Working in Hounslow

In Hounslow we cover TW3, TW4, TW5 and 5 more postcode districts; we also cover Isleworth, 0.9 miles away, and Heston.

In Hounslow, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If your Hounslow loft shower is weak or the waste drains slowly, the fix is often in the pump or the pipe fall rather than the shower itself. We plan loft bathrooms in Hounslow around the roof line, so the shower sits where you can stand and the eaves become storage.

Supplies across most of Greater London are very hard. If your supply in Hounslow 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 and of the pressure and flow you actually get at loft level
Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
Fitted furniture made to the eaves, so the low space behind the slope becomes storage

Decisions to make first

Where the shower goes

Under the ridge or in a dormer, where the full height is. A walk-in shower with a single panel is usually easier to fit to a roof line than a framed enclosure.

Eaves storage

Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.

Rules that apply in England

In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.

Loft bathrooms in Hounslow: questions

What is the price of a loft bathroom in Hounslow?

Is the water hard in Hounslow?

Who handles building control for a loft bathroom in Hounslow?

Building control for Hounslow 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.

Do I need a pump for a loft shower?

You need a pump if your hot water comes from a cylinder fed by a cold tank, because the tank usually sits at or below the height of a loft shower and gives almost no pressure. A combi boiler or unvented cylinder supplies mains pressure, so no pump is needed, though the flow can drop when other taps run. Shower pumps must only be used on gravity systems, never connected to the mains.
