Shared owners who rent out their homes will lose access to Section 21 from 1 May and will have to use the Renters Rights Act possession grounds instead, under new government guidance published ahead of the switch-over.
For landlords, the point is narrower than the wider private rented sector changes but still important. Shared owners who have been allowed to sublet will no longer be able to rely on a no-fault route to recover possession. If they need the property back, they will usually have to use Section 8 on the basis that they are moving back in or selling, give at least four months’ notice and wait until the tenant has been in place for 12 months before possession can take effect.

Shared owners must follow the same new tenancy rules
New government guidance for shared owners who are renting out their home says the new regime applies even where a subletting permission from the superior landlord still refers to assured shorthold tenancies or Section 21. In practice, that means the paperwork sitting behind many older subletting arrangements will no longer match the law from 1 May.
The guidance also says shared owners may need to give tenants the 2026 Renters Rights Act information sheet. That pulls them into the same compliance system now bearing down on mainstream landlords and agents, where the issue is no longer just understanding the reform but proving each step was handled properly.
That matters because shared ownership subletting often operates on borrowed time. Permission may be temporary, linked to personal circumstances, or granted on the understanding that the owner will return or sell. Once Section 21 goes, those exit routes become slower and more conditional. A shared owner who needs a quick return to the property may find the legal route no longer lines up with the practical timetable they had in mind.
Subletting permissions will need more planning
The government has also told registered providers they should give shared owners at least six months’ notice if subletting permission is being brought to an end in cases where the permission starts on or after 1 May, or where an existing permission is due to expire on or after 1 December 2026. If the matter ends up in court, providers are expected to extend permission long enough for the possession process to finish.
This follows Landlord Knowledge’s report on the government’s Renters Rights Act information sheet before 1 May, which highlighted how the compliance burden is shifting from headline reform to everyday admin. The new shared ownership guidance shows the same pattern: what looked like a niche tenure issue is turning into another set of documents, notice periods and deadlines that landlords must get right.
A second practical wrinkle is the 12 month no re-let restriction that follows use of the selling ground. Shared owners can be exempt, but only if they meet specific conditions. For existing subletting arrangements, ministers say owners can use transitional arrangements if they tell tenants by 31 May 2026 that they are shared owners and that the restriction may not apply to a later letting. That deadline is easy to miss and could matter if a sale falls through and the property needs to be let again.
For landlords and investors, this is another sign that the Renters Rights Act is producing awkward edge cases outside the standard buy-to-let model. The law is supposed to simplify tenure rules, but in shared ownership it may do the opposite by forcing subletting arrangements, provider policies and older permissions to be rewritten around a new possession framework.
Landlords wanting the wider context should also look at Landlord Knowledge’s recent coverage of the government’s tenant guide and the rising compliance pressure before 1 May, because the shared ownership changes sit inside the same broader push toward evidence, notices and prescribed information.
What this means for landlords
- If you sublet a shared ownership home: check whether your current permission still refers to ASTs or Section 21 and get advice before 1 May.
- Watch for: the 31 May 2026 deadline to notify existing tenants if you may need the shared owner exemption from the 12 month no re-let restriction.
- If your provider is ending permission: work backwards from the new four month notice period and the 12 month minimum tenancy rule, not your old subletting timetable.
- Bottom line: shared ownership landlords are being pushed into the full RRA rulebook, with less room for informal workarounds.
Editor’s view
Shared ownership has always sat awkwardly between owner-occupation and private renting. The new guidance makes clear that once a shared owner becomes a landlord, ministers expect the same discipline on notices, documents and possession rules as everyone else. The risk is that many owners will only discover that when they need the property back quickly.
