What does bathroom underfloor heating cost in Dunoon?
For Dunoon, our guide range for bathroom underfloor heating is £650 to £2,400 including VAT. 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 Dunoon
In Dunoon we cover PA23; we also cover Greenock, 6.4 miles away, and Helensburgh. Because Dunoon is further afield, we arrange survey visits in batches; tell us your timescale and we will confirm a date before you commit to anything.
Being a smaller town does not change how we work in Dunoon: free survey, written quote, one team. Where a Dunoon home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. We check door thresholds in Dunoon homes at the survey, because underfloor heating and new tiles raise the floor slightly.
Water across much of Argyll and Bute 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
- 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
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.
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
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.
