Navigating The New Biodiversity Net Gain Landscape
30 January 2024

In a monumental move towards ecological sustainability, significant changes in Biodiversity Net Gain (BNG) legislation are set to come into effect in England on February 12 th 2024. This pivotal date marks a turning point in the way businesses and developers approach environmental considerations, emphasising a commitment to biodiversity preservation and creating positive outcomes for both nature and communities.

Whilst attention is currently focussed on England because of the significant amount of new legislation that will come into force, similar approaches are found elsewhere in the UK. Scottish Government will also seek to quantify developmental impacts on biodiversity, using a metric; although it has decided to deliver this through policy rather than statute. In October 2023, Welsh Government announced that consideration of Net Benefits to Biodiversity and green infrastructure will be a policy requirement for most new development.

What is BNG?

The imminent legal alterations highlight a growing global awareness of the critical need to protect and enhance biodiversity. BNG, a concept gaining traction worldwide, mandates that almost all planning applications in England deliver an increase of at least 10% in biodiversity, either on-site or by off-setting. This initially applies to major developments but BNG rules for small sites (typically less than 1 hectare) will apply from 2 nd April 2024.

BNG requires developers to measure the biodiversity value of a site before and after their project using DEFRA’s Biodiversity Metric 4.0 calculator. This approach ensures the required enhancements needed to achieve the minimum 10% improvement in biodiversity can be identified. If it is not feasible to achieve the necessary biodiversity units within the development area, compensation off-site is needed, through habitat creation and/or enhancement.

Why is BNG Important?

By enforcing Biodiversity Net Gain, the new regulations seek to align economic progress with nature conservation. Companies will need to adopt strategies that actively enhance local ecosystems, fostering resilience and diversity in flora and fauna.

The significance of this legal shift extends beyond mere compliance; it represents a collective commitment to creating sustainable spaces where development and nature coexist, with aspirations for a more ecologically balanced future.

TEP – At The Forefront Of BNG

BNG is in TEP’s DNA! Our very first project in 1997 was to create woodland and grassland habitats on urban brownfield sites. One of them, Kenworthy Woods in south Manchester, has been so successful that it was designated as a statutory Local Nature Reserve in 2023. We have won prestigious awards for BNG, for example our work at Redrow Homes’ 300 house scheme at Heathlands in North Wales secured the Landscape Institute Biodiversity Award.

BNG is a team game and TEP has in-house expertise in ecology, trees, habitat design and implementation, planning, landscape management, costings and mapping. Our Planning team can advise on the process for submitting a planning application, identify planning applications that are exempt from BNG, and clarify the requirements to discharge the statutory BNG condition. Additionally, we can provide guidance on securing legal agreements (such as Section 106).

We conduct biodiversity reviews of land and are proficient in preparing detailed BNG assessments advising on habitat design, enhancement, and management. We are currently supporting a number of clients on a wide range of developments, including residential, commercial and infrastructure, advising on constraints and opportunities, and providing a robust strategy for delivering BNG.

In cases where the necessary biodiversity units cannot be achieved within the development boundary, compensation habitats can be established off-site. We can assist in locating and establishing such off-site habitats. We are helping landowners to optimise the habitat value of their lands for use as off-site compensation, facilitating their registration as a habitat bank.

Compensatory habitats, whether on-site or off-site, necessitate comprehensive management and monitoring for a minimum period of 30 years. TEP is equipped with experienced landscape managers who possess the expertise to implement the necessary management actions for habitat enhancements. This includes the development of detailed landscape management plans and monitoring strategies aligned with the objectives identified by the BNG metric calculator.

We also provide strategic BNG advice, for example need and supply assessments for local authorities and large corporations looking to understand the implications of their long-term development plans. We provide training and a bespoke advisory service for clients needing advice on the many rules surrounding BNG in England, and how to tailor schemes in Wales and Scotland to meet the different policy requirements.

If you have any questions about BNG, or would like to get in touch, please contact tep@tep.uk.com.

On behalf of Cheshire East Council, TEP has secured consent for the expansion of the Environmental Services Hub site. The expansion will facilitate a weekly food waste collection service for every property in the borough, helping Cheshire East Council prepare for a new statutory requirement from central government due to come into force from 2026-2027. To achieve this, we prepared and managed three planning applications: A full application for 84 new employee parking spaces, a bin storage area and a security lodge; A non-material amendment application for the reconfiguration of the existing site layout; and A variation of condition application to increase the limit on vehicle movements. The project began with a pre-application advice request, followed by discussions with the local planning authority to confirm the applications and supporting information required for submission. A key element of the project was the preparation of a planning needs case. This justified the development remaining at the Environmental Services Hub site, rather than a 'preferred site' identified within the council's Waste Plan. The case also identified the benefits of increasing recycling rates and supporting sustainable waste management across the borough. To support the applications, traffic surveys were commissioned and a Transport Statement was prepared, demonstrating that the proposals would have no negative impact on the local highway network. A Transport Note was also produced to establish the number of vehicle movements that should be permitted through the variation of condition application. Air quality and noise assessments were also undertaken to demonstrate that impacts would be limited and acceptable.

Plans for Brookleigh Primary School have received unanimous planning approval at Mid Sussex District Council's District Planning Committee on 28th May 2026. The new school, located to the east of Isaacs Lane, will provide 420 student places, alongside a 52-place nursery and a 16-place Special Support Centre. As a two-form entry school, it will support two classes per year group. This marks a proud first for Homes England as master developer, directly delivering new school places for the Brookleigh community. TEP worked in partnership with the wider project team, including CampbellReith, sixfootstudio, Fabrik, FLOH and Stace, to help bring the proposals forward. Supporting the Delivery of a New School TEP's Planning team co-ordinated the preparation of the reserved matters application, including pre-application discussions and community consultation, while our Ecology team completed site surveys and advised on Biodiversity Net Gain (BNG). A key part of our role was ensuring that local people and stakeholders had opportunities to engage with the proposals as they developed. In preparation for the application submission, we organised public consultation events and prepared consultation materials explaining the scheme, masterplan, access strategy, landscaping, and the proposed layout and appearance of the school. Two public exhibitions were held at an accessible venue close to the site, providing an opportunity for the local community to discuss the proposals, ask questions and share feedback. We also organised an information leaflet drop to approximately 4,000 homes and established an online consultation portal to enable people to engage digitally. The feedback received was largely positive, reflecting both the demand for new school places and the work undertaken by the project team to develop a modern, sustainable design for the Brookleigh community.

We have been proud to support the regeneration of the Grade II Listed Earlestown Town Hall, one of the most historically and visually significant buildings in the town centre. Dating from the late 19th century, the Flemish-inspired civic building occupies a commanding position within Earlestown and has long served as a local landmark and community venue. Over the years, the Town Hall has played host to generations of local events and performances, including an appearance by The Beatles during the early years of their rise to fame. Commissioned by ECF, we provided heritage and archaeology consultancy services to support the redevelopment and restoration of the building as part of wider regeneration ambitions for Earlestown town centre. Working as part of a multidisciplinary team, we offered heritage advice throughout the pre-application stage, helping to shape proposals that would be sympathetic to the building’s historic character while enabling it to meet modern community needs.
