What you can count towards a development鈥檚 biodiversity net gain
How developers can use habitat creation or enhancements to count towards their biodiversity net gain (BNG).
Applies to England
If you already need to create or enhance habitat as part of your development, you may be able to count this towards your 10% biodiversity net gain (BNG).听听
Examples of other schemes you may be able to count include:听
- 鈥宧abitat creation or enhancement delivered to comply with certain statutory obligations or policies, such as green infrastructure, sustainable drainage, or nutrient mitigation听
- 鈥宮itigation and compensation measures for protected sites and species (for example, )
- providing river basin management plan (RBMP) mitigation and enhancement measures听
What you can count in full, in part or not at all
You cannot include some habitat schemes in BNG calculations at all. There are other schemes that you can include:听
- in full - for enhancing actions, such as green infrastructure (a developer can satisfy all their BNG requirements through the works, receiving 110% of their biodiversity units through them)听
- in part - for mitigation and compensation actions, such as nutrient mitigation (at least 10% of the developer鈥檚 biodiversity units must come from additional activities other than mitigation and compensation)听听
Example: a developer already has to do nutrient mitigation to compensate for impacts on protected species. This counts in part towards BNG, so at least 10% of their total (110%) BNG should come from measures which are not nutrient mitigation. The development needs to achieve 11 biodiversity units, so nutrient mitigation can count for 10 of these units. At least 1 unit should come from other on-site or off-site gains or statutory biodiversity credits.听
The same rules apply to what you can count whether on-site or off-site. For example, if something can only count in part when taking place off-site, it can also only count in part when on-site, and vice versa.听
How to count other schemes towards your BNG
If you want to count other habitat creation or enhancement scheme work towards your BNG, you must include it in your:听
- metric calculation听听
- biodiversity gain plan听
For example, if you are counting work for another scheme in part towards your BNG, you should enter it into your metric calculation like any other habitat creation or enhancement work. You should also explain clearly in your biodiversity gain plan how at least 10% of your BNG is coming from habitat creation or enhancement outside the scheme.听

| River basin management plan (RBMP) mitigation | In part |
| Nutrient neutrality or mitigation | In part |
| Suitable alternative natural green space (SANG) | In part |

| Mitigation or compensation to a special area of conservation, special protection area, or protected species | In part |
| Mitigation or compensation to functionally linked land (FLL) | In part |
| NatureSpace district licensing | In part |

-
Updated to add that NatureSpace鈥檚 district licensing scheme counts in part towards BNG, and clarify that counting Natural England鈥檚 district level licensing (DLL) in part towards BNG is not available yet. Natural England is working on how DLL may be able to count towards BNG in future.
-
Updated to clarify that counting district licensing in part towards BNG is not available yet. Natural England is working on how it may be able to count towards BNG in future.
-
Updated to state that biodiversity net gain (BNG) is mandatory from 12 February 2024. Also completely updated throughout to clarify the rules on what you can count in full, in part or not at all, including a table showing rules for specific schemes, and how to count other schemes towards BNG.
