Biodiversity Net Gain (BNG)

To help applicants deliver biodiversity net gain as required under Policy S61 and the national requirement, a guidance note has been prepared and is available below. This will be kept under review and will be updated upon further updates to legislation.

Biodiversity Net Gain guidance notes


Biodiversity Net Gain - Validation requirements

BNG is now a national mandatory requirement for major and minor applications. 

Where development would be subject to the general biodiversity gain condition, the application must be accompanied by minimum information set out in Article 7A of the Town and Country Planning Act 1990

The following is the mandatory minimum information required (some of this information can be provided using the Central Lincolnshire Biodiversity Gain Statement):

  • Confirmation that the applicant believes that planning permission, if granted, the development would be subject to the biodiversity gain condition
  • The pre-development biodiversity value(s), either on the date of application or earlier proposed date (as appropriate)
  • Where the applicant proposes to use an earlier date, this proposed earlier date and the reasons for proposing that date
  • The completed metric calculation tool showing the calculations of the pre-development biodiversity value of the onsite habitat on the date of application (or proposed earlier date) including the publication date of the biodiversity metric used to calculate that value;
  • A statement whether activities have been carried out prior to the date of application (or earlier proposed date), that result in loss of onsite biodiversity value (‘degradation’), and where they have:
  1. A statement to the effect that these activities have been carried out
  2. The date immediately before these activities were carried out
  3. The pre-development biodiversity value of the onsite habitat on this date
  4. The completed metric calculation tool showing the calculations, and any available supporting evidence of this

Or;

  • Where applicants consider that the development would not be subject to the general biodiversity gain condition, a statement to set out what exemption(s) or transitional provision(s) apply to the development.

In addition to these minimum requirements, further information may be required to assist the consideration of BNG as part of the planning application, to enable the Local Planning Authority to consider whether the general condition is capable of being successfully discharged following approval. For example, where there are considerations around significant onsite biodiversity enhancements or use of offsite biodiversity units.


Exemptions

Planning applications that are exempt from requiring mandatory BNG include (but are not limited to):

  • S73 applications for planning applications approved prior to BNG becoming mandatory
  • Householder applications
  • Permitted development
  • De-minimis applications – those that have an impact on an area of habitat below 25m2 (such as 5m x 5m) and below 5m in length for linear habitats, and do not affect priority habitat at all.
