Underfloor heating has become a popular option for homeowners who want a more efficient and comfortable way to heat their homes. However, one of the first questions that comes to mind is: how much will it cost to install? Whether you're considering electric or water-based underfloor heating, installation costs can vary based on several factors. As an experienced electrician in London, we'll break down the costs to help you decide if it’s worth the investment.
Types of Underfloor Heating Systems
There are two main types of underfloor heating systems: electric and water-based. Understanding the difference between these two systems can help you figure out which option suits your home and budget.
Electric Underfloor Heating: This type of heating system uses electric cables or mats installed directly under your flooring. It’s generally easier and quicker to install than water-based systems, especially in existing homes or renovation projects.
Water-based Underfloor Heating: Also known as a wet system, this setup uses pipes connected to your boiler. Warm water is circulated through the pipes to heat the floors. It’s more complex to install and is typically more suited to new builds, though it can be installed in existing homes too.
Average Installation Costs of Underfloor Heating
The cost of installing underfloor heating varies depending on the type of system you choose and whether it’s for a new build or a renovation. Here’s a rough estimate of what you can expect to pay:
Electric Underfloor Heating:
New build: £50 - £75 per square metre
Renovation: £60 - £85 per square metre
Water-based Underfloor Heating:
New build: £120 - £135 per square metre
Renovation: £135 - £185 per square metre
For a typical room, the total installation cost can range from around £500 to £8,000, depending on the size of the space and the system you choose.
Electric vs. Water-based Underfloor Heating: Which Is Cheaper to Install?
When it comes to upfront costs, electric underfloor heating is generally cheaper to install than water-based systems. Electric heating mats are easier to fit, especially in renovation projects, as they don’t require extensive changes to your home’s structure. The simplicity of installation often reduces both labour time and costs.
On the other hand, water-based underfloor heating systems require a more involved installation process. The pipes need to be fitted under the floor, which can involve raising the floor level or extensive labour, particularly in existing properties. This makes water-based systems more expensive upfront, but they may offer long-term savings in running costs, especially in larger homes.
Factors Affecting Underfloor Heating Installation Costs
The cost of installing underfloor heating can fluctuate based on a number of factors. It’s not just about the size of your home but also the complexity of the job. Here are some key factors that could impact your final bill:
Size of Your Home: The larger the area you want to heat, the higher the installation cost. A bigger space requires more materials and time, especially with water-based systems, which are more labour-intensive.
Age of the Property: Older homes might require more preparation before installing underfloor heating. For example, floors may need extra insulation, or the layout could demand more labour. This can push the cost up, especially if structural changes are needed.
Number of Rooms: Installing underfloor heating across multiple rooms means more wiring or piping, which will increase both material and labour costs.
Existing Flooring: If your floors need to be removed and replaced, this will add to the overall cost. Installing heating in areas with existing tiles, for instance, could involve higher labour costs than installing in a new build or during a full renovation.
Is Underfloor Heating Expensive to Run?
Once installed, underfloor heating can be more economical to run than traditional radiators, but the exact running cost depends on the type of system and how often you use it.
Electric Underfloor Heating: This system tends to be more expensive to run compared to water-based systems because electricity costs more than gas. For a 10m² room running for four hours a day, you could expect to pay around £35 per month. However, it's often cheaper to install, which might make it a good option for smaller areas like bathrooms or kitchens.
Water-based Underfloor Heating: While installation costs are higher, this system is more energy-efficient in the long run. It works at lower temperatures than radiators, making it more cost-effective for heating large spaces. If your system is connected to a gas boiler, running costs could be as low as £2.10 per hour, compared to £2.90 per hour for an electric system of the same size.
Underfloor Heating vs. Radiators: Installation Costs
When comparing the installation costs of underfloor heating and radiators, underfloor heating tends to be more expensive upfront. Here’s why:
Underfloor Heating: Installing underfloor heating requires more labour, as the floor must be prepared, pipes or mats laid down, and the entire system connected to either the electrical system or boiler. On average, installation costs range from £60 - £185 per square metre, depending on whether you choose electric or water-based heating.
Radiators: Radiators are simpler and quicker to install. A typical gas central heating system with radiators might cost around £3,000 to install, which is generally less than underfloor heating. However, the energy efficiency of underfloor heating may lead to savings over time, balancing out the initial cost difference.
Long-term Savings and Benefits of Underfloor Heating
While underfloor heating may be more expensive to install than traditional radiators, it can offer long-term savings and additional benefits that radiators simply can’t match.
Energy Efficiency: Underfloor heating distributes heat evenly throughout the room, meaning it can run at lower temperatures than radiators while still keeping your home warm. This can result in lower energy bills, especially with a water-based system.
Comfort and Aesthetics: By eliminating the need for bulky radiators, underfloor heating frees up wall space and provides a cleaner look to your rooms. Plus, the luxury of walking on warm floors adds a comfort factor that radiators can't provide.
Increased Property Value: Adding underfloor heating is seen as a premium upgrade to a home. It can increase the overall value of your property, making it a smart investment if you plan to sell in the future.
How to Choose the Right Underfloor Heating Installer
Choosing the right installer is essential for a successful underfloor heating project. Whether you opt for an electric or water-based system, a skilled tradesperson ensures that everything is installed correctly, preventing costly repairs or inefficiencies later on.
When searching for a qualified installer, consider these tips:
Experience and Credentials: Look for installers with specific experience in underfloor heating, particularly for the type of system you’re planning to use. It's a good idea to check their qualifications and whether they are accredited by relevant bodies.
Customer Reviews and Recommendations: Always check reviews from previous customers. Word of mouth or online testimonials can give you a good idea of the quality of the installer’s work and their reliability.
Local Knowledge: Hiring a local tradesperson can be beneficial as they understand local building regulations and might offer more competitive rates. Using directories like Checkatrade can help you find reputable professionals in your area.
Detailed Quotes: Obtain quotes from at least three installers. This will give you a clearer idea of the cost and help you choose the best person for the job. Make sure the quotes include everything from materials to labour costs so that there are no surprises later.
