Pros and cons of underfloor heating

This guide is intended to provide general guidance only. It is not intended to give you advice on your personal financial circumstances. You should seek independent professional advice if you’re unsure about anything mentioned in this guide or what choices to make.

Underfloor heating is a great way to keep your home warm. It’s lovely to walk on, it distributes heat evenly around each corner of the room, and it frees your walls from radiators, making more space for paintings, shelf units or even picture windows - or allowing you to create a minimalist look if you wish.

However, it can also be very expensive to install, particularly in older houses, so you may need to think long and hard before making a decision.

Why don’t more people have it in their homes? We look at the pros and cons to help you decide whether it’s right for your property.

What are the good things about underfloor heating systems?

So what’s not so good about it?

Which is the best underfloor heating for my home – electric or water based?

You can choose either electric underfloor heating (known as a ‘dry’ system) or water-based heating (this is known as ‘wet’ heating). Our table lets you look through the pros and cons of each, to help you decide which might suit you better.

 

What will underfloor heating cost to install?

Installation costs can vary hugely, depending on whether you choose an electric or water-based system, the number of rooms you want to heat, whether you’re fitting a new-build home, extension or an older building, and what kind of flooring you have.

Electric systems

Prices for roll-out mats for underfloor electric heating start at about £180 for 10 square metres*. Plus you’ll need to add in the costs of insulation board, screed and heating controls. You’ll also need to pay a qualified electrician to link it to your electricity supply (see ‘Can I install it myself?’ below).

Water-based systems

The price of installing a ‘wet’ system can vary according to factors like whether the room you’re heating is on the ground floor, or how close it is to the boiler. However, it will almost certainly be more expensive than laying electric mats for a ‘dry’ system.

Do I need a timer?

Yes – underfloor heating takes a while to get going, so you’ll need to set the timer to get it started in good time before you want to enjoy its warmth.

Can I install it myself?

Before you invest in any underfloor heating equipment you should consult a specialist to help you decide which system is right for your home. They will also explain the difficulties and costs involved if you want to install it yourself.

It’s possible to carry out electric underfloor heating installation yourself if you’re confident with DIY techniques. However, if you choose a water-based system you will need a qualified professional to lay the pipes and connect them to your boiler. They will also need to lay insulation and screed.

Whichever system you choose, it should be linked to the electricity supply by a qualified electrician, who will also need to connect a sensor that works the thermostat.

How else can I make my home warmer?

Insulation is key – if you insulate your roof and walls and improve your heating system, your home will be warmer and you could save around £300 a year. What’s more, you’ll cut your home’s carbon dioxide (CO2) emissions by around 1.5 tonnes – so you’re helping the planet, too.
