If you have discovered that a property has been sublet without permission and believe the sublet agreement is invalid, it is natural to feel uncertain about how to regain possession lawfully. Many landlords are unsure whether to use a Section 21 or Section 8 notice, particularly where the occupiers are not authorised tenants.
Understanding the correct eviction route under UK law is essential. Using the wrong process can lead to delays, rejected court applications, or further disputes.
This guidance explains how eviction usually works where a sublet agreement is invalid and which notice is typically appropriate.
Understanding the issue or context
An invalid sublet often arises where a tenant has rented out the property without the landlord’s consent, in breach of the head tenancy agreement. In these situations, the people living in the property may believe they have tenancy rights, while the landlord may not recognise the sublet at all.
This creates confusion about:
- whether the occupiers are lawful tenants
- what legal protections apply
- how possession can be recovered
The key issue is that the landlord has no direct contractual relationship with the subtenants, and their right to occupy may be unlawful from the outset.
The legal rules or framework
Section 21 notices are used for “no-fault” evictions of assured shorthold tenants where a valid tenancy exists. This route relies on compliance with strict legal requirements, including deposit protection and prescribed information.
Where a sublet agreement is invalid because the original tenant had no right to grant it, the occupiers are unlikely to be recognised as assured shorthold tenants of the landlord. As a result, Section 21 is usually not appropriate.
In these circumstances, landlords typically rely on a Section 8 notice. This is a fault-based route and can be used where there has been a breach of the tenancy terms, such as unlawful subletting.
The relevant grounds may include:
- breach of the tenancy agreement
- unauthorised occupation
- rent-related grounds, if applicable
The correct grounds depend on the facts of the case and the status of the original tenancy.
Practical steps to take
If you believe the sublet is invalid and want to recover possession, the following steps can help clarify the process:
- Confirm the lack of consent
Review the head tenancy agreement to confirm subletting was prohibited or required permission. - Establish who is in occupation
Identify whether the original tenant is still involved or has disappeared. - Serve the correct notice
A Section 8 notice is usually the appropriate route where the sublet is unauthorised. - Use the correct legal grounds
Ensure the grounds relied upon accurately reflect the breach. - Apply to court if necessary
If the notice expires without compliance, a possession claim may be required.
These steps help ensure the eviction process is lawful and procedurally sound.
Common pitfalls to avoid
Landlords often encounter problems by:
- Using Section 21 where no valid tenancy exists
- Serving notices on the wrong parties
- Relying on incorrect or unsupported grounds
- Attempting informal eviction methods
Avoiding these pitfalls can prevent delays and legal complications.
Frequently Asked Questions
Can I use Section 21 if the sublet is invalid?
Usually not. Section 21 relies on a valid assured shorthold tenancy.
Why is Section 8 more appropriate?
Because it allows eviction based on breaches, including unauthorised subletting.
Do the subtenants have any rights?
They may have limited rights, but these are generally weaker where the sublet is unlawful.
What if the original tenant has disappeared?
This does not prevent eviction, but it can affect how notices are served.
Can I evict without going to court?
No. Eviction must follow the lawful process to avoid illegal eviction claims.
Should I seek legal guidance before serving notice?
Yes. Getting the notice wrong can invalidate the process.
