Make Changes to a Tenancy Agreement by using an Addendum

An Addendum is a legal document which sets out an additional legal agreement between a landlord and tenant to be read in conjuction with the main Tenancy Agreement.

Changing a Tenancy Agreement

A tenancy agreement cannot usually be changed unless both parties agree to the changes.

If both parties agree, the change should be recorded in writing either by drawing up a new tenancy agreement or by amending the existing agreement. There are many reasons for changing or updating a tenancy agreement such as :

    • The landlord wishes to increase the rent.
    • The landlord wishes to change the specific terms of the agreement e.g. allowing a guide dog for a disabled tenant.
    • The tenant wishes to transfer their tenancy to a member of their household who has lived with them for more than one year.
    • The tenant wishes to share the responsibilities of the tenancy by having a joint tenancy.

Changes can be agreed verbally but this can lead to problems, as changes without written documentation are harder to prove. In this case, evidence of the change of agreement will usually rely on the fact that both parties accepted the change. For example, this could be accepting a variation to the rent received/paid. Witnesses to the new agreement being accepted can also act as proof of the changes.

Important: If you are a landlord and need a Tenancy Agreement you may also need to either use a Section 8 Notice to Quit, Section 13, New Tenancy Agreement or a Section 21 Notice. To make life a bit easier for you, to help our landlords (and agents) in this situation we have a bundle called the Landlord Saver Pack that includes both of these notices plus a new Tenancy Agreement together with great Guidance notes. It will also save you about £65.  You can get it here

It is always safer to ensure that any changes in the rental agreement are recorded in the form of a written document.

Landlords are required to make reasonable efforts to change a tenancy agreement if failing to do so would impinge on the tenant's right to not be discriminated upon based on sex, disability, religion or sexuality.

For example, if a tenant becomes disabled, the landlord is expected to amend the tenancy agreement to allow the tenant to make disability-related improvements to the property.

Before signing a tenancy agreement, it is important that the tenant understands the vocabulary and terms used. If necessary the tenant should ask for an explanation of any unfamiliar property terms before agreeing to the tenancy and signing the agreement.
