Planning obligations under Section 106 of the Town and Country Planning Act 1990 (as amended), commonly known as s106 agreements, are a mechanism which make a development proposal acceptable in planning terms, that would not otherwise be acceptable. They are focused on site specific mitigation of the impact of development. S106 agreements are often referred to as 'developer contributions' along with highway contributions and the Community Infrastructure Levy.
Planning obligations are legal obligations entered into to mitigate the impacts of a development proposal. This can be via a planning agreement entered into under section 106 of the Town and Country Planning Act 1990 by a person with an interest in the land and the local planning authority; or via a unilateral undertaking entered into by a person with an interest in the land without the local planning authority. Planning obligations run with the land, are legally binding and enforceable. A unilateral undertaking cannot bind the local planning authority because they are not party to it. Planning obligations are also commonly referred to as ‘section 106’, ‘s106’, as well as ‘developer contributions’ when considered alongside highways contributions and the Community Infrastructure Levy. The National Planning Policy Framework requires all local planning authorities and certain other organisations to publish their developer contributions data on a regular basis and in an agreed .csv format. Alls planning obligation agreements can be found on the planning register under the application reference number. Applications can be searched on the Find a Planning Application page.
