Neil Beamsley, Group Head of Biodiversity, Bellway Homes
“After an extensive design review, it became clear that achieving a 10% biodiversity gain onsite at our Harold’s Wood site near Romford wasn't feasible. We've therefore partnered with Nattergal to provide the necessary additional gains.
I’m delighted that we have been able to start our BNG delivery journey together with Nattergal. It’s been inspiring to see the diligence and integrity with which they approach their work.
In fact, our collaboration extends beyond BNG. They will also create a new habitat for a population of slow worms currently residing at Harold’s Wood, ensuring their safe relocation to facilitate development.”

Biodiversity Net Gain (BNG) is a planning requirement that ensures development leaves the natural environment in a measurably better state than before. Introduced under the Environment Act 2021, most developments in England must deliver a minimum 10% increase in biodiversity value.
BNG can be achieved through on-site habitat creation or enhancement, off-site biodiversity projects, or, as a last resort, statutory biodiversity credits. Biodiversity improvements must be maintained for at least 30 years, helping to create lasting benefits for wildlife, local communities, and the wider environment.
-
BNG units are a way for developers to meet their Biodiversity Net Gain (BNG) requirements by funding the creation or enhancement of habitats, such as grassland, woodland and wetlands, on a suitable site.
-
You should buy off-site Biodiversity Net Gain (BNG) units early in the planning application process, ideally after completing your initial ecology assessment and before submitting your formal planning application
-
No. BNG units are the measurable biodiversity gains created through habitat enhancement or creation and can be bought and sold on the biodiversity market.
BNG credits, by contrast, are statutory credits purchased from the Government as a last resort when suitable BNG units cannot be secured.
In short: units deliver biodiversity on the ground, while credits are a fallback option when units are unavailable.
-
We aim to make the process as quick and straightforward as possible:
Quote: We aim to provide a quote within 2 working days of receiving your biodiversity metric.
Invoice & Contract: Once you confirm you'd like to proceed, we can issue the invoice and prepare the contract within 1-2 working days, provided we have all the information we need.
Unit Allocation: After the contract has been signed, we can allocate your BNG units and provide your registration reference within 1-2 working days.
Natural England Registration: At this stage, our work is complete and the registration process moves to Natural England. Registration times can vary depending on demand but typically take 2-6 weeks.
-
BNG delivers advantages for both people and Nature:
Increased biodiversity and habitat connectivity.
Better access to green spaces, improving mental and physical well-being.
Enhanced ecosystem services, including flood management, carbon storage, and cleaner air.
Greater climate resilience for wildlife and landscapes.
-
Onsite: Preferred method — developers enhance biodiversity within the project site.
Offsite: If onsite gains aren’t possible, developers buy units from habitat restoration projects, like Nattergal. This method requires a legal agreement (e.g., Section 106 or conservation covenant) and land must be managed for biodiversity for at least 30 years.
Statutory Credits: A last resort if no other options exist.
