Sitting tenant

A sitting tenant is someone who remains in a property under an existing tenancy when the rental property is sold or transferred to a new owner. The tenancy continues automatically on the same terms. The buyer steps into the role of landlord, and the tenant is not required to leave simply because ownership has changed. Their rights and the rent level are preserved exactly as they were under the previous owner.

The term is older in origin than tenant in situ, which is used in property listings and conveyancing, and tends to arise in discussions of tenant rights and security of tenure. Both terms describe the same underlying situation. The key practical questions for a sitting tenant are: how strong is their security of tenure, can they be evicted, and at what rent? The answers depend almost entirely on when and how the tenancy was created.

How long before a tenant becomes a sitting tenant?

In practice, a tenant becomes a sitting tenant at the moment the property is sold or transferred while they are in occupation under a valid tenancy, it is not about length of residence but about the property changing hands. However, in everyday usage the phrase also describes a tenant who has remained in occupation beyond the original fixed term without a new formal agreement, rolling on a periodic tenancy month by month or week by week. A tenant on a rolling periodic tenancy without a current signed contract is still a legally recognised tenant, and their rights are broadly the same as any assured tenant, the absence of a written agreement does not remove their statutory protections.

Tenancy types: the critical distinction

The strength of a sitting tenant's rights depends almost entirely on when their tenancy was created.

Regulated tenancies (before 15 January 1989) - Tenants whose tenancy began before 15 January 1989 are almost certainly protected by the Rent Act 1977. These are called regulated, protected, or secure tenancies. They provide the strongest tenant protections in English property law: the tenant has the right to remain in the property indefinitely, cannot be evicted except on a narrow set of grounds, and pays a "fair rent" registered by the Valuation Office Agency rather than a market rent. Fair rent is typically well below current market levels, which is why regulated sitting tenants can significantly affect a property's investment value. Succession rights also apply: on the tenant's death, the tenancy may pass to a spouse or civil partner, and in some circumstances to a family member who lived with the tenant for at least two years before death, though the successor typically receives an assured tenancy rather than a full regulated tenancy. Regulated tenancies are increasingly rare, no new ones have been granted since 1989, but those still in existence carry full Rent Act protection. Shelter England notes that these tenants sit entirely outside the Renters' Rights Act framework.

Assured tenancies and ASTs (1989–May 2026) - Tenancies created on or after 15 January 1989 are governed by the Housing Act 1988. From 1989 until 28 February 1997, landlords could grant full assured tenancies (not shorthold), which also give substantial security. From 1997 onwards, the default became the assured shorthold tenancy (AST). A sitting tenant on an AST rolling periodically after the fixed term has weaker security than a Rent Act tenant: possession was obtainable by the old Section 21 notice, subject to procedural compliance. The rent is the agreed contractual rent, reviewed by the statutory Section 13 process.

Post-Renters' Rights Act (from 1 May 2026) - All ASTs in the private rented sector in England automatically converted to assured periodic tenancies from 1 May 2026 under the Renters' Rights Act. Section 21 no-fault evictions are abolished. This means that all private tenants, including sitting tenants on former ASTs, now have grounds-based protection: the landlord must prove a specified statutory ground for possession to recover the property. In that sense, from May 2026 every private periodic tenant in England has sitting-tenant-like security against no-fault removal, regardless of length of residence. The distinction between a "sitting tenant" and any other periodic tenant has narrowed considerably.

Can a sitting tenant be evicted?

It depends on the tenancy type:

A regulated (Rent Act) sitting tenant can only be evicted if the landlord proves one of the specified grounds in the Rent Act 1977, most of which are discretionary and require the court to consider whether it is reasonable to grant possession. In practice, a Rent Act tenant who pays rent and does not breach the tenancy is extremely difficult to evict. Many landlords who have inherited Rent Act tenancies through purchase find that recovering vacant possession is effectively impossible without a specific ground such as the tenant sub-letting without consent, causing nuisance, or the landlord needing the property as their only residence.

An AST or assured periodic sitting tenant (post-May 2026) can be evicted only by proving a statutory ground, including rent arrears, anti-social behaviour, the landlord wishing to sell (Ground 1A), or the landlord or a family member wishing to move in (Ground 1), among others. No-fault eviction is no longer available.

How much does a sitting tenant devalue a property?

A property sold with a regulated (Rent Act) sitting tenant is typically discounted significantly, studies have cited figures ranging from 20–40% below vacant possession value in some London markets, though the actual discount depends on the registered fair rent relative to market rent, how long the tenancy has persisted, the likelihood of natural vacancy, and succession risk. The lower the registered rent and the stronger the security of tenure, the greater the discount.

A property sold with a modern assured periodic sitting tenant is typically discounted less, 5–15%, reflecting the restriction on immediate possession and the reduced buyer pool (most residential buyers cannot purchase with an active tenancy), but not the fundamental rent-level problem of a regulated tenancy.

Can a sitting tenant buy the property?

There is no legal right of first refusal for a sitting tenant in England under a private residential tenancy. A landlord is under no obligation to offer the property to the tenant before selling on the open market. Leaseholders of flats in multi-let buildings have different rights, including collective enfranchisement and the right of first refusal under the Landlord and Tenant Act 1987, but these do not apply to ordinary residential sitting tenants. A landlord may choose to offer the tenant the opportunity to buy, and some sitting tenants do negotiate a purchase, but this is a matter of commercial agreement rather than legal entitlement.

Sitting tenant: no contract

A tenant who continues in occupation after a fixed-term tenancy has ended without signing a new agreement has rolled onto a periodic (usually monthly) tenancy by statute. The absence of a written agreement does not remove their rights or make them easier to evict. They remain a fully protected assured (or, from May 2026, assured periodic) tenant with the same grounds-based protection as any other tenant. Landlords sometimes assume a "no contract" situation weakens the tenant's position, it does not.

Frequently asked questions

What is the difference between a sitting tenant and a tenant in situ?

In modern usage the terms are interchangeable and describe the same situation: a tenant who remains in a property when it is sold. "Tenant in situ" tends to appear in property listings, auction catalogues, and conveyancing; "sitting tenant" tends to appear in discussions of tenant rights and eviction. Historically, "sitting tenant" had a specific connotation of a Rent Act regulated tenant with very strong security, that original meaning still applies in some legal contexts, even though the phrase is now used more broadly.

How long before a tenant becomes a sitting tenant?

There is no minimum period, a tenant becomes a sitting tenant the moment the property is sold while they are in occupation. In the broader sense of a tenant who has stayed beyond a fixed term without a new contract, they become periodic from the day after the fixed term expires. The length of time in the property does not change the legal position for most modern tenancies, though it can be a signal that the tenancy may be a regulated Rent Act tenancy if the tenant has been in place since before 1989.

Can you evict a sitting tenant who does not have a contract?

Yes, but only through the proper statutory grounds process. A tenant without a current signed agreement is on a periodic tenancy by operation of law and has the same eviction protections as any other assured tenant. From May 2026, no-fault eviction is unavailable regardless of whether a contract exists. To recover possession, the landlord must serve a valid Section 8 notice citing an applicable ground, follow the correct notice period, and, if the tenant does not leave, obtain a court possession order.
