Biodiversity Net Gain Suffolk: Understanding BNG
As of February 2024, mandatory BNG (Biodiversity Net Gain) is a key requirement for most new planning applications across England. Under the Environment Act 2021, all qualifying developments – whether urban or rural – must leave the natural environment in a measurably better state than it was pre-development. In Suffolk, Biodiversity Net Gain (BNG) is now a central part of the planning process and is being enforce through national legislation and local planning authority policy.
BNG and Local Policy in Suffolk
The planning authorities in Suffolk, under Suffolk County Council instruction, requires that all developments demonstrate at least a 10% net gain in biodiversity. This must be evidenced through a compliant biodiversity net gain plan, which clearly outlines how the proposal will conserve or enhance habitats and priority species both during and post development.
Developers are also encouraged to align with Suffolk’s Local Nature Recovery Strategy (LNRS) to promote ecosystem restoration and long-term environmental resilience.
Meeting BNG Requirements in Suffolk
Biodiversity Net Gain applies to both major and minor developments, including:
- Residential developments of 10+ homes or sites over 0.5 hectares
- Smaller developments with fewer than 10 dwellings or under 1,000m² non-residential floorspace
Regardless of size, all planning permissions must demonstrate how biodiversity will be enhanced using the biodiversity metric, such as the Statutory Biodiversity Metric tool. Where on-site enhancements aren’t feasible, purchasing approved biodiversity units becomes essential.
Key Principles of Biodiversity Net Gain
To effectively deliver BNG Suffolk, developers should follow these ten best practices:
- Avoid biodiversity loss using the mitigation hierarchy
- Protect irreplaceable and high – value habitats
- Engage transparently with stakeholders
- Prioritise long-term environmental sustainability
- Collaborate with ecologists and local experts
- Deliver meaningful, measurable improvements to biodiversity
- Mitigate risks to ensure durable outcomes
- Consider exceeding the 10% minimum net gain
- Use reliable assessment tools like the latest biodiversity metric
- Focus on real, lasting benefits for nature and local communities
