Biodiversity Net Gain

Last Modified March 14, 2024

From the 12th February 2024, local planning authorities were required to implement Biodiversity Net Gain as part of their planning requirements for developments.

BNG is an approach to development. It makes sure that habitats for wildlife are left in a measurably better state than they were before the development.

In England, BNG is mandatory under Schedule 7A of the Town and Country Planning Act 1990 (as inserted by Schedule 14 of the Environment Act 2021).

Developers must deliver a BNG of 10%. This means a development will result in more or better quality natural habitat than there was before development. 

The Biodiversity Net Gain Supplementary Planning Document ensures that a development provides an increase in biodiversity post development compared to before the development started, and outlines Hertsmere's expectations regarding Biodiversity Net Gain.
