Sold prices: HM Land Registry Price Paid Data, the official UK government records updated monthly. Sample uses the 30 most recent registered transactions in the postcode area.
Crime: Police UK street-level crime data, covering a 1-mile radius from the NP12 postcode centroid for the most recent month available (typically 2 months behind).

EPC: opendatacommunities.org, the official Energy Performance Certificate register for England and Wales. Aggregate stats from up to 30 most recent certificates in the postcode. For Scottish postcodes we use Scottish EPC Register lodgements, aggregated to a council-level band distribution (Q2 2025 to Q1 2026). For Northern Ireland we use the NISRA Census 2021 EPC-band classification of every household, aggregated by council (Census 2021).
