Agricultural Holdings Act 1986 (AHA) tenancies apply to most farm lettings granted before 1 September 1995. These are the older, more protective form of tenancy, built around a philosophy of long-term security for the tenant. Key features include a statutory right to a rent review every three years, and — crucially — lifetime security of tenure, meaning the tenant generally has the right to remain and request a new tenancy at expiry rather than simply being handed notice to quit.
Farm Business Tenancies (FBTs), introduced under the Agricultural Tenancies Act 1995, apply to lettings granted on or after 1 September 1995 and now cover the great majority of new farm tenancies. FBTs are built around freedom of contract: landlord and tenant are free to agree their own rent review frequency and mechanism rather than falling back on a statutory three-year cycle, and — unlike AHA tenancies — there is no automatic right to a new tenancy when the term expires.
Under an AHA tenancy, either party has a statutory right to trigger a rent review every three years, with rent ultimately assessed against what a reasonably efficient tenant could be expected to pay — a process with its own established methodology and, where agreement can’t be reached, arbitration or third-party determination available.
Under a Farm Business Tenancy, there’s no statutory review cycle at all unless the tenancy agreement itself specifies one. This is exactly why the drafting of an FBT at the outset matters so much — a poorly drafted rent review clause (or the absence of one) can leave both parties without a clear mechanism when the time comes, which tends to generate exactly the kind of dispute that’s expensive to resolve after the fact.
Whether you’re a landlord assessing the value of let agricultural land, a tenant negotiating a rent review, or either party approaching a lease renewal, an accurate valuation needs to account properly for tenancy type. Vacant possession value, tenanted value under an AHA tenancy, and tenanted value under an FBT are three genuinely different figures — reflecting the very different levels of security and flexibility each tenancy type carries for whoever’s occupying the land. Getting this distinction wrong is one of the more common ways rural valuations go astray, particularly in probate, divorce, or succession contexts where the value of tenanted land needs to withstand scrutiny.
Farm tenancy disputes are far cheaper to prevent than to resolve. If you’re a landlord with older AHA tenancies on your land, it’s worth knowing exactly which succession and rent review rights actually apply — not assumed to apply — before a change of tenant forces the question. If you’re a tenant on an FBT approaching the end of your term, it’s worth understanding early that there’s no automatic right to renewal, so any negotiation starts from a realistic position rather than an assumed one.
