In simple terms, you’ll need a Biodiversity Gain Plan for your Buckinghamshire site if your planning permission includes a condition linked to Biodiversity Net Gain (BNG). The Biodiversity Gain Plan is the document that shows how the required biodiversity improvement will actually be delivered, how it will be maintained, and who is responsible for it.
Without an approved Biodiversity Gain Plan in place, many developments cannot legally begin, even where planning permission has already been granted.
In Buckinghamshire, Biodiversity Gain Plan evidence is most frequently required for development involving:
• Strategic housing and mixed-use growth around Aylesbury, High Wycombe and growth corridors
• Redevelopment of former industrial, mineral and employment sites
• Infrastructure and transport-related schemes associated with major roads and rail corridors
• Greenfield edges, agricultural land and woodland interfaces near rural settlements and landscape designations
Applications submitted without compliant BNG evidence are regularly delayed or subject to planning conditions.
We provide Biodiversity Gain Plan services across Milton Keynes, Aylesbury, High Wycombe, Amersham, Chesham, Marlow, Beaconsfield and all surrounding towns and rural areas across Buckinghamshire.
Planning Authorities across Buckinghamshire require a Biodiversity Gain Plan because Biodiversity Net Gain is now a legal requirement under the Environment Act 2021 and must be formally secured through the planning system. The Plan provides the legally enforceable route for delivering and maintaining biodiversity improvements linked to a specific permission. Without an approved Biodiversity Gain Plan, the BNG condition cannot be lawfully discharged, and development cannot commence on site.
We prepare compliant, planning-ready Biodiversity Gain Plans that meet Buckinghamshire’s policy requirements and keep your BNG on track.
Your Biodiversity Gain Plan is structured to meet Buckinghamshire’s planning requirements and typically includes:
Habitat delivery strategy — how and where biodiversity uplift will be achieved
Mapped habitat parcels — legally reliable plans linking habitats to the approved metric
Optional integration with a Habitat Management & Monitoring Plan (HMMP) where 30-year management is required
Submission-ready planning document — formatted for Local Planning Authority approval
This ensures your BNG condition in Buckinghamshire can be discharged cleanly and lawfully.
We assess your existing BNG assessment, site layout and planning condition.
Habitat delivery proposals, mapping and management requirements are drafted.
The plan is aligned with your build programme and any wider ecological or planning documents.
We respond to any LPA queries or amendments required.

Yes. Where development falls within the statutory scope of Biodiversity Net Gain legislation, a Biodiversity Gain Plan must demonstrate at least 10 percent measurable uplift compared to the approved baseline habitat value.
Where development is permitted within or adjacent to the Chiltern Hills National Landscape, the Biodiversity Gain Plan must demonstrate measurable uplift while ensuring habitat proposals are appropriate for sensitive chalk and woodland landscapes.
Yes. Infrastructure projects within Buckinghamshire must comply with statutory Biodiversity Net Gain requirements where applicable. The Biodiversity Gain Plan must accurately quantify habitat impacts associated with construction and permanent land take.
Where development is permitted within Green Belt areas, Biodiversity Net Gain legislation still applies. The Biodiversity Gain Plan must demonstrate compliant uplift alongside planning policy considerations.
Even modest developments may fall within statutory scope. The Biodiversity Gain Plan must demonstrate measurable uplift supported by accurate ecological survey and metric calculations.
Buckinghamshire Council acts as the Local Planning Authority and is responsible for reviewing and approving Biodiversity Gain Plans prior to commencement.

Woodland and mature tree habitats can carry higher distinctiveness values. The Biodiversity Gain Plan must accurately assess baseline habitat condition and ensure any losses are properly addressed in accordance with national guidance.
Yes. On larger rural or estate sites, habitat creation and enhancement across wider landholdings may contribute to measurable uplift if legally secured and correctly quantified within the Biodiversity Metric.
Risks include unrealistic habitat proposals on chalk soils, inconsistencies between site layout and metric outputs and failure to clearly demonstrate long term securing arrangements.
ProHort prepares technically compliant Biodiversity Gain Plans tailored to Buckinghamshire’s Chilterns and rural planning context. We ensure accurate metric modelling, realistic habitat proposals and clear securing mechanisms to minimise pre commencement delay.
