What coverage means in practice

A useful planning dataset needs more than a council count. Buyers need to know whether records are recent, whether they include source links, whether dates are present, and whether the same API shape works across different councils.

Public coverage should help you judge reliability quickly. Paid plans expose council-level coverage and freshness metadata through the API, so teams can confirm the specific sources that matter to their workflow.
