Case Study: Department of Energy and Climate Change (DECC) achieves consistent cross‑referencing of property data to inform energy policy with Ordnance Survey AddressBase Premium

Department of Energy and Climate Change - Customer Case Study

The Department of Energy & Climate Change (DECC) needed to combine property and energy data from multiple sources to inform policy but faced inconsistent address information, no single unique identifier, and repeated rematching of records. Working with Ordnance Survey and using its AddressBase Premium product (and the UPRN it provides), DECC developed the National Energy Efficiency Data‑Framework (NEED) to create consistent cross‑referenced datasets.

Ordnance Survey’s AddressBase Premium allowed DECC to address‑match once and assign a UPRN to each record for repeated use across analyses, forming the backbone of NEED. As a result, NEED has informed Green Deal and ECO insulation savings estimates, fuel poverty and heat policy (consumption by income, tenure and property attributes), DECC’s Heat Map and Energy UK’s Compare My Energy tool—driving increased collaboration, reduced duplication and measurable policy insights.
