Deed of Assignment of Tenancy | s.15 Housing Act 1988

A deed of assignment of tenancy is a formal instrument that transfers the whole of a tenant's legal interest in a let to a new tenant. The assignor (the outgoing tenant) gives up the tenancy; the assignee (the incoming tenant) takes it over and becomes liable for the rent and the covenants from the assignment date forward. The landlord is almost always a party too, because their written consent is what makes the transfer lawful and because the deed is where that consent is recorded.

It helps to be precise about what assignment is not. Assignment is not subletting: a sublet creates a new, separate tenancy underneath the original one, and the head tenant stays liable to the landlord. Assignment is not a surrender and re-grant either, where the existing tenancy ends and a fresh one begins. With a true assignment, the same tenancy continues, on the same terms, simply with a different person holding it. That distinction carries real weight after the Renters' Rights Act 2025, because a surrender and re-grant would reset the tenant's twelve-month protected period and trigger fresh written-statement obligations, whereas a clean assignment preserves the continuity of the original assured periodic tenancy.

The instrument must be a deed, not a simple agreement, because the assignment of a tenancy is a disposition of a legal interest in land. A deed has to be in writing, make clear on its face that it is intended as a deed, and be validly executed and witnessed under section 1 of the Law of Property (Miscellaneous Provisions) Act 1989. Our rent guarantee deed for post-reform lettings follows the same execution formalities and is worth reviewing if a guarantor sits behind the incoming tenant.

Assignment of a residential tenancy in England and Wales sits on two statutory pillars. The first is section 15 of the Housing Act 1988, headed "Limited prohibition on assignment etc. without consent". It implies into every assured periodic tenancy a term that the tenant may not assign the tenancy, in whole or in part, except with the landlord's consent. Because almost all private residential lettings are now assured periodic tenancies following 1 May 2026, this implied prohibition is the default position for the overwhelming majority of tenants, whether or not their written agreement says anything about assignment at all.

The second pillar is the deliberate disapplication of the usual reasonableness safeguard. Section 15(2) states that section 19 of the Landlord and Tenant Act 1927, which would ordinarily prevent a landlord from unreasonably withholding consent to an assignment, does not apply to the term implied by section 15(1). The practical effect is striking: a landlord of an assured periodic tenancy may refuse consent to assign for any reason, or no reason at all, and the tenant has no statutory route to override that refusal. This is why a deed of assignment is only ever appropriate where the landlord is genuinely on board.

The Renters' Rights Act 2025 reshaped the surrounding landscape rather than the assignment rule itself. By abolishing fixed terms and converting all assured tenancies into periodic tenancies, it removed the old statutory periodic tenancy as a separate category, and Schedule 2 paragraph 27 of the Act trimmed the now-redundant wording in section 15(3) with effect from 1 May 2026. The substance survives intact: consent is still required, and section 19 of the 1927 Act is still excluded. Landlords should also remember that since reform they must give every named tenant the government Information Sheet and, for tenancies made after 1 May 2026, a written statement of key terms, points that bear on an incoming assignee. You can confirm the current statutory wording directly through the legislation.gov.uk entry for section 15 of the Housing Act 1988 on assignment without consent.

The classic trigger is a change of sharer in a joint tenancy. Three friends rent a house, one moves out, and a replacement moves in. Rather than end everyone's tenancy and grant a new one, the departing tenant assigns their interest with landlord consent, and the household continues seamlessly on the same agreement. Handled this way, the remaining tenants keep their accrued protected period and the landlord avoids re-papering the whole let.

Relationship breakdown is the next most common scenario. Where a couple holds a joint tenancy and one partner leaves, a deed of assignment can transfer the departing partner's share to the one who stays, cleanly removing the leaver from future rent liability. This is far tidier than informal arrangements where the leaver simply stops paying but remains legally on the hook. A business reason sits alongside these: an employer who holds a tenancy for staff accommodation may assign it to an incoming employee when roles change.

Two edge cases deserve a flag. First, assignment by operation of law on death or bankruptcy follows different rules, and a voluntary deed is not the right tool there. Second, where a guarantor stands behind the original tenant, assignment does not automatically carry the guarantee across, so a fresh guarantee is usually needed for the assignee, much like the protections set out in our tenant referencing and Right to Rent pack. Never let an assignee move in before the deed is executed and consent is documented, because retrofitting consent after the fact is where disputes start.

