Do You Need a Biodiversity Gain Plan in Manchester?
You will need a Biodiversity Gain Plan in Manchester when your planning permission includes a condition tied to Biodiversity Net Gain. The Biodiversity Gain Plan sets out how the required uplift will be delivered on the ground, how it will be managed over time and who is responsible for securing it.
Without an approved Biodiversity Gain Plan, most developments in Manchester cannot legally start work, even if full planning permission has already been issued.
Planning officers in Manchester commonly request Biodiversity Gain Plan evidence where development may affect:
• Urban regeneration and housing areas across Manchester and Salford
• Brownfield and former industrial land in towns such as Bolton, Oldham and Rochdale
• Major transport and logistics schemes linked to the M60, M62, M56 and key rail routes
• River and canal corridors, floodplain habitats and wider green infrastructure
Incomplete or unclear Biodiversity Gain Plan information often leads to validation delays or added conditions later in the process.
We deliver Biodiversity Gain Plan services across Manchester, Salford, Bolton, Bury, Oldham, Rochdale, Stockport, Tameside, Trafford, Wigan and the wider surrounding areas within the city region.
Why Planning Authorities in Manchester Request a Biodiversity Gain Plan
Planning authorities across Greater Manchester require a Biodiversity Gain Plan because Biodiversity Net Gain is now a statutory duty under the Environment Act 2021. The Plan sets out the legally enforceable method for delivering the biodiversity improvements linked to a planning permission. Without an approved Plan, the BNG condition cannot be discharged and development cannot begin on site.

How the Biodiversity Gain Plan Process Works
We produce planning-ready BNG Assessments aligned to Manchester’s policy expectations.
Key BNG Deliverables for Manchester Projects
Your Biodiversity Gain Plan is prepared to meet the expectations of planning officers across Manchester and typically includes:
- A habitat delivery strategy that sets out how the required biodiversity uplift will be achieved within the city
- Mapped habitat parcels that provide clear, reliable plans linked to the approved Metric
- Optional integration with a Habitat Management and Monitoring Plan where long term management is required
- A submission ready document formatted for approval by Manchester City Council
This structure supports a smooth and lawful discharge of the BNG condition in Manchester.

FAQ - BGP in Manchester
Does a city centre tower scheme in Manchester require a Biodiversity Gain Plan?
Yes. High rise residential or commercial developments within Manchester city centre must comply with mandatory Biodiversity Net Gain legislation where applicable. A Biodiversity Gain Plan must demonstrate at least 10 percent measurable uplift compared to the approved baseline.
How can Biodiversity Net Gain be achieved on constrained inner city sites?
On tight urban plots, uplift may be delivered through biodiverse green roofs, podium planting, vertical greening systems and carefully designed courtyard landscapes. The Biodiversity Gain Plan must quantify these habitats accurately within the statutory Biodiversity Metric.
Does site clearance before planning permission affect the Biodiversity Gain Plan?
Yes. Baseline habitat value is calculated at the time of planning submission. Clearing vegetation prematurely can lead to incorrect baseline assumptions and potential enforcement or recalculation issues.
How are basement developments reflected in Biodiversity Net Gain calculations?
Where schemes include extensive basements or underground parking, available habitat area may be limited. The Biodiversity Gain Plan must reflect actual achievable habitat delivery and may require off site biodiversity units to achieve compliance.
Is off site Biodiversity Net Gain common for Manchester city schemes?
Yes. Due to density and site constraints, many city centre developments rely partly on registered off site biodiversity units. The Biodiversity Gain Plan must confirm legal securing and registration of those units.
Who approves the Biodiversity Gain Plan in Manchester?
Manchester City Council acts as the Local Planning Authority and is responsible for approving the Biodiversity Gain Plan prior to commencement.

How detailed must green roof proposals be within the Biodiversity Gain Plan?
Green roof proposals must include clear ecological specifications, substrate depth, planting composition and long term securing arrangements. Vague references to “extensive green roof” are unlikely to satisfy metric requirements.
Can temporary meanwhile uses affect Biodiversity Net Gain calculations?
Temporary site uses may influence habitat condition prior to submission. The Biodiversity Gain Plan must be based on accurate, up to date ecological survey data reflecting the site at submission stage.
What are common reasons Manchester Biodiversity Gain Plans are refused or delayed?
Delays frequently arise where metric outputs do not match architectural plans, habitat areas are overestimated or ecological design is not technically specified. Coordination between architect and ecologist is essential.
How can ProHort support Biodiversity Gain Plan approval in Manchester?
ProHort prepares compliant Biodiversity Gain Plans tailored to Manchester’s high density urban context. We ensure accurate metric modelling, realistic vertical habitat proposals and clear legal securing arrangements to reduce approval risk.
