Overview
From 2026, under the Renters' Rights Act 2025, landlords can generally only increase rent once every 12 months. All rent increases must be communicated via a formal Rent Increase Notice, specifying the new rent, the effective date, and providing at least two months' notice. Tenants retain the right to challenge proposed increases they deem unreasonable at the First-tier Tribunal, and landlords must be able to justify the new rent. The previous fixed-term and periodic tenancy distinctions for rent review largely disappear, moving towards a more standardised annual review process.
Why it matters
Non-compliant rent increases can be legally unenforceable, meaning you may be unable to recover the intended higher rent. Incorrect notice procedures can lead to delays in implementing rent changes, tribunal challenges, and potentially adverse rulings against you. Understanding the new framework ensures your income stream is secure, your tenancies are compliant, and you avoid costly legal disputes and administrative burdens.
Legal requirements
- Rent can generally only be increased once every 12 months for any given tenancy.
- A formal Rent Increase Notice must be served to the tenant, providing full details of the proposed increase.
- The notice period for a rent increase must be at least two months, allowing the tenant time to consider the proposal or challenge it.
- The notice must specify the current rent, the proposed new rent, and the date from which the new rent will apply.
- If the tenant disputes the increase, they have the right to refer the matter to the First-tier Tribunal (Property Chamber) before the new rent takes effect.
- Landlords must be able to demonstrate that the proposed rent is broadly in line with local market rates for similar properties.
- Any agreement for a rent increase must be made in writing, either through a formal notice or a new tenancy agreement reflecting the updated rent.
- The rent increase must not be seen as retaliatory, particularly following a tenant's legitimate complaint about property conditions.
Common mistakes
- Attempting to increase rent more frequently than every 12 months, which is generally not permitted under the new rules.
- Failing to provide the minimum two months' notice period for a rent increase, rendering the notice invalid.
- Communicating a rent increase informally, such as via email or text message, without serving a formal Rent Increase Notice.
- Proposing a rent increase that is significantly above local market rates without clear justification, inviting tribunal challenge.
- Ignoring a tenant's right to challenge the rent increase at the First-tier Tribunal, leading to potential legal complications.
- Increasing rent immediately after a tenant has made a complaint about repairs, which could be deemed a retaliatory eviction attempt.
- Neglecting to keep clear records of rent increase notices served and any tenant responses or agreements.
- Assuming a tenant's continued payment of the increased rent automatically validates an improperly served notice.
Practical guidance
- Review your tenancy agreements annually to identify appropriate times for a rent review, aligning with the 12-month rule.
- Research local market rates thoroughly to ensure any proposed rent increase is reasonable and justifiable.
- Use an official Rent Increase Notice form or a professional template to ensure all required information is included.
- Serve the Rent Increase Notice with at least two full months' notice, calculating the dates carefully.
- Deliver the notice by a method that allows for proof of service, such as recorded delivery or a hand-delivery witnessed by a third party.
- Be prepared to engage in discussion with your tenant about the proposed increase and address any concerns they may have.
- If the tenant challenges the increase, compile evidence of local market rents to present to the First-tier Tribunal.
- Consider offering a new fixed-term tenancy agreement at the increased rent if both parties agree, providing security.
- Maintain a comprehensive paper trail of all communications, notices, and agreements related to rent increases.
- Familiarise yourself with the tribunal process in case a tenant refers a rent increase for determination.
The new 12-month rule and notice period
The Renters' Rights Act 2025 significantly streamlines rent review periods. For most tenancies, landlords will generally be able to increase rent no more than once every 12 months. This replaces the previous variations that depended on whether a tenancy was fixed-term or statutory periodic. The aim is to provide tenants with greater financial predictability. When a landlord wishes to increase the rent, they must serve a formal Rent Increase Notice, which specifies the current rent, the proposed new rent, and the date the new rent will take effect. Crucially, this notice must be served at least two months before the proposed effective date of the increase. Failure to adhere to this minimum notice period will render the increase invalid, and you will not be able to enforce the higher rent from the intended date. It is essential to calculate these dates accurately to avoid procedural errors.
The Rent Increase Notice requirements
A valid Rent Increase Notice is more than just a casual conversation or an email. It must be a formal, written document. While there isn't a single prescribed government form, the notice must clearly state the existing rent amount, the proposed new rent, and the exact date from which this new rent will become payable. It must also inform the tenant of their right to challenge the increase at the First-tier Tribunal (Property Chamber) before the new rent takes effect. Landlords should use a notice that incorporates all these elements. Serving such a notice correctly is fundamental to implementing any rent increase. Without a properly issued notice, any attempt to raise the rent will likely be unenforceable. Keeping proof of service is also paramount, as disputes over whether a notice was received are common.
