How much does underfloor heating cost?
Warm water underfloor heating costs as little as £400+VAT for a 20m² room, but price varies by project. It is an affordable heating solution that is around 25% more efficient than radiators, so savings can also be made on heating bills.
How much does underfloor heating cost?
Warm water underfloor heating is a more efficient, eco-friendly alternative to radiators – and it costs less than most people expect. Cost comes down mainly to the type of project: in a new build the pipework often sits in the screed, which is already part of the build, while a retrofit system uses purpose-made panels or levelling compound over your existing floor, so more is included in the price. The prices below are for the system itself; installation is quoted separately by your heating engineer.
UFH costs in a new build
Screed underfloor heating is the go-to choice for a ground-floor new build or extension, laid within the screed as the build progresses.
- Installed at first fix
- Fits into the build schedule
- Ideal partner for a heat pump
From £20 m²

Cost of installing underfloor heating
Once you have an idea of the system price, you also need to consider the cost of having the system installed by a qualified heating and plumbing engineer.
The cost of installing underfloor heating is difficult to estimate as it varies depending on the area of the UK and the size and type of UFH system being installed. We would normally expect the installation cost to be roughly 40-50% of the cost of the system.
In straightforward or smaller projects, it is possible to install the fixing system and tube yourself, or have a builder do this, before getting the plumber in to set up the manifold, connect it back to the boiler and commission the system.

Underfloor heating running costs: Warm water Vs Electric
| The running costs have been based on a standard electricity price of £0.31 per kWh and a domestic natural gas price of £0.07 per kWh (correct as of Aug 2026). | |||
Warm water underfloor heating running costs
Warm water underfloor heating is a highly efficient heating system – around 25% more efficient than radiators when paired with a modern condensing boiler and up to 40% more efficient when running from a heat pump (including air source heat pump or ground source heat pumps).
Because of this, running costs are often lower than a traditional radiator system and around a third of an equivalent electric UFH system.
Electric underfloor heating running costs
Electric underfloor heating running costs can be three to four times more than a warm water UFH system, or a radiator system, that is paired with a gas boiler. This is simply because electric tends to cost far more than natural gas per kWh.
Electric UFH is a good option for small spaces, like bathrooms or kitchen refurbs, where it can warm hard floor finishes. It is rarely used to heat an entire property because of the associated running costs.

Underfloor heating cost FAQs
Is underfloor heating expensive to run?
No. Because warm water underfloor heating distributes heat at a lower temperature and more efficiently into a room than a radiator system, it can be cheaper to run. Electric underfloor heating, however, is likely to be far more expensive to run due to the higher cost of electricity, this is why we would only ever recommend using electric underfloor heating to heat a small area.
How much does it cost to install underfloor heating?
Exact installation costs will vary according to the specific requirements of your project. If you have plans for a project you are working on, give us a call and we can put you in touch with one of our Registered Installers who can give you a full installation quotation.
How much is underfloor heating per m2?
Cost per m² can start from as low as £20/m². However, this can vary depending on many different factors. For an exact cost per m², speak to one of our Account Managers who can give you a bespoke quotation based on your plans.
How much does water and electric underfloor heating cost to run?
As a rough guide, you can expect electric underfloor heating to cost three times as much to run as warm water underfloor heating. This is because electricity costs considerably more than gas.
Is underfloor heating cost efficient?
Yes, as underfloor heating gently emits heat across a large surface area, it can utilise a lower flow temperature than radiators which can make it more cost efficient, especially when paired with a low temperature heat source like a heat pump.
