Underfloor heating turns a cold floor into the radiator — even, gentle warmth with no radiators on the walls. We design and fit wet underfloor heating across Swansea, usually as part of an extension or renovation.

Where underfloor heating works best
Wet underfloor heating — warm water in pipes under the floor — comes into its own in new floor build-ups: extensions, open-plan kitchen-diners, and renovations where the floor is coming up anyway. Across Swansea, from Sketty and Uplands to Morriston and the Mumbles road, that is usually where we fit it.
Retrofitting under an existing floor is possible with low-profile overlay systems, but the floor height, insulation and heat output all need thinking through. Chris will tell you honestly whether your room suits it.
How it works with your boiler
Underfloor heating runs at much lower water temperatures than radiators, which suits modern condensing boilers well — cooler return water means the boiler condenses more and runs more efficiently. The system connects through a mixing unit that blends the water down to the right temperature, with its own controls for the rooms it serves.
Design matters more than the kit
Heat loss calculated for each room, not guessed
Pipe spacing set for the floor finish — tiles conduct better than wood
Insulation below the pipes so the heat goes up, not down
Manifold position planned for access and neat pipework
Controls that let each room run its own schedule
Timing in a renovation
Underfloor heating goes in at a specific moment: after the floor structure is ready and before the screed or final floor. If you are planning an extension or a big refurb in Swansea, involve us early — a conversation at plan stage costs nothing and avoids the expensive version where the floor build-up has to be redesigned. Our underfloor heating cost guide explains what drives the price.
Underfloor heating vs radiators
It is not either-or. Many Swansea homes run underfloor heating downstairs in the open-plan space and radiators upstairs, off the same boiler. Our central heating and radiator installation pages cover the radiator side, and our underfloor heating page has the full detail on the systems themselves.

Common questions
Underfloor Heating FAQs
Clear answers before you arrange a visit.
Can underfloor heating go in an existing room?+
Sometimes, using low-profile overlay systems, but floor height, insulation and heat output all need checking. It is easiest in extensions and renovations where the floor is coming up anyway.
Is underfloor heating expensive to run?+
It runs at low water temperatures, which suits condensing boilers. Running cost depends on the room, insulation and how you use the controls — not just the system itself.
Can it work with my existing boiler?+
Usually yes, through a mixing unit that blends the water down to the lower temperature underfloor heating needs. Chris checks compatibility at the survey.
Do you cover the whole of Swansea?+
Yes — from Sketty and Uplands to Morriston and Mumbles, Swansea is within our travelling area for planned projects.
