Working in Antrim
We cover every part of Antrim, including BT29 and BT41, and nearby Ballymena (10.4 miles) and Newtownabbey (12.7 miles).
Being a smaller town does not change how we work in Antrim: free survey, written quote, one team. We quote new en-suites in Antrim only after checking the drainage route on site, so the price reflects the work your house actually needs. If you live in a Antrim flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents.
Water across much of County Antrim is soft. If that holds for your street in Antrim, 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
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
Decisions to make first
Door type
An outward-opening door frees floor space inside. A sliding pocket door saves space on both sides but needs a stud wall long enough to take the cassette.
Night lighting
A mirror light or low-level LED strip on its own switch lets you use the en-suite at night without the full glare of the ceiling lights.
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.
