Why you may choose to sell off-site biodiversity units
Under mandatory BNG legislation, developers must deliver a
habitatbiodiversitybanknetoperatorgain of 10%.If developers cannot achieve BNG on their own sites, they will have to make off-site gains by using off-site biodiversity units. Off-site means outside the red line boundary of the development that has planning permission requiring BNG.
You can sell biodiversity units to developers on:
- land you own
For the purposes of BNG, biodiversity is measured in standardised biodiversity units.
Your land will contain a

HowSelling in the BNG market is a choice for land managers. It is a potential source of revenue and could fund nature recovery work on your land. You may, for instance, choose to generate and sell biodiversity units alongside farming, creating income from land that may otherwise be unsuitable for food production.

Options for selling biodiversity units
There are 3 main ways you can sell to developments looking for off-site biodiversity units. Make an informed decision based on what is best for the land owner.
1. Sell biodiversity units independently
You’ll need to take full responsibility for following all the steps in
partnershipthis guidance.2. Work with
yourone or more partnersYou can team up with a local
authoritynon-governmental organisation (NGO) or other land managers. Depending on how many people you work with, you may be able to create large habitat banks. You would then sell biodiversity units as a group. As a group, you still need to follow all the steps in this guidance.If you choose this option, you need to make sure you work out:
- who is responsible for which activities
through3. Use a habitat bank operatorA habitat bank operator leases your land and pays you a fixed fee on a regular basis, for example, monthly or yearly. Typically, the operator will try to find you a buyer and sell to them; legally secure your land; register your gain site and record its allocation, so you would not need to follow these steps yourself.
Either the operator or the land manager may do the habitat creation, enhancement and management, as well as any reporting. You will need to agree all the details of who does what in your contract with the operator.
Make sure you check the contract with the operator to find out:
- who is responsible for which activities
how you’ll receive paymentthroughwhenaandbroker- what will happen if the habitat doesn’t reach the target habitat condition
if no units are sold within the period of the legal agreementonwhatawilltradinghappenplatform- what will happen if the habitat bank operator ceases trading

The 30-year BNG commitment starts from the completion of habitat enhancement works, as defined in your legal agreement.
You can begin habitat creation, enhancement and management on a gain site
readybefore allocating off-site units on it. This is called habitat banking. Or you can allocate the units and then begin the habitat work as soon as possible.You can sell different units on one gain site to different developers. You would need to follow the steps in this guidance for each allocation of units to a developer.
1. Find out
whathow many units you could sell and the habitat types you could createYou will need to consult a qualified ecologist who will do a survey and measure how many units you have on your existing habitat. There is guidance on how to do this, using the statutory biodiversity metric.

The purpose of the register is to show how and where developments are improving biodiversity off-site. It also prevents ‘double counting’, which would happen if the same unitsandwereallocateassignedthemto multiple developments. Sites on the register may be allocated to specific construction projects to help them achieve their biodiversity gain target. The register does not contain contact details of available gain sites and is not adevelopment‘matchmaking’beforeserviceortoafterconnectyoubuyersregister.and sellers.

7. Record the allocation of off-site units to a development
You (or the developer, with your permission) must record the allocation of off-site biodiversity gains to a development. This service will be available when BNG becomes mandatory.
8. Manage the habitat for at least 30 years
Off-site units must be maintained for at least 30 years following the completion of habitat enhancement works, as defined in your legal agreement.
If habitat creation, enhancement and management work has not started by the time you record the allocation of off-site units, this should start within 12 months of allocation.
