Biodiversity Net Gain's Big Bang Moment

To The Point
(4 min read)

After some delay, the mandatory Biodiversity Net Gain regime has finally taken effect in England.  This briefing provides an overview of the new regime which will require most planning permissions granted in England to deliver at least a 10% net gain on the site's pre-development biodiversity value.  It considers what development is caught by mandatory BNG and sets out our thoughts on some of the unknowns, opportunities and challenges that are ahead. 


Our recent blogs on Biodiversity Net Gain (BNG) had been charting the Government's progress towards the implementation of the mandatory BNG regime for certain town and country planning applications in England, with our last blog on Biodiversity Net Gain (BNG) noting that the Government had pushed its proposed implementation date back to January 2024.

In the end, that revised implementation date was missed and the new regime finally took effect on 12 February 2024 for major planning applications.   It will take effect for non-major planning applications on 2 April 2024.

A different version of the BNG regime (tailored to the DCO process) will be implemented for Nationally Significant Infrastructure Projects (NSIPs) in November 2025.
