What does an en-suite cost in Larne?

In Larne, an en-suite typically costs £4,000–£7,900 including VAT, based on Northern Ireland prices. Prices in Northern Ireland run at about 12% below the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Larne

As well as Larne itself (BT40), we survey in Carrickfergus, Newtownabbey and Bangor.

Larne gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We quote new en-suites in Larne only after checking the drainage route on site, so the price reflects the work your house actually needs. If your Larne home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue.

Supplies across most of County Antrim are soft. If that holds for your street in Larne, 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

A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear

Decisions to make first

Noise

Acoustic insulation in the stud walls and a quiet fan make a real difference when one of you showers early while the other is still asleep.

Shower size

A 900 mm square tray is a comfortable minimum for an enclosure. In a long, narrow room, a 1200 by 800 mm walk-in tray with one glass panel feels far more generous.

Rules that apply in Northern Ireland

In Northern Ireland, building control covers the new drainage and ventilation for an en-suite, with ventilation set out in Technical Booklet K. There is no Part P, but the wiring should still be designed, tested and certified to BS 7671.

More about en-suites

En-suites in Larne: questions

How much does an en-suite cost in Larne?

An en-suite in Larne usually costs £4,000–£7,900 including VAT. Room size, layout changes and your choice of products move the figure within that range. The free survey gives you an itemised quote, fixed in writing once the details are agreed.

Is the water hard in Larne?

Does an en-suite in Larne need building control approval?

Building control in Larne 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.

How long does an en-suite take?

Allow 4–8 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 Larne.

Can you put an en-suite anywhere?

Almost anywhere the waste can reach the soil stack. Gravity drainage needs a steady fall in the pipe, so the further the en-suite is from the stack, the more depth you need under the floor or behind boxing. Where that is not possible, a pumped waste or macerator can be used if the home already has a WC on gravity drainage. Our guide to adding an en-suite covers this in more detail.
