Ecology Planning Projects
What is Biodiversity Net Gain?
Nature is infrastructure. When development leaves habitats richer than it found them, communities stay resilient, planning consents run smoother and assets hold long-term value. Biodiversity Net Gain is the policy mechanism that makes that measurable and mandatory.
​
Biodiversity net gain (BNG) became an applicable part of planning law in February 2024 and in principle mandates that most planning applications in England must now demonstrate at least a 10% uplift in biodiversity value compared with the pre-development baseline.
That uplift (net gain) must be secured for a minimum of 30 years through retaining, where possible, existing ecological value and improving upon it through on-site design, off-site habitat creation or the purchase of statutory biodiversity credits.
