Working in Alton

As well as Alton itself (GU34), we survey in Bordon, Farnham and Basingstoke.

Alton gets the same process as anywhere else: a free survey at your home and a written, itemised quote. Where a Alton home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. If your Alton bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer.

Most of Hampshire 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

Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
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
The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit

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.

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.

Is the water hard in Alton?

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.
