Underfloor heating is often seen as a luxury feature reserved for ground-floor kitchens and bathrooms. But what if you’d like the same comfort in your upstairs bedrooms or bathrooms? Is it even possible – and is it worth doing?
The short answer is yes, you can have underfloor heating upstairs. In fact, with modern systems and proper installation, it can be an efficient and comfortable option for almost any floor in your home. Here’s what you need to know.
How underfloor heating works
There are two main types of underfloor heating:
- Electric (dry) systems – use electric cables or mats fitted beneath the floor covering.
- Water (wet) systems – circulate warm water through pipes connected to your boiler or renewable heating system.
Both options work by gently radiating heat from the floor upwards, creating an even warmth throughout the room. Unlike radiators, there are no cold spots or draughts.
Can it really be installed upstairs?
Yes. Underfloor heating can be fitted on upper floors just as effectively as the ground floor. The key difference is the type of system and how it’s installed:
- Electric underfloor heating is lightweight and straightforward, making it ideal for upstairs rooms with less available height.
- Water-based underfloor heating is possible too, but requires more planning because of the additional pipework and floor depth needed.
With the right design, either system can work well upstairs.
Benefits of upstairs underfloor heating
Adding underfloor heating to bedrooms, bathrooms, or loft conversions offers several advantages:
- Consistent comfort – No more cold floors on winter mornings. Bedrooms and bathrooms feel cosy from top to bottom.
- Extra space – Removing bulky radiators frees up wall space, allowing for more flexible room layouts.
- Even heat distribution – Radiators heat unevenly, with warm air rising to the ceiling. Underfloor heating provides steady, uniform warmth.
- Energy efficiency – Because the system runs at lower temperatures than radiators, it can be cheaper to run (especially with modern boilers or heat pumps).
- Ideal with renewables – Heat pumps, in particular, pair perfectly with underfloor heating because they both work best at low water temperatures.
Things to consider before installation
While upstairs underfloor heating is possible, there are some important factors to think about:
Floor construction
- Timber floors: Common upstairs, but may require strengthening to carry the extra weight of a water system.
- Concrete floors: Rare upstairs but make installation simpler.
Floor coverings
Carpet, vinyl, laminate, and tiles can all be used with underfloor heating, but thickness matters. Very thick carpets may reduce efficiency, while tiles and stone conduct heat especially well.
Height build-up
Water systems need pipework and insulation, which can raise the floor level slightly. Electric mats are much thinner and often preferred upstairs to minimise height changes.
Installation disruption
Fitting water underfloor heating upstairs is usually easier during a refurbishment or new build, as floors need to be lifted. Electric systems can sometimes be retrofitted with less disruption.
Costs and efficiency
- Electric systems tend to be cheaper to install but more expensive to run in the long term.
- Water systems cost more upfront but are cheaper to run, especially with an efficient boiler or heat pump.
Many homeowners choose electric upstairs for smaller rooms (like bathrooms) and water systems downstairs or in larger spaces.
When underfloor heating upstairs is a great idea
- Bathroom upgrades: Adds luxury and eliminates cold tiles.
- Bedroom renovations: Frees up space and creates consistent comfort.
- Loft conversions: Ideal for new builds or renovations where radiators would take up valuable wall space.
- Homes with heat pumps: Maximises efficiency by running at lower water temperatures.
Professional installation is key
As with any heating system, correct installation is critical. Poorly fitted underfloor heating can cause uneven heating, floor damage, or inefficiency.
