The UK Government has opened a consultation on the implementation of Biodiversity Net Gain (BNG), inviting feedback particularly in relation to minor, medium, and brownfield developments. This marks an important opportunity for professionals working in planning, housing, and environmental sectors to contribute to shaping a policy that affects every stage of the development process.
BNG is designed to ensure that development projects leave biodiversity in a better state than before. It is a principle that aligns with our commitment to sustainable development. However, current challenges in implementation are putting significant pressure on small-scale development.
Smaller developments are often disproportionately impacted by the cost and complexity of meeting BNG requirements. These additional demands can undermine the financial viability of projects, placing particular strain on smaller housebuilders who are already working within tight margins.
Brownfield and mosaic habitats are frequently penalised by the current biodiversity metrics, despite their key role in the national strategy for regeneration and housing delivery. This misalignment risks discouraging the reuse of land that is essential to sustainable growth. At the same time, we are witnessing a surge in self-build applications, which are currently exempt from BNG.
We believe that Biodiversity Net Gain can and should be part of a sustainable development future. But if it is to succeed, the system must be flexible, proportionate, and practical for all types of projects—large and small.
The government’s consultation seeks views on several potential improvements, including revisiting the scope of exemptions, simplifying requirements for small sites, improving access to off-site BNG options, and addressing specific challenges related to brownfield development.
This is a timely and important chance for stakeholders across the sector to shape the future of BNG implementation. If you work in planning, housing, or environmental sectors, we encourage you to share your experiences and insights.
Let’s make sure the system supports both nature recovery and sustainable growth.
