What is Biodiversity Net Gain?

Biodiversity Net Gain (BNG) is an approach to development, and/or land management, that aims to leave the natural environment in a measurably better state than it was beforehand. It uses a metric based approach to predict the net change in biodiversity value that will occur as a result of development, or a change in land use. The requirement to deliver 10% BNG is mandated through the Environment Act (2021).

From 12th February 2024, all new planning applications for major development (subject to the specified exemptions) are required to deliver a minimum of 10% gain.

BNG for small sites has an extended transition period and BNG will apply from the 2nd April 2024.

What Is BNG

Biodiversity Net Gain in Kent and Medway

There is a commitment across the county to develop a shared and consistent approach to BNG. Kent’s LPAs (including the unitary authority of Medway) are jointly funding the development of guidance and resources to inform BNG delivery. This joined up approach is being supported and coordinated by Kent County Council (KCC), who are hosting the Kent Biodiversity Officer post.  As part of the ongoing programme of support a number of  resources have been produced, with additional guidance to be published when available.

BNG Guidance for Kent and Medway has been produced to support applicants and decision makers in implementing BNG. Some of this guidance sets out specific guidelines for implementation in Kent and Medway and other aspects summarise and signpost to the national guidance.