Tenant's right to challenge and tribunal process
A key protection for tenants under the Renters' Rights Act 2025 is their right to challenge a proposed rent increase if they believe it is unreasonable. If a tenant refers the matter to the First-tier Tribunal before the effective date stated in the notice, the proposed increase is paused until the Tribunal makes a decision. The Tribunal will assess whether the proposed rent is in line with market rents for similar properties in the local area. Landlords should be prepared to provide evidence to justify their proposed increase, such as comparable rents for similar properties advertised locally. If the Tribunal deems the proposed rent unreasonable, it has the power to set a different, fair market rent or even uphold the existing rent. Both landlords and tenants are bound by the Tribunal's decision. This process underscores the importance of proposing fair and justifiable rent increases.
Scotland: Rent caps and different tribunals
The rules for rent increases differ significantly in Scotland, governed by the Private Housing (Tenancies) (Scotland) Act 2016. For private residential tenancies, rent can generally only be increased once every 12 months. A formal 'rent increase notice to tenant' must be given, providing at least three months' notice. If a tenant believes the increase is unreasonable, they can apply to a Rent Officer for adjudication. The Rent Officer will determine a 'fair rent', considering local market rates. Currently, there are emergency rent caps in place, potentially limiting increases even if the market rate is higher. These caps are subject to ongoing review. Landlords in Scotland must therefore be particularly aware of the specific notice periods, the role of the Rent Officer, and any prevailing rent cap legislation, which can change.
Wales and Northern Ireland: Distinct legislation
In Wales, the Renting Homes (Wales) Act 2022 fundamentally changed housing law from December 2022. For standard occupation contracts, a landlord can generally only increase rent once every 12 months. They must serve a 'rent review notice' at least two months before the increase takes effect. If a tenant believes the increase is unfair, they can refer it to the Rent Assessment Committee. Northern Ireland also has its own distinct legislation, primarily the Private Tenancies (Northern Ireland) Order 2006. Rent can only be increased once every 12 months. The landlord must give the tenant at least four weeks' notice in writing of a proposed rent increase. Tenants can refer a proposed increase to a Rent Officer if they believe it is too high, and the Rent Officer will determine a fair rent. Landlords in all devolved nations must consult the specific legislation for their region.
Frequently asked questions
How often can I increase the rent under the Renters' Rights Act 2025?
Under the Renters' Rights Act 2025, landlords can generally increase the rent for a property no more than once every 12 months. This applies to ongoing tenancies, irrespective of whether they were previously categorised as fixed-term or periodic. This change aims to provide tenants with greater stability and prevent overly frequent rent adjustments. Always ensure you adhere to the specified notice periods when proposing an increase.
What happens if a tenant challenges my rent increase at the Tribunal?
If a tenant challenges your proposed rent increase at the First-tier Tribunal (Property Chamber) before the effective date, the increase will be paused. The Tribunal will then assess the market rent for your property by considering comparable local properties. They may either uphold your proposed increase, set a lower 'market rent', or decide that the current rent should remain. Both parties are bound by the Tribunal's decision, so be prepared with evidence to support your proposed rent.
Can I agree a rent increase directly with my tenant without a formal notice?
While it is always best practice to use a formal Rent Increase Notice, you can technically agree a rent increase with your tenant through a mutual written agreement, such as a new tenancy agreement or an addendum. However, this must be genuinely agreed by both parties, without coercion. If there is no such agreement, or if the tenant wishes to dispute it, a formal notice process is required for the increase to be legally binding. It is generally safer and more transparent to serve a proper notice.
Does the Renters' Rights Act 2025 allow for rent caps?
The Renters' Rights Act 2025 itself does not introduce universal rent caps across England. It focuses on fair and transparent rent increases, giving tenants the right to challenge unreasonable proposals at the First-tier Tribunal. However, devolved nations like Scotland have previously implemented emergency rent caps. It is crucial for landlords to stay informed about any specific regional legislation or emergency measures that may introduce temporary or permanent rent controls in their jurisdiction, as these can change.
What is considered 'unreasonable' for a rent increase?
An 'unreasonable' rent increase is typically one that significantly exceeds the prevailing market rates for similar properties in the local area. When a tenant challenges an increase at the First-tier Tribunal, they will assess whether the proposed rent is broadly in line with comparable rents. Factors such as property size, condition, location, and amenities are considered. Landlords must be able to justify their proposed rent with evidence of local market comparables to avoid it being deemed unreasonable.
Do I need to issue a new tenancy agreement with every rent increase?
No, you do not necessarily need to issue a brand-new tenancy agreement every time you increase the rent. A properly served Rent Increase Notice, which is not successfully challenged by the tenant, is sufficient to legally change the rent payable under the existing tenancy. However, some landlords choose to issue a new agreement or an addendum to clearly reflect the updated rent and other terms, which can be beneficial for clarity and record-keeping.
What if my tenant pays the new rent without disputing it?
If your tenant begins paying the new, increased rent without raising an objection or referring the matter to the First-tier Tribunal before the effective date, this generally signifies their acceptance of the new rent. In such a scenario, the new rent becomes the legally agreed rent for the tenancy. It is still advisable to ensure the initial Rent Increase Notice was served correctly and that you have proof of delivery for your records, in case any future dispute arises.
