Working in Ewell
We cover every part of Ewell, including KT4, KT17 and KT19, and nearby Epsom (1.6 miles) and Sutton (2.1 miles).
In Ewell, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. For Ewell homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. We check door thresholds in Ewell homes at the survey, because underfloor heating and new tiles raise the floor slightly.
Water across much of Surrey is 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
- 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
- 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
Decisions to make first
Floor heating and towel rail
Underfloor heating warms the room; a towel rail dries towels. Many bathrooms have both, and a dual-fuel rail keeps working in summer when the boiler is off.
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.
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.
