Working in Belfast

As well as Belfast itself (BT1, BT2, BT3 and 11 more postcode districts), we survey in Newtownabbey, Lisburn and Newtownards.

Belfast is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. For a loft bathroom in a tank-fed Belfast home, we work out how the shower will get its pressure before choosing a single fitting. If your Belfast loft shower is weak or the waste drains slowly, the fix is often in the pump or the pipe fall rather than the shower itself.

Supplies across most of County Antrim are soft. If that holds for your street in Belfast, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. 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
Fitted furniture made to the eaves, so the low space behind the slope becomes storage
A check of the floor joists where a bath or large shower tray will sit
A survey of the headroom across the room, with the usable height marked at each fitting position

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.

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 Northern Ireland

In Northern Ireland, building control covers the new drainage, any structural work to the floor and the ventilation, which is set out in Technical Booklet K. Wiring should be designed, tested and certified to BS 7671.

More about loft bathrooms

Loft bathrooms in Belfast: questions

How much does a loft bathroom cost in Belfast?

A loft bathroom in Belfast usually costs £5,700–£11,500 including VAT. Where you land in that range depends on the size of the room, whether the layout changes and the products you choose. After the free survey you get an itemised written quote, and the price is fixed in writing once the layout and products are agreed.

Do you cover BT1 in Belfast?

Yes. We cover all of Belfast, including BT1, BT2, BT3, BT4 and 10 more postcode districts, and nearby Newtownabbey, Lisburn and Newtownards. Survey visits are free and arranged at a time that suits you.

Is the water hard in Belfast?

Does a loft bathroom in Belfast need building control approval?

Building control in Belfast is run by the local district council. Where approval is needed, for example for new drainage, we tell you at the survey and handle it as part of the job.

Do I need a pump for a loft shower?

You need a pump if your hot water comes from a cylinder fed by a cold tank, because the tank usually sits at or below the height of a loft shower and gives almost no pressure. A combi boiler or unvented cylinder supplies mains pressure, so no pump is needed, though the flow can drop when other taps run. Shower pumps must only be used on gravity systems, never connected to the mains.
