Have BNG units available? Register your supply.
BNG Sourced by Green Acres BNG matches developer requirements across England to supply from landowners, habitat bank operators and BNG providers. Tell us what you have and we will put it in front of the right developers. You pay an introduction fee only when an introduction leads to a sale.
- Developer requirements matched to your site on unit type, distinctiveness and location
- Your details are never published; developers see counts and outlooks until an introduction is made
- You agree price and terms directly with the developer
- Introduction fee only when an introduction leads to a sale
Register your BNG supply
Registered, in progress or not yet: tell us where the site is and what it could deliver.

Who this is for
- Landowners with a registered gain site and unallocated units
- Habitat bank operators looking for demand in their area
- Landowners considering a habitat bank who want to understand what it could earn
- Providers of hedgerow and watercourse units, which are often in short supply
How it works for providers
- Register your supply with the form above: location, register status, area, unit types and approximate units available.
- When a developer requirement matches your site on unit type, distinctiveness and location, we introduce you.
- You agree price and terms directly with the developer.
- Where our involvement results in an introduction, you pay us an introduction fee.
We never publish your details on the website. Developers see counts and outlooks, not names, until an introduction is made.
Not yet registered?
Read what a habitat bank earns for the economics, then tell us about the land. We can talk through registration, Section 106 agreements and conservation covenants from direct experience: Green Acres BNG runs two registered habitat banks of its own.
What developers are looking for
Demand is driven by the metric. Developers need units that match the type and distinctiveness of habitat they are losing, local enough to avoid the 0.75 or 0.5 multiplier, allocated quickly with documentation their ecologist can use. Sites that meet those needs sell; sites that do not, however well managed, sit unallocated.
| Supply that sells quickly | Supply that sells slowly |
|---|---|
| Medium distinctiveness grassland near a growth area | Upland or already semi-natural land far from development |
| Hedgerow and watercourse units in any region | Very high distinctiveness habitat with no matching losses nearby |
| Registered sites with a Section 106 or covenant already in place | Sites still in the registration process with no date |
| Providers who allocate fractions and supply documentation promptly | Minimum whole-unit sales and slow paperwork |
How introductions work in practice
When a developer requirement matches your site on unit type, distinctiveness and location, a specialist contacts you to confirm availability and your current terms. If you are happy to proceed, we introduce the developer, who agrees price and allocation directly with you. Where our involvement results in an introduction, you pay us an introduction fee, agreed in advance. There is no fee for registering, no exclusivity and no obligation to accept an introduction.
Which land creates the most units
A biodiversity unit measures the uplift between the land’s value to nature before and after your scheme, so the baseline decides almost everything. Improved pasture, arable, former quarries and colliery land score low at baseline and can create 4 to 8 units per hectare when turned to species-rich grassland, woodland or wetland. Land that is already semi-natural, such as upland rough grazing or an existing hay meadow, may create 1 to 2 units per hectare because there is less room to improve. Target condition matters too: a scheme that commits to good condition creates more units than one aiming for moderate, but carries more management risk over 30 years.
| Baseline | Target habitat | Indicative units per hectare |
|---|---|---|
| Arable or improved grassland | Species-rich neutral grassland, good condition | 5 to 8 |
| Arable or improved grassland | Mixed deciduous woodland | 4 to 6 at maturity, discounted for time to target |
| Improved pasture | Other neutral grassland, moderate condition | 2.5 to 3.5 |
| Upland rough grazing | Enhanced upland habitat | 1 to 2 |
Indicative, from registered area and units on Natural England’s biodiversity gain site register, checked 3 October 2026. Your ecologist’s baseline survey sets the real figure.
Section 106 agreement or conservation covenant
A gain site must be secured for at least 30 years. A Section 106 agreement is made with the local planning authority and is the route most councils know; it can take months to negotiate and the authority monitors compliance. A conservation covenant is made with a designated responsible body, which can be faster where the authority is slow and offers a specialist monitoring partner, for a fee. Both are recorded on the register and both are acceptable to developers and planning authorities. Our specialists have used Section 106 at Netherton Park and can discuss both routes.
What a good provider does
- Keeps the register entry current so developers can see unallocated units
- Allocates fractions and whole units promptly, with a clear allocation confirmation
- Supplies the metric extract, register reference and legal agreement summary developers need for the gain plan
- Prices transparently, with any minimum fraction or fee stated up front
- Monitors and reports on habitat condition so the 30-year commitment is credible
If your site is not yet registered
We can still log your intended supply and tell you where demand is. Our specialists have taken two sites through registration and can talk through the baseline survey, the metric, the habitat management and monitoring plan, the Section 106 or conservation covenant and Natural England’s process. Read what a habitat bank earns first for the economics.
Landowner and provider questions
Do you charge landowners to register?
No. The introduction fee applies only when an introduction leads to a sale.
Will you name my site to developers?
Only when we introduce you, with your agreement. The website shows counts and outlooks, never names.
Can I set a minimum sale or a reserve price?
Yes. Tell us your terms when you register and we only introduce requirements that fit them.
What if I only have a few units?
Small sites and fractions are often exactly what a minor development needs.
How is the introduction fee calculated?
It is agreed with you in advance as a percentage of the sale and invoiced only when the allocation completes.
Can Green Acres BNG help me register?
Our specialists have taken two sites through registration and can talk you through the process. We do not act as your ecologist or solicitor.
