FAQ
Answers.
Where does the EPC data come from?
We collect and clean Energy Performance Certificate data from open data communities, covering residential properties across the UK going back to 1990.
How often is the EPC data updated?
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?
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?
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 does each record include?
Yes, we have integrated Land Registry document purchasing into our API structure.
Can I see a sample before buying?
Yes. We can share a sample dataset or schema overview so your technical team can confirm the structure fits before integrating.
