Biodiversity Net Gain

The Environment Act 2021 operates as the UK's new guide for environmental protection. It enforces an approach known as Biodiversity Net Gain (BNG).

Most major developments must now:

  • deliver a minimum 10% biodiversity net gain over and above any existing habitats on site

Types of developments subject to BNG

  • residential developments with 10 or more dwellings, or
  • site areas greater than 0.5 hectares

BNG ensures that biodiversity is left in a better state than before work took place.
