Biodiversity Net Gain

Mandatory biodiversity net gain as set out in the Environment Act 2021 requires all new developments (unless exempt) under the Town and Country Planning Act 1990 to deliver at least 10% biodiversity net gain from 12 February 2024, with small sites requiring BNG from 2 April 2024.

The first step in delivering BNG is to undertake a BNG Feasibility Assessment, normally as part of a Preliminary Ecological Appraisal. As development plans progress, including measures to deliver BNG, a full BNG Assessment can be undertaken.
