Working in Devizes

In Devizes we cover SN10; we also cover Calne, 6.1 miles away, and Melksham.

Being a smaller town does not change how we work in Devizes: free survey, written quote, one team. For Devizes homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. We check door thresholds in Devizes homes at the survey, because underfloor heating and new tiles raise the floor slightly.

Supplies across most of Wiltshire are 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

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
Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
A floor sensor set between the heating runs and wired back to the thermostat

Decisions to make first

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.

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 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.

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.
