Assigning a commercial lease transfers it from one tenant to another, but it is rarely a simple handover. Here is a practical guide to the process and its legal implications.
Assigning a commercial lease means transferring the whole of the tenant's interest in the property to another party for the remainder of the term. Businesses commonly assign a lease when they outgrow premises, relocate, sell their business, or need to exit a property before the end of the term.
Unlike a subletting, where the original tenant remains responsible and grants a sub-lease to an undertenant, an assignment involves a complete handover of the tenant's interest. However, this does not always mean the outgoing tenant walks away entirely — most landlords will require an Authorised Guarantee Agreement (AGA), keeping the outgoing tenant on the hook if the new tenant defaults.
The process is governed both by the lease itself and by the Landlord and Tenant Act 1954 and the Landlord and Tenant (Covenants) Act 1995. Speak to our lease assignment solicitors before you commit.
An assignment is the legal process by which a tenant (the assignor) transfers their entire leasehold interest to another person or business (the assignee). From the date of assignment, the assignee steps into the shoes of the original tenant and becomes responsible for complying with the lease, including paying rent and performing the tenant covenants.
An assignment should be distinguished from a subletting. In a subletting, the original tenant remains the tenant under the headlease and simply grants a sub-lease to a third party. Assignments and sublettings have very different legal and commercial consequences.
The exact steps will vary depending on the lease and the parties involved, but a typical assignment follows this sequence:
Under the Landlord and Tenant (Covenants) Act 1995, a landlord can, in most cases, require the outgoing tenant to guarantee the performance of the incoming tenant's obligations by entering into an Authorised Guarantee Agreement (AGA). This means that if the assignee fails to pay rent or breaches the lease, the landlord can pursue the outgoing tenant.
An AGA is a significant ongoing liability that many tenants overlook. It generally lasts until the assignee lawfully assigns the lease onwards. Understanding the scope of any AGA before you assign is therefore essential.
Before committing to an assignment, confirm whether the lease permits assignment, what consent is required, whether an AGA will be demanded, and what residual liabilities you may retain as the outgoing tenant.

Assigning a commercial lease can be an effective way to exit premises or transfer a business, but it is not a simple matter of handing over the keys. From landlord consent to the potential for an Authorised Guarantee Agreement, the process carries legal and financial implications that deserve careful attention.
The key is to understand your obligations before you begin. A well-managed assignment protects your business, minimises ongoing liability, and helps avoid costly disputes down the line.
