London showers face two big challenges: hard water and awkward hot water systems. Scale clogs heads, hoses and thermostatic cartridges, and many period homes still have a loft tank only a short distance above the shower – or, in flats, a small cylinder or combi that struggles when two taps run at once.
Whether you want a new shower fitted, an old one repaired or a pump that actually works, you can describe your set-up and compare quotes from London plumbers.
Loft bathrooms, limescale and pressure
Loft conversions often put the new shower above the cold water tank, so gravity alone can't feed it. A negative-head pump or a change to an unvented cylinder may be needed. In flats, mains pressure can vary from floor to floor, and a plumber will check flow before recommending a shower.
Limescale is the other constant. Thermostatic cartridges that stick, electric showers that lose temperature and heads that spray sideways are all common in London. Servicing or replacing parts, and in some cases a water softener, keeps showers working.
Converting a bath into a walk-in shower is popular in London's smaller bathrooms, but the waste needs enough fall to the stack, and in flats the lease may say what you can change. Some newer blocks have unvented cylinders, which give strong mains-pressure showers but must be serviced by a qualified installer – so ask about that qualification if your shower problem turns out to be the cylinder.

Information that helps a plumber quote
- A photo of your boiler and, if you have one, the hot water cylinder and loft tank.
- A photo of the current shower, the valve and anything written on the unit.
- Whether the shower is over a bath, in an enclosure or a walk-in, and which floor it's on.
- What's wrong now – weak flow, temperature swings, leaks or noise – and when it started.
Water supply in London
Most of London's water comes from the Thames and Lea and the chalk beneath the city, so it is hard. Limescale builds up in kettles, shower heads, thermostatic valves and combi boiler heat exchangers, and plumbers here are regularly asked to descale or replace parts, or to fit a water softener. The capital also has a huge stock of pre-war homes where old lead or iron supply pipes, shared supplies and tired stopcocks still turn up.

Plumbers taking on shower installation and repair work in London often also cover:
Shower plumbing in London: common questions
Why is my London loft shower so weak?
If it's above your cold water tank, gravity can't push water up to it. A negative-head pump, or switching to a mains-pressure system, is usually the answer.
How often should a thermostatic shower be serviced in London?
In hard water areas, servicing every year or two helps. Replace the cartridge if it sticks or won't hold temperature.
Can I fit a power shower in my flat?
Only if you have a gravity-fed system with a tank. With a combi or mains-pressure supply, choose a mixer shower instead.
