Working in Belfast
In Belfast we cover BT1, BT2, BT3 and 11 more postcode districts; we also cover Newtownabbey, 4.4 miles away, and Lisburn.
In a city the size of Belfast, parking and access for a skip are worth sorting before the start date — we will ask at the survey. We survey cloakrooms in Belfast with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly. If your Belfast cloakroom has no window, we size and duct the extractor fan so the room clears properly.
Most of County Antrim is supplied with soft water. In soft water, taps, wastes and toilet pans scale up slowly, so brushed and matt finishes are a safe choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A concealed cistern frame or WC unit where the space allows
- Splashback or feature tiling and a new floor, often LVT or porcelain
- Lighting wired by a qualified electrician, tested and certified
- An extractor fan ducted to outside, wired with an overrun timer or linked to the light
Decisions to make first
Under-stair layout
Headroom drops quickly under stairs. The basin and the space in front of the WC need standing height; the low end of the room can take the cistern or storage.
Macerator or gravity
Gravity drainage is silent and needs no maintenance. A macerator lets a WC go where a pipe could not otherwise fall, provided another WC in the house is on gravity drainage.
Rules that apply in Northern Ireland
In Northern Ireland, building control covers new drainage and ventilation, with ventilation set out in Technical Booklet K. The Water Supply (Water Fittings) Regulations (Northern Ireland) 2009 limit a new WC to a 6-litre flush.
