Initial survey and design
- Survey Stage — For a high-profile underfloor heating contract in Camden, London covering 800 apartments across two separate blocks, our survey stage established the technical and logistical foundations for a successful delivery. Beginning with architects’ floor plans, we performed detailed heat-loss calculations for every apartment typology and translated those results into bespoke underfloor heating layouts that accounted for varied floor finishes, room usage, and occupant comfort criteria. Those initial designs were validated and refined through thorough site surveys, laser-checked measurements, and a series of collaborative meetings with the main contractor, M&E consultants and architects to resolve interface issues, tolerance constraints and service-routing challenges. We developed phased material supply plans and installation sequences to match the contractor’s program, specified controls and manifolds for performance and maintenance access, and produced installation drawings and handover documentation. To ensure quality on site, we delivered tailored training sessions for labourers on best-practice installation and wet-system protection, and coordinated pre-commissioning checks so that commissioning could be completed efficiently post-installation, minimizing snagging and ensuring systems met design performance.
Underfloor heating solution
- For the underfloor heating, we designed and supplied a screed-and-staple system using 16 mm PERT-a-PERT pipe, spaced at 175 mm centres due to the building’s excellent heat-loss performance. The system is controlled by Heatmiser neoStats and dedicated wiring centres. We coordinated delivery schedules with the main contractor and securely stored all equipment at our headquarters, provided on-site training and commissioning, and supplied each apartment with a tailored handover pack for the main contractor. All commissioning and installation documentation was uploaded to a bespoke CRM we developed for the contractor, giving them 24/7 access to records.
