Working in Windsor

We work right across Windsor — SL4 — and in neighbouring Slough and Egham.

In Windsor, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If you are replacing a failed electric shower in Windsor, we check whether the existing cable and circuit suit the new unit. If the shower in your Windsor home swings between hot and cold, a thermostatic valve is usually the fix.

Supplies across most of Berkshire are hard. If your supply in Windsor is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

A check of your hot-water system, water pressure and flow rate
New pipework and isolation valves, plus a pump only where the system is gravity-fed from a cold tank
Tiling or re-tiling around the shower, with tanking behind new tiles in the wet area
Removal of the old shower, a full-flow test and a handover on isolating and descaling it

Decisions to make first

Exposed or concealed

An exposed bar valve fixes onto the tiles and is easy to service. A concealed valve sits in the wall for a cleaner look but needs careful setting-out and a plan for access.

Power shower

A mixer with a built-in pump, for tank-fed systems only. It lifts a weak gravity shower but must never be connected to the mains.

Rules that apply in England

In England, an electric shower usually needs its own dedicated circuit, often 40 to 45 amps for an 8.5 to 10.5 kW unit, and a new circuit is notifiable under Part P. The Part G limit of 48 °C applies to a new bath in a new dwelling or one created by change of use, not to a shower, but a thermostatic valve gives similar protection. An unvented cylinder fitted to improve the shower must be installed by a G3-qualified installer.

Is the water hard in Windsor?

Who handles building control for a new shower in Windsor?

Building control for Windsor is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

How long does a new shower take?

Allow half a day to 3 days on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Windsor.

Does an electric shower need its own circuit?

Almost always. An electric shower draws a large current, so it needs a dedicated circuit from the consumer unit, often 40 to 45 amps for an 8.5 to 10.5 kW unit, with RCD protection. In England and Wales a new circuit is notifiable work. Swapping like for like onto an adequate existing circuit is simpler.
