What is Biodiversity Net Gain (BNG): BNG in Ealing (London)?
BNG in Ealing requires new development to leave the borough’s biodiversity in a measurably better state than before. Planning submissions must include a Biodiversity Net Gain Assessment, a BNG Survey and a Biodiversity Gain Plan approved by Ealing Council. The statutory requirement applies to major applications and has now expanded to small sites. Every biodiversity net gain assessment in Ealing must demonstrate how pre- and post-development habitats score under the biodiversity metric. The borough’s Local Plan, Green Infrastructure Strategy and Action Plan 2022 emphasise nature recovery, new habitat creation, SuDS and urban greening.
ACP Consultants supports developers at each stage, from baseline data gathering and GIS mapping to final planning sign-off.
In Ealing, developers must actively consider biodiversity from the earliest stages of site design, particularly given the borough’s mix of suburban neighbourhoods, urban centres and important green corridors such as parks, waterways and open spaces. These local characteristics influence both baseline habitat value and the opportunities available for enhancement, making early ecological input essential.
Project teams typically integrate BNG into schemes by combining habitat retention, enhancement and new green infrastructure. This often includes tree planting, green roofs, sustainable drainage systems and improvements to habitat connectivity. On more constrained sites, developers may also secure off-site biodiversity units where on-site delivery alone cannot achieve the required uplift.
Ealing’s planning approach places strong emphasis on green infrastructure, environmental quality and long-term sustainability. By aligning BNG strategies with these priorities, developers can strengthen planning submissions while delivering measurable ecological improvements. Taking a proactive approach to biodiversity net gain helps reduce planning risk, improve scheme design and ensure that environmental benefits are both achievable and maintainable over time.
Environment Act 2021 and Local BNG Policy: BNG in Ealing (London)
Ealing Council requires Biodiversity Net Gain (BNG) surveys and consultants to use DEFRA Metric 4.0 alongside planning validation requirements. Applications commonly reference the Ealing Action Plan 2022, Natural England guidance, and borough-level policies supporting green corridors, woodland links and urban habitat creation. Where developments cannot achieve net gain on-site, ACP can model off-site units or credit purchase in alignment with Ealing’s strategic nature priorities.
Our approach is transparent, reliable and aligned with the Environment Act 2021. This gives clients certainty during planning and ensures measurable biodiversity outcomes.
Using DEFRA’s Statutory Biodiversity Metric 4.0
The statutory metric is required for all biodiversity net gain assessments in Ealing. It scores habitats on distinctiveness, condition, connectivity and strategic significance. ACP Consultants uses the metric to:
- Map baseline habitats through a BNG Survey in Ealing
- Model post-development habitat units
- Identify measurable uplift
- Support long-term Habitat Monitoring and Management Plans (HMMP)
- Provide evidence for S106 or legal agreements where required
All data is prepared for local authority scrutiny, with clear assumptions and transparent reporting.
Habitat Mapping and Strategic Location in Ealing
Habitat mapping plays a key role in Biodiversity Net Gain assessments in Ealing, helping identify ecological corridors, parks, green infrastructure networks and areas of strategic importance. These spatial layers inform how habitats are valued within the statutory biodiversity metric, particularly through the “strategic significance” multiplier, which can influence overall biodiversity unit calculations.
Positioning habitat enhancements in areas that align with local ecological priorities can improve both biodiversity outcomes and planning acceptability. In Ealing, this may include strengthening connections between parks, enhancing urban green corridors or supporting Local Nature Recovery priorities where relevant.
Our consultants interpret local mapping data, planning policy and ecological networks to ensure that BNG proposals reflect site-specific opportunities rather than generic design approaches. By aligning habitat creation and enhancement with Ealing’s wider environmental strategy, developers can deliver more robust biodiversity outcomes while improving the likelihood of a smooth planning process.
Local Policy and Planning Context for BNG in Ealing
Ealing’s planning framework reinforces the national Biodiversity Net Gain requirement through its emphasis on green infrastructure, sustainable development and environmental quality. Local policy supports measurable biodiversity improvements alongside wider objectives such as urban greening, climate resilience and landscape enhancement.
For developers, this means that BNG submissions must do more than meet the minimum 10% uplift. Proposals should demonstrate how biodiversity enhancements integrate with site design, contribute to local ecological networks and align with planning expectations set out in the Local Plan and supporting guidance.
