Working in Swanley

As well as Swanley itself (BR8), we survey in Bexley, Dartford and Welling.

Swanley gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Swanley house has a combi boiler, a loft shower can usually run on mains pressure without a pump. We plan loft bathrooms in Swanley around the roof line, so the shower sits where you can stand and the eaves become storage.

Water across much of Kent is very hard. If your supply in Swanley 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 the floor joists where a bath or large shower tray will sit
Fitted furniture made to the eaves, so the low space behind the slope becomes storage
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

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.

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.

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 Swanley?

Building control for Swanley 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 Swanley.

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.
