Changing tenants mid tenancy without losing protection
Understanding how to manage tenant changes mid-tenancy is crucial for landlords to maintain legal protection and avoid disputes. This guide outlines the proper procedures for England from 2026.

Overview
Changing tenants mid-tenancy, often due to a tenant leaving early or a new person joining an existing household, requires careful legal navigation to preserve your landlord protections. From 2026, with the Renters' Rights Act 2025 in force, the process typically involves either assigning the existing tenancy, creating a new tenancy agreement for all remaining and new tenants, or varying the original agreement. The correct approach depends on the specific circumstances and requires meticulous documentation to ensure all parties are legally bound and protected. Failure to follow correct procedures can invalidate tenancy terms or make eviction proceedings difficult later.
Why it matters
Incorrectly managing tenant changes mid-tenancy can lead to significant legal and financial repercussions for landlords. You risk losing the ability to enforce tenancy terms, recover unpaid rent, or lawfully regain possession of your property. Without a clear and legally sound agreement, new occupants may not be properly liable for rent or property damage, and the original tenants might remain liable even after moving out. This can result in costly disputes, court proceedings, and substantial financial losses if the situation is not handled diligently and professionally.
Legal requirements
- All new and remaining tenants must sign a legally binding tenancy agreement, or an assignment agreement, reflecting their obligations.
- Any new tenancy deposit received must be protected in an authorised scheme within 30 days and prescribed information issued to all tenants.
- The property's EPC, Gas Safety Certificate, and EICR must be valid and shared with any new tenants at the start of their occupancy.
- All Right to Rent checks must be diligently performed for every new adult tenant or occupant aged 18 or over.
- Any new guarantor agreements must be properly executed as deeds and clearly reference the specific tenancy agreement they relate to.
- The terms of the original tenancy must be formally varied or superseded by a new agreement to correctly reflect the change in tenants.
- The landlord must not charge any prohibited fees in connection with the tenancy change, as stipulated by the Tenant Fees Act 2019.
- All parties, including any remaining tenants, must explicitly agree to the change in writing to avoid future disputes.
- Where applicable, local authority HMO licensing requirements must be reviewed and updated to reflect any change in occupant numbers.
- Adequate insurance cover must be maintained for the property, potentially updating policies to reflect any changes in occupancy or use.
Common mistakes
- Allowing a new person to move in without formally adding them to the tenancy agreement or creating a new one.
- Failing to conduct Right to Rent checks on new occupants, leading to potential civil penalties.
- Not protecting a new or adjusted tenancy deposit, or failing to re-issue prescribed information for a new tenancy.
- Assuming a guarantor for the original tenant automatically covers a new tenant or a new agreement.
- Charging prohibited fees, such as 'admin fees' for new tenant referencing or agreement changes.
- Not obtaining explicit written consent from all existing tenants for a new tenant to join the agreement.
- Failing to update safety certificates or provide them to new tenants when a new tenancy is created.
- Overlooking the impact of tenant changes on HMO licensing requirements or property insurance policies.
- Not properly documenting the departure of an outgoing tenant, leaving them potentially liable.
- Attempting to assign a tenancy without formally executing a deed of assignment with all necessary parties.
Practical guidance
- Assess the specific situation to determine whether a deed of assignment, a variation of contract, or a new tenancy agreement is most appropriate.
- For new tenants, conduct thorough referencing, including credit checks and Right to Rent checks, before they move in.
- Obtain explicit written consent from all existing tenants and the outgoing tenant, if applicable, for any proposed changes.
- Draft a comprehensive new tenancy agreement, or a deed of assignment, clearly outlining the responsibilities of all parties.
- Ensure any new tenancy deposit is protected in a government-approved scheme and all prescribed information is served within 30 days.
- Provide new tenants with copies of the EPC, Gas Safety Certificate, and Electrical Installation Condition Report.
- If a new tenancy is created, re-issue any statutory notices, such as the 'How to Rent' guide, to all tenants.
