How much does underfloor heating cost?

From cutting your energy bills to helping your home become more eco-friendly, underfloor heating offers ample benefits to homeowners. But before looking at getting underfloor heating installed, it’s important to know how much it could cost you. To help you plan ahead, this price guide will take you through the costs of underfloor heating, what you can do to keep the largest costs down and other important information you need to know. All prices quoted are estimates that are accurate as of January 2024.

When the temperatures drop, there’s nothing more comforting than knowing your property comes with a heating system that can take the edge off. Underfloor heating is one of the most effective ways to heat your home, making it warm and cosy as well as cost efficient. But from understanding underfloor heating costs to the price of hiring a professional heating engineer who can help install your new heating system, it’s important to have a good grasp of the costs before getting stuck into the project.


Average underfloor heating costs

Sitting underneath your floorboards, underfloor heating means you can walk around your home in bare feet without the feeling of a cold floor bothering you. But there are many more advantages too. Underfloor heating systems heat your home more effectively than radiators, meaning that not only can you save money on your heating bill, but you’ll also be heating your home in a more eco-friendly way. 

There are two main types of underfloor heating systems: electric and wet. Depending on which system you would rather go for, you can expect these systems to be priced differently. You can see the average prices of each system in the table below. 

Underfloor heating systemAverage price per m2
Electric in renovation£60 to £85
Electric in new build£50 to £75
Wet in renovation£120 to £135
Wet in new build£135 to £185

But these costs aren’t the only ones to be aware of. Installing underfloor heating systems might require making changes to your floors to make them suitable for the new system. This could involve specialist equipment, materials and even a skip to dispose of any refuse items. 

Then there are also the costs of hiring skilled and experienced heating engineers you can rely on to get the job done. Remember that if you’re connecting your underfloor heating system to a boiler, it will need to be carried out or certified by a registered Gas Safe engineer, so it’s always a good idea to  hire a professional heating engineer with the correct credentials.

How much does underfloor heating cost?

The costs of installing underfloor heating vary for two main reasons. The first is the type of property and its overall condition. For example, if you’re in a new-build property it can be easier to install underfloor heating as the floors are generally in a good condition and will adhere to modern building standards that make it easier to remove and re-install these floors. In a renovation where your property may be larger, this can be a longer and more labour-intensive process, which can add to the costs. 

The second consideration is the type of underfloor heating. A wet, or water, system operates by heating your floors via a series of underfloor pipes that are connected to your central heating system. These systems are often more complex to install, making them better suited to new-build homes. However, they are the more energy-efficient option. 

A dry, or electric, system works by fitting heating wires under your floor that use mains electricity to heat the floor. This type of system is easier to install but more expensive to run as it uses electricity rather than central heating. 

On top of these main two factors, you’ll also need to bear in mind materials, size of your property, equipment and labour costs. All of which mean that the average cost of installing an underfloor heating system is usually between £500 for a smaller installation and £8,000 for a larger project. 

Cost of running underfloor heating

In many ways, underfloor heating is a more efficient and cost-saving method of heating your home. With pipes or microwires under the floors, you can walk around in more comfort without having to wait for radiators or other heating methods to warm these surfaces. 

At the same time though, as this heating will be radiating through the floor, it could take longer to heat a large room. So, the question is whether its more efficient to run underfloor heating or other forms of heating.

There’s no set answer as running costs vary depending on the size of the property and rooms. But as an average, a wet underfloor heating system typically costs between £184 and £552 annually for a room sized between 10m2 and 30m2. Electrical systems will cost more, but these prices vary based on your provider’s electricity costs. 

Cost of installing underfloor heating in a renovated property

Installing underfloor heating in a renovated property can cost more than carrying out the same installation in a new build. Older properties have been built following different building regulations and rules. And while the floors in any property need to be temporarily removed to install underfloor heating, doing so in a renovated property can be more challenging due to the condition and age of the floors. 

Moreover, renovated properties tend to have more complex heating systems, meaning more materials, equipment and labour costs may also need to be factored into your budget. As an average, however, you can expect the average cost of installing underfloor heating in a renovated property to be between £4,000 and £11,000

Cost of installing underfloor heating in a new build

Installing underfloor heating in new-build properties is usually easier for two reasons. The first is that as the properties are newer, the floors are generally in better condition, making a quick and smooth installation easier. The second is that newer properties conform to modern building standards so there’s less risk of damage and floors can be removed more easily. 

For this reason, installing underfloor systems can be done more quickly and cost effectively than in renovated properties. As an average, you can expect to pay between £2,300 and £6,500 for these projects. 

Cost of removing floors

Removing the floors of your property makes installing an underfloor heating system possible. But the type of floor you have will determine the cost and the amount of time this will take. 

A professional floor fitter will need to inspect the floor to prepare it and ensure it can be done without damaging the material. This will typically cost £6 and should only take a few moments. The cost of removing the floor itself can vary. While most floor tiles will typically cost around £13 per m2, some vinyl floors can take longer and cost more to remove and can cost between £14 and £20 per m2. The cost of removing floors will be including in your quote but it’s always a good idea to speak to a professional to find out how much removal will cost. 

Cost of equipment hire

Installing underfloor heating requires a skilled hand and can require specialist equipment, especially if the installation is taking place in an older property. While these costs will also be included as part of your project quote, it’s worth noting some of the key items that might be used to carry out the job and how much they typically cost. A floor and tile lifter, for example, is a key component of lifting your floor and often costs around £52 per day to hire. 

