What does bathroom underfloor heating cost in Ely?
In Ely, bathroom underfloor heating typically costs £750–£2,600 including VAT, based on East of England prices. We adjust the national guide for East of England, where prices are typically about 6% above the UK average. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Ely
As well as Ely itself (CB6 and CB7), we survey in Newmarket, March and St Ives.
Ely gets the same process as anywhere else: a free survey at your home and a written, itemised quote. Where a Ely home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. If your Ely home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
Most of Cambridgeshire has very hard water. 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
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- 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
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.
Floor heating and towel rail
Underfloor heating warms the room; a towel rail dries towels. Many bathrooms have both, and a dual-fuel rail keeps working in summer when the boiler is off.
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.
