Biodiversity: Property Development

The question

To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment she has made of the potential impact of increasing the biodiversity net gain de minimis threshold from 0.1 hectares to 0.5 hectares on nature recovery.

Answered by Mary Creagh

The Government recently consulted on options to improve the way Biodiversity Net Gain works for small, medium and brownfield development. This included potential changes to the de minimis exemption threshold, which currently sits at 25 square metres. Since then, the Government has announced its intention to introduce a new area-based exemption set at 0.2 hectares to reduce costs for smaller development while maintaining nature recovery at scale. A full consultation response and impact assessment will be published in due course.
