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.
