(3) These Regulations extend to England and Wales. ## 2 Biodiversity gain planning condition In these Regulations, “biodiversity gain planning condition” means the condition referred to in paragraph 13 (general condition of planning permission) of Schedule 7A to the Town and Country Planning Act 1990. ## 3 Temporary exemption for small developments (1) The biodiversity gain planning condition does not apply in relation to planning permission for small development where— (a) the application for planning permission for small development was made before 2nd April 2024; or (b) planning permission is granted for small development which has effect before 2nd April 2024. (2) The biodiversity gain planning condition does not apply in relation to a section 73 planning permission where the original planning permission to which the section 73 planning permission relates was exempt by virtue of paragraph (1). (3) In this regulation— “original planning permission to which the section 73 planning permission relates” means a planning permission which is the first in a sequence of two or more planning permissions, where the second and any subsequent planning permissions are section 73 planning permissions; “section 73 planning permission” means planning permission granted on an application made under section 73 of the Town and Country Planning Act 1990 (determination of applications to develop land without compliance with conditions previously attached); “small development” means development which is not major development within the meaning of article 2(1) of the Town and Country Planning (Development Management Procedure) (England) Order 2015. ## 4 De minimis exemption (1) The biodiversity gain planning condition does not apply in relation to planning permission for development which meets the first and second conditions.

(2) In determining whether a development is undertaken solely or mainly for the purpose specified in paragraph (1), no account is to be taken of any facility for the public to access or to use the site for educational or recreational purposes, if that access or use is permitted without the payment of a fee. ## 7A Development no larger than 0.2 hectares (1) The biodiversity gain planning condition does not apply in relation to planning permission for development which meets the first and second conditions. (2) The first condition is that the development does not impact an onsite priority habitat. (3) The second condition is that the development is carried out on a site which has an area no larger than 0.2 hectares. (4) The exemption in paragraph (1) does not apply in relation to planning permission where the application for planning permission was made before 6th August 2026. (5) The exemption in paragraph (1) does not apply in relation to a section 73 planning permission where— (a) the application for the original planning permission to which the section 73 planning permission relates was made before 6th August 2026; or (b) the original planning permission to which the section 73 planning permission relates was granted before 6th August 2026. (6) In this regulation— (a) “original planning permission to which the section 73 planning permission relates” has the same meaning as in regulation 3; (b) “priority habitat” has the same meaning as in regulation 4; (c) “section 73 planning permission” has the same meaning as in regulation 3; (d) a habitat is impacted where the habitat is lost or degraded such that there is a decrease in the biodiversity value of that habitat. ## 7B Temporary development (1) The biodiversity gain planning condition does not apply in relation to planning permission for development which meets the first, second and third conditions. (2) The first condition is that the development does not impact an onsite priority habitat. (3) The second condition is that the whole of the development for which the planning permission is granted consists solely of temporary development. (4) The third condition is that the specified period does not exceed five years. (5) The exemption in paragraph (1) does not apply in relation to planning permission where the application for planning permission was made before 6th August 2026. (6) The exemption in paragraph (1) does not apply in relation to a section 73 planning permission where— (a) the application for the original planning permission to which the section 73 planning permission relates was made before 6th August 2026; or (b) the original planning permission to which the section 73 planning permission relates was granted before 6th August 2026.

That requirement is that the biodiversity value attributable to the development exceeds the pre-development biodiversity value by at least the statutorily specified percentage. Biodiversity value means the value of any habitat or habitat enhancement as calculated in accordance with the biodiversity metric published by the Secretary of State. The exemptions in these Regulations relate to: (a) small developments where an application for planning permission is made or has been granted before April 2024, (b) developments with no impact on priority habitat and where impacts on other habitat fall below specified thresholds, (c) householder applications, (d) the high-speed railway network, (e) off-site gain developments i.e. developments which fulfil the biodiversity net gain requirement arising in relation to another development, and (f) certain self-build and custom build developments. These Regulations also require the Secretary of State to carry out a review of these Regulations at least once in every 5 years.
