Being a smaller town does not change how we work in West Molesey: free survey, written quote, one team. We check door thresholds in West Molesey homes at the survey, because underfloor heating and new tiles raise the floor slightly. Whether your West Molesey bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.
Most of Surrey 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
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- 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
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.
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.
