Land Agent in Cornwall: Understanding Biodiversity Net Gain

Rural land management in Cornwall is evolving rapidly, and the role of land agents has become more important than ever. A land agent is a specialist in rural property who supports the management, sale, and development of land. While the job traditionally centred on agriculture and estate management, modern land agents now also work across conservation, planning, diversification, and environmental projects.

Land agents in Cornwall are particularly valuable in helping farmers and landowners navigate emerging schemes such as Biodiversity Net Gain (BNG), which can deliver long-term income and open up sustainable new uses for rural land.

Collington Winter Environmental works with farmers, landowners, and developers throughout the South West. Our experts calculate how many biodiversity units a site can generate and support landowners in selling those units to developers – an approach often referred to as habitat banking.

For many Cornish farmers, BNG presents an important new income opportunity, especially as traditional subsidies continue to fall. In some cases, land used for habitat banking can generate up to £170,000 per hectare over a 30-year period.

BNG is one of the most significant recent changes affecting rural land. Under the Environment Act 2021, major developments must deliver at least a 10% increase in biodiversity compared with the baseline condition before development.

If a developer cannot achieve this onsite, they must purchase offsite BNG credits. This creates a valuable market for Cornwall’s landowners who can restore or enhance land for wildlife.

BNG sites can be recorded on the BNG Market Register, ensuring transparency and regulation in the sale of biodiversity units.

A habitat bank is a parcel of land – often underused or low-productivity land – managed to create or enhance biodiversity over a 30-year period. The biodiversity uplift is quantified as units, which can then be sold to developers who need to compensate for environmental impacts elsewhere.

Land agents increasingly play a central role in delivering BNG. At Collington Winter Environmental, BNG specialists assist landowners and developers by providing:

Site assessment and feasibility – Identifying land suitable for biodiversity enhancement.

BNG agreement negotiation – Negotiating long-term agreements between landowners and developers.

Biodiversity unit valuation – Advising on market demand, pricing, and potential financial returns.

Planning and compliance – Ensuring BNG plans meet DEFRA metrics, Natural England guidance, and local planning policies.

At Collington Winter Environmental, our team of BNG land agents in Cornwall works with developers and landowners to provide expert advice and ensure BNG compliance. We assess habitats using the latest DEFRA metrics and assemble detailed biodiversity net gain plans for our clients.
