Working in Feltham

In Feltham we cover TW4, TW13 and TW14; we also cover Ashford, 2.1 miles away, and Hounslow.

London homes in Feltham often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. We plan loft bathrooms in Feltham around the roof line, so the shower sits where you can stand and the eaves become storage. If your Feltham 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.

Water across much of Greater London is very hard. If your supply in Feltham 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

Fitted furniture made to the eaves, so the low space behind the slope becomes storage
A survey of the headroom across the room, with the usable height marked at each fitting position
A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
A check of your hot-water system and of the pressure and flow you actually get at loft level

Decisions to make first

Gravity or pumped waste

Gravity is silent and maintenance-free. A pumped waste or macerator lets fittings sit away from the stack, provided the house has a WC on gravity drainage elsewhere.

Roof window

A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.

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.

Who handles building control for a loft bathroom in Feltham?

Building control for Feltham 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 loft bathroom take?

Allow 6–12 working 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 Feltham.

Is the home survey in Feltham really free?

Yes. We visit, measure the room, check the pipework, drainage and electrics, and talk through what you want. You then get a written, itemised quote with no obligation to go ahead.

Electric shower or pumped shower in a loft?

An electric shower heats cold mains water as it flows, so it works in a loft whatever your hot-water system, but its flow is lower than a good pumped or mains-pressure mixer and it needs its own electrical circuit. A pumped mixer gives a stronger shower on a gravity system. See choosing a shower for the full comparison.
