Biodiversity Net Gain Plans in London

Despite a two-year transition period, a large percentage of local planning authorities will already be following the rules of biodiversity net gain and expect a 10% increase in the majority of projects. To assist developers to meet the mandate, ecologists are able to develop bespoke BNG plans for projects in the London region.

Environmental Condition of Greater London and the City of London

The current state of biodiversity in the London region is detailed in the executive summary of the London Environment Strategy. Despite admitting that the environment has been improving in many ways over recent times, the strategy makes several strong claims. For instance, it states that carbon dioxide emissions are too high, nearly half of residents don’t have access to open green areas, the demand for fresh water is outweighing the rate of supply, sections of the city are reaching full capacity of the available electricity infrastructure, and poor air pollution has been the cause of thousands of early deaths in residents.

By the year 2050, the City of London alone is predicted to be occupied by over 11 million residents, and according to the London Environment Strategy, the environmental issues listed above will only worsen if effective changes aren’t made soon. Along with multiple pledges made in the strategy, biodiversity net gain (BNG) is set to greatly improve the condition of London and the rest of England. Introduced into UK law as part of the Environment Act in 2021, BNG enforces an increase of ecological assets equating to a minimum of 10% following the completion of the majority of development projects, including a significant portion of planning projects in the City of London and Greater London.

Councils Across the London Region

All of England will be affected by the biodiversity net gain planning policy, with only a few specific exemptions. While you may be under the impression that every development in the London region will be under the jurisdiction of one all-encompassing local authority, Greater London is in fact split into 32 borough councils, and a separate local authority oversees the City of London.

For support ensuring you correspond with the correct local council for your London development, all local authorities in the region are listed below:

The Concept of Biodiversity Net Gain

Excluding only a handful of exceptions, the biodiversity net gain planning requirement affects all development projects in England. It centres on the concept of increasing ecological value on a site by a minimum of 10%. For it to work, a measurement is taken beforehand and a post-development measurement is predicted using the plans of the project. Changes that are needed will then be determined based on the gap between the two measurements and what needs to be done to reach a minimum net gain of 10%.

Since November 2021, the biodiversity net gain policy has been undergoing a two-year transition period, meaning that developers and local authorities alike are given an opportunity to adjust to it before it becomes a mandatory requirement. That said, in preparation for national adherence in 2023, many planning departments within local councils have instantly began to enforce BNG. As a result, developers are advised to follow the rules of the policy as it may be the case that their local planning authority treats it as a mandatory expectation ahead of time.

Satisfying the BNG Policy

Along with local councils and developers, experts in ecology have also had to develop a quick and effective understanding of biodiversity net gain. Depending on your choice of ecological consultancy, you may find levels of expertise in certain areas, and BNG has become yet another consideration. With it standing as an important component in the majority of current and future planning projects, it is crucial that you hire an ecological team that are extensively knowledgeable about biodiversity net gain and the requirements of your local council.

Through maintaining a focus on biodiversity net gain since the concept’s infancy, our ecologists are equipped for offering impactful guidance and insight that will ensure your development meets or exceeds the BNG policy. Using the recommendations of an ecological consultant during an assessment on a plot of land, effective next steps can be developed within a BNG plan that will guarantee the development is carried out in a way that meets the requirements of the policy. It will also contribute to a local planning authority when it comes to granting or denying applications for planning permission on the site.

Working the additional consideration surrounding biodiversity net gain into your development project will eliminate the potentially costly delays that could arise from disregarding the policy. Refusal to do this would be particularly risky if you chose to ignore BNG under the jurisdiction of a local council that enforce it prior to completion of the two-year transition.

Following an assessment on a development site, our biodiversity net gain plans will cover every ecological feature present, including obstacles that could cause harm to biodiversity value, worthwhile components that need to be kept to retain existing biodiversity value, and factors that could be added or enhanced to increase biodiversity value.
