Joint tenancy, room-only or lodger: which one are you?

Two people can live in identical rooms in identical houses and have completely different legal positions. What matters is not the house, it is the paperwork. Before you sign anything, work out which of these three setups you are being offered.

First, the 2026 baseline

Since 1 May 2026, new private tenancies in England are periodic assured tenancies. There is no fixed term. The tenancy rolls month to month, you can leave with two months' written notice, and the landlord needs a legal ground to end it. Existing assured shorthold tenancies converted to the same system automatically. So the old question of "how long am I locked in for" has mostly been replaced by "who is on the agreement and what am I liable for".

Joint tenancy: one agreement, everyone on it

The classic friends-renting-a-house setup. Everyone signs one agreement and the law treats you as a single tenant. The phrase to understand is joint and several liability: the landlord can pursue any one of you for all of the rent and any damage, anywhere in the house. If a housemate stops paying, that is legally your problem too, which is exactly why choosing the right people matters more than choosing the right sofa.

Be careful with notice. On a periodic joint tenancy, a valid notice to quit served by one joint tenant ends the tenancy for everyone. If one of you wants to go and the rest want to stay, do not let anyone serve notice unilaterally. Talk to the landlord about replacing the leaver instead, either with a fresh agreement or a formal assignment. A landlord can charge up to £50 for a change of tenant, nothing more.

Room-only tenancy: your own agreement for your own door

Here each person has a separate agreement covering their room plus shared use of the kitchen, bathroom and living areas. You are only liable for your own rent. If the person across the landing disappears owing two months, that is the landlord's loss, not yours.

The trade-offs: the landlord controls who fills empty rooms, so you may not choose your housemates, and the property is usually a house in multiple occupation, which brings licensing and extra safety duties for the landlord. Communal areas are the landlord's responsibility to maintain. Room-only setups are common in larger shares and in most listings where you join an existing household.

Lodger: living in the landlord's own home

If you rent a room in the home your landlord actually lives in, and you share living space with them, you are almost certainly a lodger, which the law calls an excluded occupier. This is the lightest arrangement of the three. You have a licence rather than a tenancy, the landlord only needs to give reasonable notice to end it, usually one rent period, and no court order is needed for you to be asked to leave. Deposit protection rules do not apply either.

None of that makes lodging bad. It is often the cheapest and most flexible way to live in an expensive city. It does mean the relationship is the contract, so meet properly before you commit. Get the basics in writing: rent, what bills are included, notice, and house rules.

Rent-to-rent and other things to watch

Sometimes the person letting you a room is not the owner but a middle company renting the whole house and subletting rooms. That can be legitimate, but you should know who your actual landlord is, whether the owner has consented, and who holds your deposit. Ask directly and get names in writing. A national landlord database is being introduced later in 2026 which will make checking easier.

Whatever the setup, check before signing: exactly who is named on the agreement, how much the deposit is and who protects it, what is included in the rent, and what the inventory says. If you are joining strangers, meet them first. The agreement decides your legal position, but the people decide your year.
