What does bathroom underfloor heating cost in Briton Ferry?
In Briton Ferry, bathroom underfloor heating typically costs £650–£2,300 including VAT, based on Wales prices. Prices in Wales run at about 7% below the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Briton Ferry
We work right across Briton Ferry — SA7 and SA12 — and in neighbouring Neath and Clydach.
Homes in and around Briton Ferry vary, so we look at the floor, the walls and the water system before we price anything. We check door thresholds in Briton Ferry homes at the survey, because underfloor heating and new tiles raise the floor slightly. If your Briton Ferry home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
Water across much of West Glamorgan 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
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- 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
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
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.
Mat or loose cable
Mats are quickest on square, open floors. Loose cable is easier to route around awkward shapes, pipe boxing and a curved shower area.
Rules that apply in Wales
In Wales, the Welsh Part P also makes a new underfloor heating circuit notifiable, and it covers more bathroom electrical work than the English version. A registered electrician handles the notification.
