Working in Preston
In Preston we cover PR1 and PR2; we also cover Blackburn, 9.1 miles away, and Darwen.
Preston is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. Where a Preston home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. If your Preston 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 Lancashire 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
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- 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
Insulation board thickness
Thicker boards warm up faster and lose less heat downwards, but raise the floor; the right choice depends on the door threshold and the next room.
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.
