How Much Does Underfloor Heating Cost To Run In 2024

So you’re here searching for the grand old question of how much underfloor heating costs to run?

I’ve had electric UFH in my bathroom for the last six months. I’ve been closely monitoring the costs of my smart meter to write this article and relay the information back to you!

I have a small bathroom which is roughly 4m2. My calculations suggest the underfloor heating cost is roughly 40p when using it on full whack for around 6 hours. Not bad, eh?

Some people still expect underfloor heating to be expensive to run. If you can do it yourself, the initial installation cost and ongoing running expenses can represent excellent value for money.

An electric UFH heating solution is definitely the way to go this year! In this article, I will help you understand the various factors contributing to the overall cost.

But what about underfloor heating powered by water?
Electric underfloor heating costs are much higher than wet underfloor heating systems.

The logistics of installing hydronic underfloor heating costs considerably more than electricity. So it is swings and roundabouts!

Let me explain the costs below in a little more detail.

How Much Does Underfloor Heating Cost To Run?

How about installing some underfloor heating? Here’s the breakdown of how much it could cost you in the below situations.

Own A New Build?

Setting up underfloor heating in a new building proves more cost-effective than retrofitting it into an older property.

This is because integrating an underfloor heating system from the outset contrasts with the complexities around altering the heating system of an existing property.

Based on calculations through my research. The installation expenses for underfloor heating in a new build typically range from £2,300 to £6,500, depending on the chosen system.

This calculation was done in 2024.

This makes an electric underfloor heating system cheaper than a hydronic system. This is due to its more straightforward installation process, which any handy DIY Dad can do.

Are You Renovating?

When revamping a property, opting for an electric underfloor heating system proves cheaper than a hydronic system.

Fewer materials and reduced labour costs save you money here. Again, if you can install it yourself, that would be even better.

Underfloor heating costs during a property renovation typically range from £4,000 to £11,000. This is depending on whether the choice is electric or hydronic.

So, choose an electric heating solution if you want cheaper installation costs. If you want to pay less over time but spend more setting it up, a hydronic water heating system is the way to go.

The table below lays it out as an estimate.

Underfloor heating system Average 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

How Much Does Underfloor Heating Cost To Install

Once you’ve grasped the pricing of the system, you now need to factor in the expenses associated with hiring a qualified heating and plumbing engineer to complete the installation.

Unfortunately, estimating the installation cost of underfloor heating can be challenging due to regional differences across the UK and the size and type of UFH systems being installed.

A general rule of thumb could be the installation cost, accounting for approximately 40-50% of the total system cost.

There is also the option of installing the underfloor heating yourself. If you’re not confident, consider hiring a builder for this task before bringing in a plumber to handle the manifold setup, connection to the boiler, and system commissioning.

Can You Install Underfloor Heating Yourself?

Of course, you can! Check out our guide here on installing underfloor heating.

Does Underfloor Heating Cost More Than Radiators

It’s 2024, and if you’re reading this, you’ve lived through the energy crisis of 2023. Electricity is currently more expensive than gas. Your electric UFH will not be cheaper than your well-balanced gas central heating.

Suppose you’re considering a water heating system. In that case, once you get over the initial installation cost, your bills will work out cheaper over time.

Types of Underfloor Heating Systems And Their Costs

There are two main underfloor heating systems as described below.

Electric Underfloor Heating Systems

Electric underfloor heating systems can range from £50 to £200 per square metre. Check out the article I wrote on the best electric underfloor heating kits for some of the best products on the market.

Hydronic (Water) Underfloor Heating Systems

Hydronic underfloor heating systems can range from £70 to £200 per square metre. If you’re a DIY specialist, plan to lay a hydronic heating system with a heat pump.

What Factors Will Contribute To My Underfloor Heating Cost?


This depends on the type of system you choose; remember, installing a water system is more expensive than an electric one. 

Labour costs are the main factor in the installation cost, typically ranging from £50 to £100 per hour. This is where a very handy DIY dad can come into his own and save considerable money. 

Hiring a qualified underfloor heating technician is always a good idea if you need more confidence.

Square Metre Area

The size of your room is also a significant factor in determining your overall cost.

Generally, the larger the area, the higher the cost. The cost per square metre can vary depending on the type of system chosen. Electric systems are more affordable compared to wet systems.

Type of System

As mentioned a few times, electric systems are generally more affordable than wet systems. They require less installation work and materials.

Hydronic systems require additional components such as boilers or heat pumps. These increase the overall cost.

Insulation and Heat Loss

Good insulation will significantly save your wallet. Proper insulation helps to minimise heat loss and ensures that the heat is effectively transferred to the room.

If your home has poor insulation, consider adding additional insulation for your subfloor or walls. This can add to the overall cost of your budget.

Energy Efficiency

Underfloor heating systems are known for their energy efficiency, which can help reduce your energy bills in the long run. Electric underfloor heating systems are typically more energy-efficient compared to traditional radiators.

How To Reduce Underfloor Heating Costs 

It would help if you always sought energy efficiency with underfloor heating. Several effective strategies can be implemented.

Something as simple as adjusting the temperature settings to a slightly lower level can lead to significant energy savings.

This can be more beneficial thanks to the system’s ability to evenly distribute warmth. Integrating a smart thermostat also offers control, ensuring the system operates only when needed.

Another critical factor is ensuring you have proper insulation installed in your home. This obviously helps minimise heat loss and warmth distribution.

Lastly, having regular professional servicing scheduled at least once a year will help maintain your system life and efficiency.

Building Regulations For Underfloor Heating Installation

Compliance with all necessary permissions and building regulations will be needed when installing an underfloor heating system. This step safeguards your investment and preserves your property’s value over time.

Navigating the various standards and regulations associated with different types of underfloor heating can be time-consuming and complex.

It requires thorough understanding and careful consideration to ensure full compliance with legislation. You can check out the building regs here.
