Working in Ballymena

We work right across Ballymena — BT42, BT43 and BT44 — and in neighbouring Antrim and Magherafelt.

Homes in and around Ballymena vary, so we look at the floor, the walls and the water system before we price anything. Whether your Ballymena bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. If your Ballymena home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.

Water across much of County Antrim is soft. Soft water is kind to grout, so mid-tone and darker grouts stay looking fresh. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
A check of the floor construction, the room's heat loss and where the thermostat and supply will go

Decisions to make first

Thermostat

A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.

Insulation board thickness

Thicker boards warm up faster and lose less heat downwards, but raise the floor; the right choice depends on the door threshold and the next room.

Rules that apply in Northern Ireland

Northern Ireland has no Part P, but the heating circuit should be designed, tested and certified to BS 7671, with RCD protection. Building control is not usually involved unless drainage or structural work is being done alongside it.
