Underfloor heating has been used in the UK for over 40 years and is a proven,
low-carbon heating solution for modern homes. It delivers comfortable, even warmth across the entire room while operating at much lower temperatures than traditional radiators.
Water underfloor heating is highly energy-efficient, helping to reduce heating bills while maintaining excellent comfort levels. By heating from the floor up, underfloor heating eliminates cold spots and creates a more consistent indoor temperature.
As trusted underfloor heating suppliers, we install systems that maximise efficiency while preserving your home’s space and design. With no radiators on the walls, underfloor heating allows for greater freedom in room layout and a clean, modern finish.
We’ve been supplying underfloor heating, heating controls, pipework, and renewable energy solutions to our satisfied customers since 2004.
We’re a specialist, independent company, which means we can work with you to find the best solution for your project without being limited to a single brand or manufacturer.
Our team can call upon over forty years of experience when selecting and designing your bespoke system, as we were directly employed and trained by the UK underfloor heating pioneers of the 1970s.
At Radiant Control, our range of in-base underfloor heating systems are designed to distribute heat evenly across the floor, which reduces the amount of energy needed to heat the space where they are installed. This can result in lower energy bills and deliver a more sustainable heating solution.
Installed beneath the floor, in-base systems don’t take up valuable wall or ceiling space. This allows for more flexibility in the design and layout of rooms in your project.
At Radiant Control, our retrofit underfloor heating systems are designed to be simple to install and require minimal maintenance, making them a convenient and cost-effective heating solution. They distribute heat evenly across the floor, providing consistent and comfortable warmth throughout the room.
Our retrofit systems can be installed in a variety of settings, from residential homes to commercial buildings, and can be easily integrated into existing heating systems, making them a flexible choice for both new build and retrofit projects.

Yes. Water (hydronic) systems are typically 3 to 4 times cheaper to run than electric underfloor heating systems. Because wet UFH connects to a gas boiler or heat pump, it utilises energy priced significantly lower per kWh than direct grid electricity.
Electric UFH is ideal for small single-room retrofits (like a 4m² ensuite) where low floor build-up height and cheap installation are priorities, whereas water UFH delivers the lowest running costs for whole-house installations, open-plan extensions, and new builds.
Yes, wet underfloor heating is up to 25% more energy-efficient than traditional radiator systems. Radiators rely on high water flow temperatures (60°C–70°C) to circulate heat via high-level convection, whereas underfloor heating covers a massive surface area and operates at low water temperatures (35°C–45°C).
This produces an even radiant heat profile across the entire room with zero cold spots and makes wet UFH the ideal emitter to pair with low-temperature Air Source Heat Pumps (ASHPs).
Screed systems embed the pipework directly into sand-and-cement or flowing screed, making them ideal for new builds and major ground-floor extensions with plenty of floor height available.
Low-profile overlay and retrofit systems (such as routed chipboard or cover board systems) are laid directly over existing subfloors with minimal build-up height, making them perfect for renovations and upper-floor joist installations.
Absolutely. Because wet underfloor heating covers a large surface area, it operates efficiently at lower water temperatures (35°C–45°C), making it the ideal heat emitter to pair with low-temperature heat pumps.
We specialize in sizing pipework, manifolds, and heat exchangers to maximise heat pump seasonal efficiency.
Wet underfloor heating typically takes 1 to 3 hours to heat up from cold depending on your floor construction. Screed systems take longer to heat up because they warm the surrounding concrete slab, but they hold and radiate that thermal energy for hours after turning off.
Ultra-thin overlay or low-profile panel systems heat up much faster, usually within 30 to 45 minutes.
In cold weather, it is most efficient to leave wet underfloor heating running continuously at a constant temperature or set back slightly (e.g., lowered by 2°C–3°C overnight).
Because the system heats a large surface area at lower temperatures, reheating a cold thermal floor slab from scratch consumes significantly more energy than maintaining a steady setback level.
No. Provided your property meets current UK Building Regulations for insulation and the system is sized correctly across at least 80% of the open floor space, water underfloor heating provides 100% of the space heating required, allowing you to completely remove wall-mounted radiators.
Porcelain or ceramic tiles and natural stone are the absolute best options because they have low thermal resistance and conduct heat instantly. Luxury Vinyl Tile (LVT), engineered wood, and laminate also work brilliantly provided they are rated up to 27°C. C
arpet can be used, but the combined tog rating of the carpet and underlay must not exceed 2.5 Tog to avoid trapping the heat.
