shower pump do I need for my London home?
Twin impeller pump for showers (boosts hot and cold equally — prevents temperature fluctuation). 2.0 bar for most London gravity-fed systems. Stainless steel impeller for hard water resistance. Our top picks: Stuart Turner Monsoon, Grundfos STP, Salamander CT Xtra.
Can I fit a shower pump if I have a combi boiler?
No. Shower pumps only work with gravity-fed vented hot water systems (cylinder fed from loft tank). Combi boilers supply mains pressure hot water — no pump needed or compatible. Low shower pressure on a combi has different causes (blocked head, mains supply). Call us to diagnose before buying a pump.
How long does a shower pump last in London?
10–15 years in soft water areas. In London's hard water (280–320 mg/l): 6–10 years. Extend life with: scale inhibitor on cold feed, annual descale, isolation valves for maintenance access, never run dry. Our installations include all of these as standard.
How much does a shower pump cost to install in London?
£350–£600 installed including pump, flexible hoses, anti-vibration mounts. Entry-level twin 2.0 bar: £350–£420. Stuart Turner Monsoon 2.0 bar: £420–£520. Grundfos STP 3.0 bar: £500–£600. Like-for-like replacement: £300–£450. Repair (flow switch/capacitor): £95–£180.
