At Maydencroft, we help developers, planners, and land promoters integrate Biodiversity Net Gain (BNG) seamlessly into their planning projects — ensuring compliance, design efficiency, and ultimately, planning application success. Our proactive, collaborative approach ensures that every project delivers measurable biodiversity gains — helping clients meet their obligations while contributing to a more nature-positive future.
Biodiversity Net Gain for Planning and Development
At Maydencroft, we help developers, planners, and land promoters integrate Biodiversity Net Gain (BNG) seamlessly into their planning projects — ensuring compliance, design efficiency, and ultimately, planning application success. Our experienced ecologists and land management professionals work closely with design teams from the earliest stages to deliver robust, evidence-based outcomes that meet both policy and ecological objectives.
BNG Baseline Assessments and Feasibility
Every successful BNG strategy begins with a clear understanding of the site. As part of the feasibility stage, we review site constraints, development layouts, and landscape opportunities to determine how biodiversity gains can be realistically achieved — whether on-site, off-site, or through a combination of both. This early input helps to shape design proposals that are both ecologically sound and commercially viable.
Our Consultants then carry out detailed BNG Baseline Assessments to establish existing habitat types, condition, and area. We use the latest Defra Biodiversity Metric to calculate baseline biodiversity units and identify the potential for on-site enhancement or creation.
Integrating BNG into the Design Process
We believe that BNG should be a design consideration from the outset, not an afterthought. Our ecologists collaborate closely with project architects, landscape designers, and planning consultants to embed biodiversity enhancement into the site design. This ensures that the development layout maximises habitat opportunities while meeting planning policy and client objectives.
Planning Documentation and Submission Support
Maydencroft provides all the required documentation to support a planning submission, including BNG Metric Calculations, baseline habitat maps and draft Biodiversity Gain Plans.
Following approval, we also assist with discharging planning conditions relating to Habitat Management and Monitoring Plans (HMMPs) or Landscape and Ecological Management Plans (LEMPs) as required. Our team ensures these documents are detailed, practical, and aligned with long-term management responsibilities.
Off-Site Units and Broker Introductions
Where a development cannot achieve the required biodiversity gains on-site, we can facilitate access to off-site BNG units. Through our trusted network of BNG brokers and habitat unit providers, we can introduce developers to suitable schemes and assist with the process of purchasing biodiversity units, ensuring full compliance with local and national frameworks.
Supporting Compliance and Application Success
From feasibility through to post-consent management, Maydencroft provides a complete, end-to-end BNG service that supports planning success. Our proactive, collaborative approach ensures that every project delivers measurable biodiversity gains — helping clients meet their obligations while contributing to a more nature-positive future.