• The identification of the parties names the landlord, the outgoing tenant as assignor, and the incoming tenant as assignee in full, together with the address of the let and the date and type of the original tenancy. Vague drafting here is fatal: the deed must tie back precisely to the tenancy being assigned, otherwise it is unclear what interest has actually moved.
• The assignment of the tenancy is the operative clause, transferring the whole of the assignor's interest to the assignee from a stated date. It confirms the assignee takes the tenancy subject to and with the benefit of all the existing terms, so there is no doubt that the same assured periodic tenancy continues rather than a new one beginning.
• The landlord's consent is recorded expressly within the deed, satisfying the requirement under section 15 of the Housing Act 1988. Capturing consent in the same instrument removes any later argument that the landlord did not agree or agreed only on different terms.
• The release of the outgoing tenant discharges the assignor from liabilities accruing after the assignment date, while preserving the landlord's right to pursue arrears or breaches that predate it. This is the clause the leaving tenant cares about most, and it is frequently missing from improvised assignments.
• The assignee's covenants and acknowledgements confirm the incoming tenant has read the tenancy, accepts the rent and obligations, and has received the prescribed post-reform information. It is sensible to pair this with a refreshed deposit position, drawing on our deposit receipt and prescribed information template.

Assignment of an assured tenancy is governed by the same primary legislation across England and Wales, but the surrounding compliance picture diverges enough to matter. In England, the Renters' Rights Act 2025 regime applies in full: all lettings are assured periodic tenancies, the government Information Sheet must reach every named tenant, and an incoming assignee should be treated as a tenant for the purpose of Right to Rent immigration checks under the Immigration Act 2014. Skipping that check on an assignee is a common and expensive oversight, since the penalty regime bites per occupier. Confirm the position with our Assured Shorthold Tenancy agreement guidance, which explains how existing agreements converted on 1 May 2026.

In Wales, residential lettings fall outside the Housing Act 1988 framework entirely and are instead governed by the Renting Homes (Wales) Act 2016, which uses occupation contracts rather than assured tenancies. Assignment there follows the rules on transfer of an occupation contract, and the section 15 mechanism described above simply does not apply. If your property is in Wales, this England-and-Wales deed will need to be adapted to the occupation-contract model, and you should not assume the consent rules transfer across unchanged.

A point relevant across both jurisdictions concerns shared houses that are licensed as Houses in Multiple Occupation. Changing the identity of an occupier through assignment can affect the basis on which an HMO licence was granted, and some local authority licence conditions require the licence holder to notify the council of occupier changes. Before signing the deed, check whether the let is licensed and whether the assignment needs to be reported, because a breach of licence conditions carries its own penalties separate from anything in the tenancy.

You begin by confirming the most important fact: that the landlord actually consents to the assignment, because without it the deed has no foundation. From there you enter the details of the original tenancy, the property address, the start date and the type of agreement, so the deed locks onto the exact interest being transferred. The form then asks for the full names of the assignor and assignee, and prompts you to set the assignment date from which liability shifts.

Next you confirm whether the outgoing tenant is being fully released and whether any pre-assignment arrears are being preserved against them, which the template phrases for you so nothing is left ambiguous. You record the landlord's consent in the body of the deed and set out the assignee's acknowledgement of the tenancy terms and post-reform information. The final stage is execution: each party signs in the presence of an independent witness, because this is a deed and the Law of Property (Miscellaneous Provisions) Act 1989 execution formalities must be met. If a guarantor is involved, prepare their fresh documentation in parallel rather than after signing. For broader business transfers of property interests, our UK commercial and business document templates cover related ground.

The single most damaging error is treating consent as an afterthought. Because section 19 of the Landlord and Tenant Act 1927 is disapplied, a landlord's refusal cannot be challenged as unreasonable, so an assignment attempted without clear, documented consent is simply ineffective, and the would-be assignee acquires nothing. Almost as common is confusing assignment with subletting: people use a deed of assignment when they actually intend the original tenant to stay liable, which defeats the purpose and leaves the leaver exposed. A third recurring mistake is forgetting the release clause, so the outgoing tenant believes they have walked away while remaining contractually bound for rent that accrues after they have gone.

The remaining pitfalls cluster around formalities and compliance. Executing the document as an ordinary agreement rather than a properly witnessed deed undermines the whole transfer, since a disposition of a legal estate must be by deed. Landlords frequently overlook the Right to Rent check on the incoming assignee, treating them as somehow exempt because the tenancy already exists, which is wrong. And many parties forget that the assignment does not carry an existing guarantee across automatically, leaving the landlord unsecured the moment the original tenant departs. A short checklist before signing prevents nearly all of these, and our periodic tenancy notice to quit template is the right document if the answer turns out to be ending the tenancy rather than transferring it.
