Working in Limavady

We work right across Limavady — BT49 — and in neighbouring Coleraine and Derry.

Being a smaller town does not change how we work in Limavady: free survey, written quote, one team. For Limavady homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. Whether your Limavady bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.

Most of County Londonderry 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

Bringing the system up to temperature gradually once the adhesive and grout have cured
A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
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

Decisions to make first

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.

Thermostat

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

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.

Does bathroom underfloor heating in Limavady need building control approval?

Building control in Limavady is run by the local district council. Where approval is needed, for example for new drainage, we tell you at the survey and handle it as part of the job.

How long does bathroom underfloor heating take?

Allow 1–2 working days (added to a fit) on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Limavady.

Yes, a little. An electric mat on an insulation board usually adds roughly 10 mm before the adhesive and tile, which matters at the door threshold. Wet systems in low-profile boards add more, and screeded systems more again.
