Introduction to Subletting and Assignment
Subletting and assignment are two important concepts in UK renting law. Subletting happens when a tenant rents out all or part of their home to someone else, creating a new tenancy agreement between the tenant and the subtenant. Assignment, on the other hand, is when a tenant legally transfers their tenancy to another person, who then takes over the rights and responsibilities of the original agreement.
Tenants might consider subletting if they need to move temporarily but want to keep their tenancy, or if they wish to share costs by renting out a spare room. Assignment is often used when tenants want to leave permanently but have found someone else to take over their lease.
Understanding the legal rules around subletting and assignment is crucial. Failing to follow the correct process can lead to eviction or other legal issues. The rules can be complex, and many tenancies require the landlord’s written permission before subletting or assigning. For a full explanation of the laws that apply, including the responsibilities of both tenants and landlords, see the official guidance in the Housing Act 1985.
If you are new to renting or want to know more about your rights and responsibilities as a tenant or landlord, you may find it helpful to read our overview of Renting Law in the UK. You can also compare subletting with the process of renting out your own property to understand the different legal requirements involved.
What Is Subletting?
Subletting is when a tenant rents out all or part of their home to another person, known as a subtenant. If you sublet part of your property, you continue living there but share the space with someone else. This is common in shared flats or houses. If you sublet the whole property, you move out and let someone else live there instead, while your name remains on the original tenancy agreement.
Tenants may consider subletting for various reasons. Some want help with rent by letting out a spare room. Others might need to be away for work or travel and want to keep their tenancy while they’re gone.
Before subletting, it’s important to check your tenancy agreement. Most agreements require you to get your landlord’s permission first. Subletting without consent can lead to eviction or legal problems. You should also be aware of your responsibilities as the main tenant, as you remain legally responsible for the property and the rent.

What Is Assignment of a Tenancy?
When you assign a tenancy, you transfer your entire legal interest in the property to another person. This means the new tenant takes over all your rights and responsibilities under the tenancy agreement. From the date of assignment, you are no longer liable for rent or any other obligations.
Assignment is different from subletting. With subletting, you remain the main tenant and continue to be responsible to your landlord, even if someone else lives in the property. Assignment, on the other hand, is a complete handover of your tenancy to someone else.
Assignment might be possible if you need to move out before your tenancy ends, or if your circumstances change. It can be beneficial if you want to avoid breaking your contract early or paying rent for a property you no longer live in.
In most cases, you need your landlord’s written consent to assign your tenancy. The rules around assignment are often set out in your tenancy agreement and are guided by laws such as the Housing Act 1988.

Getting Landlord Permission and Understanding Your Tenancy Agreement
Before you think about subletting your rental property or assigning your tenancy to someone else, it’s important to understand your legal responsibilities. In most cases, you will need your landlord’s permission before you can sublet or assign your tenancy. This is because landlords have the right to know who is living in their property and to control who takes on the tenancy.
Most tenancy agreements include specific clauses about subletting and assignment. These clauses set out whether you are allowed to sublet, and if so, under what conditions. Some agreements may ban subletting altogether, while others may allow it with written consent from the landlord. Always read your tenancy agreement carefully to check what is permitted. For more information on what to look for in your tenancy agreement, see our guide to Tenancy Agreements: Legal Overview for Renters and Landlords.
If you are considering subletting, it’s crucial to get your landlord’s permission in writing. This helps avoid misunderstandings or disputes later on. Verbal agreements can be difficult to prove if there is a disagreement.
To understand your rights and responsibilities around subletting, you can also refer to the official government guidance on tenancy agreements at GOV.UK. This resource explains the legal framework for private renting, including the importance of permissions and the consequences of breaching your agreement.
Rights and Responsibilities When Subletting or Assigning
When you sublet your rental property, you take on extra responsibilities. As the original tenant, you must make sure your subtenant follows all the rules set out in your tenancy agreement. This includes things like not causing damage, avoiding antisocial behaviour, and paying rent on time.
Importantly, even if someone else is living in the property, you remain responsible to your landlord. If your subtenant causes problems or fails to pay rent, you are still liable. You must continue to pay the full rent to your landlord and ensure the property stays in good condition.
It’s also vital to inform your landlord about any changes in who is living at the property. Failing to do so could lead to breaches of your tenancy agreement. To understand what your agreement covers, see the key things every UK tenancy agreement should include.
If you assign your tenancy to someone else, all your rights and responsibilities are transferred to the new tenant. After assignment, you are no longer liable for the rent or the property’s condition.

Risks and Legal Issues with Illegal Subletting
Illegal subletting happens when a tenant rents out all or part of their home without the landlord’s permission, or in a way that breaks the terms of their tenancy agreement. This is a serious issue and can lead to significant problems for both tenants and landlords.
For tenants, the main risks include being evicted or facing legal action. In some cases, especially in social housing, unauthorised subletting can even result in criminal charges. You can find more information about these penalties on Shelter Legal England – Penalties for unauthorised subletting of social housing – Shelter England.
Landlords who suspect illegal subletting need to identify and prove that it has taken place. This can be challenging, but there are clear steps landlords can follow to gather evidence and take action. For a detailed guide on how to approach this process, including what evidence is needed and how to proceed, see our page on How to Prove Illegal Subletting as a UK Landlord.
If illegal subletting is confirmed, landlords may need to start the eviction process. To understand the legal steps involved, read our advice on How to Legally Evict a Tenant as a Private Landlord in the UK.
Ending Your Tenancy and Subletting
Subletting or assigning your tenancy can make ending your agreement more complex. If you have sublet your property or assigned your tenancy to someone else, you remain responsible for following the correct process to end the tenancy. It’s important to check your tenancy agreement and make sure you understand your responsibilities, as both you and your subtenant or assignee may be affected.
Before ending your tenancy, always communicate clearly with your landlord. Let them know your plans and confirm any steps you need to take, such as giving notice or arranging for your subtenant to leave. Ending a tenancy incorrectly could leave you liable for unpaid rent or other issues.
For more on the correct process, see our guide to Ending Your Tenancy: Legal Overview.
