Planning permission is not a party wall notice. The planning system assesses matters such as whether development is permitted under planning law. The Party Wall etc. Act regulates certain work affecting shared structures, boundaries and neighbouring foundations in England and Wales.
If I have planning permission, do I still need notice?
Possibly. GOV.UK states that getting planning permission or complying with building regulations does not remove the need to comply with the Party Wall Act where it applies. You may need notice even when the plans have already been approved.
What about permitted development?
Some projects do not need a full planning application, but they may still involve notifiable boundary, shared-wall or excavation work. There is no exemption simply because the extension falls within permitted-development rules.
Does party wall consent mean planning approval?
No. The neighbour's response to a party wall notice does not grant planning permission or prove building-regulation compliance. These systems answer different questions.
Which should you check first?
Early in design, discuss both planning status and any party wall implications with your architect or builder. Obtaining foundation and structural information early avoids delays when drafting accurate notices.
