What is CIL and Section 106?

Community Infrastructure Levy (CIL) 

CIL is a levy local authorities in England and Wales can charge on developments in their areas.

This income can then be used to fund infrastructure required to support those new developments.

Within the South Downs National Park you may need to pay the levy if you are undertaking a development which creates new residential or large format retail floor space.

Residential development includes extensions, annexes and holiday lets.

Section 106 

CIL aims to replace developer’s contributions (also known as planning obligations) secured via Section 106 (S106) Legal Agreements.

However, S106 legal agreements are still required to secure affordable housing and site specific measures required to make a development acceptable.

Parts of the South Downs National Park are also within the Solent Recreation Mitigation Strategy 5.6km zone.

Therefore, developer contributions, secured via a S106 legal agreement, will be required to mitigate the impacts of developments within this area.

Funding grants from S106 contributions are currently still available from the SDNPA, further information on how to apply for S106 grant funding is available below.
