UK House Price Monitor
A database-free search and trend viewer for HM Land Registry Price Paid Data.
Visit projectUK House Price Monitor explores England and Wales Price Paid Data directly from HM Land Registry, without maintaining a local database. It runs within the constraints of Vercel Hobby while still exposing individual transactions.
Searches can be narrowed by date, region, and postcode prefix, with both raw transactions and aggregate trends in the result. The API limits date windows, page sizes, and result counts, retries slow upstream requests, and marks partial responses rather than presenting incomplete data as final.
How it works
- Fetches live from HM Land Registry, with no ETL pipeline or database
- Validates and bounds queries before they reach the upstream service
- Falls back when upstream endpoints are busy
- Returns latency, warnings, and partial-result metadata
- Caches common queries differently from high-variance searches
