Rent-to-rent in the UK: how it works, the contract, and staying compliant

The strategy itself is simple: rent a property from a landlord under one agreement, then sublet it under separate agreements, room by room or as a managed serviced let, for more in total rent than you pay the landlord. The margin comes from adding management, furnishing, or a room-by-room letting structure that the landlord was not set up to do themselves. What makes it legal or not has nothing to do with the strategy and everything to do with the paperwork underneath it.

The agreement is the whole game

A standard Assured Shorthold Tenancy (AST), the kind most landlords default to, typically prohibits subletting outright. Signing an AST and subletting anyway without the landlord's knowledge is the version of rent-to-rent that gives the strategy a bad name, and it exposes both the operator and the landlord to real risk. The version that works is built on a different kind of agreement, usually a company let or a management agreement, that explicitly grants the right to sublet, and it needs the landlord's informed, written consent stating that clearly.

Three consents, not one

• The landlord. Written consent to sublet, ideally naming the specific structure (subletting by room, or as serviced accommodation) rather than a vague general permission.
• The mortgage lender, if the property is mortgaged. Most standard buy-to-let mortgage terms do not permit the property to be sublet in this way, particularly not as an HMO. Operating without lender consent can put the landlord in breach of their mortgage terms, not just you.
• The freeholder, if the property is leasehold. Many leases restrict subletting or require the freeholder's consent for a change of use, separate from what the landlord themselves can agree to.

HMO licensing still applies

If you are subletting room by room to unrelated occupants, you are very likely operating a House in Multiple Occupation, and the same licensing rules apply as they would to any other HMO landlord. Mandatory licensing applies once a property is let to five or more people forming two or more households sharing facilities, and many councils run additional or selective licensing schemes that catch smaller properties too, so check with the local authority for the specific address rather than assuming. Operating an unlicensed HMO carries real penalties, and head landlords have been prosecuted where their rent-to-rent operator failed to hold the required licence, so this is not solely the operator's problem.

What the Renters' Rights Act changes

Section 21 (the "no fault" eviction route) was abolished for all tenancies in England from 1 May 2026 under the Renters' Rights Act 2025. For rent-to-rent specifically, this matters at the end of the head lease: sub-tenants on assured tenancies can generally only be removed through a Section 8 court process with a specified ground, not simply by giving notice, which changes how an operator plans for the end of an agreement with the landlord and needs to be built into the contract terms from the start, not treated as an afterthought.

Common questions

Is rent-to-rent legal in the UK?

Yes, when set up correctly: with the landlord's informed written consent to sublet, the mortgage lender's consent if the property is mortgaged, the freeholder's consent if leasehold, the right type of agreement (not a standard AST), and the correct HMO licence and safety certificates where they apply.

What type of contract do I need for rent-to-rent?

A standard Assured Shorthold Tenancy typically does not permit subletting. Rent-to-rent operators generally use a company let or management agreement that explicitly grants the right to sublet, with wording confirmed by a solicitor rather than a generic template.

Do I need an HMO licence for a rent-to-rent property?

If you are subletting room by room to unrelated occupants, you likely are operating an HMO, and mandatory licensing applies once five or more people from two or more households share facilities. Many councils also run additional or selective licensing for smaller properties, so check locally.

How does the Renters' Rights Act 2025 affect rent-to-rent?

Section 21 was abolished for all tenancies in England from 1 May 2026. Sub-tenants on assured tenancies can generally only be removed via a Section 8 court process with a specified ground, which changes how an operator needs to plan for the end of a rent-to-rent agreement with the landlord.