- Update any existing guarantor agreements or create new ones, ensuring they are executed as deeds and reference the new agreement.
- Carefully document the checkout process for any outgoing tenant, including taking meter readings and finalising deposit deductions.
- Keep detailed records of all communication, agreements, and safety certificates, as highlighted in our guide on tenant communication records that protect landlords.
Option 1: New Tenancy Agreement for All
The most robust and often recommended approach when changing tenants, especially if one tenant is leaving and another is joining, is to terminate the existing tenancy and create an entirely new one. All remaining tenants and the new tenant(s) would sign this fresh agreement. This method ensures all parties are equally and clearly bound by the latest terms and conditions. It also allows for the opportunity to update any clauses, adjust the rent if agreed, and re-set the tenancy deposit protection. You must re-protect any deposit and re-issue the prescribed information. Remember to conduct new Right to Rent checks for any incoming tenants. This process provides the clearest legal standing and minimises ambiguity regarding liability for rent and property condition going forward. Ensure the outgoing tenant formally surrenders their interest in the original tenancy.
Option 2: Deed of Assignment
A deed of assignment legally transfers the rights and obligations of an existing tenant to a new tenant. This is only possible if the original tenancy agreement permits assignment, or if all parties including the landlord, the outgoing tenant, and the incoming tenant agree. The original tenancy itself continues, meaning the terms and conditions remain unchanged. A deed of assignment must be formally executed as a deed, which typically requires a witness. While it can be simpler than creating a whole new tenancy, it means you cannot alter terms or adjust the rent easily. Crucially, if the outgoing tenant is assigned out, they generally cease to be liable for the tenancy's obligations. Always obtain legal advice before pursuing assignment to ensure it is correctly drafted and executed, especially given the complexities of joint and several liability. Right to Rent checks are still mandatory for the incoming assignee.
Option 3: Varying the Existing Agreement
In some less common scenarios, particularly if a new tenant is simply joining an existing household and no tenant is leaving, you might vary the existing agreement. This involves creating a formal written addendum, signed by all original tenants and the new tenant, which explicitly states the addition of the new tenant to the tenancy. The addendum should specify that the new tenant is jointly and severally liable with the existing tenants for all terms of the original agreement. While seemingly straightforward, varying an agreement can be legally intricate. It is generally less secure than a new tenancy, as it might not fully re-set the legal relationship. Expert advice is recommended to ensure the variation is legally sound and effectively binds the new tenant to all obligations, including rent and property damage. Remember to update any deposit protection information accordingly.
Managing Deposit Protection and Guarantors
Whenever tenants change, especially when creating a new tenancy, careful attention must be paid to the tenancy deposit. For a new tenancy, the entire deposit must be re-protected in an approved scheme within 30 days and new prescribed information issued to all new and remaining tenants. If an outgoing tenant is replaced, their portion of the deposit should be handled fairly. This often means the incoming tenant pays their share to the outgoing tenant directly, and the overall protected amount remains the same, but the prescribed information might need updating for the new tenant. For details on protecting deposits, refer to government guidelines. Guarantor agreements are tenancy-specific, so a new tenant joining or an entirely new tenancy agreement will almost certainly require a new guarantor deed if you wish to retain that security. A guarantor for an old tenancy will not automatically guarantee a new one. See our guide on using a guarantor for a tenancy for more information.
Right to Rent Checks and Safety Certificates
The immigration act requires landlords to conduct Right to Rent checks on all adult occupiers aged 18 or over. This applies to every new tenant, even if they are joining an existing tenancy or replacing an outgoing one. Failure to perform these checks can lead to significant penalties. You must retain clear records of all checks. Furthermore, all statutory safety certificates must be in place and provided to any new tenant. This includes a valid Energy Performance Certificate EPC, a Gas Safety Certificate if there's a gas supply, and an Electrical Installation Condition Report EICR. Even if the certificates were provided to original tenants, a new tenancy agreement or a significant change to the tenant roster often necessitates re-issuing these documents to ensure all current occupants have received them. Proper documentation is key, as discussed in our article on tenant communication records that protect landlords.
