Working in Sevenoaks

We cover every part of Sevenoaks, including TN13, and nearby Tonbridge (6.5 miles) and Swanley (8.6 miles).

In Sevenoaks, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Sevenoaks house has a combi boiler, a loft shower can usually run on mains pressure without a pump. We plan loft bathrooms in Sevenoaks 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 Sevenoaks 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 shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
Fitted furniture made to the eaves, so the low space behind the slope becomes storage
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

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.

Bath or no bath

A bath under the slope makes good use of low space, but the floor has to carry it when it is full of water and someone is in it.

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 Sevenoaks?

Building control for Sevenoaks 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 Sevenoaks.

How do you ventilate a loft bathroom?

A loft bathroom fan is usually ducted through the roof to a tile or slate vent, or out through a gable wall. The duct should be insulated where it crosses a cold space, so condensation does not run back into the fan. A roof window helps with daylight and airing but does not replace the fan.
