Prior Approval Vs Planning Permission
Prior approval sits in the middle ground between a simple permitted development assumption and a full planning application.
That overlap is why people often hear that permission is not needed and then discover that some form of application is still required.
Short Answer, Main Qualifiers, Best Next Step
Short answer
Prior approval sits in the middle ground between a simple permitted development assumption and a full planning application.
What could change it
- Prior approval is not the same thing as full planning permission, even though the council still has to assess specified issues.
- The route depends on the exact type of development and the legal framework that applies to it.
- Using the wrong route wastes time because the evidence, expectations and risks are not identical.

Open pageWhy People Mix The Two Up
Prior approval sits in the middle ground between a simple permitted development assumption and a full planning application. The development may benefit from a legal route that avoids full planning permission, but the council may still need to approve specific matters before work starts.
That overlap is why people often hear that permission is not needed and then discover that some form of application is still required.
Why The Distinction Matters Early
The practical difference matters because the route affects what you need to prepare, how the council will assess the proposal and which issues can become the deciding factors.
A project on the prior approval route should not automatically be treated as either risk-free or equivalent to a full planning application. It has its own logic and its own evidence needs.
- Do not assume prior approval is just a faster version of planning permission.
- Do not assume a prior approval route exists until the exact project type has been checked.
- Good route choice at the start reduces wasted drawing and application work later.
Questions People Usually Ask Next
Does prior approval mean I do not need to involve the council?
No. Prior approval exists precisely because the council still needs to assess specified matters before work proceeds.
Is prior approval always easier than planning permission?
Not always. It can be more limited in scope, but the route still needs to be satisfied carefully and the wrong assumptions can cause delay.
What should I do if I am not sure which route applies?
Treat the route question as the first decision, then use the matching guide or tool before commissioning the wrong evidence package.
Need A More Case-Specific Steer?
If this FAQ answers the broad process question but your own case still turns on the details of the project, the property or the local authority area, use the structured guidance form for a more tailored case-specific steer.
Best for
Borderline, awkward or site-specific cases where broad guidance has helped, but the answer still turns on facts that are unique to your property or proposal.
What the reply aims to do
The reply aims to narrow the likely route, flag the tripwires that matter most, and tell you which verification step is safest before more money is spent.
What to include
Property type, council area, location, the change you want to make, approximate dimensions, relevant heritage or flat-related details, previous additions and the main concern.
Important: Replies are informational personalised guidance based on the details you provide and publicly available information. They are not formal legal, architectural, surveying or council advice. Site-specific or borderline cases may still need checking with the local authority or a qualified specialist before drawings, applications or contractor spend move ahead.

- Using the wrong route wastes time because the evidence, expectations and risks are not identical.
When to stop reading and verify
Stop relying on the FAQ alone when the answer now depends on one address, one exact drawing, one local control or a decision that would be expensive to get wrong.
