More than just adding a luxury element to our homes, underfloor heating can actually be better for your home than radiators, by making it more energy efficient and even reducing the carbon emissions that your property produces.

In this guide, we’re going to talk you through the benefits of underfloor heating and take a look at the prices you will normally pay to get a system installed in your home.

Underfloor Heating Cost

When it comes to the cost of underfloor heating, you can expect to pay anything from £50 for a smaller job to way over £10,000 for a big installation project.

Here are a few examples of what a company may give you as an underfloor heating price, based on a 60m2 property with a £30 hourly rate for your installer.

You can also break this down into a cost of underfloor heating per square metre, and some installation companies may even give you their costs in that format.

For a wet system, the underfloor heating cost per m2 is typically in the range of £60 to £80 for a bespoke pack that would include all the bits and pieces you would need, from screed to panels and piping.

Like many home improvement projects, the amount you pay can vary depending on a number of different factors. With underfloor heating they include:

  • The floor cover type you choose
  • The current state of your property
  • Which underfloor heating type you want

As well as this, the biggest contributor to price is the materials and the cost of your tradesperson. On average, an underfloor heating installer would charge around £250, although this could alter depending on how long the actual installation will take to complete.

Underfloor Heating Types

Although there are few different underfloor heating options to choose from, really it boils down to the big two of electric systems and wet systems.

Here are a few more details on how they differ:

Electric Systems

If you are looking for a cheaper underfloor heating system or a do-it-yourself project, then an electric system, also known as a dry system, is probably your best option. Not only are they easier to install but they also warm your property up much quicker.

They often work with heated cables being linked into matting which will be rolled out across your flooring surface. You may also find that they come in a few others formats such as cables that are flat, filmed or ribboned.

Once you installer lays out the matting, they will then be built into a thermostat and a supply of electricity, before your usual floor surface is then layed over the top.

If you have stone or tiles on your flooring, then its likely that the wire and cables will be installed, especially if you have an unordinary shaped room. If your room is a standard shape such as a square, then this is where the mesh mats would come in to play. Only if you have laminate for your flooring, would the foil mats be used.

Once they are connected, it is the electricity running through the wires that will create the heat in this system, and you’ll notice that it doesn’t take long for the floor to feel warm. However, because the heat is only running through the wires, a dry system tends not to warm up the actual room as much as a radiator would normally do.

This is why we’d only recommend this system if you are looking for a cheaper option or you only want to install it in a small room, toilet or en-suite area.

Wet Systems

The other popular underfloor heating choice is known as a wet system. There’s a lot more involved in the installation of this product, especially if it’s going into a property which has already been fully built.

For this reason it tends to be more expensive and is only really a worthwhile option (unless you don’t mind the disruption) for a new build home or one that is getting a full revamp or renovation.

Unlike the electric system, the wet version has several different pipes going from the boiler in your home, which then supplies hot water to your underfloor heating, much like they would do to your radiators.

Although a condenser boiler usually works best, there’s no need to have an ultra-modern boiler to make things work, as long as it can handle the extra capacity, then it will more than cope with the new additions. Read more: new boiler cost and boiler service prices.

Your installation professional will lay the pipes underneath your floor, before putting your normal flooring surface back on top. To stop the likelihood of any drips or leaks, the pipes that are used are normally seamless so that there are no connecting pieces that could come loose.

As we mentioned, the installation of a wet system is fairly complex, so we wouldn’t recommend doing this on your own. Despite the extra costs that this may create, the end product will be an excellent system that should last the test of time.

That is all well and good, but we can hear you asking “how much does wet underfloor heating cost to run?”

Well, once it’s installed, you can even expect it to be cheaper to run and definitely more efficient than a radiator system, as it uses a lower water temperature.

Even with a lower water temp, the way in which the wet system heats up a space is identical to that of a normal radiator. With heated water operating through the pipes, the heat transfers through the floor and out into the room itself. Keeping both the floor and your space nice and warm whenever you want it.

Underfloor Heating FAQs

With so much to consider when it comes to whether or not you actually go ahead and get underfloor heating, it’s important not to rush into making any decisions.

Get as much advice as you can and really do your homework as to exactly what is currently available from several manufacturers and installers.

To help you along with that, here are a few common questions that we regularly get asked by people who are looking at getting UFH installed in their home.

Is underfloor heating worth the money?

The only answer is yes, and you’ll soon agree when you step out of the shower on a cold day and suddenly feel the heat under your feet.

Underfloor heating is one of the most luxurious products you can install into your home and as well as making you feel nice and cosy, it also adds considerable value to your property. People usually install it while getting their new bathroom.

Is underfloor heating cheaper than radiators?

There’s no getting away from the fact that underfloor heating is expensive to install, but what’s more important is that it’s cost effective to run and better for your wallet in the long run. UFH is actually cheaper to run than any radiator that is currently on the market, because the variety of underfloor systems all give out the same heat as a radiator, but do so at a much lower water temperature.

Is it cheaper to run underfloor heating all the time?

It’s not an easy question to answer, but we’d strongly recommend you to leave your underfloor heating on at all times, especially during any cold or wintery times of the year. UFH takes a good while to heat up, so constantly switching it on and off will cause a real waste of energy and ultimately, higher energy costs.

What is the most economical way to run underfloor heating?

To make the whole underfloor heating system more efficient, we advise getting a heating control fitted as part of your package. This will allow the system to keep ticking over until a room drops below your target temp. Some of these controls will automatically drop the temperature through the night as well, so you aren’t wasting any energy when you are asleep.

How long does underfloor heating last?

In order to meet the DIN 4726 industry standards (1), (2), any pipework that is used in an underfloor heating system needs to have a 50 year projected lifespan. Often, manufacturers will go way beyond this, with some systems lasting close to a century or more. For most people, this is a lifetime guarantee, so there’s no need to worry that your system is going to need replacing after a couple of years. Like we’ve said, an underflooring heating system is a serious investment and you should get your money back when it comes to selling your property in the future.
