Working in Haywards Heath
In Haywards Heath we cover RH16; we also cover Burgess Hill, 3 miles away, and Crawley.
Homes in and around Haywards Heath vary, so we look at the floor, the walls and the water system before we price anything. We check door thresholds in Haywards Heath homes at the survey, because underfloor heating and new tiles raise the floor slightly. Whether your Haywards Heath bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.
Water across much of West Sussex 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
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- A floor sensor set between the heating runs and wired back to the thermostat
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
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.
Mat or loose cable
Mats are quickest on square, open floors. Loose cable is easier to route around awkward shapes, pipe boxing and a curved shower area.
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.
