FAQ

Answers.

Where does the title and ownership data come from?

Green circular button with a white down arrow inside.

We draw on registered title and ownership data covering England and Wales — property classifications, ownership, tenure and registered boundary geometry — unified into one consistent API.

Which areas are covered?

Green circular button with a white down arrow inside.

No. API access is offered as a standalone, separately-priced service. A platform licence does not include API access, and the API does not require one.

Do I need a Searchland licence to use the API?

Green circular button with a white down arrow inside.

The same datasets that power the platform: planning applications & appeals, documents, ownership & title, constraints & policy, strategic land (SHLAA, allocations), energy & infrastructure, and sold-price comparables.

Can I integrate the data with my own GIS?

Green circular button with a white down arrow inside.

Bulk for large national datasets and internal databases. REST for real-time per-query access inside your software. GIS for spatial analysis directly in ArcGIS or QGIS alongside your own layers.

What owner types can I identify?

Green circular button with a white down arrow inside.

Yes, we have integrated Land Registry document purchasing into our API structure.

Can I see a sample before buying?

Green circular button with a white down arrow inside.

Yes. We can share a sample dataset or schema overview so your technical team can confirm the structure fits before integrating.
