How to read the price and data coverage
The median is the middle transaction price for undeveloped land sold over the last 12 months. We include full-property sales on the open market and exclude roads, shares and packages without a price allocated to the plot. An exact ranking position requires at least 30 deeds, at least 80% coverage, a relative 95% confidence-interval width of at most 50%, and no quality flags. From 10 deeds we show a comparison band; 1–9 deeds give an informational price only. Missing prices are not estimated. Agricultural land has a separate median. Check planning documents for the permitted use of a specific plot. 2026-10-24T06:28:58+00:00.