A well-structured BNG strategy, supported by clear metric calculations, habitat mapping and long-term management proposals, helps streamline the validation process and reduce planning risk. By addressing both national requirements and Ealing’s local policy context, applicants can create schemes that are not only compliant but also better aligned with the borough’s long-term environmental priorities.

Off-site Biodiversity Units and Delivery in Ealing
Where a development in Ealing cannot achieve the required biodiversity uplift on-site, off-site biodiversity units may form part of a compliant delivery strategy. These units are generated from habitat enhancement projects elsewhere and must meet strict requirements around measurability, additionality and long-term management.
Developers must demonstrate that off-site solutions are appropriate, available and aligned with planning policy. This includes identifying suitable habitat banks, verifying unit availability and ensuring that all ecological and legal requirements are satisfied.
ACP Consultants supports this process by assessing off-site options, modelling biodiversity unit requirements and integrating them into a compliant Biodiversity Gain Plan. We also provide clear metric outputs, mapping and reporting so that planning officers can verify how biodiversity gains will be delivered and maintained.
By taking a structured and transparent approach, developers can use off-site solutions effectively while ensuring that projects remain policy-compliant and deliver measurable ecological improvements.

BNG Survey / Biodiversity Net Gain Surveys in Ealing
A BNG survey in Ealing establishes the baseline ecological condition of a site, including habitat type, condition and spatial distribution using UKHab classification and GIS mapping. Our ecologists assess vegetation, trees, water features and land parcels to generate accurate baseline biodiversity unit values.
In Ealing, surveys often need to reflect a mix of suburban gardens, urban corridors, parks and designated green spaces, which can significantly influence biodiversity value and planning expectations. Early-stage survey work helps identify constraints, highlight enhancement opportunities and ensure that the biodiversity metric is based on robust and defensible data.
These surveys form the foundation for all subsequent BNG assessments and are critical for demonstrating compliance with local planning validation requirements.
BNG Assessment / Biodiversity Net Gain Assessments in Ealing
A BNG assessment in Ealing applies DEFRA’s Statutory Biodiversity Metric 4.0 to quantify habitat losses and gains. This includes modelling baseline conditions, post-development habitat proposals and applying appropriate risk and temporal multipliers to demonstrate the required uplift.
Given Ealing’s varied development context, assessments must consider site-specific factors such as urban density, green infrastructure links and local ecological priorities. Our assessments include detailed metric tables, GIS outputs and clear justification for habitat enhancement strategies.
By presenting accurate and transparent calculations, we help ensure that biodiversity net gain proposals are both deliverable and aligned with Ealing Council’s planning expectations.
Biodiversity Gain Plan (BGPs) in Ealing
A Biodiversity Gain Plan (BGP) sets out how a development will achieve and maintain biodiversity net gain in line with the statutory framework. It typically includes metric outputs, habitat proposals, off-site unit strategies (where required) and long-term management commitments.
In Ealing, BGPs must align with both national requirements and local planning policy, ensuring that habitat enhancements contribute to wider green infrastructure and environmental objectives. We prepare clear, structured BGPs that support validation and demonstrate how biodiversity improvements will be secured over time.
A well-prepared BGP provides confidence to planning officers and helps streamline the approval process.
Habitat Monitoring and Management Plan (HMMP) in Ealing
A Habitat Monitoring and Management Plan (HMMP) defines how habitats will be managed, monitored and maintained over a minimum 30-year period. It includes maintenance schedules, monitoring intervals, performance targets and adaptive management measures.
In Ealing, where developments often incorporate urban green infrastructure, HMMPs ensure that planted and created habitats establish successfully and continue to deliver biodiversity benefits. The plan also provides a clear framework for long-term stewardship and compliance with planning obligations.
Effective monitoring and management are essential to demonstrate that biodiversity gains are not only achieved but sustained over time.
BNG Report / Biodiversity Net Gain Report in Ealing
A BNG Report consolidates all ecological survey data, biodiversity metric calculations and habitat proposals into a single planning-ready document. It provides a clear and structured summary of how biodiversity net gain will be achieved.
In Ealing, where sites may vary from urban infill to larger redevelopment areas, the report must clearly demonstrate that proposals are realistic, measurable and aligned with planning policy. This includes baseline data, post-development scenarios, mapping outputs and justification of any off-site units.
A robust BNG Report helps reduce validation delays, supports planning review and provides a transparent audit trail for biodiversity delivery.
