Sublet Addendum Template for England and Wales

What is a Sublet Addendum?

The Sublet Addendum is essential when a tenant wishes to rent out all or part of their leased property to another party while maintaining their original lease agreement. Used extensively in England and Wales, this document provides necessary legal protection and clarity for all parties involved. It typically includes details about rent payments, maintenance responsibilities, duration of the sublease, and specific conditions set by the original landlord. The addendum ensures compliance with local housing laws and regulations while preserving the original lease's integrity.

About the Sublet Addendum

A Sublet Addendum is an addendum to your tenancy agreement that lets you rent out your leased property to another party while keeping your original tenancy intact. Under England and Wales law, this addendum creates a formal framework that protects all parties in a subletting arrangement and keeps it consistent with housing legislation. You add it to the existing contract, both sides sign it, and the original tenancy keeps running unchanged alongside it.

What is an addendum to a tenancy agreement?

An addendum is a short document that changes or adds to an existing tenancy agreement without rewriting the whole contract. It sits alongside the original and both documents are read together once signed. A Sublet Addendum is the specific type used to permit and regulate subletting: it names the subtenant, sets the rent they pay, fixes the dates, and records the landlord's written consent. If you need to change other terms rather than add subletting, a general tenancy agreement variation may be a better fit. The same addendum lease approach applies to commercial and residential leases alike, with the lease addendum attached to and read with the original.

When do you need this document?

You need a Sublet Addendum whenever you want to sublet part or all of your rental property to another tenant. This commonly arises when you're temporarily relocating for work, studying abroad, or need additional income to cover rent. The document helps in student accommodation where one tenant leaves mid-term, or when professionals take extended business trips but want to keep their tenancy. Without proper documentation, subletting can breach your original lease terms and put your tenancy at risk.

How do I add a sublet addendum to my tenancy?

First, read your original tenancy agreement to confirm whether subletting is allowed and what consent the landlord expects. Next, ask the landlord in writing and get their permission before anyone moves in, since most tenancies prohibit subletting without consent. Then complete the addendum with the subtenant's details, the rent, the dates, and the allocation of maintenance and management responsibilities. Finally, all parties sign and date it, and each keeps a copy. The signed addendum then forms part of your tenancy records.

What to include in a tenancy agreement addendum

A clear lease agreement addendum keeps every term in one place so the agreement between tenant, subtenant and landlord reads consistently. Cover these points:

• Names and contact details of the original tenant, the subtenant and the landlord
• The rent the subtenant pays, when it falls due, and whether it goes to you or the landlord
• The start and end dates, and any notice period
• How maintenance, repairs and property management duties are allocated
• The landlord's written consent to the subletting
• What happens to the subtenant if the original tenancy ends early
• A reference to the original tenancy so both documents are read together

Key legal considerations

Written consent from your landlord comes first, as most tenancy agreements prohibit subletting without permission. The addendum should define the relationship between all parties and confirm that you remain primarily liable to the original landlord for rent and property obligations. Payment terms must specify whether the subtenant pays you directly or the landlord, and maintenance and property management duties should be clearly allocated. The document must also address what happens if the original tenancy ends early, so the subtenant understands their position. Insurance matters too, as standard contents cover may not extend to subletting.

Legal requirements in England and Wales

Under the Housing Act 1988, a subletting arrangement must follow Assured Shorthold Tenancy rules if you are creating a new tenancy. The Tenant Fees Act 2019 limits the fees charged to subtenants, and you cannot profit from the security deposit. The addendum should keep the property in line with the Landlord and Tenant Act 1985 on repair responsibilities and housing standards. If your property becomes a House in Multiple Occupation through subletting, local authority licensing rules may apply under the Housing Act 2004. The Consumer Rights Act 2015 asks that all terms are fair and transparent. You should also give the subtenant prescribed information about the tenancy and any relevant certificates, just as the original landlord gave to you.

Sublet Addendum vs new tenancy agreement

Can a landlord refuse subletting?

Yes. Many tenancies either ban subletting outright or require the landlord's consent, and the landlord can decline consent on reasonable grounds. Always check the original agreement and get written sign-off before signing any addendum. If the landlord agrees, record that consent in the addendum itself so there is a single document showing the terms, the parties, and the permission. Keeping the landlord's contact details and approval on file protects the original tenant if questions arise later.
