Working in Castlereagh
We work right across Castlereagh — BT5, BT6 and BT7 — and in neighbouring Belfast and Newtownabbey.
Homes in and around Castlereagh vary, so we look at the floor, the walls and the water system before we price anything. Bathroom lighting in Castlereagh is wired to BS 7671 with RCD protection, tested, and certified when it is finished. We survey Castlereagh bathrooms before quoting lighting, so the zones are measured from your actual bath and shower.
Supplies across most of County Antrim are soft. That leaves you free to choose matt black, brushed brass or clear glass without worrying much about limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A lighting plan: number and position of downlights, mirror lighting, switches and any shaver socket
- RCD protection on the lighting circuit, checked at the consumer unit and added where it is missing
- A shaver supply unit where wanted, positioned away from direct spray
- A ceiling pull-cord or a switch outside the room, with separate switching for mirror and feature lights
Decisions to make first
Switching
A pull-cord inside, a switch outside the door or a motion sensor. Dimmers need LED fittings that are compatible with them.
Colour temperature
Warm white, around 3000 K, feels softer; cool white, around 4000 K, is crisper for shaving and make-up. Mixing the two in one room looks uneven.
Rules that apply in Northern Ireland
Northern Ireland has no Part P. Lighting work should follow BS 7671 as good practice, with the circuit tested and a certificate issued.
