Can You Add Underfloor Heating to an Existing Home?
Retrofitting underfloor heating into an existing property is possible and can bring energy-efficient warmth to your home. Unlike new builds, where the system is installed during construction, retrofitting involves adding underfloor heating to homes that already have finished floors. Many homeowners opt for this upgrade when renovating, as it enhances comfort without taking up wall space.
If you're considering underfloor heating as part of your home renovation, you'll be glad to know that it works well with most existing systems and layouts.

Retrofitting vs. Refitting: What’s the Difference?
When it comes to adding underfloor heating, it's important to distinguish between retrofitting and refitting.
What is Retrofitting?
Retrofitting refers to installing a new underfloor heating system in an existing home, without major changes to your subfloor or room layout. This is the most common option for homeowners renovating their spaces.
What is Refitting?
Refitting, on the other hand, involves removing an old heating system and reinstalling it elsewhere. This method isn't recommended for underfloor heating, as the wires or pipes can be damaged when trying to remove them. Refitting also voids any warranties or guarantees on the system, which makes it a risky and costly decision.
Choosing the Right Underfloor Heating System for Your Existing Home
When retrofitting underfloor heating, there are a few key factors to consider. Your choice will depend on the type of flooring in your home, as well as how much floor height you're willing to sacrifice.
Impact on Floor Height
A major concern when retrofitting is how much the system will raise your floors. In existing homes, where door heights and skirting boards are already in place, it's important to select a system with a low profile to avoid needing major adjustments. Systems with ultra-thin wires or low-profile hydronic systems work best in these scenarios.
Types of Systems: Electric vs. Water-Based
Electric underfloor heating systems are often the most popular choice for retrofits, as they add very little height and are relatively easy to install. Water-based (hydronic) systems, like the VLo line, are also suitable for retrofits, offering low build-up and energy savings, especially if you’re using modern heat pumps.
Installing Underfloor Heating: Step-by-Step Guide
Retrofitting underfloor heating might seem complex, but the process can be straightforward when done correctly.
Preparing the Floor
To start, the existing floor covering will need to be removed. This includes tiles, carpet, or wood flooring, depending on your home's setup. Once the floor is exposed, the subfloor must be cleaned and prepared to ensure that the new system can be laid smoothly.
Installing the Heating System
Next, the chosen heating system is installed directly onto the subfloor, and if you're using electric heating, the wires will be placed within adhesive layers or under a thin screed for water systems. It’s important to consider adding insulation below the system to help improve energy efficiency.
Laying the New Floor Covering
After the heating system is installed, you can then lay your new floor covering. Whether you opt for tiles, laminate, or wood, it’s important to make sure the floor is solid and properly supported to avoid any future issues.
Which Underfloor Heating Systems Work Best for Retrofitting?
When it comes to retrofitting, not all underfloor heating systems are created equal. Some are better suited for existing homes because of their design and installation process.
Electric Underfloor Heating Systems
Electric underfloor heating is a top choice for retrofitting, particularly because it adds minimal height to your floors. Systems like the StickyMat use ultra-thin wires that can be placed within the adhesive under tiled flooring, which makes them a great option for spaces where you don’t want to raise the floor level significantly. They’re easy to install and compatible with a range of floor types.
Water-Based Underfloor Heating Systems
Water-based systems, like the VLo line, offer low-profile solutions that are ideal for retrofits. These systems work with both traditional boilers and modern heat pumps, making them highly versatile. They are more energy-efficient over time, which can help reduce your heating costs, especially if paired with renewable energy sources like heat pumps.
The type of flooring you choose can impact the effectiveness of your underfloor heating system. Some materials are better conductors of heat, ensuring that your home stays warm and comfortable.
Tile and Stone Floors
Tiles and stone are excellent choices for underfloor heating because they conduct heat well, providing even warmth across the room. These materials are durable and ideal for spaces like kitchens and bathrooms, where both heat and moisture resistance are needed.
Wood and Laminate Floors
Wood and laminate can also be paired with underfloor heating, but it’s important to check the manufacturer’s recommendations to ensure they’re compatible. Engineered wood tends to work better than solid wood due to its ability to expand and contract with changes in temperature. If you choose these types of floors, be sure they’re well-suited for use with underfloor heating.
