Working in Crowthorne
We cover every part of Crowthorne, including GU47, RG40 and RG45, and nearby Sandhurst (1.6 miles) and Yateley (2.5 miles).
Homes in and around Crowthorne vary, so we look at the floor, the walls and the water system before we price anything. If your Crowthorne home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below. If your Crowthorne 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 Berkshire 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
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- 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
- Bringing the system up to temperature gradually once the adhesive and grout have cured
Decisions to make first
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
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.
