Underfloor Heating Costs in 2025: Real Prices UK Homeowners Can Expect
Thinking about giving your home that lovely warm-floor feeling this year? Underfloor heating isn't just a luxury in 2025. It's often a clever way to make your space more comfortable and potentially reduce long-term energy bills. The real question for most people isn't whether it feels good, but exactly how much it's likely to cost. If you're in London, a Manchester terrace, or a barn conversion in the Dales, you'll find that location, as well as the type of system and installation complexity, all play crucial roles.
Let's look at what you might honestly pay, region by region, and system by system, so you can budget with real confidence.
Electric vs. Wet Underfloor Heating: Average Costs per m² in 2025
When it comes to underfloor heating, the two main choices are electric underfloor heating systems (also called "dry") and water underfloor heating systems ("wet"). Across the UK this year, electric underfloor heating typically sits between £60 and £100 per m² for supply and basic installation. Wet underfloor systems, which circulate warm water through pipes, normally cost from £100 to £120 per m². Sometimes rising to £140 or even £150+ per m² when things get complicated or you're dealing with premium finishes, high-end controls, or rush jobs. Understanding wet vs electric underfloor heating systems is crucial for making the right choice for your property and budget.
Why Does Your Postcode Matter? Regional Pricing Insights
If you've ever compared the price of almost anything in London versus, say, Newcastle or rural Yorkshire, you'll know the impact of postcode. The same holds true for underfloor heating. Labour rates in the capital, Surrey, and much of the South East are regularly higher, not just for installation but for any prep work required. In central London, you might see electric installations nudging £110 per m², while a similar job in Glasgow could still be as little as £65-£85 per m². Wet systems in urban hubs like Birmingham or Bristol often hover near the £125 mark, while in smaller northern towns, it's not unheard of to see quotes closer to £95 per m². Especially where competition is fierce.
The price gap reflects not just labour but local material costs, transport factors, and the busy pace of local tradespeople. Remember, if your home is isolated or access requires special equipment, extra charges can apply just to get materials and installers on site.
Installation Considerations: New Build vs. Retrofit and Cost-Saving Tips
Underfloor heating is almost always simpler, neater, and less expensive to put into new builds than into older homes you're retrofitting. Why? In a new home, everything is accessible. The floor's already exposed, and installers can lay pipes or cables before the final floor finishes go down. For these projects, electric systems sometimes come in at £50-£75 per m², and wet systems at £100-£110 per m².
Retrofitting, especially in homes with stone floors, tricky layouts, or a need to upgrade subfloors or insulation, often drives up costs fast. That's when you may see prices at the upper end of the ranges. Removing existing floor coverings, transporting waste, and instating new screeds or insulation all push costs northward. Where possible, combining underfloor heating installation with other renovation work (like fitting a new kitchen or bathroom) can spread some of these extra costs over the whole project. Possibly reducing your quoted rate for heating alone.
It's tempting to cut corners to save money, but reliable installation is essential. Even the best system, if badly fitted, won't deliver even heat or the efficiency you expect. Avoiding common underfloor heating installation mistakes can save you significant headaches and additional costs down the line.
Understanding Energy Usage: What 26p/kWh Means for Your Bills
No matter where you live, running costs depend on your home's insulation, your habits, and. Of course. Energy prices. In 2025, the UK's average electricity price for homeowners is hovering around 26p per kWh. Electric underfloor heating typically uses between 100-200 watts per m² (0.1-0.2 kWh each hour for every square metre actively heated).
So, for a medium-sized bathroom (4 m²), running the system for four hours a day would land you somewhere around £1 in daily electricity use. Wet systems, usually connected to a gas boiler or heat pump, are much more economical for larger areas. At just 6-7p per kWh for natural gas. The savings can add up quickly in open-plan kitchens, living spaces, or full ground-floor retrofits.
Don't overlook how local climate, how well-insulated your floor is, and your chosen thermostat settings can swing these numbers. Investing in smart controls and zoning (heating rooms only when you actually use them) remains one of the simplest ways to keep your bills in check.
Choosing a Reliable Supplier: Why It Really Matters
The supplier you choose for your underfloor heating system impacts not just your upfront price, but also long-term value and peace of mind. In a growing and competitive market, reliable providers such as ThermRite have developed reputations for delivering quality components, helpful after-sales support, and transparent advice. These qualities matter as much as price, especially when you need honest recommendations about the right system for your property type, whether it's a city flat or a rural stone cottage.
A trustworthy supplier stands by their products, helps troubleshoot any teething issues post-installation, and ensures parts are certified to UK standards. If you're buying as a homeowner, look for clear warranties on mats, cables, and piping. Trade buyers value suppliers who offer detailed technical data sheets, prompt delivery, and knowledgeable support staff who can advise on both products and project planning. Saving a few pounds with off-brand kits can risk both comfort and warranty protection. Sometimes costing more in the long run.
What Does the Future Hold? Long-Term Savings and Final Thoughts
Nothing beats the first steps on a warm floor on a winter morning, but in 2025, it's the bottom line that often dictates whether homeowners take the plunge. While installation costs may seem high at first glance, the potential for reduced running costs. Thanks to modern thermostats and ever-improving insulation. Means your investment could start to pay back within a few years, especially if you're upgrading from inefficient radiators or older electric heating.
Experience shows that adding underfloor heating during a larger renovation, or planning ahead with a new build, consistently yields the best value for money. For those living in pricier areas, shopping around and speaking directly to reputable underfloor heating suppliers can unearth deals and flexible options. It's the little details, from online technical support to solid product guarantees, that build real trust.

Frequently Asked Questions
How does the cost of underfloor heating compare to radiators in 2025?
In general, underfloor heating offers more even warmth and a modern feel, but the initial outlay is often higher than for standard radiators, especially for wet systems. Over time, underfloor heating can reduce energy use, particularly in well-insulated homes and large open areas. Many homeowners find the comfort and potential efficiency worth the investment.
Can I retrofit underfloor heating in an older home, and is it worth it?
Absolutely. There are now more options than ever for fitting underfloor heating in older properties, though costs may rise due to the need for subfloor preparation or added insulation. Retrofitting can be very worthwhile, but it's wise to consult with your supplier about specific challenges in your property before starting any work.
Are running costs predictable, or do they change year on year?
Running costs do fluctuate as energy prices shift, but the biggest influences remain how efficiently you use your system and the insulation level in your home. Smart thermostats, zoning, and good design choices can all help keep your bills manageable, whatever happens with energy rates.
Which is easier to install: electric or wet underfloor heating?
For most single rooms or small retrofits, electric systems are generally much quicker and cheaper to lay, with minimal disruption. Wet systems become more cost effective and practical for new builds or large open-plan spaces, though their installation takes more time and expertise.
How do I know if a supplier is reputable?
Look for clear guarantees, a commitment to technical support, and transparent breakdowns of what is (and isn't) included in your quote. Suppliers with long histories and specialist knowledge, like ThermRite, tend to offer more consistent value and peace of mind.
