Biodiversity Net Gain Assessment in Somerset

At Invasive Weed we specialise in biodiversity net gain (BNG) assessments in Somerset to help developers, landowners, and planners comply with the UK Environment Act 2021, which mandates a 10% increase in biodiversity for most developments.

A BNG assessment ensures that construction projects not only preserve but also enhance natural habitats, making them more sustainable.

Many local planning authorities now require a BNG strategy as part of planning applications in Somerset, making it an essential component of infrastructure, commercial, and residential developments.

Our licensed expert ecologists do baseline habitat surveys, biodiversity impact calculations, and mitigation and enhancement strategies to help projects meet all regulatory requirements.

What Is the Biodiversity Net Gain Assessment Process in Somerset?

The biodiversity net gain (BNG) assessment process begins with the initial site survey, where ecologists conduct a habitat assessment to establish baseline ecological conditions. In the next step, the DEFRA 4.0 biodiversity metric tool is used to figure out the existing biodiversity value in Somerset and biodiversity unit scores.

This is followed by the impact assessment in Somerset, which evaluates how the proposed development will affect biodiversity, identifying areas where habitat loss or degradation may occur.

Based on these results, the BNG strategy development in Somerset phase plans ways to improve habitats, fix up damaged areas, or make up for lost biodiversity in order to reach the goal of 10% net biodiversity gain.

Finally, the process concludes with the submission of the BNG report, which includes all required documentation for planning applications and regulatory approval.

What Does a Biodiversity Net Gain Assessment Include in Somerset?

A biodiversity net gain assessment in Somerset includes habitat evaluation, impact calculation, mitigation planning, and compliance reporting.

Biodiversity net gain surveys in Somerset include:

• Baseline habitat survey in Somerset – Ecologists assess the existing ecological value of the site using the DEFRA biodiversity metric tool.

• Habitat classification & mapping in Somerset – Categorization of different habitat types and their ecological importance.

• Biodiversity impact calculation in Somerset – Measurement of potential biodiversity loss due to development and calculation of required biodiversity gain.

• Mitigation & enhancement strategies in Somerset – Development of habitat creation, restoration, or off-site compensation measures to meet BNG requirements.

• BNG report & planning recommendations in Somerset – Summary of findings, ensuring project compliance with local planning policies and national biodiversity regulations.

How Much Does a Biodiversity Net Gain Assessment Cost in Somerset?

The cost of a biodiversity net gain assessment ranges from £1,500 to £7,500, with additional expenses for habitat offsetting, biodiversity credits, and mitigation plans in Somerset.

For small-scale developments, a BNG assessment typically costs between £1,500 and £3,000, while medium- to large-scale projects in Somerset may range from £3,500 to £7,500, depending on the level of ecological detail required.

Additional costs may include habitat offsetting in Somerset (£5,000–£25,000 per hectare), biodiversity credits (£10,000+ per credit), and mitigation plans (£2,000–£5,000).

Is a Permit Required for a Biodiversity Net Gain Assessment in Somerset?

A biodiversity net gain (BNG) assessment in Somerset itself does not require a permit, but achieving biodiversity net gain compliance is now a legal requirement for most developments under the UK planning system.

Local authorities require a BNG strategy as part of planning applications, and failure to comply could lead to project delays or rejection. In some cases, if protected species or habitats are identified during the assessment, additional mitigation licenses may be required from Natural England in Somerset or relevant regulatory bodies.

Our team in Somerset assists in securing permits, navigating planning requirements, and ensuring full BNG compliance.

How Long Does a Biodiversity Net Gain Assessment Take in Somerset?

A biodiversity net gain (BNG) assessment takes 2–4 weeks in Somerset for small projects and 6–8 weeks for larger or complex sites, depending on survey requirements and seasonality.

A basic BNG assessment in Somerset for a small development can typically be completed within two to four weeks, while larger or more complex projects may take six to eight weeks in Somerset due to detailed habitat evaluations and mitigation planning.

Seasonality also affects BNG assessments in Somerset, as certain habitat surveys must be conducted during specific times of the year.

What Are the Environmental Considerations in a Biodiversity Net Gain Assessment in Somerset?

A biodiversity net gain (BNG) assessment of environmental strategies includes habitat creation (wildflower meadows, wetlands, and woodlands), biodiversity corridors, rewilding projects, and off-site biodiversity credits in Somerset.

We work with developers to integrate BNG measures in Somerset into their projects, ensuring they align with sustainability goals and UK biodiversity laws.
