Underfloor Heating Retrofit Checklist

Retrofitting underfloor heating can transform comfort, but planning matters. The first step is understanding available floor build-up and whether a low-profile system is needed.

We then assess room heat loss, floor finishes, and control zones. Kitchens, extensions, and open-plan living areas often need different loop lengths and controls than bedrooms or hallways.

Hydraulic balancing and commissioning are just as important as the install itself. Without proper setup, even high-quality systems can underperform.

Before starting a retrofit, gather property drawings if possible and list any future renovation work. This helps coordinate heating design with wider building plans.
