Landlord requiring replacement tenant to leave

Short answer

A landlord generally cannot force you to find a replacement tenant, but until your tenancy is lawfully ended you usually remain liable for the rent. Finding a replacement is often the practical way to stop that liability, not a legal duty imposed on you. Whether the landlord can insist on it as a condition of release depends on the type of agreement you hold and, increasingly, on recent changes to the law.

Which type of agreement do you have?

The answer turns on the kind of accommodation and contract you are in, so this is the first thing to pin down.

Private landlord or letting agent tenancy. Most student lets in the private sector have historically been assured shorthold tenancies (ASTs), usually for a fixed term such as 12 months. If you are still in a fixed term, you are contractually bound to pay the rent for the whole term unless the contract lets you leave early or the landlord agrees to release you. The landlord cannot make you find a replacement, but they also do not have to release you, so in practice offering a suitable replacement is the most reliable route out.

University-owned or purpose-built student accommodation (PBSA). These are often licences to occupy rather than assured tenancies, and the written contract governs. Many providers who are members of a national accreditation code (such as the ANUK/Unipol National Codes) operate a policy that lets you leave if you find a suitable replacement occupier to take over the remainder of your contract. That is a contractual concession, not a legal obligation you can be forced to perform.

The important recent change in the law

The law in this area has changed significantly. The Renters’ Rights Act 2025 abolishes fixed-term assured shorthold tenancies, converting existing and new assured tenancies into assured periodic (rolling) tenancies. Under that regime a tenant can generally end the tenancy by giving two months’ notice at any time, which removes the trap of being locked into a fixed term.

This matters because if your agreement is an assured tenancy that has become a periodic tenancy under the new rules, you may be able to end it simply by serving two months’ notice, without needing a replacement tenant at all. You should check whether your specific agreement has already converted, because the conversion depends on the type of tenancy and the timing.

Two cautions. First, purpose-built student accommodation and university halls are frequently structured as licences or fall outside the assured tenancy regime, so the two-months’-notice right may not apply to them in the same way, and the written contract terms remain central. Second, the exact commencement and transitional position matters, so the precise date your agreement started and its legal nature will determine which rules apply to you.

“Find a replacement” as a contract term

If your written contract expressly says you may only be released early if you provide an acceptable replacement, that clause is capable of being enforceable, but it is not a blank cheque for the landlord.

The landlord must generally act reasonably and cannot unreasonably refuse a suitable replacement you put forward. If you produce a suitable substitute and the landlord simply refuses, that may itself be unreasonable.

Any charges attached to early release must be genuine. For most residential tenancies granted or renewed after 1 June 2019, the Tenant Fees Act 2019 restricts what a landlord or agent can charge. An early-termination charge cannot exceed the landlord’s genuine loss, or the amount of rent still owed, whichever is lower. A flat “admin” or re-let fee dressed up as a penalty is likely to be prohibited.

If the clause is buried in a consumer contract and creates a significant imbalance to your detriment, it may be challengeable as an unfair term under the Consumer Rights Act 2015.

Your duty to pay versus the landlord’s duty to mitigate

Even where you are bound for a fixed term, you are not simply liable indefinitely regardless of what the landlord does. If you leave and the landlord treats the tenancy as at an end, or re-lets the room, they cannot recover rent for a period during which someone else is paying. In practice this is why replacing yourself is useful: once a new tenant is in and paying, your exposure falls away.

Where the landlord holds you to a fixed-term contract as a debt for the rent, the position on mitigation is more limited than in an ordinary damages claim, which is precisely why the type of agreement matters. This is another reason to establish whether you hold an assured tenancy, a fixed-term contractual tenancy, or a licence.

Joint tenancies

If you signed a joint tenancy with housemates, be careful. Under a joint tenancy you are usually jointly and severally liable, meaning each tenant can be pursued for the whole rent. One tenant cannot normally leave and end the tenancy for everyone, and any replacement will usually require the agreement of the landlord and, in practice, the other joint tenants, often documented by a deed of surrender and re-grant or a formal assignment. Check whether your document is a single joint tenancy or separate individual agreements for each room, because this changes both your liability and the mechanics of substitution.

Practical next steps

1. Read your agreement carefully and identify exactly what it says about early termination, break clauses, notice, replacement tenants and any charges. Note the start date and whether it is described as a tenancy or a licence.

2. Work out which legal regime applies to you: a still-running fixed-term AST, an assured periodic tenancy under the Renters’ Rights Act 2025, a purely contractual tenancy, or a licence for PBSA or halls. If it is now periodic, consider simply serving the required notice.

3. Ask the landlord or provider in writing what they will accept for release, and whether they will help advertise the room. Many providers, especially National Code members, actively assist and this is often the smoothest route.

4. If they demand a replacement, put forward a suitable candidate promptly and in writing, and ask them to confirm acceptance or give reasons for refusal. Keep a record, because unreasonable refusal weakens their position.

5. Scrutinise any early-release or re-letting fee against the Tenant Fees Act 2019. Do not simply pay a penalty that exceeds their genuine loss or the outstanding rent.

6. If the accommodation is a National Code member or a university provider, use their internal complaints process, and then escalate to the relevant redress scheme. For accredited providers this can include the code administrator; for many private lettings, complaints can go to a property redress scheme or, for university-owned provision, potentially the Office of the Independent Adjudicator once internal routes are exhausted.

7. If you are struggling, your students’ union advice service and your university accommodation office can often negotiate on your behalf, and Citizens Advice and Shelter provide free housing guidance.

What would change the answer

The outcome depends heavily on facts you have not yet given: whether the property is private, university-owned or PBSA; whether your document is a tenancy or a licence; the start date and whether it has converted to a periodic tenancy; whether it is a joint or individual agreement; and the precise wording of any early-termination and replacement clauses. If you tell me those details, and quote the relevant clause, I can give you a much more targeted answer on whether the landlord can lawfully insist on a replacement in your particular situation.
