Tenants are being sought for three farms as part of The Crown Estate's ambitious biodiversity and regenerative farming strategy, which is being rolled out across its let land.

Tenders are being invited for Abbey Garth Farm in East Yorkshire as well as Trevethoe House Farm and Boatmere Farm – both in Lincolnshire – with a 6 June deadline.

The successful tenants will take on a unique, 15-year environmental farm business tenancy (eFBT) which has been developed by The Crown Estate alongside the Tenant Farmers Association.

Agreements have been designed with the dual objectives of offering security and sustainability for farmers, while also contributing to The Crown Estate's environmental enhancement goals.

The largest of the three farms is Abbey Garth – a productive, equipped unit six miles north east of Hull.

It comprises 495 acres and includes a 1,000t grain store plus a range of modern and traditional agricultural buildings, which may have potential for diversification. A seven-bedroom farmhouse sits adjacent to Swine Church on the edge of the village.

Soils are mainly grade 3 quality, with some grade 2 on the eastern side of the farm.

"The farm is well suited to producing high-yielding combinable crops," says Andrew Fallows, Partner at national property consultancy Carter Jonas.

"There is also 30 acres of pasture used for livestock grazing, and the land lies predominantly within a ring fence."

Trevethoe House Farm, in Holbeach, Lincolnshire, is ideal for specialist green vegetable and potato production. It includes 358 acres of Grade 1 soils plus 4,000t of box potato cold storage.

Just seven miles away, a tenancy is also on offer for Boatmere Farm at Gedney Marsh. Boatmere has no buildings but includes 81 acres of grade 1 land.

Paul Sedgwick, Deputy Ranger and Managing Director, Windsor and Rural at The Crown Estate, says the groundbreaking agreements are based on traditional tenancy, but with some specific estate-by-estate environmental objectives.

Paul said: "The eFBT agreements are designed to protect and enhance The Crown Estate's rural assets, but were also created with the farmers in mind in a bid to help them adapt to changing supply chain demands thrive and to help safeguard their livelihoods for future generations.

"We have many success stories from our existing tenants who we are working with to adopt these principles around biodiversity and regenerative farming. Uptake has been really positive, and our tenants have the confidence of a 15-year agreement which shows commitment from both sides."

All tenancies commence in October 2025 and the tender submission deadline is at noon on 6 June.
