Submit a biodiversity gain plan
A biodiversity gain plan shows how a development will achieve biodiversity net gain.
Applies to England
Biodiversity net gain (BNG) is mandatory from 12 February 2024.
The purpose of the plan is to:
- clearly and consistently demonstrate how development proposals meet the statutory requirements
- provide evidence for your BNG decisions
- help local planning authorities (LPAs) to determine whether the development meets the BNG requirements

Phased developments
For phased developments there are separate requirements. You will need to complete:
- an overall biodiversity gain plan
- a phase biodiversity gain plan
Templates for these will be available soon.
Submit your plan
You can submit the biodiversity gain plan to your LPA after they approve your planning application.
Your planning permission includes the biodiversity gain condition, so you cannot start the development until the LPA approves your biodiversity gain plan and biodiversity metric tool calculation.
Get a decision
The LPA has 8 weeks to approve or refuse your biodiversity gain plan. If they approve it, you can start the development.
If you do not meet your BNG requirements, the LPA can take enforcement action against you. You may be in breach of:
- planning conditions
- planning obligations
- your legal agreement
