How much does underfloor heating cost?
Warm water underfloor heating costs as little as £800 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.
Typical system costs
The exact cost of an underfloor heating system will vary depending on the most suitable solution for the project. For example, a standard screed UFH system for a new build project is often cheaper than a retrofit solution where more materials are required.
Cost of underfloor heating in a new build
Screed UFH is a cost-effective heating choice for a new build property that fits neatly into the build schedule. Installation is also quick, which helps to keep costs to a minimum.
In a typical self-build project (such as a detached 3 bedroomed home) with a 100m2 floor area, you could expect a bespoke screed UFH system to cost approximately £2800-£3000, or £30 per square metre, excluding the screed. This would include a unique system design tailored to the property and homeowner’s requirements, the highest quality components and an unrivalled level of customer support for the lifetime of the system. Every project, regardless of size, is handled by qualified and experienced heating experts to ensure the system performs exactly as required.
Cost of underfloor heating in a renovation
More materials are supplied with retrofit UFH systems (such as pre-routed panels or specialist self-levelling compound), so for this reason they tend to cost more than a new build system. Whilst UFH for a renovation might cost more, Nu‑Heat’s award-winning LoPro™ range avoids the time and expense of digging up floors, making UFH a reality for most properties. It also includes everything you need to complete the installation prior to the floor covering being laid – there is no additional cost of screed, for example.
In a renovation project, such as an average Victorian terrace with a downstairs floor area of around 60m2, a bespoke LoPro™10 system would cost in the region of £4500, or £75 per square metre. This would include everything required to install the UFH so that it is ready for the chosen floor finishes, as well as a bespoke system design and an unrivalled level of customer support for the entire lifetime of the system.
Nu-Heat’s LoPro™ systems offer the lowest TOTAL height build-ups on the market of 15mm and 22mm. Once installed, the chosen floor finish – including tiles – can be laid without any worry of deflection that can cause damage to floor coverings such as tiles over time.
Underfloor heating installation costs
Once you have an indication of the price of the system, you also need to consider the cost of having the system installed by a qualified heating and plumbing engineer.
The cost of installation is difficult to estimate as it varies depending on the area of the UK (London postcodes charge more, for example) and the size and type of UFH system being installed. If we take the previous scenario of a new build with a total floor area of 100m2 and choose an installer who charges £30 per hour, you could expect the installation to cost roughly £800.
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.
Warm water UFH 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. Because of this, running costs are often lower than a traditional radiator system and around a third of an equivalent electric UFH system.
