Underfloor Heating Systems for New Builds
The right system for your new build.
Installing underfloor heating in a new build gives you the widest choice of systems and the cleanest installation conditions. With the floor structure open before finishes go in, there are no constraints on build-up height and no risk of disruption to finished rooms.
The two primary systems we design, supply and install in new build projects are detailed below. Which one is right for your project depends on factors including floor construction, available build-up height and your build programme timeline – all of which we assess as part of our free design service.
Pipe in ScreedThe standard for new build UFH – and for good reason.
Pipe in screed is the most widely used underfloor heating system in new build projects and remains the most cost-effective, highest-performing solution where a screed floor is being laid.
How it works: UFH pipework is clipped onto insulation laid directly on the concrete sub-floor. Liquid screed – typically 50–65mm thick – is then poured on top, embedding the pipes completely. Once dried and cured, the screed acts as a thermal mass, absorbing heat from the pipes and radiating it evenly upward into the room.
Why choose pipe in screed:
One thing to plan for: Screed requires several weeks to dry before floor coverings can be laid. This must be factored into your build programme. We’ll advise on timescales as part of your project consultation.
Best for: New build properties with a concrete sub-floor where a screed finish is planned and the build timeline allows for the curing period.
RetroTherm® FLO (New Build Specification)Where floor build-up height or build programme is a consideration.
Although RetroTherm® FLO is most commonly associated with retrofit applications, it is equally suited to new build projects where minimising floor build-up or avoiding the screed drying period is a priority.
How it works: RetroTherm® FLO is a multi-directional panel system installed directly onto the concrete sub-floor. Using 12mm pipe, it achieves a maximum build-up of less than 20mm – significantly less than a conventional screed system – while still delivering excellent heat output.
Why choose RetroTherm® FLO in a new build:
Best for: New builds where floor height relationships are critical, where build programmes are tight, or where the screed drying period would cause delays.
