How much does it cost to install electric underfloor heating?
Published UK costs for fitted electric underfloor heating per m² and per room, what a full job including floor work and the electrician costs, what changes a quote, the kit you need and running costs.
Short answer: UK cost guides put fitted electric underfloor heating at about £40 to £90 per m² for the heating system itself, which is roughly £240 to £300 for a 4m² en-suite or £600 to £900 for a 12m² kitchen (published UK cost guides, October 2026). Once you add insulation boards, levelling, the electrician's connection and new tiles, a small bathroom is more like £600 to £1200. Quotes vary a lot with the floor, the room and where you live, so get at least two quotes that list what is included.
"How much does it cost?" has two answers for electric underfloor heating. The heating mat, thermostat and fitting are fairly cheap. The floor around it, lifting the old floor, levelling, insulating, tiling and the electrician, is often most of the bill. That is why one quote for a bathroom can be a few hundred pounds and another well over a thousand.
This guide sets out published UK cost ranges, what each part of the job costs, what changes the price and which kit you need. MaxHeatUFH supplies the kit and does not install, but it can pass your job to a vetted approved installer. For wet systems and whole-house costs, see our underfloor heating cost guide.
How much does electric underfloor heating cost per m² fitted?
About £40 to £90 per m² for supply and fit of the heating, according to one published UK cost guide (October 2026), based on quotes from tradespeople. It gives £40 to £80 per m² in a new build and £50 to £90 in an older home, where floors need more preparation. Smaller rooms cost more per m² because the fixed costs, such as the thermostat and the electrician's visit, are spread over less floor.
| Room | Size | Typical cost, supply and fit |
|---|---|---|
| Downstairs toilet | 2m² | £160 to £180 |
| En-suite bathroom | 4m² | £240 to £300 |
| Medium kitchen | 12m² | £600 to £900 |
| Conservatory | 14m² | £630 to £980 |
| Living room | 20m² | £800 to £1200 |
These figures are for the heating system. They do not include a new floor finish, and they assume a floor that is ready to take the mat.
What does a full electric underfloor heating job cost?
More, once the floor work is included. Another published 2026 cost guide puts a small bathroom (3 to 5m²) at £600 to £1200 and a medium kitchen (10 to 15m²) at £1500 to £3000, including insulation, levelling, the electrician and tiling. It breaks a 10m² tiled kitchen down like this:
| Item | Cost for 10m² kitchen |
|---|---|
| Heating mat system | £400 to £600 |
| Insulation boards | £150 to £250 |
| Adhesive and levelling compound | £100 to £200 |
| Thermostat | £100 to £200 |
| Installation labour | £300 to £500 |
| Electrician | £200 to £300 |
| Tiling | £500 to £800 |
| Total | £1750 to £2850 |
The same guide gives an electrician's connection at £150 to £350, electrician day rates of £250 to £400, and tilers at £180 to £300 a day (up to £350 in London). It says London and the South East are roughly 15 to 30% higher than northern or rural areas. Individual quotes vary widely: on one online question about a bathroom, tradespeople gave figures from about £450 for labour to around £700 including backer board.
Why do electric underfloor heating quotes vary so much?
Because the floor, not the mat, sets most of the price. The main things that move a quote are:
- The existing floor: lifting old tiles, a new screed or a ply overlay all add cost. Published cost guides give about £430 for screeding an average room.
- Insulation: boards under the mat cut heat loss into a concrete slab and speed up warm-up, but add material and time. Our guide to insulation boards for electric UFH explains when you need them.
- New build or retrofit: retrofits cost more because floors need preparing.
- Access and room shape: lots of fixtures, or work upstairs, takes longer.
- The electrical supply: Cost guides note that systems drawing over 13A need a dedicated circuit, and a consumer unit replacement is around £525.
- Controls: a smart thermostat costs more than a simple programmable one, and each extra zone adds a thermostat and wiring.
- Location: labour rates are higher in London and the South East.
What kit do I need?
For a typical small room, the heating kit itself is a modest part of the bill. The MaxHeatUFH kit for electric floor heating:
- Electric heating mat 100W/m²
- Electric heating mat 150W/m² or 200W/m²
- Loose heating cable
- Heatmiser Slimline-E thermostat
- Heatmiser neoStat-e smart thermostat
- Cement-coated XPS tile backer board (1200 x 600mm)
- Uncoupling membrane (1m wide roll)
Mats come in a range of sizes. See the 150W/m² heating mat for the full size list, and our guide to mat sizes to work out which you need. MaxHeatUFH delivers next working day across the UK on orders placed by 12pm Monday to Friday, offers 30-day returns, and has trade accounts with trade prices.

Can I save money by fitting it myself?
You can lay the mat yourself, but not the final connection. A qualified electrician must connect the mat and thermostat to the supply, to BS 7671, with 30mA RCD protection. In England, a new circuit, or adding to a circuit around a bath or shower, is notifiable under Part P of the Building Regulations. A registered electrician can self-certify it; otherwise building control or a registered third-party certifier must inspect it, which adds cost.
Many people lay the mat and tile the floor, then book an electrician for the connection, which published cost guides put at £150 to £350. Test the mat before, during and after tiling, so you do not tile over a damaged cable. Our guide on whether you can install underfloor heating yourself covers what is and is not DIY.
How long does installation take?
About one to two days for a single room, according to published cost guides. One says a mat can often be laid in a day, but a bathroom with tiling takes two to four days, and the adhesive or levelling compound needs to cure before the heating is switched on. Follow the curing time in the adhesive maker's instructions. See our guide to how long underfloor heating takes to install.
What will it cost to run?
Each m² of 150W/m² mat uses 0.15kWh per hour while it is heating. At the October 2026 price cap of 26.32p per kWh for electricity, a 4m² bathroom mat (600W) costs about 15.8p an hour at full output, and a 12m² kitchen at 150W/m² (1.8kW) about 47.4p an hour. The thermostat switches the mat on and off, so real costs depend on how long it runs. Our running cost per m² guide works through this in detail.
If you would like your job fitted, MaxHeatUFH can pass it to a vetted approved installer. Send your details through the installation enquiry form or email sales@maxheatufh.com.
Frequently asked questions
How much does it cost to put electric underfloor heating in a bathroom?
Published UK cost guides give £240 to £300 for the heating in a 4m² en-suite. With insulation, levelling, the electrician and new tiles, one guide puts a 3 to 5m² bathroom at £600 to £1200.
Is electric underfloor heating cheaper to install than water?
Usually, in a single room. Published cost guides say electric is generally cheaper to install than wet systems, though it costs more per kWh to run. See our water vs electric guide for the trade-offs.
How much does an electrician charge to connect underfloor heating?
Published cost guides give £150 to £350 for the connection. The price rises if a new circuit or consumer unit work is needed.
Do I need building regulations approval for electric underfloor heating?
A new circuit, or adding to a circuit around a bath or shower, is notifiable under Part P in England. A registered electrician can self-certify it and give you a certificate.
Does MaxHeatUFH install electric underfloor heating?
No. MaxHeatUFH supplies the kit and passes installation enquiries to vetted approved installers.
Why is my quote much higher than the per m² price?
Per m² prices usually cover the heating only. Lifting the old floor, levelling, insulation, tiling and electrical work are often extra, so ask for an itemised quote.
