2.1 What we've built
Thermal Atlas turns a council's existing EPC records and a single aerial thermal survey into a street-by-street retrofit plan — which homes to insulate, in what order, at what cost — without a physical survey of every property. The core is a heat-loss model trained on 1.2 million UK dwellings, calibrated against measured energy bills.
2.2 Why it's novel
No UK provider prioritises retrofit across a whole housing stock from remote data — incumbents survey door-to-door, at roughly £180 per home. Our remote method is the subject of a UK patent application (GB 24…), and the calibration dataset is a defensible trade secret.
