EPC & Energy
Energy Performance Certificate data for every assessed UK property. Current rating, potential rating, floor area, construction age — and it's completely free. No API key needed.
What's included
EPC Rating →
Current and potential EPC rating (A–G) with numeric efficiency score (1–100) and environmental impact rating.
Floor Area →
Total floor area in square metres as recorded on the EPC certificate. Useful for price-per-sqm calculations.
Construction Age →
Construction age band from the EPC record (e.g. "1930-1949", "2020-2029"). Filter and segment by building era.
Certificate Date →
Last EPC lodgement date — flag expiring certificates (valid 10 years) before they become a compliance gap.
Full Property + EPC →
Get EPC data alongside property details, listings, sales history, and risk scores — all from a single UPRN lookup.
Council Tax Band →
Council tax band (A–H) for any postcode. Pair with EPC data for complete property cost analysis.
