Underfloor Heating: Types, Costs, and Installation

Why Underfloor Heating?

Underfloor heating (UFH) distributes heat evenly across the entire floor surface, creating a comfortable warmth from the ground up — without the temperature stratification or cold spots associated with radiators. It's also invisible, freeing up wall space, and pairs exceptionally well with air source heat pumps.

The Two Types of Underfloor Heating

Wet (Hydronic) Underfloor Heating

Wet UFH uses warm water pumped through a network of pipes embedded in or clipped to the floor. It connects to your boiler or heat pump as part of the central heating system. Wet UFH is the most energy-efficient option and is ideal for new builds and major refurbishments. It operates at low flow temperatures (30–45°C), making it the perfect companion for air source heat pumps.

Best for: New builds, extensions, ground floors, heat pump installations.

Cost: £50–£100 per m² installed, depending on floor type and complexity.

Electric (Dry) Underfloor Heating

Electric UFH uses heating mats or cables laid beneath the floor covering. It's quicker and cheaper to install but more expensive to run due to electricity costs. Best suited to smaller areas such as bathrooms or kitchens.

Best for: Bathrooms, small areas, retrofits where wet UFH isn't practical.

Cost: £15–£30 per m² for materials, plus installation.

Floor Coverings

Wet UFH works with most floor coverings, though thermal conductivity matters. Stone and ceramic tiles are ideal. Engineered timber works well. Carpet is less effective and some solid timber floors are unsuitable — always check the manufacturer's guidance.

Thermostatic Controls

Each UFH zone should have its own thermostat for efficient control. Smart thermostats allow scheduling and remote management.
