What does bathroom underfloor heating cost in Slough?
Guide price in Slough: £800–£2,800 including VAT, depending on the room and what you choose. Prices in South East England run at about 12% above the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Slough
We cover every part of Slough, including SL1, SL2 and SL3, and nearby Windsor (1.8 miles) and Maidenhead (5.4 miles).
Slough has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. We check door thresholds in Slough homes at the survey, because underfloor heating and new tiles raise the floor slightly. If your Slough home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
Supplies across most of Berkshire are hard. 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 check of the floor construction, the room's heat loss and where the thermostat and supply will go
- A floor sensor set between the heating runs and wired back to the thermostat
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
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.