Cost of hiring a heating engineer

When it comes to dealing with heating and technical home improvement works, it pays to find a professional and experienced heating engineer near you. Removing and protecting delicate flooring and dealing with complex pipework involves skills, experience and qualifications that make these projects well suited to skilled heating engineers

Labour costs make up a large part of any quote as installing underfloor heating can be tricky. Often though, you should expect to pay between £200 and £300 a day in labour costs. Depending on your location, the size of your property and how much needs to be installed, these costs can be higher or lower. 

Thankfully, with MyBuilder, there’s an easy way to find a heating engineer in your area.

Cost of underfloor heating pipework

If you’re getting a wet underfloor heating system, and especially if you’re living in a renovated property, you will need additional pipework to connect your installation to your boiler. 

Remember that incorrectly fitted pipes could leak or get damaged, so make sure to speak to a specialist heating engineer to help with this installation.  

Two of the most commonly used pipes for this pipework are PEX and PERT pipes. The main difference between the two is that PEX pipes can withstand greater pressure and temperatures up to 95 degrees centigrade, while PERT pipes can withstand up to 60 degrees centigrade. Depending on which pipes you are having fitted, the average cost of this pipework often costs between £10 and £15 per m2.

A heating engineer may carry out this pipework themselves, but make sure you check whether you need to hire a plumber to make sure that all the pipes have been connected correctly. 

Cost of installing microwire heating

If you’re installing a dry, or electric, underfloor heating system, your heating engineer will include the cost of sourcing and installing microwire heating. In dry systems, microwires under your flooring will heat up and radiate warmth through the floorboards, so these are an important part of your installation. 

There are various materials and types of cable that can be used for this job, such as mesh electric systems, matt electric systems and foil systems. Depending on which you go for, installation prices vary, but the average cost of installation for electric underfloor heating is around £25 per m2.

Remember though that you’ll also need to hire an electrician to inspect your new system, ensure it is safe and connected properly. Moreover, you may need to buy a new thermostat to monitor your new heating system, so remember to factor in this price too. 


How long does installing underfloor heating take?

Underfloor heating installation doesn’t usually take very long, but there are a couple of factors that mean your installation could take longer than anticipated. Firstly, certain types of flooring can take longer to safely remove and refit. Secondly, a wet heating system can take longer to install, as it may involve more substantive pipework. Finally, the number of rooms that need to be looped into the system can also impact timescales. 

With all this being said though, you should typically expect your installation to take between two and three days, with larger projects sometimes taking up to four. 

How to reduce underfloor heating costs

When it comes to home improvement projects, there are usually some easy and straightforward ways of reducing the costs. Here are three tips on how you can lower the cost of your underfloor heating installation:

  • Get like-for-like quotes from heating engineers: It’s always a good idea to get quotes from at least three different heating engineers. Different tradespeople could source different materials, have different qualifications and experience and have different distances to travel to you. All of which can lead to your quote being potentially higher than you expected. Shop around for different quotes and there’s every chance you can find a better quote. 
  • Install the right system: Not all properties are well suited to a wet or dry underfloor system, so do your research to find out how much additional pipe or cable work will be needed to properly install your new system. If the work could be extensive, maybe your property would be better off with an alternative. 
  • Trust a specialist: If underfloor heating systems aren’t installed properly, they can lead to costly repairs in the future and can be a potential health hazard. If you’ll be doing some of the installation yourself, make sure to hire an electrician or plumber to sign off on your work and make sure it’s safe. 



Can I install my own underfloor heating?

When not fitted correctly, underfloor heating can lead to costly repairs further down the line. While parts of your installation, such as removing and refitting your flooring, may be done easily by yourself, it’s highly recommended to work with a professional tradesperson when it comes to the fitting and connection itself. Remember that when connecting your heating system to your boiler, a Gas Safe-certified engineer will need to inspect the work and ensure it is safe. 

Can I install underfloor heating without raising the floor?

Underfloor heating doesn’t always require your floors to be raised. Many electrical systems are designed to work with your floors at their current level and it’s not always necessary to raise your floor for water-based heating systems either. However, it’s best to speak to a professional, because depending on the age and structure of your property, this might not be the case. 

Which underfloor heating system is more efficient?

Your underfloor heating system’s efficiency can vary depending on factors like the strength of your boiler, which type of system you have and the age and condition of your property. On the one hand, water-based systems use between 15 and 40% less energy than radiators. And while electric systems may use slightly more energy than this, they’re cheaper systems to install than water systems, so you could find better savings by opting for this type of system. 

Your underfloor heating checklist

So, are you ready to explore underfloor heating systems for your home? If you are, it’s time to get the ball rolling. We’ve put together an easy-to-follow checklist to walk you through the process of getting your system installed.

  • Use MyBuilder to get a range of quotes: MyBuilder is the easiest way to find a reliable and experienced heating engineer near you. All you need to do is post your job to our smart matchmaking tool and you’ll quickly be connected to professionals in your area. It’s then up to you to compare the different options, quotes and expertise and make the final decision. 
  • Decide which system is best for your property: As explained above, not all underfloor heating systems are a good match for your property. You will need to work out the costs and drawbacks associated with both types of system, but often the best way to do this is to speak to professionals who can advise you on the best system for your home and the amount of work needed to install both. 
  • Get the timing right: If you’re making underfloor heating your main source of heating, it goes without saying that getting these systems installed during the winter means you could be without heating for a couple of days. It’s always a good idea to plan ahead and consider getting your installation done during the warmer months so your new heating source is ready to go when needed.
