Section 106: Planning obligations

Find out about planning obligations and how developer contributions are calculated.

1 Overview

Please be aware that from 1 April 2020 we will introduce a S106 monitoring fee to mitigate against the administrative work involved in monitoring the legal obligations contained in Section 106 Agreements.

Planning obligations address the issue of how facilities and services adversely affected by a particular development can be protected, enhanced, maintained or, where appropriate, new provision made. For example, where there is a new development there may be a need to improve education and social care facilities.

Contributions towards the provision of these facilities are secured in a Section 106 agreement.

Requirements for planning obligations are set out in:

3 Services requiring contributions

Contributions may be required for:

  • highways 
  • education and other facilities for children and young people
  • fire and rescue services, including fire hydrants
  • libraries
  • services supporting older people and those with disabilities and mental health needs
  • waste management.

The need for additional services is assessed by calculating the population increase likely to come from a proposed development.

Further information is in the document below:

To give you an idea of how much you may be liable to pay, use the calculator for the relevant district or borough in the documents below.

If unsure, check by entering the development site’s postcode on the district and borough council page.

To find out how contributions are calculated, read the 'Explaining contribution calculations' guidance.

5 Community Infrastructure Levy

The Community Infrastructure Levy is a levy that local authorities can choose to charge on new developments in their area. Once in force it will replace planning obligations, although some site specific obligations are likely to remain.

Money raised from the levy can be used to support development by funding infrastructure that the council, local community and neighbourhoods want. This could be new or safer road schemes, park improvements or a new health centre.

Each district and borough council in West Sussex will decide whether to implement the levy in their area. For further information contact the appropriate district or borough council.
