How Much Does Underfloor Heating Cost?

UFH is gaining popularity thanks to its comfort and energy-saving benefits, however, how much does underfloor heating cost? If you’re considering this method, understanding all costs involved is crucial. In this blog, we’ll discuss the factors influencing the cost while also giving a ballpark figure for materials, installation and running cost

Factors affecting underfloor heating costs

Underfloor heating cost can vary greatly depending on system type, size of project, and preparation required. Every home/project is slightly different, meaning each home needs to be evaluated differently.

UFH System type

Cost of underfloor heating will first depend on the type being installed. Electric underfloor heating uses a heated cable which come in a loose cable or mat. This option is simpler to install, making it a popular choice for renovations & bathrooms. This is a cheaper option to install but is also slightly more expensive to run.

A Wet UFH systems works by circulating heated water through a network of pipes installed under the floor. This method requires a more intricate setup, using more materials. Preparation and installation is also more substantial increasing the overall cost. The main benefit to installing wet UFH is a reduction in energy costs.

Deciding between an electric or wet system is the first process of calculating cost. Not sure which one is right for you? Check out our electric vs water underfloor heating comparison to explore the pros, cons, and key differences in more detail.

Size of Area (Cost per m2)

If the system is a single zone, the room size will be the key component. This impacts the amount of material required for installation. Larger spaces demand more materials and labour for effective coverage. Our single zone wet kits and electric kits are a perfect place to start. Check these out for an accurate cost for materials based on your room size.

Expanding beyond a single room involves additional material costs. For electric systems, factor in additional costs for electric mats and controls needed per room. Calculating underfloor heating cost for a wet systems is more complex. The number of zones will affect manifold size, pipe quantities, and system controls.

System Control

The cost of controls varies depending on type, brand, and features. For wet UFH you’ll need a thermostat for each zone in the system, an actuator for each manifold port, and a wiring centre for overall system control. It’s important to consider your specific heating needs and preferences when choosing controls. Smart thermostats, while having a higher initial cost, provide more features that contribute to energy efficiency and long-term savings. A sought-after feature is mobile control, achieved through a smart hub.

Preparation Work Needed

Subfloor preparation depends on the type of system being installed. For example, overlay systems require a clean, solid surface. This might involve applying levelling compounds or performing additional work to create a smooth, flat foundation. To start, assess your existing subfloor to understand its condition and suitability for the chosen UFH system. Some task include;

• removing floor covering/floorboards
• Removing skirting
• levelling/cleaning subfloor
• Installing insulation

Evaluate current insulation levels to ensure they meet current standards. Adding insulation throughout your home will help prevent heat loss, improves energy efficiency, reducing heating costs. Floor preparation is a key step and may add some UFH costs to the overall project. Addressing any issues at this stage will ensure a smooth installation and ensure long-term performance.

Wet Underfloor Heating Costs

Wet underfloor heating costs can vary depending on the system type, number of zones, and level of control required. Our quotation service provides a free material estimate, giving you a tailored breakdown of all the materials you’ll need for your project.

Average Material Costs per m²

The table below displays a rough cost for various wet underfloor heating system. Prices are based on a single zone system and may increase for multizone setups.

Wet UFH System Installation and Labour Costs

We’ve included a rough installation cost based on feedback from our trade customers. This should serve as a general guide, but please note that prices will vary depending on your location and project complexity.

• Average  Screed Installation –  £1000 – £3000
• Average Overlay/Between Joist system – £2000 – 4000

Other material and preparation costs for screed, insulation and preparation may be charged by the installer. The best way to get an accurate estimate is to obtain a quotation from an installer. Contractors can provide costs specific to the requirements of your project.

Average wet underfloor heating running costs

Wet underfloor heating systems can be up to 25% more efficient than traditional radiators, and up to 40% when paired with a heat pump. In 2025, with average gas prices at approximately £0.07 per kWh, this form of heating remains highly energy-efficient, helping to keep running costs low.

Typical running costs:

• £5–£10 per m² per year
• £600–£800 per year for an average 100 m² home

A wet underfloor heating system connects to your existing hot water heat source and operates efficiently at lower flow temperatures. This allows you to reduce your boiler’s temperature setting, with potential savings of around £10 annually for every degree lowered. Because of its low-temperature operation, wet underfloor heating is also well-suited to renewable heating systems, such as air source and ground source heat pumps.

Electric underfloor heating costs

Electric underfloor heating systems are generally easier and cheaper to install than wet systems, particularly in smaller spaces. Fewer components also reduces material cost in comparison to a wet system. The main drawback is the increased running cost. Electricity prices are around 3x greater than gas which can add to rising costs when heating a whole home.

Average materials costs per m2

The cost of electric underfloor heating materials depends on:

• Type of mat or cable used
• Brand
• Power output (wattage)
• Size of the area being covered

Generally, the price per m² decreases as the installation area increases. Higher power output systems may cost more due to the need for longer cable.

• Electric mat kits under 5m²: £40–£60 per m²
• Electric mats over 5m²: £20–£40 per m²
• Clearance options: As low as £10 per m²

Other materials may include insulation, a thermostat & self levelling screed depending on system type.

Electric UFH installation and labour costs

Electric underfloor heating is generally easier to install  in comparison to a wet system.  Installation can take between a few hours to 1-2 days depending on the size of the heated area.  We’ve included a rough installation cost based on feedback from our trade customers. This should serve as a general guide, but please note that prices will vary depending on your location and project complexity.

• Electric Underfloor Heating Installation –  £500 – £2000

Labour costs can be reduced further but it depends on how comfortable you are with DIY projects. It is important to use a qualified electrician to connect to mains power. Make sure you understand the installation instructions well and create a plan. By doing this, you can figure out which parts you can handle based on your experience.

Is electric underfloor heating expensive to run?

The cost of running an electric underfloor heating system tends to be slightly more expensive than a wet system. This is because electricity rates in 2025 are around 25.73p per kWh, 3 times the price of gas per kWh.

• £15-20 per m² per year
• £150–£200 per year for 10 m²

When the area reaches the desired temperature, the heating mat will switch off and cycle on and off to maintain that temperature. Ensuring your space is well insulated will help reduce running costs, as less energy is needed to maintain warmth. Choosing a higher power mat can also improve efficiency by reducing heat-up time. While it uses slightly more power during operation, the mat will be on for a shorter duration, which can lower overall energy use.

Water vs electric underfloor heating costs

Electric systems are generally less expensive to install, especially in smaller areas. Material costs are lower, and there’s less preparation work involved making them ideal for single room upgrades. The main drawback is the running cost when heating a large area. This is why electric underfloor heating is recommended for smaller projects.

Wet systems, require more preparation and are often part of a larger renovation or new build. Installation is more complex and labour-intensive, but they offer significant long-term energy savings — particularly when used in larger areas or whole-home heating setups. If you’re planning for the future and want energy efficiency across a full property, wet UFH is the more sustainable choice.

While comparing costs side by side is helpful, choosing the right system really depends on your project size, heating goals, and budget. Find out more about Wet vs Electric UFH to choose the right system for your project.
