What to Do If a Commercial Tenant Refuses to Leave After Lease Ends in the UK

If you own a commercial property, you might often wonder what to do if a tenant doesn’t leave when their lease ends. What happens if a tenant damages property without permission or goes on land next door? Are you, as the landlord, in charge of what they do? And is there a way to get your money back, like mesne profits?

These are important questions, but they can be hard to answer. We at Adam Bernard Solicitors help business landlords with these kinds of issues all the time. Below, we break down your legal situation in simple terms and help you figure out when you’re in danger and when you can get money.

What Is Tenant Trespass?

Tenant trespass is when a tenant stays on your property after their lease has ended and you haven’t given them permission. People often call this “holding over.” From then on, they are not allowed to be on the property. In some cases, tenants also go beyond the property they rented or use areas they aren’t allowed to.

What Is Mesne Profits?

Mesne profits are the money a landlord can get from a tenant who is living in a property without permission. Most of the time, this amount is based on how much the property would rent for on the open market during the time it was illegally occupied.

Important Point: Mesne profits are not a fine. They are meant to pay you, the landlord, for not being able to use your property.

When Can a Landlord Claim Mesne Profits?

In most cases, you can claim mesne profits if

  • The tenant stays even though the lease has ended and there is no new agreement.
  • The lease was ended (for example, by forfeiture or expiration), but the tenant hasn’t left yet.
  • The tenant isn’t paying rent or won’t talk to you.
  • This is a common problem for landlords who lose money and feel stuck. We can help you file a legal claim for mesne profits based on the fair rental value.

Can landlords be held responsible for trespassing?

Yes, but it depends on what is going on. In these situations, you as a landlord could be held responsible for trespassing:

  • You break the law by going into the tenant’s home without their permission or a court order.
  • You try to forcibly kick a tenant out without following the right legal steps.
  • You let a new tenant move in before the old one has moved out.

This could end up costing a lot of money. Damages for a landlord entering a property without permission can be large and can also hurt the landlord’s reputation.

Can a Landlord Be Liable for Their Tenant’s Trespass?

A lot of commercial landlords worry about this. In most cases, you are not responsible for your tenant’s trespass unless you gave them permission or told them to do it.

  • You knew about it and didn’t do anything.
  • You still have some control over the property, like shared spaces or land next to it.
  • As the property owner, you could still be sued if a tenant uses another unit or part of the building without permission.

Frequently Asked Questions

What can I do if a commercial tenant refuses to leave after their lease ends?

If a commercial tenant continues to occupy your property after the lease has ended and without your permission, they are considered a trespasser under UK property law. You cannot change the locks or forcibly remove them without going through the correct legal channels. You must serve formal notice and apply to the court for a possession order. During this period, you may also be able to claim mesne profits for the unlawful occupation. Contact a solicitor early to protect your rights and avoid procedural mistakes.

What are mesne profits and how can a landlord claim them in the UK?

Mesne profits are financial compensation a landlord can claim from a tenant who remains in possession of the property after the lease ends without consent. It represents the fair market rental value of the property during the period of trespass. To claim mesne profits in the UK, you must demonstrate that: The tenant’s right to occupy has ended. The tenant has not vacated the premises. You did not grant any new lease or licence. Claims are typically brought through the civil court system, and having expert legal representation helps strengthen your case.

What if my tenant caused a trespass on someone else's land?

You may not be directly liable, but if you knew about it and allowed it, you could be implicated.

Is it legal to change the locks on a commercial property after a lease expires?

No, it is illegal to change the locks on a commercial property while a tenant is still in occupation, even if the lease has expired. Doing so without a court order constitutes unlawful eviction under UK law. You must follow the legal eviction process and obtain a possession order from the court. Taking matters into your own hands can result in fines, compensation claims, and reputational damage.

What steps should I take to avoid tenant trespass issues in the future?

To prevent future disputes and trespass problems: Use professionally drafted commercial leases Clearly define property boundaries and usage terms Include clauses covering termination, forfeiture, and damages Serve proper notices before lease expiry Keep a record of all communications and rent payments Act promptly when issues arise—delays reduce your options
