Land Agent in Oxfordshire: Understanding Biodiversity Net Gain

Oxfordshire’s rural landscape is evolving, and land agents now play an increasingly important role in helping landowners navigate new opportunities. While traditionally centred on farming and estate management, today’s land agents also support clients with conservation, planning, environmental land management, and commercial land use.

One of the most significant emerging opportunities for Oxfordshire landowners is Biodiversity Net Gain (BNG). This offers a long-term income stream and encourages more varied and sustainable land use. Collington Winter Environmental works with developers and landowners across Oxfordshire to assess how many biodiversity units a landowner could sell through habitat banking.

As traditional subsidies continue to reduce, income from BNG is becoming a vital source of revenue. In some cases, land managed for BNG can produce returns of up to £170,000 per hectare over a 30-year period.

Under the Environment Act 2021, major developments in England must deliver at least a 10% biodiversity uplift. BNG ensures that development leaves the natural environment in a measurably better condition.

BNG is measured using Defra’s Biodiversity Metric, which assigns a biodiversity unit value to different habitats. Developers must commission ecological surveys and submit a detailed BNG plan demonstrating how the required uplift will be achieved and maintained. Early collaboration with BNG land agents and ecological consultants is essential to avoid planning delays.

Where development sites in Oxfordshire cannot deliver the 10% uplift onsite, developers can purchase offsite biodiversity units from local landowners who have established habitat banks. These units can be recorded on the BNG Market Register operated by Natural England. With continued development activity across Oxfordshire, demand for offsite units is expected to grow.

A habitat bank is an area of land enhanced and managed specifically for wildlife for a minimum of 30 years. The biodiversity “uplift” generated can be sold to developers needing to compensate for environmental impacts elsewhere.

Land agents increasingly help both developers and landowners take advantage of the opportunities BNG provides. At Collington Winter Environmental, our BNG specialists offer:

Site identification and feasibility – Assessing land for its potential to deliver biodiversity uplift.

Negotiating BNG agreements – Structuring and negotiating long-term habitat management and offsetting contracts.

Valuing biodiversity units – Advising landowners on expected financial returns based on local Oxfordshire demand.

Planning advice – Ensuring proposed habitat creation complies with Natural England guidance and local planning policies.

With combined ecological and planning expertise, our BNG land agents help clients enter the market with clarity and confidence.

Our BNG land agents in Oxfordshire work closely with both landowners and developers, offering expert support to ensure full BNG compliance. Using the latest Defra metrics, we assess habitats and prepare detailed, site-specific BNG plans.

Whether you are a developer seeking BNG support or an Oxfordshire landowner exploring habitat creation as a new income opportunity, our team can guide you through every stage of the process.
