Portsmouth City’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.

Portsmouth City is part of the Hampshire Local Nature Recovery Strategy. Information can be foundhere.

Specific BNG requirements are set out in policy 5.1.23 of the Local Plan (draft September 2021).

Net gains in biodiversity will need to be quantifiable and capable of being secured by planning condition. Contributions to biodiversity enhancement may be sought where sufficient net gain cannot be delivered on-site. The council will be preparing a shortlist of suitable projects, in conjunction with key stakeholders, for biodiversity creation and/or enhancement for which off-site contributions could be made to ensure biodiversity net gains are primarily delivered within the city.

A new Local Plan is currently in consultation. See also the BNG Page. For further information, see the Portsmouth Greening Strategy and Delivery Plan (adopted June 27, 2023).
