Planning Compliance


Planning Compliance

Compliance is a planning service offered to those who suspect alleged breaches of planning control are taking place.  In order for a thorough investigation to commence, we require a written complaint using our online form or a letter sent to the Compliance team to the address as set out at the bottom of this page.

This complaint should include the site address, nature of complaint and any supporting materials such as photographs. Please note that anonymous complaints are not investigated.

When investigating a complaint, we may ask you to fill in a Diary of Events Form [doc] 34KB. To record the activities which you believe are breaches of planning for a 21 day period. This will enable the Compliance Team to decide what action is appropriate.


What constitutes a breach of planning control?

  • Carrying out of development without the necessary planning permission
  • Non-compliance with conditions resulting from planning permission
  • Works to a Listed Building without the relevant Listed Building Consent and/or planning permission - Listed Building information
  • Works to a tree with a Tree Preservation Order or tree within a Conservation Area Further information can be found on the Tree Preservation Orders page. 
  • Displaying a sign or advertisement without relevant Advertisement Consent.  Please check with a member of the Compliance Team for specific details relating to this legislation.
  • Unauthorised demolition of certain buildings within a Conservation Area.
  • Land or buildings in such poor condition that it adversely affects the amenity of the area.

  • Boundary disputes. These are a civil matter and must be pursued privately. Please also refer to the  Party Wall Explanation Booklet [pdf] 3MB
