Developer Contributions

Planning plays a fundamental role in helping to ensure that the impacts of development are appropriately mitigated and that the right infrastructure is in place to support it.

Developer contributions is a collective term mainly used to refer to the Community Infrastructure Levy (CIL) and Planning Obligations (commonly referred to as ‘Section 106’ or ‘S106’ obligations after Section 106 of the Planning Act). These are planning tools that can be used to secure financial and non-financial contributions (including affordable housing), or other works, to provide infrastructure to support development and mitigate the impact of development.

Developer contributions should be used appropriately and effectively and to to achieve this they should be considered throughout the planning cycle. Here we share some resources with you to help in that consideration.


Local authorities have a fundamental role in leading the coordination and delivery of infrastructure that will support their areas. Effective infrastructure planning, prioritisation and governance of spend are critical to supporting the delivery of sustainable development and growth. To help your senior leadership understand the role of developer contributions we have published an advice note on the role of CIL and S106 including policies and processes. It has been developed in response to recent changes in legislation and Planning Practice Guidance (PPG) on how they can be used effectively and how they must be reported on.

This advice note provides a series of factsheets that contain information and advice on how to develop and improve your approach to developer contributions. It raises key questions for you and your leadership teams that will help you 'health check' your CIL and S106 systems and resources.
