Working in Rothesay
We cover all of Rothesay, including PA20. Because Rothesay is further afield, we arrange survey visits in batches; tell us your timescale and we will confirm a date before you commit to anything.
Rothesay gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Rothesay bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. Whether your Rothesay bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.
Supplies across most of Argyll and Bute are 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
- 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 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
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.
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.
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.
