Working in Warminster

We work right across Warminster — BA12 — and in neighbouring Westbury and Frome.

Warminster gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For Warminster homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. If your Warminster home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.

Most of Wiltshire has hard water. 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

The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
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 floor sensor set between the heating runs and wired back to the thermostat

Decisions to make first

Mat or loose cable

Mats are quickest on square, open floors. Loose cable is easier to route around awkward shapes, pipe boxing and a curved shower area.

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.

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.

Do I need an electrician to install bathroom underfloor heating?

Yes, for the connection. The fitter can lay the mat, but the supply, RCD protection and thermostat in a bathroom must be installed and tested by a qualified electrician, and in England and Wales the work is notifiable under Part P. Our underfloor heating guide covers the choices in more depth.
