Rent Increase Letter Template for England and Wales

A Rent Increase Letter is a legal document that lets landlords in England & Wales formally notify a tenant of a proposed change to their rent. You must follow strict legal procedures when raising rent, because a notice that does not meet statutory requirements can be invalid and delay the increase. The letter works as both formal notification and a written record, so your rent increase follows the proper legal route.

What is a rent increase letter?

It is a written notice from a landlord to a tenant that states the current rent, the new rent, and the date the increase takes effect. For an assured periodic tenancy it takes the form of a Section 13 notice on the prescribed Form 4. The letter is the start of the formal process, and it gives the tenant the information they need to check the figure and decide whether to accept it or challenge it.

When do you need this document?

You need a Rent Increase Letter whenever you want to raise the rent on an existing tenancy in England & Wales. This applies to periodic tenancies where you are not bound by a fixed-term agreement specifying rent amounts. You use this document for an assured periodic tenancy, which since 1 May 2026 is the standard form of residential letting in England. The letter is particularly useful when market conditions have changed, property improvements have been made, or when your current rent falls below comparable homes in the area. Fixed-term assured tenancies no longer exist in England, so the old question of raising rent part-way through a term does not arise. A rent increase on an assured periodic tenancy follows the statutory procedure.

What content must the letter include?

The content of a valid notice is fixed by statute, so the letter has to carry a specific set of details rather than a free-form message. A compliant rent increase letter includes:

• The names of the landlord and tenant and the address of the let property.
• The current rent and the proposed new rent.
• The date the new rent takes effect.
• A statement of the tenant's right to refer the proposed rent to the First-tier Tribunal.
• The landlord's name, address and contact details so the tenant can reply.

Leaving any of these out can make the notice invalid, so check the content against the prescribed Form 4 before you serve it.

What is a rent review clause and how does it differ?

A rent review clause is a term written into a tenancy agreement that sets out in advance how and when rent can be reviewed, for example by linking it to an index or to market rent at fixed dates. A Section 13 rent increase works differently. Where a residential assured periodic tenancy has no workable rent review mechanism, the statutory Section 13 route applies, and you serve the formal notice rather than relying on a contractual rent review. Commercial and longer residential agreements more often contain a dedicated rent review clause, and you can set those terms up front in a lease agreement.

Key legal considerations

Several legal factors govern rent increases in England & Wales. You can only increase rent once per year for the same tenant, regardless of how many separate notices you might want to serve. The proposed rent must be reasonable and reflect current market rates for similar homes in your area. Your tenant has the right to challenge an increase they think is unfair through the First-tier Tribunal, which can determine a fair market rent. You must give specific information including the current rent, the proposed new rent, and a clear effective date. The notice must be served correctly, either by hand delivery, registered post, or another prescribed method. Failing to follow the proper procedure can make the notice invalid.

How do you serve a rent increase letter correctly?

Fill in the current rent, the new rent, and the date the increase starts, then serve the completed Form 4 on the tenant using a method you can evidence. Give at least one month's notice for a periodic tenancy, extending to one full rental period if rent is paid less frequently than monthly. Keep proof of service and keep your contact details on the letter so the tenant can reply or ask questions. If the tenant does not agree, they can refer the proposed rent to the First-tier Tribunal before the start date.

How much notice does a landlord have to give to increase rent?

Timing is one of the most common reasons a notice fails. For an assured periodic tenancy, the landlord has to give the tenant at least one month's notice before the new rent takes effect, and that period extends to one full rental period where rent is paid less frequently than monthly. The notice period runs from the date the tenant actually receives the letter, so build in time for postal delivery when you set the effective date. A landlord can increase rent this way no more than once in any twelve-month period.

Legal requirements in England & Wales

Under the Housing Act 1988 and Section 13 notice requirements, you must give minimum notice periods that vary by tenancy type. For periodic tenancies, you need at least one month's notice, though this extends to one rental period if rent is paid less frequently than monthly. You should use the prescribed Form 4 for formal Section 13 notices to help ensure compliance. The Landlord and Tenant Act 1985 requires that your notice includes specific details about the property, current rent, proposed new rent, and effective date. The Tenant Fees Act 2019 also affects rent increase procedures by restricting additional fees you can charge during the process. Your notice must clearly state the tenant's rights, including their ability to challenge the increase and seek tribunal determination if they believe the proposed rent is unreasonable.
