Shower repair in Richmond upon Thames: what you need to know
Types of shower
Electric showers heat water instantaneously from the cold mains and are independent of the boiler — common in rental properties (brands: Triton, Aqualisa, Mira). Mixer showers blend hot and cold water from the hot water system and require balanced hot and cold pressure. Power showers are mixers with an integrated pump. Digital showers use a remote controller with precise temperature control (brands: Aqualisa Quartz, Mira Vision). Each type has different fault patterns and repair procedures.
Common electric shower faults
No power: check the RCD, MCB, pull cord switch, and wiring connections inside the unit. No water flow: flow switch fault or inlet filter blocked with limescale (very common in London hard water areas). Water not heating: heating element failed or scaled. Temperature too hot or cold: thermostatic coil fault. Water dripping from head when off: non-return valve or solenoid valve fault. Shower trips the electrics: element failure or wiring fault.
Common thermostatic mixer faults
Poor temperature control: thermostatic cartridge failed — replacement cartridge typically £30 to £80 and a 30-minute repair. Low flow: cartridge restrictors, limescale in valve body, or pressure imbalance between hot and cold. Dripping from head: spindle O-rings or ceramic disc cartridge worn. Valve leaking externally: compression fitting or olive has failed. Shower tray drain slow: hair trap blockage or trapped waste under the shower tray.
Electric shower replacement
If the heating element has failed multiple times on a hard water area shower, full replacement is usually more cost-effective than repeated repairs. A new electric shower installation requires a dedicated 30A or 45A RCD-protected circuit — this is Part P notifiable work. Prestige Engineers are qualified for both plumbing and electrical work and can handle the full installation in a single visit.
Shower tray issues
A cracked shower tray must be replaced — it cannot be repaired reliably. A leaking shower tray seal (perished silicone) needs thorough cleaning of the old sealant before fresh silicone is applied — rushing this repair guarantees failure within months. A slow shower tray drain is usually a hair trap blockage cleared in minutes. Water leaking from a poorly sealed tray onto a timber floor causes rot that may not be visible for months.
Shower enclosure and door
A shower door that leaks onto the floor is usually a worn magnetic seal strip or wiper blade. These are inexpensive and a straightforward swap. A broken door hinge can usually be sourced as a spare part for most major brands. Cracked safety glass cannot be repaired — it must be replaced with a like-for-like toughened glass panel. Never use a shower with cracked safety glass — it can shatter unexpectedly under thermal stress.

Shower repair Richmond upon Thames: frequently asked
How much does shower repair cost in Richmond upon Thames?
Shower repair in Richmond upon Thames starts from £80 for an electric shower fault diagnosis and repair. Thermostatic cartridge replacement starts from £100. Electric shower element descale costs £80 to £150. Electric shower replacement (customer supplies unit) starts from £300. Full supply and fit of a new electric shower starts from £450. Shower tray resealing starts from £80.
Why does my electric shower keep tripping the electrics in Richmond upon Thames?
An electric shower that trips the RCD or MCB in Richmond upon Thames usually indicates a failed heating element or a wiring fault inside the shower unit. In London hard water areas, limescale builds up on the heating element and causes it to overheat and fail electrically, triggering the RCD. If the shower is over five years old and has never been descaled, element failure is the most common cause. A replacement element can restore function, but if the element has failed repeatedly, full shower replacement is usually more economical.
Can a thermostatic shower cartridge be replaced without replacing the whole valve in Richmond upon Thames?
Yes — in most cases a thermostatic shower cartridge can be replaced without removing or replacing the valve body. The cartridge slides out of the valve body after removing the handle and trim plate. A replacement cartridge for most major brands (Grohe, Hansgrohe, Aqualisa, Mira, Triton) costs £30 to £80 and the replacement takes 30 to 45 minutes. This restores full temperature control and eliminates dripping. Prestige Engineers carry common cartridge sizes or can source them quickly for Richmond upon Thames properties.
Why is my shower running cold in Richmond upon Thames?
A shower running cold in Richmond upon Thames has different causes depending on the shower type. An electric shower running cold indicates a failed heating element or a failed thermostatic coil — both are repairable parts. A mixer shower running cold usually indicates a failed thermostatic cartridge that can no longer maintain the set temperature, or a pressure imbalance between the hot and cold supplies that prevents the cartridge from mixing correctly. If the hot water supply to the shower is cold (check the hot tap at a basin), the problem is with the boiler or hot water system rather than the shower itself.
