5 Key Points about Biodiversity Net Gain for Small Developers

published May 23, 2024

Biodiversity net gain (BNG) regulations, emphasising the enhancement of biodiversity in construction projects, are a critical component of the UK’s Environmental Act 2021. Since February 12, 2024, all major developments in England have been mandated to demonstrate a minimum 10% increase in biodiversity to secure planning permission, with small developments having a grace period until April 2, 2024.

For small developers, navigating the new BNG requirements can seem daunting. Here’s what you need to know:

1. A Response to Biodiversity Decline

The implementation of BNG is a direct response to the alarming decline in the UK’s biodiversity. The State of Nature report highlighted a 19% decline in species since 1970, marking the UK as one of the most nature-depleted countries globally. BNG aims to reverse this trend by integrating biodiversity improvements into construction projects.

2. Defining “Small Sites”

Small sites are identified as residential developments with one to nine dwellings or those covering less than one hectare. Non-residential and certain industrial sites falling under specific size thresholds also qualify. Despite their size, these projects play a crucial role in the collective effort to enhance biodiversity.

3. The Need for a Competent Assessor

Small developers must appoint a competent person to conduct a Biodiversity Value Assessment using the Small Sites Metric (SSM). This individual doesn’t need to be an ecologist but must possess knowledge and experience in habitat assessment, as defined by British Standard BS 8683:2021.

4. Pathways to Achieve BNG

There are three primary methods for achieving the mandated 10% BNG: direct enhancement within the development site, a combination of on-site and off-site enhancements, or purchasing statutory biodiversity credits. These methods should be applied in a hierarchical order, prioritising direct on-site improvements wherever possible.

5. Incentivising Biodiversity Improvements

Beyond compliance, incorporating BNG measures offers numerous benefits, including increased project appeal and market value. Properties with environmental certifications, for example, have been shown to enjoy significant value premiums. Furthermore, adopting BNG fosters collaboration and innovation, contributing to a more sustainable and appealing construction landscape.

Over to You

For small developers, adapting to BNG requirements is not just about meeting regulatory obligations — it’s an opportunity to contribute positively to the environment and enhance the value and appeal of your projects. As the construction industry evolves, incorporating biodiversity improvements can set your projects apart, ensuring they are future-proof and aligned with broader environmental goals.
