What does bathroom underfloor heating cost in Stornoway?
In Stornoway, bathroom underfloor heating typically costs £650–£2,400 including VAT, based on Scotland prices. Prices in Scotland run at about 4% below the national guide, mainly because of labour rates. Travel and delivery to islands and remote areas are priced on your quote. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Stornoway
We cover all of Stornoway, including HS1. Because Stornoway is further afield, we arrange survey visits in batches; tell us your timescale and we will confirm a date before you commit to anything.
Stornoway gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Stornoway home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below. Whether your Stornoway 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 the Highlands and Islands 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
- A floor sensor set between the heating runs and wired back to the thermostat
- 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 check of the floor construction, the room's heat loss and where the thermostat and supply will go
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.
