Understanding Assured Shorthold Tenancy (AST) Minimum Terms in the UK

An Assured Shorthold Tenancy (AST) is the most common type of residential tenancy agreement in the UK, giving both landlords and tenants specific legal protections. For anyone involved in property rentals, it's crucial to understand the rules around the minimum term of an AST, as this affects both the flexibility and the security of the tenancy agreement.

What is an Assured Shorthold Tenancy (AST)?

An AST is a type of tenancy that allows landlords to let their residential properties to tenants. It provides landlords with the ability to regain possession of the property at the end of the tenancy, provided they follow the correct legal procedures. For tenants, it ensures rights such as the ability to occupy the property for a minimum period and protections against unfair rent increases or eviction during that time.

Minimum Term of an AST

In most cases, there is no legal requirement for a specific minimum term for an AST in England. However, landlords and tenants typically agree on a fixed term, with six months being the traditional minimum duration. This six-month period has become common because it offers stability for tenants and allows landlords to have a reasonable timeframe to establish reliable tenancy. While some agreements might be shorter, these are less common and might involve additional risks for both parties.

It's important to note that while there is no strict legal minimum, most mortgage lenders for buy-to-let properties require a tenancy agreement with a term of at least six months, and often 12 months, as part of the loan conditions. Therefore, landlords should check their mortgage terms before agreeing to shorter tenancies.

Exceptions and Flexibility

Tenancies with a shorter duration than six months are possible but not generally advisable unless there is a compelling reason. For example, some tenants may request a shorter lease if they anticipate only needing temporary housing. In such cases, landlords may accommodate shorter terms, but this often comes with a higher degree of uncertainty and management costs.

Also, a tenancy can become periodic—rolling from month to month—once the fixed term ends if neither party ends the agreement. In these cases, the tenancy continues with the same protections for both landlord and tenant, offering flexibility while maintaining the established terms.

Impact of the Tenant Fees Act 2019

The Tenant Fees Act 2019, which applies to England, restricts landlords from charging tenants for certain services and limits deposits. One impact of this act on ASTs is that it encourages landlords and tenants to establish clear agreements for the fixed term, as tenants are entitled to a refund of any pro-rata rent payments if they vacate the property early under certain conditions. This further reinforces the need for landlords to consider carefully how they structure their AST agreements.

Landlord and Tenant Considerations

For landlords, setting a fixed minimum term protects their income stream and reduces turnover, which can be costly in terms of finding new tenants and preparing the property. For tenants, a fixed term provides stability and clarity, allowing them to plan their housing situation with confidence.

However, flexibility can be important in certain circumstances. If a tenant or landlord anticipates potential changes in their situation, a shorter fixed term followed by a periodic tenancy may be more suitable. Whether opting for a shorter term or a more traditional six or 12-month agreement, both parties should ensure that the tenancy agreement is clear, legally compliant, and fair.
