Which towns do we cover in Fife?
Water across much of Fife is soft. Soft water is kind to grout, so mid-tone and darker grouts stay looking fresh. Hardness varies street by street, so check the figure for your postcode with your water supplier. Where a Dunfermline home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric.
What the job includes
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- A floor sensor set between the heating runs and wired back to the thermostat
- 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
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- 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
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.
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
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 Scotland
Electric underfloor heating in a bathroom must be on a circuit with 30 mA RCD protection under BS 7671, and the thermostat is positioned to suit the bathroom zones. There is no separate approval for the heating itself, but it should have its own thermostat and timer so it only runs when needed, and the electrical work must meet BS 7671 — in England and Wales it is notifiable as bathroom electrical work. Any work on a gas boiler for a wet system must be done by a Gas Safe registered engineer.
Scotland has no Part P. Underfloor heating added during a straight bathroom refit rarely needs a building warrant on its own, but it must be installed, tested and certified to BS 7671 with RCD protection.
