Bromley’s BNG level is set at 10%.

The NPPF states: "applicants are encouraged to consider biodiversity net gain early in the development process and factor it into site selection and design. Where appropriate, they should discuss the biodiversity net gain requirements for their development upfront with the relevant local planning authority utilising any pre-application advice services offered by them. This could help establish whether development proposals would be subject to biodiversity net gain and, if they are, enable feedback on the proposed strategy for achieving the biodiversity gain objective and consideration of the Biodiversity Gain Hierarchy to inform the design of the proposals"

Please note, If you work for the LPA and wish to add additional information, please inform the Joe's Blooms team here.

Bromley is part of the Greater London Local Nature Recovery Strategy. Information can be foundhere.

Specific BNG requirements are set out in Policy G6 of the Biodiversity Plan (adopted 2021).

Sites of Importance for Nature Conservation (SINCs) should be protected and planned for by Local Authorities. Where harm is unavoidable, and where the benefits of the development proposal clearly outweigh the impacts on biodiversity, the following mitigation hierarchy should be applied to minimise development impacts: 1) avoid damaging the significant ecological features of the site 2) minimise the overall spatial impact and mitigate it by improving the quality or management of the rest of the site 3) deliver off-site compensation of better biodiversity value. Development proposals should manage impacts on biodiversity and aim to secure net biodiversity gain. This should be informed by the best available ecological information and addressed from the start of the development process. Proposals which reduce deficiencies in access to nature should be considered positively.
