Biodiversity Net Gain (BNG) is now a mandatory planning requirement for most new developments in England. Developers must demonstrate a minimum 10% biodiversity net gain, secured and maintained for at least 30 years, as part of the planning process.
SynergiseUK connects developers, landowners, and investors with Specialist BNG Advisers who support compliance, strategy, and delivery, helping projects progress without unnecessary delay or risk.
BNG Advisory Disclaimer
SynergiseUK is not a planning authority or ecological consultancy. We introduce clients to independent, specialist BNG advisers, including ecologists and planning specialists. All advice, assessments, and calculations are subject to planning policy, local authority requirements, statutory guidance, and professional due diligence.
What Is Biodiversity Net Gain (BNG)?
Biodiversity Net Gain is a planning requirement that ensures development leaves biodiversity in a measurably better state than before. From 2024 onwards, most developments must evidence a minimum 10% uplift in biodiversity value.
BNG applies to:
-
Residential developments
-
Commercial schemes
-
Mixed use projects
-
Land led and phased developments
Compliance must be demonstrated using approved biodiversity metrics and secured through legal and planning mechanisms.
What Does BNG Mean for Developers?
BNG is not optional. Failure to address it early can result in:
-
Planning delays
-
Refused applications
-
Cost escalation
-
Reduced scheme viability
Early advisory input allows developers to integrate BNG efficiently into scheme design, land strategy, and financial modelling.
How BNG Can Be Delivered
BNG can typically be achieved through one or a combination of the following routes:
On Site Biodiversity Gains
Incorporating habitat creation or enhancement within the development boundary.
Off Site Biodiversity Units
Securing biodiversity units on alternative land where on-site delivery is not viable.
Statutory Biodiversity Credits
Used as a last resort where on site and off site options are not feasible.
Specialist advisers assess the most commercially and operationally appropriate route for each scheme.
When BNG Applies
BNG requirements generally apply where:
-
A planning application is required
-
Development impacts existing habitats
-
The site is not exempt under transitional rules
BNG must be evidenced at planning stage and legally secured prior to commencement.
