So, what is BNG and who will it apply to? BNG is a new law under the Environment Act 2021 and Town and Country Planning Act 1990. It is a new way of creating and improving natural habitats and ensuring that a development will have a measurably positive impact (net gain) on biodiversity compared to what was there before. Developers must enhance the land they plan to develop on by at least 10%, resulting in more or better-quality habitats. It will apply to major developments from 12th February 2024 and to small sites from 2nd April 2024. This will apply to developers, local planning authorities, landowners, and land managers, with relevant guidance available.
