For architects
Check before you submit.
For applications dated on or after 1 April 2026, the Planning Inspectorate's new procedural guide means that in most cases no new evidence can be accepted at appeal. The application you submit carries the whole argument. A quick check of the record now is cheaper than an awkward client conversation later.
From £29/month. No sales call, no credit card.

How you'd use it
Each appeal decision is a ruling on which arguments held up, which policies carried weight, and why. Right first time now depends on what you know before you submit. Three places that matter:
FORM AN EARLY VIEW
See the big picture.
Checking local applications is a good place to start. The appeal record adds the national picture: how the same policies read when tested, in this authority and everywhere else. More consistent, more defensible ground for your advice.
AT DESIGN STAGE
Design the approach.
Check how policies perform at local and national level before the design settles, and take the risk out early. Search 1.1M policy citations to see how a policy is read, and put decided cases behind your advice.
CHECK EACH POINT
Quality information, fast.
Each argument checkable against the inspector's words, each row traceable to its decision letter. Open the original documents, and the linked planning application, and check for yourself.
Checking takes minutes. The time goes back into the design.
What you get, and what you don't.
We're not planning consultants. We don't write your statement, weigh your case, or give advice. We put the evidence in front of you: the cases, the inspector's reasoning, and patterns across the whole record that no manual search would surface. You draw the conclusions. The report is yours.
