Building works which are not exempted from Planning Regulations are called ‘unauthorised developments’, and they require a retention planning application to be lodged with the local authority.

What Is the Difference Between Planning Permission and Retention Planning Permission?
Planning Permission
Planning permission is permission for a structure you intend to build.
Retention Planning Permission
Retention permission is permission for an unauthorised structure, or a partially constructed structure, that has already been built without planning permission. This is very risky, but retention permission is there to try to regularise the matter with the local authority. The process and procedure are exactly the same for both planning permission and retention permission.
What Happens If Retention Permission Is Refused?
If a genuine mistake has been made, it is possible to apply for retention planning permission to retain the unauthorised development. This permission may be refused, in which case the unauthorised development will have to be demolished.
Common Reasons You May Need Retention Planning Permission
The most common reasons our clients need retention planning permission include:
Extensions to the Side or Front of Your House
Extensions built to the side and/or front of the existing house are not exempted development and will require retention permission if built without planning permission.
Rear Extensions Over 40 Square Metres
Extensions built to the rear that exceed the permitted 40 sq. metres will also need retention permission, along with other specialised cases.
Vehicular Access and Boundary Walls
Most clients are unaware that you need retention planning permission if you extend your vehicular access or increase the height of your boundaries. Check with your local authority for the exempted heights.
How Long Does a Retention Planning Application Take?
Generally, the local planning authority must make an initial decision on a planning application within 8 weeks of receiving the application, with a further 4 weeks for a final decision or Final Grant of permission. The process may take longer if the authority needs further information, or if any appeals are lodged.
The process and procedures are exactly the same as for an ordinary planning permission.
