Paragraph 14 Biodiversity Net GainI1

No development may commence until a scheme (which may comprise of up to 2 parts being one for within England and one for within Wales) securing the provision of BNG of 1% or greater for the priority habitats affected by the authorised development (as calculated using Natural England Biodiversity Metric 3.1, or such other biodiversity metric approved by the relevant planning authority in consultation with the relevant statutory nature consultation body), has been submitted to and approved in writing by the relevant planning authority. The scheme must set out measures to deliver and secure the maintenance for 30 years of the BNG provision.

Where such a scheme is approved under this requirement, the works set out in that scheme must be carried out in accordance with the approved scheme.

The approved scheme shall be maintained in accordance with the scheme of maintenance secured for 30 years of the BNG provision under sub-paragraph (2).
