Reduce your energy bills with underfloor heating installation

At Lewington Heating, we’ve been installing underfloor heating water systems alongside our award-winning heat pumps ever since we first launched our Lewington Renewable division back in 2000. We pride ourselves on installing and integrating underfloor heating with your hot water system, whether it’s renewable or non-renewable. Either way, switching to underfloor heating is financially beneficial as it’s more efficient than a traditional radiator-based system.

“We’re really proud to be endorsed by Which as being a Trusted Trader. To become one of only a select few within our area is testament to our commitment to providing a friendly, efficient and cost-effective service to homes within the Leicestershire area.”


Underfloor heating is a more efficient alternative to a radiator system, which is why at Lewington Heating we install underfloor heating systems alongside many of our renewable options. By heating your home through the floor, you avoid cold spots and save yourself vital space within your home while creating a cosy and more streamlined, radiator-free space.

Our underfloor heating fitters can integrate your system with air source and ground source heat pumps to maximise the efficiency of renewable energy. However, although these two systems are often installed simultaneously, your new underfloor heating system can be integrated with any home heating source.


An underfloor heating water system is an efficient heating solution for any home, particularly new builds or extensions. Its space-saving qualities makes it an ideal heating solution for smaller rooms too.

Pipes are installed underneath your floor, heating your home from the ground up. These pipes run across the floor at a relatively low temperature which requires less energy than a radiator system and also has the added bonus of ensuring there are no cold spots in your room.




Hydronic or wet underfloor heating works by installing a series of pipes underneath your finished floor. The pipes utilise the central heating water that already supplies the heating system. The pipes work as a closed loop which flows constantly between a manifold and the floor, ensuring constant heat coverage.

There are two common ways of installing underfloor heating. Layering of pipes within the concrete floor screed is usually done during the construction process and offers an easier solution than radiators.

For existing rooms, we will install an ‘overlay’ system, which involves laying an 18mm thick profiled board on top of the existing floor. The pipes are inserted into the pre-formed grooves then covered by either a self-levelling compound or 9mm ply, before the final floor covering of your choice.

The temperature of the underfloor heating water system can be easily controlled by a Smart thermostat in your home, making it simple to maintain and adjust to the perfect temperature.


There are many benefits of installing wet underfloor heating. These include:

  • Creation of a silent, invisible source of heat
  • No cold spots or chilly corners
  • Takes up no space within the room itself
  • Low maintenance
  • 0% VAT rate when installed alongside a heat pump
  • Versatile fitting for any shape room
  • More energy efficient than radiators
  • No pollutants
  • Can be integrated with renewable energy sources


Underfloor heating is not part of the UK government’s renewable compensation scheme. However, it can be integrated with air source heat pumps, ground source heat pumps or solar hot water panels which are all eligible technologies for the Boiler Upgrade Scheme.

At Lewington, we often install these technologies simultaneously, as customers want to make sure that their renewable energy will be used in the most efficient way possible. Many customers put the savings they have made from investing in renewable technologies towards new underfloor heating systems, creating a stress-free integrated heating solution.

The UK Government offers a variety of grants and financial incentives to encourage UK homes to swap to renewable heating systems.

    No, as a company we only install wet systems. Electric systems tend to be a tile warmer, not a sole source of heat for a room.

    No, a well designed wet underfloor heating system can be your sole source of heat, so no need for unsightly radiators.

    Underfloor heating provide a low temperature background heat. It is not as responsive as a radiator system but runs for longer period, just topping up the temperature as required.

    Yes, you can install an “Overlay” system, which is an 18mm board with profiled grooves to take the pipes. This board is then either covered with self levelling compound or 9mm ply before your final floor covering is laid. This option typically brings up you floor levels by about 28mm.

    Underfloor heating is ideal for a new build or extensions as the pipes can be laid into the floor before the concrete is poured over.
