Survey once. Design together. Care beyond installation.

A guided self-survey captures your priorities, energy use, rooms, windows, airflow, electrical readiness and practical constraints before a professional visit.

One coordinated improvement plan manages the interfaces between fabric and moisture, airtightness and ventilation, heat loss and heating, plus electrical capacity, generation and controls. We recalculate before selecting equipment rather than adding disconnected percentages.

Qualified specialists and any required statutory roles remain distinct, but work from one agreed design and one GridSync Property Passport. You receive one named accountable route rather than being left to coordinate trades.

Before work starts, named duty holders agree the construction plan, task controls, access, resident welfare and continuity of essential services. Daily make-safe checks, stop-work authority and evidence gates protect residents, workers and the building.

Every change is agreed, every system commissioned, and every handover recorded. Follow-ups at 2, 6 and 12 weeks lead into a meaningful seasonal review, with measured operation kept separate from the original estimate. The developing Home Energy Model provides a useful half-hourly assessment direction, while real operation remains a separate evidence track.
