What is Biodiversity Net Gain (BNG): BNG in Brent (London)?
Biodiversity Net Gain (BNG) refers to the requirement that new development must leave biodiversity in a measurably better state than before. In the context of BNG in Brent, this means your site must provide a positive biodiversity uplift, in line with the Environment Act 2021 and national policy. According to the draft Sustainable Environment & Development SPD for the London Borough of Brent, a minimum 10 % biodiversity net gain is expected on most new developments.
Delivering BNG in Brent therefore means quantifying baseline habitat value on-site, designing new or enhanced habitats, and producing robust documentation to satisfy both the local planning authority and national validation requirements. Effective BNG in Brent requires technical accuracy, planning awareness and sustainable outcome measurement.
In practical terms, this means biodiversity must be considered as part of the core design process rather than addressed later in the planning stage. In Brent, where development often involves constrained urban sites, regeneration areas and limited green space, achieving the required uplift requires a carefully planned and evidence-based approach. This may include the integration of green roofs, urban planting, sustainable drainage features and habitat connectivity measures within the scheme layout.
The Statutory Biodiversity Metric is used to calculate both baseline and post-development biodiversity value in measurable units. This relies on accurate habitat surveys, condition assessments and clearly defined enhancement proposals. In Brent, poorly evidenced or inconsistent submissions can lead to validation delays or requests for further ecological information, particularly where proposals do not clearly demonstrate how the required net gain will be delivered.
Brent Council may also expect developments to contribute to wider ecological networks, urban greening objectives and local biodiversity priorities where relevant. Aligning proposals with these wider objectives can help strengthen planning applications and support long-term environmental performance.
Environment Act 2021 and Local BNG Policy: BNG in Brent (London)
The Environment Act 2021 introduced mandatory biodiversity net gain in England. Under that legislation, almost all new developments must demonstrate a net gain of biodiversity at least 10 % as a condition of planning consent.
In Brent, the validation list for planning applications states that “Biodiversity Net Gain information including the BNG Metric” must be submitted from February 2024 for major applications, and from April 2024 for nearly all applications, subject to exemptions.
Further, Brent’s local planning documents recognise a commitment to nature and green infrastructure, insisting on stronger biodiversity outcomes. For example, the Brent Tree Strategy cites that Local Plan Policy BGI1 sets out a mandatory 10 % increase in biodiversity for most developments.
What this means is that for your project delivering BNG in Brent you must:
- Use the approved habitat metric (e.g. the Defra Biodiversity Metric 4.0) for baseline and post-development calculation.
- Provide supporting documentation, such as a Biodiversity Gain Plan, Habitat Monitoring and Management Plan, and Statement of Conformity, often secured via Section 106 agreement.
By understanding the local authority’s expectations and the national requirement your scheme can proceed with confidence and avoid delays or invalidation of planning submissions.
Using DEFRA’s Statutory Biodiversity Metric 4.0
A key component of delivering BNG in Brent is the correct use of the Defra Biodiversity Metric 4.0 (or later version) to calculate the pre- and post-development biodiversity units.
The process begins with a baseline habitat survey our specialist ecologists record habitat types, condition, distinctiveness and other parameters. Then the post-development scenario is modelled, including habitat creation, enhancement or retention proposals. The difference is the net gain or loss, expressed in units.
For developments in Brent, the planning submission must include a metric calculation, with the version and publication date specified.
If the onsite calculation shows less than a 10 % uplift, additional measures are required. These might include off-site biodiversity credits or habitat banking.
- Early-stage baseline BNG surveys and desk review of local constraints (protected species, SINC, greenbelt)
- Full BNG metric assessments, enhancement design, risk evaluation and management planning
- Development of BNG action plans, habitat monitoring and management plans to satisfy ongoing obligations
- Preparation of BNG exemption statements where applicable, and support for Section 106 or legal agreements
In Barnet, our BNG assessment in Barnet will incorporate Metric 4.0 calculations, check assumptions on habitat condition, ensure multipliers are applied properly and confirm that the uplift is documented to meet the minimum 10 % net gain threshold. Where on-site gain is constrained, our consultants in Barnet can advise on off-site habitat provision or credit purchase while aligning with Barnet Council’s validation checklist.

