Planning obligations are legal agreements made between the borough council and developers. They are also known as Section 106 agreements.

They can be applied when we grant planning permission and often include obligations to offset the impacts of a proposed development. This requires the developer to pay for things such as providing community infrastructure and affordable housing.

Most agreements are site-specific and relate to the policies contained within our adopted development plan, in accordance with the tests set out in the National Planning Policy Framework 2019 and the Community Infrastructure Levy (CIL) Regulation 2010.

Our planning obligations protocol provides best practice guidance on managing Section 106 planning obligations. We also publish an infrastructure funding statement, which sets out the types of infrastructure and projects we intend to fund through Section 106 income over the next reporting period.
