Compare rents, sale prices, market change, activity and observed supply across local authorities. Every reading carries its date, percentile and interpretation boundary.
Latest observation release
The changing layer now has its own clock.
The national Property Atlas remains a dated analytical release. Rental-market observations can now publish independently, with fixed units, quality rates and immutable files.

Working standard
Evidence before estimates.
Every published number carries a definition, a date and a boundary around what it cannot prove.
Read the full method- 01Observe
Record what a source actually shows, with place and time attached.
- 02Normalise
Make dates, prices, geography and property attributes comparable.
- 03Join carefully
Keep possible matches separate until location, imagery or attributes provide enough proof.
- 04Show the gaps
Every result includes its sample size and limitations.
Applied research
From national evidence
to local decisions.
