Planning permission in Wigan isn't a yes or no question — it's a question about your property, on your street, in your part of the borough. What's allowed for your neighbour might not be allowed for you, and most homeowners only discover that after they've already started. WhatCanIBuild exists precisely because the generic answer is almost never the right one.
The short version
- Whether you need planning permission depends on your specific property, not just the type of project
- Wigan has extensive Green Belt, multiple conservation areas, and local designations that can override standard rules
- The householder application fee is £258, and decisions typically take 8 weeks — but that assumes you get the application right first time
Wigan isn't one place — it's dozens of different planning environments
Wigan Metropolitan Borough covers a wide area, from WN1 through to WN7 and M29. Within that, you've got dense town centre streets, former mining villages, canal-side properties, and large stretches of Green Belt. Conservation areas include Wigan town centre, Standish, and several of those former mining villages. The Leeds and Liverpool Canal corridor carries its own heritage significance.
Each of these contexts comes with its own set of rules — and they don't always behave the way you'd expect. A straightforward rear extension in one part of the borough can trigger a full planning application just a few streets away. Most homeowners don't realise this until it's too late.
The things that trip people up most
Conservation areas. Article 4 directions. Listed building status. Flood zones. Green Belt designations. These aren't rare edge cases — they affect a significant number of properties across Wigan, and each one can change what you're allowed to do without permission.
Here's the problem: knowing you're in a conservation area is one thing. Understanding what that actually means for your specific project — a loft conversion, a side extension, a new outbuilding — is something else entirely. The rules interact with each other in ways that aren't obvious, and the combination of constraints on your property might be completely different from anything a general guide can cover.
Don't assume permitted development covers you
Permitted development rights can be removed from individual properties, entire streets, or whole areas through Article 4 directions. There's no easy way to know this applies to you without checking your specific address.
What's actually been approved nearby?
This is where it gets interesting. Even if you know your constraints, you still don't know how Wigan Council has been interpreting them in practice. What projects have been approved on your street? What's been refused, and why? Have similar extensions gone through without issue, or has the council pushed back on something that looked straightforward on paper?
That local decision history is arguably more useful than any rulebook — and it's the kind of thing WhatCanIBuild surfaces for your specific property, not just your postcode.
What this means for your project
If you're planning anything — an extension, a loft conversion, a new outbuilding, a driveway — the worst position to be in is confident you don't need permission when you actually do. Enforcement action, delays, and having to undo completed work are all real outcomes for homeowners who got it wrong.
The best way to know where you stand is to check your actual address against real planning data. WhatCanIBuild shows you what constraints apply to your property, what's been approved and refused nearby, and what that combination means for your specific project — not a property like yours, yours.
These rules vary by property
Conservation areas, Article 4 directions, and other constraints can change everything. Check what actually applies to your address.