Frequently Asked Questions
Biodiversity Net Gain (BNG) in Brent is a statutory planning requirement for most development proposals, requiring developments to demonstrate at least a 10% measurable increase in biodiversity value compared to pre-development conditions. Introduced under the Environment Act 2021, BNG must be calculated using the Defra Biodiversity Metric and secured for a minimum 30-year period through planning conditions or legal agreements. In Brent, BNG is assessed alongside local planning policies, urban greening priorities and site-specific ecological constraints, making early ecological surveys and robust biodiversity net gain assessments essential to avoid validation issues and delays at planning determination stage.
What developments in Brent require a Biodiversity Net Gain (BNG) in Brent?
Most new developments in Brent must submit biodiversity net gain information including the metric. As the validation list states: “Biodiversity Net Gain information including the BNG Metric” is required from February 2024 for major applications and from April 2024 for all others (unless exempt).
Exemptions include certain very small sites or those not affecting habitats, but you should always check with Brent Council.
How much net gain is required for BNG in Brent?
Brent Council’s policy requires a minimum 10 % biodiversity net gain uplift for most new development sites.
If your on-site calculation cannot provide that uplift, you may need to use off-site measures or habitat banking to secure compliance.
What documents does Brent Council expect for BNG submissions?
For BNG in Brent, you should submit:
- A completed biodiversity metric calculation (showing version and publication date)
- A plan showing existing onsite habitat and proposed changes.
- Supporting narrative (e.g., Habitat Monitoring & Management Plan, Biodiversity Gain Plan).
Brent’s Supplementary Planning Document emphasises the need for legally binding obligations (such as via Section 106) where necessary.
Can I deliver BNG off-site for a Brent development?
Yes, if you cannot achieve the required uplift onsite, you can procure off-site biodiversity units or habitat banking to compensate. National guidance and schemes (such as those offered by The Wildlife Trusts) support this approach.
However, you must ensure the off-site option is acceptable to Brent Council and aligns with local biodiversity strategy.
How quickly can ACP Consultants deliver a BNG survey or assessment in Brent?
At ACP Consultants we aim for rapid turnaround while maintaining technical rigour: many standard BNG surveys / assessments can be delivered in as fast as one week depending on site complexity and access. Our reputation is built on transparency, reliability, understanding of local authority processes and technical excellence.
BNG in Brent map where does Biodiversity Net Gain apply?
BNG applies borough-wide in Brent, but sites near Sites of Importance for Nature Conservation (SINCs) and areas identified in London’s Local Nature Recovery Strategy often carry higher strategic significance in the metric. Use local datasets (e.g., GiGL) and GLA guidance to understand habitat opportunities before design. This improves outcomes for biodiversity net gain Brent projects and smooths validation.
BNG in Brent eligibility which applications are in scope or exempt?
Under national rules, most planning permissions must deliver at least 10% biodiversity net gain; some developments are exempt (for example, certain very small schemes). Brent’s validation notes require BNG information (including the metric) for majors from 12 Feb 2024 and for most minors from 2 Apr 2024, mirroring national commencement dates. Always confirm exemptions early to avoid invalidation.
BNG in Brent 2021 what changed with the Environment Act 2021?
The Environment Act 2021 amended the Town and Country Planning Act to make BNG mandatory (Schedule 7A). For BNG in Brent, that means showing a measured uplift via the Defra Biodiversity Metric and securing delivery (on-site or off-site) for at least 30 years. Include the metric version and publication date in submissions.
How does strategic significance in London affect my BNG Assessment in Brent?
Projects aligned with London’s Local Nature Recovery Strategy can receive a positive multiplier in the metric’s strategic significance scoring. Early alignment helps schemes needing London biodiversity net gain credits or off-site units.
Do I need a Biodiversity Net Gain Report for small sites in Brent?
Yes, small sites are within scope from 2 April 2024. Even modest proposals typically need a BNG Report (or BNG Assessment) with the small-sites metric, plus proportionate management commitments. This is now standard for BNG consultants London working in Brent.
