Do you need planning permission for your project?

Drop in a postcode. We cross-reference live council and Historic England datasets — conservation areas, flood zones, listed buildings, Article 4 directions, tree preservation orders — and give you a plain-English verdict on whether planning permission is likely to be required.

Site location

Where is the project?

Enter the postcode for the property or site you wish to screen. We use it to resolve the correct local planning authority and pull constraint layers covering that exact polygon.

Indicative, not advisory. Our screen is built on authoritative live datasets — but not a substitute for RTPI-accredited consultancy on borderline schemes.
Postcode resolves to a polygon. If your site straddles two authorities or sits within a defined block, we'll flag it on the next screen.

Fifteen constraint categories

What we check

Every screen runs the full panel — there are no upsells gated behind specific layers.

Conservation Area
Listed Building
Article 4 Direction
Flood Zone 2 / 3
Tree Preservation Order
Permitted dev. limits
Local plan policies
Recent application history

All fifteen run on every postcode, free.

How the screen works

Three steps from postcode to verdict.

The same workflow a planning consultant would run manually — automated, structured, and grounded in citable sources.

01 — Resolve

Site polygon & LPA

Your postcode is matched to a Royal Mail polygon, then routed to the correct local planning authority. Cross-boundary sites are flagged so you don't get a partial picture.

02 — Screen

Fifteen live datasets

We query authoritative national registers in parallel — Historic England, Environment Agency flood maps, Natural England designations, planning.data.gov.uk, and recent application history.

03 — Report

Plain-English verdict

Every constraint comes with a short explanation, the policy reference behind it, and what it typically means for a homeowner project at that location.
