ESOS Cycle 3 compliance deadline: 5 December 2023. For many UK organisations, the scramble looked familiar. The same last minute data collection exercise that had played out in Cycles 1 and 2, with the same gaps, the same estimated figures, and the same uncomfortable conversations with auditors about what the records could and could not support.

James is energy manager at a mid size facilities services company with operations across fourteen sites in England. His organisation qualified for ESOS well above the employee and turnover thresholds. He had twelve months of advance notice. Six weeks before the deadline, he was still working backwards from utility bills to reconstruct consumption data that should have been available at the press of a button.

The bills covered the main meters. They did not cover sub metered areas. They did not distinguish between process loads and building fabric. The data quality was not sufficient to give his lead assessor the granularity needed to make meaningful recommendations, which is the entire point of the scheme.

Monitor Hut was deployed across the estate in Q1 2024, ahead of the next qualification period. Daily and half hourly metering, site dependent, now flows continuously from all fourteen sites: structured, timestamped, and exportable in the formats assessors actually need.
