Comparison
PlanWire vs UK Planning API: what developers should compare.
If you are choosing a planning API, compare query breadth, source traceability, freshness visibility, webhook support and how clearly each provider reports coverage.
Developers use PlanWire when they need live planning data without maintaining council-source integrations, with UPRN where available for property-dataset joins. Source-linked application records, freshness metadata and webhook workflows. Check current council-level coverage and history for your integration.
Developer test
The fastest comparison is to run the same use case through each API with your real councils and filters.

Use the same buying checklist for every provider.
A planning API is not just a record count. The hard questions are about coverage, freshness, data rights and product fit.
Coverage transparency
Can you see which live authorities are covered and which sources need attention?
Query model
Can your product filter by council, postcode, radius, dates, reference, status and keywords?
Source traceability
Can your users or team verify a record against the public source when needed?
Delivery model
Can you combine API polling with signed webhooks for operational workflows?
Compare documented behaviour
| UK Planning API | Its public docs cover application search, change feeds and webhooks, and distinguish production-ready councils from in-progress historical backfills. Check readiness for your own territory. |
|---|---|
| PlanWire | Normalised records with source links, separate source-check and data-freshness signals, signed webhook delivery and cursor-based captured-event recovery. Inspect coverage and sample responses before buying. |
| Evaluation | Use matching councils and date windows to compare fields, missing values, source evidence, event semantics, usage costs and licence terms. Do not treat a council count as a completeness guarantee. |

Questions buyers ask
How should I compare UK planning APIs?
Use your real query patterns, councils, date windows and webhook needs. Record count alone will not show operational fit.
Can I test PlanWire before paying?
Yes. A free key lets you inspect API shape and sample workflows before a paid plan.
Does PlanWire publish coverage status?
Yes. PlanWire has a public coverage page and API metadata for supported councils.
