Land Agent in Somerset: Understanding Biodiversity Net Gain

Somerset is known for its varied landscape – from productive arable farmland and rolling pasture to river valleys and protected ecological sites. This diversity creates opportunity, but it also brings complexity. Those managing land in Somerset must balance commercial performance with environmental responsibility, particularly as regulation continues to evolve.

Biodiversity Net Gain (BNG), introduced after the Environment Act 2021, is now a key consideration for most development projects in England. As a result, early ecological advice is more important than ever.

At Collington Winter Environmental, we provide practical, commercially focused ecological advice to help clients make informed decisions while remaining compliant and environmentally responsible.

A land agent plays a central role for farmers, estate owners and rural businesses, ensuring land assets perform effectively while remaining aligned with regulatory requirements and future ambitions. A land agent in Somerset typically assists with:

Farm management and strategic planning – Advising on efficient, resilient and sustainable land use strategies to support long-term productivity and profitability.

Assessing land value and potential – Identifying opportunities beyond traditional agriculture, including environmental schemes, natural capital projects and diversification initiatives.

Buying and selling farmland – Working alongside solicitors and property professionals to facilitate smooth, well-informed transactions.

Diversification planning – Exploring additional income streams such as renewable energy schemes, habitat creation, conservation projects or leisure-based enterprises.

Planning and regulatory guidance – Interpreting how local planning policy and environmental legislation affect rural landholdings and development proposals.

Risk management – Providing practical advice to reduce uncertainty in complex land management or development projects.

Biodiversity Net Gain (BNG) requires most new developments to deliver at least a 10% measurable increase in biodiversity compared with the site’s original condition. This is calculated using DEFRA’s Biodiversity Metric. If a developer cannot achieve the required uplift within their site boundary, they must secure biodiversity units from off-site land.

For landowners in Somerset, this creates opportunity. Areas that may be less productive agriculturally can often be suitable for habitat creation. With ongoing development across the county, demand for off-site biodiversity units is expected to remain steady.

When structured correctly, BNG agreements can provide a reliable, long-term income stream. However, they involve:

• Careful feasibility assessment
• Appropriate legal agreements
• A commitment to manage land for at least 30 years

A habitat bank is land managed specifically to create or enhance wildlife habitats for a minimum of 30 years. These improvements are measured using DEFRA’s Biodiversity Metric and converted into biodiversity units that can be sold to developers.

In Somerset, habitat banks may involve:

• Species-rich grassland restoration
• Wetland creation
• Woodland planting
• Hedgerow enhancement
• Improved field margins

With the right planning, habitat banking can complement existing agricultural operations while generating long-term financial and environmental value. Early ecological assessment is essential to ensure that projected biodiversity gains are realistic and achievable.

Is BNG suitable for all farmland?

Not all land will be appropriate. Soil type, location and existing ecological value all influence suitability. A professional ecological assessment will confirm whether BNG is viable.

How long is the commitment?

Most agreements require land to be managed for at least 30 years. This long-term obligation should be carefully considered.

Can BNG operate alongside farming?

In some cases, yes. Certain habitat types may be compatible with low-intensity grazing or stewardship schemes, but this must be assessed on a site-specific basis.

Is there demand for biodiversity units in Somerset?

Demand depends on local development activity and planning requirements, but in areas experiencing continued growth, demand is generally consistent.
