Property boundaries in England and Wales: how to find your boundary lines

HM Land Registry has the extent of a title on file, but ordering an official plan for a quick, casual check is slow and often unnecessary. Search an England or Wales street address on MapMyLot instead and the cadastral extent loads as a highlighted polygon on the map, with area and perimeter in the readout panel - no Land Registry title number and no account needed. England and Wales are part of MapMyLot's combined UK coverage, sourced from HM Land Registry INSPIRE Index Polygons.

What the readout panel shows

The panel above is MapMyLot's parcel readout for a live search - the same layout applies to an England or Wales address: land area in square metres and hectares, perimeter in metres, and, where available for the location, straight-line distance to the nearest high-voltage power line, mapped flood zone, the coast, and the nearest park.

INSPIRE polygons versus a title plan

HM Land Registry's INSPIRE Index Polygons show the general extent of a registered title - useful for a fast, free first look - but they are explicitly not a precise legal boundary. The polygon can differ from the physical boundary shown on the deeds or on the ground, particularly on older titles. For anything with legal weight, order the official title plan from HM Land Registry or engage a chartered surveyor.

Note: INSPIRE Index Polygon data shows the general extent of a title, not a precise legal boundary. For a legally binding determination, order an official title plan from HM Land Registry or engage a chartered surveyor.

Free to check, Pro for unlimited

Five address lookups a day are free, with no account required - enough to check a handful of England and Wales properties. MapMyLot Pro, at A$19.99 a month, removes the daily limit and adds unlimited PDF boundary reports, useful for agents, buyers comparing several properties, or anyone doing repeat lookups. A single PDF report is also available for A$4.99 without a subscription.

INSPIRE Index Polygon data is refreshed on HM Land Registry's own schedule, so a very recently registered title may take time to appear. If a search returns no boundary for a new title, that generally means the registration has not yet propagated to the published dataset rather than an error in the search.

Check an address in three steps

1. Open the map, enter the street address and select the matching result.
2. Confirm the highlighted parcel is the one you meant to check, then read its area and perimeter.
3. Use satellite view for visual context and review the available readouts. If the parcel or figures do not match your documents, investigate the difference before relying on them.

What to do after your first check

Confirm you have the right parcel, then compare its mapped size and shape with the listing or your documents. If you need a copy for your own research, a one-off PDF property report costs A$4.99. For repeated checks, Pro costs A$19.99/month and includes unlimited lookups and PDF reports. Compare the options after checking the address. Reports are informational and do not replace a survey or title search.
