BNG 2024: Latest Policy Updates & What They Mean for Developers

The introduction of mandatory Biodiversity Net Gain (BNG) requirements marks a significant change in how developments must interact with the natural environment. Under the Environment Act 2021, all new developments in England must achieve at least a 10% biodiversity net gain starting in 2024. These updates have far-reaching implications for developers, planners, and landowners.

This blog outlines the latest BNG policy updates, key deadlines, and what these changes mean for your development projects.

What’s New in BNG Policy for 2024?

BNG policy updates include the following key changes:

1. Mandatory BNG for Major Developments

   • From January 2024, major developments must demonstrate at least a 10% biodiversity net gain as part of their planning applications.

2. BNG for Smaller Sites

   • From April 2024, BNG requirements extend to smaller developments. This includes single-home builds and other minor projects.

3. Use of the Biodiversity Metric 4.0

   • Developers must use the latest Biodiversity Metric, developed by Natural England, to calculate baseline habitat values and improvements.

4. Nationally Significant Infrastructure Projects (NSIPs)

   • From 2025, BNG will apply to large infrastructure projects, such as road and rail developments.

5. Statutory Biodiversity Credits

   • Developers can purchase government-regulated biodiversity credits if on-site and off-site solutions are not feasible. However, this should be a last resort.

     
     

Why Do These Changes Matter?

The new policies ensure that developments contribute positively to the environment rather than causing harm. For developers, this means:

• Increased Planning Scrutiny: Projects must demonstrate clear biodiversity enhancements to gain approval.

• More Strategic Planning: Early-stage ecological surveys and habitat planning are now essential.

• Cost Implications: On-site habitat creation and purchasing BNG credits could impact project budgets.

  
  

Key Deadlines for Developers

Date	Requirement
January 2024	BNG mandatory for major developments
April 2024	BNG applies to smaller developments
2025	BNG extended to Nationally Significant Infrastructure Projects (NSIPs)

How to Prepare for BNG Compliance

To meet the new requirements, developers should:

1. Commission Early Ecological Surveys

   • A Preliminary Ecological Appraisal (PEA) should be undertaken at the start of the project to establish baseline conditions.

2. Understand the Biodiversity Metric

   • Work with ecologists to calculate biodiversity losses and gains using the Sta.

3. Plan for On-Site Biodiversity Enhancements

   • Consider options such as:

     • Creating wildflower meadows.

     • Planting native hedgerows.

     • Enhancing existing habitats.

4. Explore Off-Site Solutions

   • If on-site enhancements are limited, identify local habitat banks or landowners offering BNG credits.

5. Engage Early with Local Planning Authorities (LPAs)

   • Ensure your Biodiversity Gain Plan (BGP) meets local requirements and policies.

     
     

Challenges Developers May Face

1. Increased Costs

   • Habitat creation, long-term maintenance, and purchasing credits may add financial strain to projects.

2. Complex Calculations

   • Using the Biodiversity Metric can be challenging without expert guidance.

3. Time Constraints

   • BNG planning and approvals can delay project timelines if not addressed early.