Rules in Scotland, Wales, and Northern Ireland
The legal framework for residential tenancies differs significantly across the UK. In Scotland, the predominant tenancy is the Private Residential Tenancy PRT, governed by the Private Housing Tenancies Scotland Act 2016. PRTs cannot be assigned. If a tenant wishes to leave and be replaced, a new PRT must be created for the remaining and new tenants. In Wales, the Renting Homes Wales Act 2022 introduced 'occupation contracts'. These also have specific rules for joint contracts and replacements, often requiring a new contract or a 'variation' document. Northern Ireland has its own tenancy legislation, primarily the Private Tenancies Northern Ireland Act 2022, which also details how joint tenancies and changes in tenants are managed. Landlords operating in these devolved nations must consult the specific legislation and guidance applicable to their region, as the procedures outlined for England will not apply directly.
Frequently asked questions
Can I simply add a new tenant's name to the existing tenancy agreement?
While it might seem simple, physically adding a name to an existing signed agreement is not legally robust. For proper legal standing, you should formally vary the agreement with an addendum signed by all parties, or ideally, create a completely new tenancy agreement for all current and new tenants. This ensures the new tenant is fully bound and all liabilities are clear.
What happens to the deposit if one tenant leaves and another joins?
If a new tenancy is created, the entire deposit must be re-protected and prescribed information re-issued. If the original tenancy continues via assignment or variation, the outgoing tenant's share is usually refunded by the incoming tenant directly, and the landlord maintains the original protected deposit for the continuing tenancy. Always update the deposit scheme provider with the new tenant's details.
Do I need to do new referencing for a tenant replacing an old one?
Yes, absolutely. Every new tenant should undergo comprehensive referencing, including credit checks, employment verification, previous landlord references, and crucially, Right to Rent checks. This is vital to ensure the new tenant is suitable and legally allowed to reside in the UK, protecting your interests and complying with legal obligations.
Can the departing tenant remain liable for the rent if I don't sign a new agreement?
If an outgoing tenant is part of a joint and several liability agreement and is not formally released from the tenancy, they can remain legally liable for the rent and other obligations even after moving out. This is why a formal surrender or assignment, or a new tenancy agreement, is essential to properly document their departure and release them from liability.
What fees can I charge for changing tenants mid-tenancy?
Under the Tenant Fees Act 2019, landlords in England can only charge a maximum of £50 including VAT for varying, assigning, or novating a tenancy. This is the only permissible fee for tenant changes, unless the landlord can demonstrate that the reasonable costs incurred are higher, in which case a higher fee may be charged if documented. Charging other 'admin' or 'referencing' fees is prohibited.
Do I need new guarantor agreements if a new tenant joins?
Yes, almost certainly. Guarantor agreements are specific to the tenancy agreement and the tenants they cover. If a new tenant joins, or a new tenancy agreement is created, any existing guarantor agreement will likely no longer be valid for the new arrangement. A new guarantor deed, properly executed, will be required for the new tenant or if the scope of the guarantee needs to cover the new tenancy.
What if an existing tenant doesn't agree to a new tenant?
If one of the existing joint tenants does not agree to the addition of a new tenant or the creation of a new tenancy, you cannot legally proceed with the change without their consent. In such situations, the existing tenancy continues, and the landlord may need to consider serving notice to end the entire tenancy if the living arrangement is unworkable or the original fixed term is expiring.
Are there different rules for HMOs when changing tenants?
Yes, for Houses in Multiple Occupation HMOs, changing tenants can affect licensing requirements. If the change alters the number of households or individuals, or the total number of occupants, you may need to notify the local authority. This could potentially trigger a requirement for a new or updated HMO licence application. Always check your specific licence conditions and local council rules.
