How to use
- Enter a postcode or street address and click Find Address (counts toward your shared daily search quota).
- On the map, choose Length (open distances) or Area (closed plot).
- Turn on the ruler, then click points on the map — drawing lengths and areas is free and does not use quota.
- Length: click the last point or press Esc to finish — no area is calculated.
- Area: click corners, then the green start point to close the shape (perimeter + area).
- In the log, click a row to expand each segment (P1→P2, P2→P3, …). Copy or clear as needed.
Address search shares the same daily quota as EPC, flood, crime and other lookup tools. Map drawing is unlimited. Approximate measurements for planning — not a survey.
Measuring the plot is a useful first check. For a full property report with sold prices, EPC, flood risk and crime, see homebuyerreport.co.uk.
