The twelve-month re-let ban — what your landlord risks if they evict you and don't sell
There's a rule in the Renters' Rights Act 2025 that most landlords don't fully appreciate, and that significantly changes the maths of evicting a tenant in order to sell. It's called the twelve-month re-let ban. This guide explains what it is, why it exists, and what it means for any conversation about your tenancy.
What the rule says
If your landlord serves a Section 8 notice citing Ground 1A — sale of dwelling-house — and then doesn't actually sell the property, they are prohibited from re-letting it for twelve months from the date specified in the notice.
In practice, this means the landlord cannot:
- Grant a new assured tenancy of the property.
- Grant any other tenancy of more than six months.
- Market the property for rent on Rightmove, Zoopla, OnTheMarket, OpenRent, SpareRoom, or any of the other major rental portals.
- Advertise the property for rent through a letting agent.
The same rule applies to Ground 1 (occupation by landlord or family). If the landlord serves notice citing one of these grounds and then doesn't proceed with the stated reason, the property has to sit unlet for a year.
Why this rule exists
The intention behind the rule is to prevent landlords using Ground 1A as a backdoor route to no-fault eviction. Under the old Section 21 regime, a landlord could simply ask any tenant to leave, with no reason needed. Under the new system, every notice has to specify a ground — and the ground has to be true.
The re-let ban enforces the truthfulness requirement. A landlord who serves Ground 1A notice "to sell" but actually wants to evict for some other reason (disliking the tenant, hoping to charge a higher rent to a new tenant, deciding to keep it for themselves without moving in) faces a significant penalty if the real reason later emerges: twelve months of forgone rent.
Why this matters to you
This is the rule that quietly shifts the negotiating dynamics between landlord and tenant in a sale situation.
A landlord considering serving Ground 1A notice now faces a binary commitment. Either they sell within twelve months, or they have an empty property they cannot re-let. There's no middle ground. There's no "I'll serve notice, see if a tenant will pay more, and then change my mind." Once the notice goes in, the choice is sell or absorb a year of empty property.
For a landlord on a £1,500-a-month flat, twelve months of empty property is £18,000 of forgone rent, plus whatever the carrying costs are during the empty period — mortgage interest, service charge, council tax, insurance, maintenance. The total cost of failing to sell is often £25,000 to £30,000 on a typical residential property. That's a serious commitment to make in advance of knowing whether the property will actually attract a buyer at the price the landlord wants.
The practical consequence is that landlords now think harder before serving notice. Many who would previously have used Section 21 to "test the market" by getting vacant possession first and then deciding whether to sell are now reluctant to commit. Either they sell with the tenant in place (which usually means accepting a discount of around 20%), or they commit to the eviction route knowing they have to follow through with the sale.
How this changes the conversation
For tenants, this is leverage. A landlord who has served Ground 1A notice is a landlord who needs the sale to work. They cannot afford for it to fall through. They cannot afford for the buyer to walk away because of a contested or delayed eviction. They cannot afford a twelve-month void if the market doesn't deliver the price they want.
This makes them, often for the first time, genuinely interested in arrangements that increase the probability of the sale completing on time at the expected price. Umoja's co-operative exit is one such arrangement. The tenant agrees to leave on a known date, in exchange for a financial reward. The landlord knows when they'll have vacant possession and can give that date to a buyer with confidence. The buyer doesn't have to worry about an eviction process delaying or derailing their purchase. The sale is more likely to complete cleanly and on time, which is exactly what the landlord needs.
A landlord who serves notice but hasn't yet committed irreversibly to the standard eviction route is the most receptive audience for this idea. They can see the twelve-month risk in front of them, and they're looking for ways to reduce it.
What to do with this information
If your landlord has mentioned selling but hasn't yet served notice, you can use this rule to inform the conversation gently. Something like: "I know the new rules around Ground 1A include a twelve-month re-let ban if the sale doesn't complete — worth checking with your solicitor. There's a service called Umoja that handles co-operative sales and avoids that risk entirely."
If your landlord has already served notice, the same point applies more sharply. They've already committed to the twelve-month risk. Umoja's co-operative exit reduces it. They have every reason to consider it.
We've written about how to raise this conversation calmly in How to talk to your landlord about a co-operative sale.
One thing to be careful of
The re-let ban only triggers if the landlord doesn't sell. A landlord who serves notice and then completes a sale within the twelve-month window is in the clear; the rule has no further effect. So this isn't a guaranteed safety net. It's a downside risk for the landlord, not a guaranteed benefit for you.
But it's a downside risk that didn't exist before, and it's significant enough to change the calculus in most landlord-side conversations about selling. Knowing it exists, and knowing your landlord knows it exists, changes the kind of conversation you can have.