Carpeted Floors
If you have carpeted floors, underfloor heating can still be an option, but you need to ensure the carpet and underlay aren’t too thick. Thicker materials can act as insulation, reducing the efficiency of the heating system. Low-tog carpets are recommended for the best results.
One of the main reasons homeowners choose underfloor heating is its energy efficiency. In older homes, where traditional heating systems may not be as efficient, underfloor heating offers a more modern and effective way to warm your spaces.
Why Underfloor Heating Saves Energy
Underfloor heating operates at lower temperatures than radiators while still providing comfortable warmth. This makes it a more energy-efficient option, as it requires less energy to maintain a comfortable temperature. Since heat rises evenly from the floor, there are fewer cold spots, and the warmth stays where you need it most.
Comparing Underfloor Heating to Traditional Systems
Traditional heating systems, like radiators, work by heating the air around them, which can lead to uneven heating. Rooms often feel warmer near the radiator but cooler elsewhere. Underfloor heating, on the other hand, provides a consistent, even heat that spreads across the whole room. Over time, this can result in lower energy consumption and reduced heating costs.
Tips for Maximising Underfloor Heating Efficiency in Existing Homes
While underfloor heating is naturally more efficient than other systems, there are ways to further enhance its performance in older homes. By making a few additional adjustments, you can maximise your system’s efficiency and save even more on your energy bills.
Insulate Properly
Good-quality insulation is crucial for getting the most out of your underfloor heating system. Insulation helps to direct the heat upwards, where it’s needed, rather than allowing it to escape through the subfloor. If you’re retrofitting underfloor heating, it’s a good idea to install a layer of insulation underneath the system. This will help the system heat up faster and maintain warmth for longer.
Use Smart Thermostats
Smart thermostats can further improve the efficiency of your underfloor heating by giving you more control over when and how the system operates. Features like SmartGeo technology can learn your schedule and automatically adjust the heating to suit your routine, reducing energy waste. You can also monitor and control your heating remotely via smartphone apps, ensuring your home is always warm when you need it to be.
Do You Need Professional Help for Retrofitting Underfloor Heating?
While retrofitting underfloor heating can be a great addition to your home, it’s important to recognise when professional help is needed. Certain aspects of the installation process, particularly those involving electrical work, should always be handled by qualified experts.
Hiring a Qualified Electrician
For electric underfloor heating systems, a qualified Part P-certified electrician is required to ensure that all electrical work is done safely and in compliance with regulations. This includes connecting the system to your home’s electrical supply and installing thermostats and controls.
Ensuring Proper Installation
Proper installation is key to the performance of your underfloor heating system. An experienced installer will make sure that the subfloor is prepared correctly, insulation is installed where necessary, and the heating system is fitted efficiently. Attempting a DIY installation without the necessary expertise can lead to problems such as uneven heating, system malfunctions, and even safety risks.
Electrical Distribution Considerations
It’s also crucial to design the electrical distribution system carefully to accommodate the power demands of underfloor heating. Professionals can assess whether your current electrical system can handle the new load or if upgrades are needed. This ensures your system runs smoothly and efficiently.
FAQs
Can you add underfloor heating to an existing central heating system?
Yes, you can add underfloor heating to an existing central heating system, especially if you opt for a water-based (hydronic) underfloor heating system. These systems connect directly to your existing boiler or heat pump, allowing them to integrate with your current setup. You may need to install a manifold to control the different heating zones, but this is something a professional can assist with.
How difficult is it to retrofit underfloor heating?
Retrofitting underfloor heating is a manageable process, but it does require removing the existing floor coverings and preparing the subfloor for installation. Electric systems are generally easier to retrofit, as they have thinner profiles and can be installed quickly. Water-based systems may involve more work due to the need for pipework, but both options can be installed efficiently by professionals.
Can underfloor heating be fitted retrospectively?
Yes, underfloor heating can be fitted retrospectively during home renovations. This process is called retrofitting and involves laying the heating system over the existing subfloor and then covering it with new flooring. It works particularly well in spaces where you are already planning to replace the flooring, as the installation can be done without too much disruption.
Can you add in-floor heating to an existing floor?
Yes, in-floor heating can be added to an existing floor, but it requires removing the current floor covering first. Once the old floor is removed, the heating system is laid on the subfloor, followed by new flooring. This is a great option for homeowners looking to upgrade their heating system while renovating a room or replacing flooring.
