BNG Credits Explained: A Plain-English Guide for Landowners & Developers
Introduction:
Biodiversity Net Gain (BNG) is one of the biggest changes to planning law in decades — but for many landowners and developers, it still feels confusing. What are BNG credits? Who needs them? Who can create them? And how does the new market actually work?
In this guide, we’ll break it down step by step.
What is Biodiversity Net Gain (BNG)?
BNG is a legal requirement under the Environment Act 2021. It means that most developments in England must deliver at least a 10% increase in biodiversity value compared to what was there before.
Developers can achieve this either onsite (by incorporating habitat creation into their schemes) or offsite (by purchasing BNG credits from other landowners.
What Are BNG Credits?
BNG credits represent units of biodiversity uplift created when land is restored, rewilded, or enhanced to improve its ecological value.
Each unit is calculated using a government-approved metric.
Units vary by habitat type, distinctiveness, and risk factors.
Credits are usually tied to a 30-year management agreement, ensuring that the habitat is maintained long-term.
Who Needs BNG Credits?
Developers who cannot achieve the full 10% uplift on their site.
This includes housebuilders, commercial developers, and infrastructure projects.
Without evidence of securing credits, planning permission may be delayed or refused.
Who Can Create BNG Credits?
Landowners who dedicate part of their land to habitat creation or enhancement.
This could be farmland, pasture, woodland, or even brownfield sites.
Landowners usually work with an ecologist and habitat management partner to register their credits.
By working with a broker like Taylor Edwards Group, landowners can connect directly with developers who need credits — unlocking a new, long-term income stream.
How Does the Market Work?
Think of it as a supply-and-demand chain:
Supply: Landowners create registered habitat banks with measurable biodiversity uplift.
Demand: Developers buy the necessary units to satisfy planning conditions.
Broker: Independent brokers like TEG connect both sides, facilitate pricing, and ensure the deal is compliant and discreet.
What Are BNG Credits Worth?
Market prices vary by region and habitat type. Current averages are between £20,000 and £30,000 per unit in England, with premium habitats or high-demand areas achieving higher values.
Why Work With a Broker?
BNG is still a new and evolving market. Working with an independent broker like TEG means:
Clarity — plain-English guidance through a complex process.
Connections — access to both verified landowners and active developers.
Confidence — deals are structured and completed professionally, without wasted time.
Key Takeaways

Developers who can’t deliver biodiversity uplift onsite must buy credits.
Landowners can create credits and generate long-term revenue.
Independent brokers like TEG sit in the middle, connecting supply and demand.
