Calderdale’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.

Specific BNG Requirements are set out in Policy 2.1 of the BNG SPD (adopted November 2023).

2.1 The Environment Act 2021 amends the Town and Country Planning Act 1990. It sets out that the majority of developments will be legally required to demonstrate a minimum net gain of 10% and secure those gains for a minimum of 30 years.The requirement to demonstrate net gains applies to all habitats within the red line, regardless of whether they are impacted or not. A two-year transition period for this requirement is included in the Act, with provision for secondary legislation to set a date for the requirement to come into force. This is expected to be November 2023.
