Working in Staines

In Staines we cover TW15, TW16, TW17 and 1 more postcode districts; we also cover Egham, 2 miles away, and Ashford.

In Staines, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Staines home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options. If your Staines house has a combi boiler, a loft shower can usually run on mains pressure without a pump.

Most of Surrey has hard water. If your supply in Staines 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 drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
A check of your hot-water system and of the pressure and flow you actually get at loft level
An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system

Decisions to make first

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.

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.

Is the home survey in Staines 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.
