What is Biodiversity Net Gain (BNG) in Barking and Dagenham (London)?
Biodiversity Net Gain (BNG) means your development must leave biodiversity in a better state than before. Under the statutory framework introduced by the Environment Act 2021 via Schedule 7A of the Town and Country Planning Act 1990 most planning permissions in England must now meet a minimum net gain of +10% relative to the pre-development biodiversity value.
In Barking and Dagenham, the local planning authority expects developments to integrate biodiversity net gain Barking and Dagenham principles through site assessments, habitat creation, monitoring and management, in line with the borough’s Local Plan and supporting SPD.
For developers, that means commissioning specialist BNG survey in Barking and Dagenham early to inform design and avoiding costly policy obstacles. Engaging qualified BNG consultants ensures that your BNG metric calculations and delivery plans are technically robust and aligned with the local planning agenda.
In practice, this means biodiversity is now a core part of the planning and design process rather than a secondary consideration. In Barking and Dagenham, where sites are often constrained by urban density and regeneration pressures, achieving the required biodiversity uplift requires a clear, evidence-led approach. This may include green roofs, urban greening, sustainable drainage systems and habitat connectivity measures integrated early into the design.
The Statutory Biodiversity Metric is used to quantify baseline and post-development biodiversity value in measurable units. This relies on accurate habitat mapping, condition assessment and well-justified enhancement proposals. Poorly evidenced submissions can lead to delays, additional information requests or redesign.
BNG is also not just about achieving a numerical uplift. Local planning authorities may expect proposals to contribute to wider ecological networks, green infrastructure and Local Nature Recovery priorities. In Barking and Dagenham, this is particularly relevant where improving connectivity and urban biodiversity is a key planning objective.
Environment Act 2021 and Local BNG Policy in Barking and Dagenham (London)
The Environment Act 2021 mandates that, subject to certain exemptions, all new developments in England must achieve a biodiversity gain condition currently targeting at least 10%.
Within Barking and Dagenham, the council’s Local Plan 2020-2037 (adopted 18 September 2024) sets out the strategic planning context including biodiversity expectations.
The borough’s Biodiversity Annex / SPD emphasises that developments must: conduct accurate ecological surveys of protected and priority species/habitats; prepare clear enhancement proposals; and deliver long-term management.
Draft policy DMNE3 specifically highlights that proposals “must demonstrate a minimum of 10% biodiversity net gain (BNG) using the Biodiscovery metric” in Barking and Dagenham.
These policies mean that for any scheme in Barking and Dagenham you need to work with an experienced partner who understands BNG consultants London and the local validation requirements to satisfy the planning authority.
Using DEFRA’s Statutory Biodiversity Metric 4.0
To quantify biodiversity net gain, you’ll need to use the Biodiversity Metric 4.0 (or its successor) published by DEFRA.
The process involves:
- Baseline survey of habitats and features on-site.
- Applying the metric to derive a current biodiversity value.
- Predicting post-development biodiversity value via habitat creation, enhancement or off-site units.
- Demonstrating the target net gain (typically +10% in Barking and Dagenham) and preparing a monitoring and management regime.
Given the local context of Barking and Dagenham including priority habitats along the River Roding corridor, urban river frontage and constrained sites your metric must reflect local conditions accurately. The council’s Biodiversity SPD emphasises enhancing strategic wildlife corridors and prioritising habitat creation aligned with the London Green Grid.
Working with our BNG consultants means your metric is defensible, technically sound and aligned with both national and local policy.

Frequently Asked Questions
Biodiversity Net Gain (BNG) in Barking and Dagenham is a mandatory planning requirement for most development proposals, ensuring that new schemes deliver at least a 10% measurable increase in biodiversity value compared to pre-development conditions. Under the Environment Act 2021, developers must demonstrate compliance using the Defra Biodiversity Metric, with outcomes secured for a minimum of 30 years through planning conditions or legal agreements. In Barking and Dagenham, BNG expectations are applied alongside local planning policies, green infrastructure priorities and site-specific ecological constraints, meaning early ecological input is essential to avoid delays at validation or determination stage.
What is the minimum biodiversity net gain requirement in Barking and Dagenham?
Developers need to demonstrate a minimum net gain of +10% biodiversity value for most developments in Barking and Dagenham. This threshold is set under the national statutory framework and reflected in the borough’s policy.
In practical terms, for a development proposal in Barking and Dagenham you will calculate your baseline habitat value, predict the post-development value, and ensure, after mitigation and enhancement, a gain of at least 10%. Serious local policy scrutiny applies.
How early should I engage BNG consultants in Barking and Dagenham?
Early engagement is key. Commissioning a BNG survey in Barking and Dagenham at the very start of scheme design helps identify ecological constraints, habitat opportunities, whether off-site units are needed, and informs metric modelling. This approach reduces risk of late surprises, planning delays or requirement for off-site credits.
Can off-site biodiversity units or credits be used for BNG in Barking and Dagenham?
Yes, where on-site biodiversity net gain cannot deliver the required target (common in dense urban sites in Barking and Dagenham) you can use registered off-site biodiversity units or credits. However, you still must justify why on-site delivery is limited and show that off-site delivery is robust, additional, measurable and linked to the local ecological context.
What habitats or species are particularly relevant for Barking and Dagenham?
Local guidance in Barking and Dagenham emphasises priority habitats including river corridors (River Roding, River Beam), strategic green infrastructure, sites of borough importance for nature conservation, and urban edge-habitats. Your survey should account for the borough’s unique context (industrial-edge, riverside, green corridor) and your enhancement plan should align accordingly.
