Working in Larne

We cover every part of Larne, including BT40, and nearby Carrickfergus (9.3 miles) and Newtownabbey (13.6 miles).

Being a smaller town does not change how we work in Larne: free survey, written quote, one team. Where a Larne home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. If your Larne home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.

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

Bringing the system up to temperature gradually once the adhesive and grout have cured
A check of the floor construction, the room's heat loss and where the thermostat and supply will go
Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician

Decisions to make first

Floor heating and towel rail

Underfloor heating warms the room; a towel rail dries towels. Many bathrooms have both, and a dual-fuel rail keeps working in summer when the boiler is off.

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.

More about underfloor heating

Underfloor heating in Larne: questions

What is the price of bathroom underfloor heating in Larne?

Bathroom underfloor heating in Larne usually costs £600–£2,200 including VAT. Where you land in that range depends on the size of the room, whether the layout changes and the products you choose. After the free survey you get an itemised written quote, and the price is fixed in writing once the layout and products are agreed.

Is the water hard in Larne?

Does bathroom underfloor heating in Larne need building control approval?

Building control in Larne 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 Larne.

Can underfloor heating go under a bath or shower tray?

No. Electric underfloor heating must not be laid under baths, shower trays, WCs or fixed furniture, because trapped heat can damage the cable and the item above it. It covers the open floor you stand on, and in a wet room it can run under the tiled shower area.
