What does bathroom underfloor heating cost in Banbury?
In Banbury, bathroom underfloor heating typically costs £800–£2,800 including VAT, based on South East England prices. We adjust the national guide for South East England, where prices are typically about 12% above the UK average. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Banbury
We cover every part of Banbury, including OX16, and nearby Bicester (13.8 miles) and Daventry (15.4 miles).
Homes in and around Banbury vary, so we look at the floor, the walls and the water system before we price anything. Where a Banbury home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. For Banbury homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit.
Supplies across most of Oxfordshire are hard. Hard water leaves white marks on dark grout and gloss tiles, so matt finishes and stain-resistant grout are the practical choice. 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
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
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.
Floor finish
Tiles and stone pass heat through well. LVT and vinyl can work, but check the maximum floor temperature the flooring maker allows.
Rules that apply in England
In England, a new circuit for underfloor heating is notifiable under Part P, and so is connecting it to an existing circuit in a room with a bath or shower. The electrician either self-certifies through a competent person scheme or the work is notified to building control.
