About BoundaryFinder
We help UK property owners and buyers understand exactly where their property boundaries are using official Land Registry data, satellite imagery and GPS coordinates.
What We Do
BoundaryFinder generates instant property boundary reports for any registered freehold property in England & Wales. Our reports combine data from HM Land Registry, Ordnance Survey, Environment Agency and Google Maps to give you a complete picture of your property boundaries.
Our Data Sources
All our data comes from official UK government sources, licensed under the Open Government Licence:
- HM Land Registry INSPIRE Index Polygons — registered title boundaries for 26 million+ properties
- Ordnance Survey Open UPRN — 40 million+ property addresses
- OS OpenMap Local — building footprints across Great Britain
- Environment Agency LiDAR — 1-metre terrain elevation data
Understanding UK Boundaries
Unlike some countries, the UK uses the general boundary principle. Under the Land Registration Act 2002, the boundary shown on a title plan indicates the approximate position of the boundary — not the exact line. Physical features on the ground (walls, fences, hedges) typically define the actual boundary.
Our GPS coordinates are derived from the registered title plan and are a useful guide for understanding your property extent, but they should not be treated as a legally definitive boundary line.
