Working in Kilwinning
As well as Kilwinning itself (KA13), we survey in Irvine, Kilmarnock and Ayr.
Kilwinning gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Kilwinning home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below. For Kilwinning homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit.
Water across much of Ayrshire 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.
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 floor sensor set between the heating runs and wired back to the thermostat
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
Decisions to make first
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.
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 Scotland
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.
