Local Authority Finder

Find out which council decides planning applications for your home. Enter your postcode — or just the first part of it — and we'll tell you.

We don't store your postcode — it's used for this lookup only. Enter just the first part (e.g. SK8) if you'd rather not give the full thing.

Good to know

Why does it matter which council I'm under?

Your local planning authority decides your application, sets local policy on things like conservation areas and Article 4 directions, and has its own validation checklist. Two houses a mile apart can sit under different councils with different expectations.

Is my council the same as my county?

Not always. In Greater Manchester, for example, planning is handled by the individual borough — Trafford, Stockport, Wigan and so on — not by a Greater Manchester body. This tool gives you the council that actually determines applications.

Does this tell me whether I need planning permission?

No — it tells you who you'd apply to. Use our Planning Checker for a quick read on whether your project is likely to be permitted development, and we'll confirm properly on a free call.

Not sure whether to build, wait or move?

That's exactly what the call is for. We'll be straight with you — no pressure, no jargon, no nasty surprises.
