Biodiversity Net Gain Reading: Understanding BNG

Biodiversity Net Gain Reading

Biodiversity net gain (BNG) is a planning system whereby developers consider the environmental impact a project will have in terms of biodiversity. It aims to ensure that biodiversity is left in a better state than before the development was completed for at least 30 years. This is done by avoiding loss of biodiversity and retaining natural habitats and ecological features.

Biodiversity Net Gain is now being requested more frequently to inform planning applications. The aim is to demonstrate how the proposed development will be of benefit to biodiversity in a measurable manner. 

Following the passing of the Environment Bill, mandatory biodiversity gain for developments in Reading will be introduced through the forthcoming Environment Act in January 2024. Following this, any development will be halted if it fails to meet the requirements. However, BNG is already required by the National Planning Policy Framework.

Due to relevant national legislation, biodiversity net gain is soon to become mandatory in Reading. The Government is now requesting biodiversity net gain and nature recovery to determine planning applications for planning permission.

Biodiversity Net Gain Principles


There are ten crucial good practice principles of biodiversity net gain. These should help to achieve BNG if they are followed accordingly. The mandatory biodiversity net gain principles include the following:

  • Utilise the mitigation hierarchy to minimise the impact on biodiversity
  • Eliminate any negative impacts on biodiversity
  • Communicate each BNG outcome with complete transparency
  • Cover all areas of sustainability, including societal and economic factors
  • Involve any pre-development and post-development stakeholders in creating mandatory net gain solutions
  • Focus on producing long-term natural net benefit for biodiversity. This will ensure a development leaves biodiversity in a better state than it was before
  • Understand the variable factors and potential risks in order to achieve biodiversity and deliver net gain
  • Offer nature conservation that exceeds the stated BNG requirements
  • Determine a suitable method in order to secure measurable biodiversity net gains
  • Ensure the best possible results from biodiversity net gain

Biodiversity Net Gain Metric

The biodiversity metric serves as a tool to gauge how a development or alteration in land management will impact the biodiversity value of a site. This includes activities like constructing houses, establishing woodlands, or cultivating wildflower meadows.

This metric enables you to:

  • Evaluate the biodiversity unit worth of a specific land area.
  • Provide a consistent means of showcasing biodiversity gains or losses.
  • Quantify and acknowledge direct effects on biodiversity.
  • Compare different proposals for a site, whether they involve on-site or off-site habitat creation or enhancement.

It aids in the process of designing, planning, and making informed land management decisions that prioritise biodiversity. The metric computes values in terms of ‘biodiversity units’, which are determined by considering factors like habitat size, quality, and location.

Biodiversity Credits

Most local planning authorities in Reading will want developers to ensure that BNG is achieved on-site. In some circumstances, this cannot be achieved, and it is simply not possible. However, this does not mean that the local planning authorities will automatically refuse a planning application.

Instead, the local planning authority may grant planning consent if developers are able to deliver sufficient biodiversity net gain using offsite biodiversity habitat enhancement.

Developers may be given the option of purchasing biodiversity credits through funding schemes that will generate the equivalent number of units in other areas.

The biodiversity net gain credits purchased will then be invested into habitat creation and enhancement.

Natural England is currently supporting the design of the credits scheme by developing payment structures and a BNG credit investment pipeline to fund habitat provision.
