Working in Antrim

In Antrim we cover BT29 and BT41; we also cover Ballymena, 10.4 miles away, and Newtownabbey.

Antrim gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Antrim bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. We check door thresholds in Antrim homes at the survey, because underfloor heating and new tiles raise the floor slightly.

Most of County Antrim is supplied with soft water. 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

For wet systems, pipes in low-profile boards or screed connected to a manifold or single-zone kit, with any boiler work done by a Gas Safe registered engineer
Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
A floor sensor set between the heating runs and wired back to the thermostat
Bringing the system up to temperature gradually once the adhesive and grout have cured

Decisions to make first

Floor finish

Tiles and stone pass heat through well. LVT and vinyl can work, but check the maximum floor temperature the flooring maker allows.

Electric or wet

Electric is cheaper to install and quick to lay in one room. Wet costs more upfront but is usually cheaper to run where it is fed by a gas boiler or heat pump.

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.

Is the home survey in Antrim really free?

Yes. We visit, measure the room, check the pipework, drainage and electrics, and talk through what you want. You then get a written, itemised quote with no obligation to go ahead.

Do you cover BT29 and BT41 in Antrim?

Yes. We cover all of Antrim, including BT29 and BT41, and nearby Ballymena, Newtownabbey and Belfast. Survey visits are free and arranged at a time that suits you.

Is electric underfloor heating expensive to run in a bathroom?

Running cost depends on the heated area, the insulation under the mat, how long it runs and your electricity tariff. As an example, a 150 W per m² mat covering 3 m² draws 450 W, so two hours a day uses about 0.9 kWh. A timer and floor sensor stop it running when nobody is using the room.
