The challenge
An ageing distribution system with no metering granularity, no spare capacity and an EPC rating blocking the owner's ESG commitments.

Net-zero-ready headquarters retrofit
A full electrical retrofit of a 1990s headquarters: new boards, circuit-level metering, rooftop PV and 60 charging bays.
Engineering design
Complete switchboard replacement with selective protection, per-circuit metering across 11 floors, 320 kWp rooftop PV, 200 kWh storage and 60 charging bays with dynamic management.
Installation
Fourteen months, floor by floor, with the building fully occupied throughout.
“Circuit-level data changed our behaviour before the solar was even switched on. We found 80 kW of standby load.”
