Working in Hayes

In Hayes we cover UB3, UB4 and UB11; we also cover Southall, 2.3 miles away, and Heston.

In Hayes, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. We plan loft bathrooms in Hayes around the roof line, so the shower sits where you can stand and the eaves become storage. If your Hayes loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.

Supplies across most of Greater London are very hard. If your supply in Hayes 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

An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
A check of the floor joists where a bath or large shower tray will sit

Decisions to make first

Eaves storage

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

Getting the water pressure

A pumped shower suits a gravity system with a cold tank; an electric shower heats cold mains water at the point of use; a combi or unvented cylinder gives mains pressure throughout.

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.

Is the water hard in Hayes?

Who handles building control for a loft bathroom in Hayes?

Building control for Hayes 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.

Is a bath too heavy for a loft floor?

A standard acrylic bath is usually fine on a loft floor built for a conversion, but a filled bath with someone in it is heavy, and stone-resin or cast-iron baths are much heavier still. We check the joist size, span and direction at the survey, and a heavy bath may need a structural check and strengthening first.
