Working in Maidenhead
We work right across Maidenhead — SL6 — and in neighbouring Marlow and Slough.
Homes in and around Maidenhead vary, so we look at the floor, the walls and the water system before we price anything. For Maidenhead homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. We check door thresholds in Maidenhead homes at the survey, because underfloor heating and new tiles raise the floor slightly.
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
- For wet systems, pipes in low-profile boards or screed connected to a manifold or single-zone kit, with any boiler work done by a Gas Safe registered engineer
- 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
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
Decisions to make first
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.
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
