Shared Housing and Flatmate Rights

When you move into shared housing, your legal position depends primarily on what type of agreement you have signed.

In a joint tenancy, all flatmates sign the same tenancy agreement and are all named tenants. You are jointly and severally liable for the rent — meaning your landlord can pursue any one of you for the full rent if others fail to pay. This also means one tenant cannot normally end the joint tenancy without the agreement of all others (though case law is developing in this area following the Renters' Rights Act 2025).

In an individual tenancy, each occupant has a separate agreement with the landlord covering their own room (and usually shared use of communal areas). You are only responsible for your own rent and cannot usually be held liable for a housemate's failure to pay. This arrangement is common in houses in multiple occupation managed by professional landlords or letting agents.

If you are unsure which applies to you, check whether you signed the same document as your flatmates or separate documents, and whether all names appear on one agreement.

A house in multiple occupation (HMO) is a property occupied by three or more people from two or more separate households who share facilities such as a bathroom or kitchen. Larger HMOs — those with five or more occupants from two or more households — require a mandatory licence from the local authority. Some councils operate additional or selective licensing schemes covering smaller properties.

Licensed HMOs must meet minimum room size standards (since 2018, a minimum of 6.51 sq metres for a room occupied by one adult), fire safety requirements, adequate kitchen and bathroom facilities, and other management standards. Landlords of unlicensed HMOs face significant fines and may be required to repay rent under a Rent Repayment Order.

As a tenant in an HMO, you are entitled to:

• A copy of the HMO licence on request
• A safe, well-maintained property free from Category 1 hazards
• Adequate fire safety provisions including smoke alarms, fire doors, and safe escape routes
• Properly maintained shared facilities

In a joint tenancy, disputes between flatmates can be particularly difficult because your liability is collective. If a flatmate stops paying rent, the landlord can pursue you for the shortfall. If one flatmate causes damage, all tenants may be held responsible through the deposit.

Steps to manage flatmate disputes include:

• Create a flatmate agreement at the start setting out expectations on bills, cleaning, guests, and noise — even if informal, it can help resolve disputes.
• Communicate concerns in writing where possible so there is a record.
• If a flatmate is not paying their share of rent, try to resolve this directly before it escalates to arrears that affect all tenants.
• If a flatmate wants to leave a joint tenancy early, all remaining tenants and the landlord should agree to a formal change to the tenancy agreement (a deed of surrender or a new agreement).

Citizens Advice can provide guidance on resolving shared housing disputes, and some councils offer mediation services for tenancy disputes.

When one flatmate wants to leave a joint tenancy, the legal position affects all remaining tenants significantly. In a joint tenancy, each tenant has equal rights and responsibilities under the same agreement, so a departure must be handled carefully to avoid unintended consequences.

The departing tenant cannot simply walk away. Their name remains on the tenancy — and their liability for rent — until the tenancy is formally changed. Options include:

• Deed of assignment: With the landlord's consent, the departing tenant's interest can be transferred to a new incoming tenant. This substitutes one name for another on the tenancy agreement and releases the departing tenant from future liability.
• New tenancy agreement: The landlord may prefer to end the existing tenancy and grant a fresh one to the remaining and any new tenants. This gives the landlord an opportunity to update terms and potentially change the rent.
• Surrender and re-grant: All tenants and the landlord agree to end the existing tenancy entirely, allowing a fresh start. This approach works well when the household is substantially changing.

Until the tenancy is formally varied, the departing flatmate remains legally liable for rent even if they have physically left. Equally, remaining tenants cannot force a departing flatmate's name off the agreement without the landlord's cooperation. If the landlord is unresponsive, Citizens Advice and Shelter can advise on next steps. Always get any agreed changes in writing and keep copies.
