Property boundary maps

OS Partners sell large-scale maps to use for planning permission. For details on legal boundaries, contact HM Land Registry.

OS maps don't show legal property boundaries or ownership of physical features. Our remit is to survey and map the physical features on the ground at the time of survey, not to provide maps showing property boundaries.

To get maps of a house or other property for planning permission and/or submission to HM Land Registry, you can contact an OS partner. Some of our Partners sell large-scale maps for this purpose.

If you are trying to determine who owns an area of land or where a legal boundary exists, you will need to contact HM Land Registry.

HM Land Registry's role in recording boundaries

HM Land Registry will show the extent of the land in a registered title by a red line on the title plan. Where a boundary of the land is not defined by a physical feature on the Ordnance Survey map, HM Land Registry indicates it on the title plan by a dotted line.

England and Wales operates a 'general boundaries' system of land registration. A title plan with 'general boundaries' shows the boundary of a property in relation to a given physical feature on the ground such as a wall or hedge as identified on the Ordnance Survey map.

The red edging on a HM Land Registry title plan is therefore not definitive as to the precise position of the boundaries. For this reason official copies of title plans carry the following warning:

This title plan shows the general position of the boundaries: it does not show the exact line of the boundaries. Measurements scaled from this plan may not match measurements between the same points on the ground.

This is a clear statement that HM Land Registry is unable to tell you precisely where a property boundary is located.
