Working in Grantham

As well as Grantham itself (NG31), we survey in Sleaford, Newark on Trent and Melton Mowbray.

Homes in and around Grantham vary, so we look at the floor, the walls and the water system before we price anything. If your Grantham house has a combi boiler, a loft shower can usually run on mains pressure without a pump. If your Grantham home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options.

Water across much of Lincolnshire is hard. If your supply in Grantham 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

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 your hot-water system and of the pressure and flow you actually get at loft level
A check of the floor joists where a bath or large shower tray will sit

Decisions to make first

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.

Where the shower goes

Under the ridge or in a dormer, where the full height is. A walk-in shower with a single panel is usually easier to fit to a roof line than a framed enclosure.

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.

Loft bathrooms in Grantham: questions

What is the price of a loft bathroom in Grantham?

Who handles building control for a loft bathroom in Grantham?

Building control for Grantham 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 Grantham.

Is the home survey in Grantham 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.
