What is prior approval?
Certain types of development are granted planning permission by national legislation without the need to submit a planning application. This is known as 'permitted development'. In order to be eligible for these permitted development rights, each 'class' specified in the legislation has associated limitations and conditions that proposals must comply with.
One such condition on certain classes of permitted development is the need to submit an application to the local planning authority for its 'prior approval; or to determine if it’s 'prior approval' will be required.
This allows the local planning authority to consider the proposals, their likely impacts in regard to certain specific factors (e.g. transport and highways) and how these may be mitigated.
For more information on prior approval, read guidance on prior approval consent types.
Common Questions
Planning permission is not required to remove an internal chimney breast as the change does not impact the exterior of the house. Rules may differ if you are planning on removing the chimney stack, or if you are in a conservation area.
If you live in a listed building, then you will need to apply for listed building consent for any major changes to the building.
Building regulations approval will always apply when removing chimney breasts as they are part of the building’s structure. You should seek advice from a structural engineer who will provide drawings and calculations that can be submitted as part of your application.
Planning permission is not required to move an internal doorway, provided it does not impact the external appearance of the building. If the building is listed, you will require listed building consent for any changes to the building.
Building regulations may apply if the wall is load bearing or is part of a fire escape route.

Whether raising the height of an external door requires planning permission depends on the location of the door, location of the property and how drastic the height change will be.
For smaller changes to the side and rear of the property, permitted development rights may apply, meaning no application or planning permission is required.
Where the height change will be substantial and have a significant impact on the building’s appearance, planning permission is likely to be required. Especially in cases where the door to be heightened is on the principal elevation of the property.
Principle elevation - The most visible or prominent side of a structure, typically facing a street or public area. While often considered the 'front' of the building, it may not always contain the main entrance.
In designated areas such as conservation areas, or on listed buildings you may require additional approvals such as listed building consent.
If you believe permitted development rights apply to a small change, you can apply for a lawful development certificate to ensure this is the case.
Building regulations
Building regulations approval will likely be required where the change impacts the structure of a building, this primarily occurs when an opening is widened. When altering walls you may want to consult a structural engineer.
A carport can fall under permitted development rights provided it meets certain limits and conditions set out in legislation. If you exceed or fail to meet a requirement then you will require planning permission.
If not attached to the house, a car port will be treated as an ‘outbuilding’. A full list of requirements is available on our outbuildings common project.
Adding an internal wall will not require planning permission or building control approval in most cases. If the building is listed, then you may require listed building consent to make a major alteration to the house.
Any work completed should adhere to building regulations, ensuring fire routes, electrics and ventilation are considered.
