API keyJSON

Get ENERGY field group data for a property by UPRN. Provides energy efficiency ratings, consumption and running-cost estimates, assessment dates, and up to five recommended improvements (IMP_1–IMP_5) — with confidence scores and modelled flags on the key fields.

Purpose

  • Energy performance visibility — current and potential efficiency, consumption and running costs.
  • Retrofit planning — costed improvement recommendations with potential ratings and savings.
  • Compliance & eligibility — EPC-style ratings and assessment dates for regulatory and lending checks.
