Working in Penzance

As well as Penzance itself (TR18), we survey in Camborne, Redruth and Falmouth.

Penzance gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For Penzance homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. Whether your Penzance bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.

Most of Cornwall 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

A check of the floor construction, the room's heat loss and where the thermostat and supply will go
The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
A floor sensor set between the heating runs and wired back to the thermostat

Decisions to make first

Floor finish

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

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 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.
