Do You Need a Biodiversity Gain Plan in Greater Manchester?
You’ll need a Biodiversity Gain Plan in Greater Manchester 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.
Planning officers in Greater Manchester most frequently require formal Biodiversity Gain Plan evidence where development affects:
- High-density urban regeneration and housing delivery across Manchester, Salford, Bolton and OldhamÂ
- Brownfield and former industrial land redevelopment across Rochdale, Tameside and WiganÂ
- Strategic transport-led and logistics development along the M60, M62, M56 and regional rail corridors, particularly around Trafford Park and south ManchesterÂ
- River corridors, canals, floodplains and urban green infrastructure associated with the Irwell, Mersey, Rochdale Canal and Bridgewater CanalÂ
If this evidence isn’t provided in the correct format, many planning applications aren’t validated at all, or they are delayed by conditions later in the process.
We provide Biodiversity Gain Plan services across: Manchester, Salford, Bolton, Bury, Oldham, Rochdale, Stockport, Tameside, Trafford, Wigan and all surrounding boroughs across the city region.Â
Why Planning Authorities in Greater Manchester Request a Biodiversity Gain Plan
Planning Authorities across Greater Manchester require a Biodiversity Gain Plan because Biodiversity Net Gain is now a statutory requirement under the Environment Act 2021. The Plan provides the legally enforceable route for delivering biodiversity improvements tied to a specific planning permission. Without an approved Plan, the BNG condition cannot be lawfully discharged, and development cannot commence on site.Â

How the Biodiversity Gain Plan Process Works
We produce planning-ready BNG Assessments aligned to Greater Manchester’s policy expectations.
Key BNG Deliverables for Greater Manchester Projects
Your Biodiversity Gain Plan is structured to meet Greater Manchester‘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 Greater Manchester can be discharged cleanly and lawfully.

FAQ - BGP in Greater Manchester
How does Biodiversity Net Gain operate across Greater Manchester’s ten boroughs?
Although Greater Manchester functions as a combined authority area, Biodiversity Gain Plans are approved by the individual metropolitan borough councils. Each qualifying development must demonstrate a minimum 10 percent Biodiversity Net Gain in accordance with national legislation.
Do high density residential developments in Manchester city centre require a Biodiversity Gain Plan?
Yes. High rise and high density residential schemes are not exempt. The Biodiversity Gain Plan must quantify habitat losses and demonstrate measurable uplift, even where delivery relies on green roofs, podium planting or limited on site space.
How are multi borough or boundary sites treated?
Where a development straddles borough boundaries, coordination between authorities may be required. The Biodiversity Gain Plan must clearly define habitat calculations and securing arrangements for each relevant Local Planning Authority.
Can regeneration of former industrial land avoid Biodiversity Net Gain requirements?
No. Previously industrial or vacant land does not remove the statutory requirement. The Biodiversity Gain Plan must rely on current ecological survey data and confirm compliance with the 10 percent uplift requirement.
How are river corridors and flood risk areas addressed?
Greater Manchester includes river systems such as the Irwell and Mersey. Where development affects these corridors, the Biodiversity Gain Plan should demonstrate how riparian habitats are enhanced while remaining compatible with flood risk management strategies.
Is early Biodiversity Metric modelling important on city centre schemes?
Yes. Early modelling helps identify whether on site habitat creation is sufficient or whether off site biodiversity units will be required. Late stage metric revisions frequently cause approval delays.
Can biodiversity units be sourced from elsewhere within Greater Manchester?
Where on site uplift is insufficient, developers may secure registered off site biodiversity units. The Biodiversity Gain Plan must confirm that those units are legally secured and compliant with statutory requirements.
What documentation must accompany a Biodiversity Gain Plan submission?
A compliant submission typically includes statutory Biodiversity Metric calculations, baseline habitat surveys, post development habitat plans and confirmation of legal securing mechanisms. Incomplete documentation can delay approval.
What are common approval risks in complex urban schemes?
Risks include discrepancies between ecological reports and architectural layouts, inaccurate habitat area measurements and insufficient ecological specification for green roofs or landscaped terraces. Coordination between consultants is critical.
How can ProHort support Biodiversity Gain Plan submissions in Greater Manchester?
ProHort prepares technically robust Biodiversity Gain Plans aligned with metropolitan authority expectations. We ensure accurate metric modelling, realistic habitat delivery strategies and clear securing arrangements to minimise pre commencement delay.
