Changing the Terms (Not Rent)

From 1 May 2026, most private rented sector assured tenancies in England begin as periodic tenancies. A landlord usually cannot change the tenancy terms just by telling the tenant that the terms have changed. If the terms are to change, the usual position is that the tenant must agree.

Any agreed change should be put in writing. If it is a minor point, a brief written variation signed by both parties will often suffice. If the change is more substantial, it may be better to enter into a new tenancy agreement in the current assured periodic form.

If the landlord wants to change the rent, the statutory rent-increase procedure must be followed instead.

Consent is different from changing the tenancy

Quite often, there is no need to change the tenancy terms at all. Many tenancy agreements already say that certain things are not allowed unless the landlord gives prior written consent.

In those cases, the landlord is not varying the agreement. They are simply deciding whether to give consent under an existing term.

Taking in a lodger

Many tenancy agreements say that the tenant must not sublet or take in a lodger without the landlord’s written consent.

If the agreement permits, the landlord can provide written permission without changing the tenancy terms. The permission should say clearly what is allowed and on what basis.

If the arrangement is likely to continue in the long term, or would amount to a more permanent change in occupation, it is usually better to consider a new tenancy and, if needed, seek advice rather than deal with it informally.

Alterations and redecoration

Tenancy agreements often say that the tenant must not redecorate, install fixtures, or make alterations without the landlord’s written consent.

Again, that usually does not mean the tenancy terms need to be changed. The landlord can simply give or refuse consent under the existing clause.

If consent is given, it should set out exactly what works are permitted and any conditions, for example:

• using suitably qualified contractors
• complying with planning rules or building regulations where relevant
• making good any damage
• returning the property to its original condition at the end of the tenancy, if required

Giving consent

Any consent should be in writing. If the parties have been communicating by email, consent given by email will usually be acceptable.

The consent should be clear about:

• what is being agreed
• whether the consent is personal to the current tenant
• any conditions attached to it
• whether it can be withdrawn if those conditions are broken

A clear written record makes later disputes less likely.
