Professional underfloor heating installation costs
Once you know you want underfloor heating, the next step is to hire the right professional.
Professional underfloor heating installation costs typically include:
- Materials: heating mats or pipes, insulation boards, and controls such as thermostats
- Labour: skilled installation, system testing, and commissioning to ensure safety and efficiency
- Additional work: floor preparation, possible removal of existing flooring, and making adjustments to accommodate the system
These elements combined determine the total cost per square metre, which usually ranges from £40 to £140 depending on the system type and project complexity.
To get the best price for your underfloor heating project, you can talk to multiple professionals near you and compare their services. Just post your job on MyBuilder today and connect with heating engineers near you. It’s the easy and quick way to get in touch with them.

Electric vs. hydronic underfloor heating costs
When you are considering underfloor heating for the first time, it's key to understand the differences between electric and hydronic systems:
Electric underfloor heating uses electric mats or wires to generate heat. It’s typically cheaper and faster to install, ideal for smaller rooms or renovations, but can have higher running costs due to electricity prices.
Hydronic systems circulate warm water through pipes beneath the floor, often powered by gas boilers. While installation costs are higher, they offer lower long-term energy bills and are more cost-effective for larger spaces.
For example, installing a hydronic system for a 100m² area might cost around £5,000 plus VAT. Electric systems suit smaller areas better, whereas hydronic systems deliver savings in larger installations.
How to retrofit underfloor heating
Retrofitting underfloor heating is possible but more complex and costly than new builds, as it requires removing existing flooring and adjusting floor levels.
The cost of retrofitting underfloor heating can vary greatly depending on factors such as the system type, the condition of the existing floor and the extent of preparatory work required. Removing existing flooring can vary in cost depending on the material.
Here are some average costs:
| Flooring Type | Average Removal Cost |
|---|---|
| Carpet | £1 – £4 per m² |
| Laminate | £5 – £10 per m² |
| Vinyl | £5 – £12 per m² |
| Ceramic Tiles | £13 per m² |
| Wood Flooring | £2 per m² |
Note: Costs vary based on room size, labour rates, and regional differences. Consult a local professional.

Beware of these hidden underfloor heating costs
When you are planning underfloor heating, there are some additional costs that could come up during the process.
Here’s some hidden costs you should be aware of:
Insulation: Essential for efficiency, costs range from £60 to £115 per m² depending on floor type.
Flooring: Materials like tile or stone conduct heat well, with installation costs between £35 and £100 per m².
Thermostat installation: Costs typically fall between £100 and £200 for quality controls.
Maintenance: Annual servicing costs range from £100 to £200 to keep the system efficient.
Running costs: Electric systems can cost around £5.42 per month per m², higher than water-based systems.
Considering the complexity and precision required for underfloor heating installation, it's important that you hire a recommended professional to make sure the job is done right.

Long-term underfloor heating cost benefits
Underfloor heating is an increasingly popular modern heating solution that offers numerous benefits beyond warmth and comfort. Take a look at the long term benefits:
- Provides efficient, even heat distribution at lower temperatures, reducing energy consumption.
- Frees up wall space by eliminating bulky radiators, enhancing room aesthetics and layout options.
- Increases property resale value with its appeal as a modern, energy-efficient upgrade.
- Safer for homes with children and pets due to lower surface temperatures and no exposed hot elements.
These advantages make underfloor heating a smart investment for both comfort and long-term cost savings.

FAQ: Common questions about underfloor heating costs
How does energy consumption impact the running costs of underfloor heating?
Underfloor heating is designed to be more energy-efficient than traditional radiators as it operates at lower temperatures- usually between 27 to 32°C for floors- - and provides consistent and uniform heating. This efficiency can lead to reduced energy consumption, potentially lowering the running costs.
What are the potential challenges of installing underfloor heating?
Underfloor heating systems come with several challenges. The initial installation cost can be high, especially for retrofits requiring floor adjustments. Installation time is longer than traditional systems, potentially delaying projects.
Does underfloor heating work with heat pumps?
Yes! Water-based systems pair well with air source or ground source heat pumps, improving efficiency and reducing energy costs. For all air source heat pump installation costs, visit our informative price guide.
Can I leave my underfloor heating on all the time?
For best efficiency, it’s recommended to set a consistent low temperature rather than turning it on and off frequently. Water-based systems work best when kept at a steady heat.
Does underfloor heating reduce humidity?
Yes, underfloor heating helps to prevent dampness and condensation, making it a great choice for bathrooms and kitchens. If you’re considering renovating your bathroom, visit our price guide for all new bathroom costs.

plumber made my boiler issues worse :(
Anonymous user 26/06/2026 - 7.32 AM
i had a plumber come round to try and fix our hot water that was running hot cold. its a 10 year old combi boiler that has been serviced every year and only just started having this problem. since he's visited the hot water now runs very hot and rumbles/rattles for a few seconds after it gets going. it has also a few weeks after he supposedoly fixed it has now started to cycle between slightly cooler and hot again. I think there is air in the central heating system as sounds like water running when it's switched on which never used to happen before. there is a water hammer (that the right term?) when toilet flushed and hot water opened too quickly- as in pipes rattle im worried that maybe he's played with the water pressure or something as i've noticed that water also comes out of the bathroom tap when the hot water is on full. just weird. any advice on what the problem could be or what he might have done wrong? i'll be getting a plumber in to take a look, but would appreciate some feedback on what people might think is going on

Honeywell programmer st9400c hot to touch
Anonymous user 21/06/2026 - 3.15 PM
Hi, I just wondered if it's standard for this unit to feel hot to the touch in the top left corner all the time? Even when the screen and the heating are off? I find it strange to design an electrical unit that way, as if there isn't adequate cooling, heatsink etc. but what can you do? It was installed by a professional gas safe engineer who also fitted a new boiler. He tested it all as working ok. Just so long as it won't overheat and catch fire. I wonder if newer models run cooler? Thanks.
