What does bathroom underfloor heating cost in Didcot?
For Didcot, our guide range for bathroom underfloor heating is £800 to £2,800 including VAT. Prices in South East England run at about 12% above 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 Didcot
In Didcot we cover OX11; we also cover Abingdon, 4.6 miles away, and Cowley.
In Didcot, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Didcot home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below. We check door thresholds in Didcot homes at the survey, because underfloor heating and new tiles raise the floor slightly.
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
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- 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
- A floor sensor set between the heating runs and wired back to the thermostat
Decisions to make first
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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 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.
