You should use this page if:
You are unsure whether you need planning permission for works you are carrying out
Building works have already been carried out and you would like to find out whether planning permission or building regulation consent should have been in place.
In these cases, please use the Planning Portal (external link) as your first port of call. There is a very useful tool called the interactive house that gives details on common household projects.
If you still need help after looking at the Planning Portal, please complete the relevant form on the right and return it to us so we can advise you further.
These forms can also be used if you would like to find out whether building regulation approval is needed.
