Underfloor heating cost guide
Compare indicative supply-only costs for electric and water underfloor heating systems, including the components that can change the final material price.
Our electric systems typically cost £25–£55/m², in-screed water systems £10–£35/m², and low-profile water systems £35–£75/m², including VAT.
Supply-only costs at a glance
Indicative supply-only prices per m² of heated area, including VAT. Installation, floor preparation and final floor finishes are not included.

Understand the options
Compare where each system fits and the cost trade-off to consider before ordering.
A responsive, low-profile route commonly used for individual rooms and renovation projects.
Cost consideration: Lower purchase cost, but running cost depends heavily on the electricity tariff and usage.
A planned warm-water system for new floors, extensions and larger whole-home projects.
Cost consideration: Economical for larger areas, but requires planned screed and additional controls.
Overlay boards carry the heating pipe above a suitable existing structural floor while controlling build-up.
Cost consideration: Reduces floor disruption, but overlay boards increase material cost.
The complete material cost depends on more than the heating element alone.
Specialist boards, membranes and fixing systems change the material cost per square metre.
Permanent fixtures and fixed units reduce the area that can be heated and should be excluded when sizing.
More zones require additional thermostats, actuators, wiring centres or control components.
The subfloor, insulation and required covering layers determine which preparation products are needed.
Manifolds, pumps, sensors and other essential components vary with the selected system and project design.
Running cost depends on room heat loss, insulation, controls, energy tariff and how the system is used.
Example material budgets
Three worked examples using current Uheat product prices, including VAT. Water examples use a single thermostat for one heating zone; additional room zones and controls are priced separately.

Your quotation itemises the selected heating system and every included component. Installation labour, floor preparation, electrical or plumbing work and final floor finishes are excluded unless clearly stated.
Use the usable heated floor area, excluding permanent fixtures and fixed units where heating cannot be installed. The room-size calculator can help you establish a planning figure before requesting a quote.
No. Uheat supplies underfloor heating systems and components. Installation, floor preparation, screeding and final floor finishes are arranged and priced separately.
Running cost depends on the room heat loss, insulation, controls, energy tariff and how the system is used. A material price alone cannot determine the final running cost.
