Developers use PlanWire when they need live planning data without maintaining council-source integrations, with UPRN where available for property-dataset joins. 18.3M+ planning application records, 375 live planning authorities, source links, freshness metadata and webhook-ready workflows.
Example postcode query
Start with a postcode and radius, then narrow by date, status, keyword or council when needed.
GET /v1/applications?postcode=SW1A%201AA&radius_km=2&date_from=2026-09-01
Built for location-led planning workflows.
A postcode query should return usable records, not a pile of local source differences for your team to reconcile.
Radius search
Search near addresses, sites, branches, assets and customer territories using postcode or coordinate inputs.
Saved areas
Use the same filters behind Watch this area emails, property dashboards and internal monitoring views.
Record context
Return references, dates, descriptions, council IDs, source URLs, UPRN where available and location fields in a consistent shape.
Freshness checks
Pair postcode results with coverage and source freshness metadata so users know how current the area view is.
