Working in Swindon

In Swindon we cover SN1, SN2, SN3 and 1 more postcode districts; we also cover Calne, 12.7 miles away, and Cirencester.

Swindon is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. If your Swindon 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 Swindon homes at the survey, because underfloor heating and new tiles raise the floor slightly.

Water across much of Wiltshire is hard. Hard water leaves white marks on dark grout and gloss tiles, so matt finishes and stain-resistant grout are the practical choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
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

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.

Floor finish

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

Rules that apply in England

In England, a new circuit for underfloor heating is notifiable under Part P, and so is connecting it to an existing circuit in a room with a bath or shower. The electrician either self-certifies through a competent person scheme or the work is notified to building control.

Is the water hard in Swindon?

Who handles building control for bathroom underfloor heating in Swindon?

Building control for Swindon is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

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.
