Section 106 planning obligations

About the Community Infrastructure Levy (CIL) and how it's being introduced by councils in Suffolk and information on the Section 106 Developers Guide.

Suffolk's public service providers have worked together to produce guidance on the countywide approach to developer contributions.

Community Infrastructure Levy (CIL)

A Community Infrastructure Levy is a standard charge on developments that will replace some of the obligations currently created under Section 106 agreements. 

The CIL is governed by The Community Infrastructure Levy Regulations 2010 (as amended). The most recent amendments to the CIL Regulations were in 2019

Most of Suffolk's local planning authorities are aiming to introduce a CIL charging schedule as stated below:

A section 106 agreement is a private agreement made between the local planning authority and developers or landowners setting out:

  • the nature of the development (the amount of affordable housing that must be built)
  • a payment from the developer to provide proportionate additional infrastructure
  • contributions to compensate for loss or damage created by development (such as a loss of open space)

All planning authorities, including the county, district and borough councils, have worked together to produce a countywide guide to Section 106 Agreements. It is not definitive but it will give you an idea of what obligations to expect.

The government sets out how it expects planning obligations, including section 106 agreements, to be used in the following statutory guidance:

Further information on the guide

The Code of Practice Protocol (PDF, 120KB) is an agreed approach that explains how local planning authorities and service providers will assess developer contributions. 

Borough or district councils are responsible for most planning decisions.
