Improving the implementation of Biodiversity Net Gain for minor, medium and brownfield development

Closes 24 Jul 2025

Opened 28 May 2025

Overview

We want to know what you think about the implementation of biodiversity net gain (BNG) for minor, medium and brownfield development. 

BNG is a way of creating and improving natural habitats. BNG makes sure development has a measurably positive impact (‘net gain’) on biodiversity, compared to what was there before development.    

This consultation includes options around extending exemptions, simplifying the small sites metric and increasing ease of access to the off-site market. It also addresses specific challenges for brownfield developments. 

The government is committed to encouraging economic growth through new development, while also supporting nature recovery. We think amending BNG to more efficiently embed nature-positive approaches within the planning system will help achieve this mission.  

The consultation document is attached below. We would recommend reading the whole consultation document and referring to the annex to ensure you consider all options before responding.
