UNDERFLOOR HEATING INSTALLERS

What Is Underfloor Heating?

Underfloor heating (UFH) uses a network of pipes or electric mats beneath the floor to distribute warmth evenly across a room – creating gentle, comfortable heat without the noise or bulk of radiators. It operates at lower flow temperatures than traditional radiators, making it ideal for integration with modern, energy-efficient heating systems.

There are two main types:

  • Hydronic (wet) systems – use warm water circulating through pipes beneath the floor

  • Electric systems – employ heating mats or cables installed under the floor surface

Underfloor heating offers responsive, consistent warmth, is ideal for open-plan spaces, and pairs beautifully with renewable and low-temperature heat sources.

Design & Installation

We begin with a site survey – assessing flooring types, insulation levels, heat demand, and existing heating systems. Based on that, we design a bespoke underfloor heating plan using the appropriate layout, pipe spacing, flow circuits, manifolds, and controls.

Whether you’re installing underfloor heating in a new build, renovation, or extension, we integrate it seamlessly into your property, ensuring efficient performance and compliance with building regulations.

Integration & Hybrid Systems

For properties with existing radiators, we design hybrid solutions that combine underfloor heating on lower floors with radiators upstairs. This allows you to enjoy the benefits of UFH in living spaces while retaining conventional heating in bedrooms. We also integrate underfloor systems with air source heat pumps, oil boilers, or other renewable heating technologies.

Servicing, Maintenance & Repairs

Regular maintenance ensures your underfloor heating system operates optimally. We can:

  • Inspect manifolds, flow valves, pipes, and control systems

  • Flush pipes and top up fluid (for hydronic systems)

  • Diagnose and repair leaks, blockages, sensor faults, or circulation issues

  • Adjust settings to improve comfort and energy efficiency

Upgrades & Retrofitting

If you’re upgrading part of your heating system or undertaking a renovation, we can retrofit underfloor heating into existing spaces (where floor depths allow). We work with shallow-profile systems and modern materials to minimise floor build-up while maximising heating performance.
