Direct answer
What this service involves
Wet underfloor heating distributes heat across a large floor area, allowing lower water temperatures than many radiator systems. That can pair well with heat pumps when the floor build-up, spacing, controls and room heat loss are designed together.
When it may suit your home
Floor construction, insulation, coverings, available build-up, response time and room heat loss determine the right layout. It is often easiest in new floors but retrofit systems can be assessed.

Underfloor heating: frequently asked questions
Answers are shown in full so they remain useful and accessible. Property-specific decisions still require survey evidence.
Browse the full FAQ library →Can underfloor heating replace radiators?+
It can in rooms where the available floor output meets the design heat loss.
Does it work under every floor finish?+
Many finishes are compatible, but thermal resistance and manufacturer limits must be checked.
Is it suitable upstairs?+
Yes in suitable constructions, using a system selected for weight, build-up and output constraints.
What information helps before a underfloor heating visit?+
Share the property type, current heating fuel, recent energy use where available, comfort problems, planned building work and photographs of the existing equipment. This helps us identify the right survey or diagnostic visit.
How is underfloor heating priced?+
A reliable price follows a defined scope. Equipment, access, diagnostic or heat-loss work, emitter and cylinder changes, electrical work, controls, commissioning and aftercare can all affect the quotation.

Design evidence
What we check before recommending underfloor heating
Renewable heating works best when the recommendation follows measured evidence. We look at the building fabric, room-by-room heat demand, the condition and output of radiators or floor circuits, water temperatures, pipe sizes, hot-water storage, controls, electrical supply, access and where equipment can be serviced safely. For a fault or maintenance visit, the same whole-system view helps separate a component problem from an operating or design symptom.
The proposal should state its assumptions, including the design outside temperature, intended flow temperature, expected emitter output, hot-water strategy and any enabling work. Where information is uncertain, we explain what must be measured or confirmed rather than hiding the uncertainty inside a product allowance.
Homeowner decisions
Questions worth resolving early
Think about the rooms that are difficult to heat, how the household uses hot water, acceptable disruption, future extensions, insulation plans and the space available for cylinders, controls or outdoor equipment. These details can change the sensible sequence of work and prevent avoidable alterations later.
Performance and running cost cannot be guaranteed from a product label. The useful comparison is a written system design with clear heat-demand and tariff assumptions. We can also explain where the Boiler Upgrade Scheme may apply, while keeping grant eligibility separate from the engineering decision.
