What does security of tenure mean?

25th March 2026 · Commercial Property

Businesses often invest significant time and money into the premises they occupy.

Fitting out a space and establishing a recognisable location for customers can make commercial property a central part of day-to-day operations and long-term growth. Given this level of investment, the terms that govern a business’s right to remain in that space carry real importance. One key legal concept that shapes this is security of tenure.

In this guide, we explain how security of tenure operates in commercial property, the circumstances in which leases may be protected by the statutory framework, and why both landlords and tenants need to consider these issues carefully during lease negotiations.

What security of tenure means in a legal context

In legal terms, security of tenure refers to a tenant’s right to continue occupying a property after the contractual term of their lease has ended. For businesses operating from commercial premises, this protection can be particularly important, as it helps ensure that a landlord cannot simply require the tenant to leave when the lease expires.

Where security of tenure applies, a tenant typically has the right to remain in occupation of the premises and to request the grant of a new lease. In practice, this means the landlord must follow a specific legal process if they wish to regain possession of the property, rather than automatically taking it back at the end of the agreed term.

How the Landlord and Tenant Act 1954 created security of tenure

Security of tenure for most commercial tenants in England and Wales comes from Part II of the Landlord and Tenant Act 1954. This legislation sets the starting legal position for many business leases and determines when tenants are entitled to statutory protection.

In practice, the Act assumes that qualifying tenants will benefit from security of tenure unless the parties take formal steps to remove those rights before the lease begins. As a result, protection often applies automatically rather than needing to be specifically written into the agreement.

For the statutory protection to apply, certain conditions must usually be satisfied. These include:

  • The premises are occupied for the purposes of a business
  • The arrangement is legally a tenancy, not merely a licence to occupy
  • The tenant is in genuine occupation of the premises
  • The tenancy runs for a period exceeding six months

What it means to be inside or outside the Act

When negotiating a commercial lease, one of the most important decisions is whether the tenancy will be protected by the Landlord and Tenant Act 1954 or excluded from it. This is often described as a lease being either ‘inside’ or ‘outside’ the Act.

Where a lease is inside the Act, the landlord cannot simply recover possession once the lease expires. They must follow the formal legal procedures set out in the legislation if they wish to bring the tenancy to an end.

By contrast, a lease that has been contracted out of the Act does not carry these statutory protections. The tenant does not have an automatic right to remain in the property or to request a new lease. Instead, the arrangement ends when the agreed lease term expires, unless the parties choose to negotiate a new agreement.

Whether a lease will be inside or outside the Act is usually decided before the lease is granted, often during the early negotiation stage. This is commonly recorded in the Heads of Terms, which outline the key commercial points of the deal before the formal lease is drafted.

Why security of tenure matters for tenants

Here are a few of the key benefits that security of tenure can offer to business tenants:

Business stability and long-term planning

One of the main advantages of security of tenure is the stability it provides. When a tenant has the right to remain in occupation or request a new lease, it becomes easier to plan ahead, develop business strategies, and make long-term operational decisions without the constant risk of losing the premises.

Greater confidence to invest in premises

Tenants often invest significant time and money into adapting premises to suit their needs. This might include interior fit-outs, refurbishments, or specialist installations. Where renewal rights exist, tenants may feel more comfortable making these improvements because there is a greater likelihood of remaining in the property for longer.

Protecting business goodwill

Business premises often become closely associated with a company’s brand, reputation, and customer base. As the business becomes established, it may build significant goodwill connected to where it operates.

Security of tenure helps protect that goodwill by reducing the risk of a tenant being required to leave at the end of the lease term. Without the right to renew, a tenant could be forced to relocate, potentially losing the advantages of the trading location and the customer relationships developed there.

The ability to negotiate rather than relocate

Security of tenure also provides an opportunity to negotiate a renewal with the landlord instead of simply vacating the property when the lease term ends. This can give tenants a stronger position when discussing future rent, lease length, or other commercial terms.

Why some landlords choose to contract out of security of tenure

While security of tenure can provide valuable protection for tenants, some landlords prefer to grant leases that are contracted out of the statutory regime. Here’s why:

Avoiding reliance on statutory grounds

If a lease is protected, landlords who wish to prevent renewal must rely on specific legal grounds set out in legislation. Contracting out removes this requirement, meaning the landlord can regain vacant possession without needing to justify the decision through the statutory framework.

Supporting future property plans

In many cases, landlords contract out of security of tenure because they anticipate changes to the property. This approach can be particularly useful where the landlord may wish to:

  • Redevelop the premises
  • Carry out substantial refurbishment works
  • Change the use of the building
  • Cell the property with vacant possession

Maintaining control over long-term property strategy

Ultimately, contracting out can allow landlords to retain greater control over how their property is managed over time. It provides the freedom to reassess the use of the premises at the end of each lease term and align decisions with broader investment or development objectives.

The legal process for contracting out of security of tenure

Removing security of tenure from a commercial lease is not something that can be done informally. The law requires a specific statutory procedure to be followed before the lease is granted.

Landlords must take clear and documented steps if they want a lease to fall outside the statutory protection. This includes:

The warning notice

The first step is for the landlord to serve a Warning Notice on the prospective tenant. This document explains that the lease will be contracted out of the statutory regime and that the tenant will not have the right to remain in the premises or request a new lease once the term ends.

The tenant’s declaration

After receiving the warning notice, the tenant must formally confirm that they understand and accept the position. This is done by signing either:

  • A simple declaration, which confirms the tenant has received and understood the warning notice
  • A statutory declaration, which must be sworn before an independent solicitor or commissioner for oaths where the lease is being completed at short notice.

If the statutory process is not followed correctly, the lease may still be treated as protected by security of tenure. For this reason, both landlords and tenants should seek specialist legal advice when negotiating and drafting commercial leases to ensure the correct procedure is followed and the intended legal position is properly documented.

When a landlord can refuse a lease renewal

Landlords can oppose the grant of a new tenancy in certain circumstances, but they must rely on specific statutory grounds set out in legislation.

Some of these grounds relate to the tenant’s conduct during the lease. For example, a landlord may object to renewal if the tenant has persistently paid rent late or has committed a substantial breach of their repair obligations under the lease.

Other grounds focus on the landlord’s future intentions for the property rather than any wrongdoing by the tenant. For instance, a landlord may refuse renewal if they intend to demolish or substantially reconstruct the premises, or if they plan to occupy the property themselves for business purposes.

These latter reasons are often referred to as ‘no-fault’ grounds, as the tenant may have complied fully with the lease but still be required to leave because of the landlord’s plans.

Where a tenant is required to vacate the property due to certain no-fault grounds, they may be entitled to statutory compensation. The purpose of this compensation is to recognise the disruption caused to a business that must relocate despite not having breached the terms of the lease.
