What does bathroom underfloor heating cost in March?
For March, our guide range for bathroom underfloor heating is £750 to £2,600 including VAT. Prices in East of England run at about 6% 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 March
We work right across March — PE15 — and in neighbouring Wisbech and Ely.
Being a smaller town does not change how we work in March: free survey, written quote, one team. Whether your March bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. For March homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit.
Water across much of Cambridgeshire is very 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
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- A floor sensor set between the heating runs and wired back to the thermostat
- 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
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.
Electric or wet
Electric is cheaper to install and quick to lay in one room. Wet costs more upfront but is usually cheaper to run where it is fed by a gas boiler or heat pump.
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.