How long must a monitoring and management plan last in Barking and Dagenham?
The Draft policy indicates that developments must prepare a long-term monitoring and management plan of biodiversity net gain sites for a period of 30 years in Barking and Dagenham. Poorly defined management plans are flagged by the council, so working with qualified consultants ensures that duration, responsibilities and habitat interventions are clearly documented.
What happens if I don’t meet the BNG requirement in Barking and Dagenham?
Failure to meet the BNG requirement in Barking and Dagenham can lead to refusal of planning permission or conditions preventing commencement. The council’s Local Plan and SPD require developers to demonstrate compliance and delayed or insufficient BNG work can cause significant cost and risk. Engaging specialist consultants mitigates that risk.
BNG in Barking and Dagenham council what does the council expect from applicants?
Barking and Dagenham Council expects every qualifying Barking and Dagenham development to submit:
- a Biodiversity Net Gain Assessment using the statutory DEFRA metric,
- a Biodiversity Net Gain Plan (often called a BNG Action Plan / BNG Gain Plan), and
- a 30-year Habitat Monitoring and Management Plan.
In simple terms, the council needs proof that biodiversity net gain in Barking and Dagenham is deliverable, funded and trackable. This links to wider local environmental initiatives in the borough, including restoration of riverside habitats and green corridors and improving biodiversity in urban areas as regeneration continues.
ACP Consultants produces all of these documents to Barking and Dagenham council standards and submits them as part of your planning application pack.
BNG in Barking and Dagenham map do I need habitat mapping and a constraints map?
Yes. A “BNG in Barking and Dagenham map” is typically required as part of your BNG survey and BNG Assessment. It shows the baseline habitats on site, proposed habitat creation and enhancement, and how those link into local green corridors. Barking and Dagenham Council expects clear mapping because the borough is going through intense regeneration, including Barking Riverside and Thames-side brownfield redevelopment.
ACP Consultants prepares GIS-linked habitat mapping and metric mapping to evidence biodiversity net gain in Barking and Dagenham for planners. That mapping also supports climate change adaptation strategies by showing floodplain grassland, reedbeds and SuDS planting, and demonstrates wildlife conservation projects for species using riparian and brownfield mosaic habitat in Barking and Dagenham.
BNG in Barking and Dagenham 2021 and BNG in Barking and Dagenham 2022 what changed?
BNG in Barking and Dagenham 2021 was influenced by early policy drivers from the Environment Act 2021, signalling that biodiversity net gain would become mandatory. By 2022, Barking and Dagenham Council was already asking developers to evidence biodiversity net gain in Barking and Dagenham at +10%, using the emerging DEFRA metric and committing to long-term management.
Today, that position is firm. The council wants a BNG Assessment, BNG Gain Plan and monitoring plan that locks in measurable uplift for at least 30 years.
ACP Consultants tracks these policy steps so we can demonstrate compliance history and justify deliverability to case officers.
Barking and Dagenham development and permitted development Barking and Dagenham do small schemes still have to deliver biodiversity net gain?
Many Barking and Dagenham development proposals, including infill housing, change-of-use and industrial refurbishment, must now account for biodiversity net gain even if they look minor.
Some very small or permitted development Barking and Dagenham schemes may qualify for reduced reporting or a BNG Exemption Statement, but you still need to evidence why you cannot practically deliver habitat uplift and how you will avoid biodiversity harm. ACP Consultants can produce that BNG Exemption Statement, referencing Barking and Dagenham council policy, and confirm whether biodiversity net gain applies to your permitted development class in Barking and Dagenham.
We will also advise on climate change adaptation strategies such as green roofs, rain gardens and SuDS planting, which can deliver biodiversity in urban areas while improving flood resilience. These measures are often accepted by planning as part of local environmental initiatives and wildlife conservation projects in dense sites.
Barking and Dagenham building control contact number, and how does the Barking and Dagenham app fit into the process?
For building regulation matters (structure, fire, drainage, safety) you should speak to Building Control for Barking and Dagenham. The council lists a Building Control Manager contact (for Barking and Dagenham / Be First) and provides direct telephone contacts for residents, alongside a general council contact line. Please look at the council website for the most up-to-date information.
This sits alongside planning control. Planning officers will check the biodiversity net gain in Barking and Dagenham, while Building Control checks technical build compliance.
Many applicants now submit documents and track progress through the Barking and Dagenham app / online portals provided by the council and Be First (the borough’s regeneration company).
ACP Consultants can assist you with your BNG Assessment, BNG Report, and Habitat Monitoring and Management Plan, aligning with what planning officers expect and can be submitted for planning consideration.
How does biodiversity net gain link to climate change adaptation strategies and carbon offset projects in Barking and Dagenham?
Biodiversity net gain in Barking and Dagenham is no longer treated as “ecology only”. The council connects habitat creation to climate change adaptation strategies such as floodplain restoration, reedbed enhancement along river corridors and green roofs in Barking Riverside. These measures slow water, cool hard surfaces and protect future residents.
In parallel, developers are increasingly asked about carbon offset projects and low-carbon design. While carbon offset projects focus on residual carbon, biodiversity net gain focuses on measurable habitat uplift. Delivering both together, plus visible wildlife conservation projects, helps demonstrate sustainability, supports local environmental initiatives, and strengthens planning justification for Barking and Dagenham development.
ACP Consultants frames these benefits clearly in your BNG Report / Biodiversity Net Gain Report so case officers can see how biodiversity in urban areas, drainage planting and habitat corridors offer both ecological value and resilience.
