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 Oldham
- Brownfield and former industrial land redevelopment across Rochdale, Tameside and Wigan
- Strategic transport-led and logistics development along the M60, M62, M56 and regional rail corridors, particularly around Trafford Park and south Manchester
- River corridors, canals, floodplains and urban green infrastructure associated with the Irwell, Mersey, Rochdale Canal and Bridgewater Canal
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.
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.

FAQ - BGP in Greater Manchester
If I have planning permission in Greater Manchester, why am I now being asked for a Biodiversity Gain Plan?
This usually means your Greater Manchester planning permission includes a Biodiversity Net Gain (BNG) condition. Even with permission granted, you cannot legally start work until a Biodiversity Gain Plan is approved by the Local Planning Authority. This applies across councils such as:
- Manchester City Council – https://www.manchester.gov.uk
- Salford City Council – https://www.salford.gov.uk
- Bolton Council – https://www.bolton.gov.uk
- Trafford Council – https://www.trafford.gov.uk
Until the Plan is approved, the BNG condition cannot be discharged and development cannot lawfully proceed.
My architect or developer says I need a Biodiversity Gain Plan in Greater Manchester — what actually is it?
A Biodiversity Gain Plan is the legal document that sets out how your Greater Manchester development will deliver its required biodiversity improvement. In simple terms, it explains:
- What habitats will be created or enhanced
- Where this will take place (on or off site)
- How it will be delivered and maintained
- And who is responsible for delivery
It is the document the council uses to sign off the BNG condition and allow work to begin on site.
How long does it take to prepare a Biodiversity Gain Plan in Greater Manchester?
For most Greater Manchester sites, an initial Biodiversity Gain Plan can typically be prepared within 10 working days, subject to habitat data availability and site complexity. Timescales may increase where off-site units, phased development or large sites are involved.
Is a Biodiversity Gain Plan in Greater Manchester different from a BNG Assessment?
Yes. A BNG Assessment calculates biodiversity loss and gain, while the Biodiversity Gain Plan is the legal delivery document that shows how that gain will actually be implemented, managed and enforced for your Greater Manchester development. Both are usually required at different stages of the planning process.
