One of the quieter consequences of the Renters’ Rights Act is that a tenant is never really tied in any more. There are no fixed terms, so there is no "you signed for 12 months" — a tenant can give two months’ notice to quit at any time, including in the first month. For a landlord who let the property expecting a settled year, that is a real change to plan around.
This guide covers exactly how much notice a tenant must give, when that notice has to take effect, what a valid notice looks like, and what it means for you when a tenant leaves earlier than you hoped.
This is guidance, not legal advice. The rules are in the Renters’ Rights Act 2025 — check GOV.UK or legislation.gov.uk for your own situation.
The short answer
Since 1 May 2026, to end a periodic assured tenancy a tenant must give at least two months’ written notice. That is the default, and it is also effectively a ceiling: you cannot require a tenant to give more than two months. You can agree a shorter period with them in writing, but you cannot lock them into a longer one.
And crucially, there is no minimum tenancy length. A tenant does not have to stay six months, or even one — they can serve notice on day one and leave two months later. The fixed term that used to bind them for the initial period is gone.
When the notice has to take effect
Two months is the length; the end date usually matters too. By the long-standing rule for periodic tenancies, a notice to quit generally has to expire at the end of a rental period — on a day the rent is due, or the day before — rather than stopping partway through a month. So if rent is due on the 1st, a notice would typically run to the last day of a month, not the 14th, which can mean slightly more than two calendar months in practice. Section 20 sets the two-month length; the end-of-period timing comes from the general law on notices to quit, and as the landlord you can always accept a notice that ends on another day if the tenant leaving suits you.
You can waive that if you want the tenant out sooner or on a different day, but absent your agreement, the notice runs to the end of a period. So in practice a tenant giving notice mid-month is usually looking at slightly more than two calendar months before they actually go.
What a valid tenant notice looks like
A tenant’s notice to quit should be:
It does not need to be on a prescribed form the way your Section 8 notice does, but it does need to be clear and to give the right amount of time. If it is short or badly dated, it is not automatically valid, though as the landlord you can choose to accept a defective or shorter notice if the tenant leaving suits you.
Joint tenancies: where two or more tenants hold the tenancy jointly, a notice to quit from just one of them can, depending on the circumstances, end the whole tenancy for everyone. That is a trap worth understanding before you rely on the others staying.
What it means for landlords
The honest position: you can no longer assume a settled year from a new tenant. Someone can move in, find it does not suit them, and be gone in a little over two months, entirely lawfully. A few practical consequences:
How LetCompliance helps: when a tenant serves notice, the tenancy, the rent record and the compliance status are already in one place, so you can re-advertise the property, work your waiting list and reference the next tenant without starting cold — turning a two-month notice into a running start.

Joint tenancies: one notice ends it for everyone
This is the consequence landlords and sharers are most often unaware of, and it arrives without warning.
Where two or more people hold an assured periodic tenancy jointly, a valid notice given by any one of them ends the tenancy for all of them. The others do not get a vote, and they do not get to continue on the old agreement. A housemate who takes a job in another city can end a tenancy the remaining three wanted to keep.
Nothing is lost if you handle it properly, but you have to handle it deliberately. The remaining tenants do not simply carry on: what happens in practice is a new tenancy granted to whoever is staying, plus any replacement sharer. That means a new agreement, Right to Rent checks on anyone new, and a decision about the deposit — cleanest is to return the original and take a fresh one, protected with prescribed information served within 30 days.
Two practical defences. Say plainly in the agreement, at the start, that one tenant's notice ends the tenancy for all — most disputes here are surprise rather than disagreement. And when a sharer tells you informally that they are leaving, ask immediately whether they intend it as formal notice, because the answer changes what happens to everyone else. Our joint versus sole tenancy guide sets out the alternatives.
What to do the day a notice arrives
Treat this as the start of a process, not a piece of admin to file.
Check it is valid before you rely on it. In writing, from a tenant on the agreement, giving at least two months, with a clear end date. If it is ambiguous — "I'll be out around March" — write back proposing a specific date and ask them to confirm. An invalid notice you have relied on leaves you with an empty diary and a tenancy that never ended.
Acknowledge it in writing the same day. Confirm the date you have understood, the check-out arrangements, and how the deposit will be dealt with. This single email prevents most end-of-tenancy disputes.
Start the re-let immediately. Two months is enough time only if you begin at once. Book the check-out, ask whether they will allow viewings, and get the advert ready. Our void periods guide works through the arithmetic of why a fortnight matters more than most landlords assume.
Know that it cannot be withdrawn unilaterally. Once valid notice is given, the tenant cannot simply change their mind — withdrawal needs your agreement. If you have already re-let, you are entitled to say no, and you should say so in writing rather than leaving it ambiguous.
Plan the deposit. Once you and the tenant agree what is to be returned, the scheme rules require repayment within 10 days. Book the check-out early enough to compare against the inventory while the property is empty and before the next tenant arrives.
If they do not actually leave, the notice does not entitle you to change the locks. It becomes a possession matter — see what to do when a tenant will not leave.

Frequently asked questions
How much notice does a tenant have to give to leave in 2026?
At least two months’ written notice to end a periodic assured tenancy, since 1 May 2026 under the Renters’ Rights Act. You cannot require a tenant to give more than two months, though you can agree a shorter period with them in writing. Existing agreements signed before the change that give a shorter tenant notice (for example one month) generally remain binding.
Can a tenant leave in the first few months of a tenancy?
Yes. There is no minimum tenancy length any more — a tenant can give two months’ notice from day one and leave a little over two months later, entirely lawfully. The fixed term that used to bind a tenant for an initial period is gone, so you cannot assume a settled year from a new tenant.
When must a tenant’s notice to quit take effect?
Section 20 sets the length at two months. Separately, by the long-standing rule for periodic tenancies, a notice to quit generally has to expire at the end of a rental period — a day the rent is due, or the day before — rather than stopping partway through a month, which can mean slightly more than two calendar months. As the landlord you can accept a notice that ends on another day if the tenant leaving suits you.
