Rent Increases: Your Rights and How to Challenge Them

If you are within the fixed term of your tenancy (for example, a 12-month assured shorthold tenancy), your landlord cannot increase the rent unless your tenancy agreement contains a rent review clause. If there is no such clause, the rent remains at the agreed amount for the entire fixed term.

A rent review clause might say something like: "The landlord may increase the rent on the anniversary of the tenancy start date by giving 1 month's written notice." If your agreement contains a clause like this, the landlord can increase the rent in accordance with the clause. However, the increase must still be reasonable — an excessive increase could potentially be challenged.

If the landlord asks you to agree to a rent increase during a fixed term and there is no review clause, you are under no obligation to agree. You cannot be evicted for refusing a rent increase during a fixed term.

After a fixed-term tenancy expires, most tenancies become periodic (rolling month-to-month or week-to-week). For periodic assured shorthold tenancies, the landlord can propose a rent increase using a Section 13 notice (prescribed form). The rules are:

• The notice must be in the prescribed form (currently Form 4)
• For a monthly tenancy: at least 1 month's notice
• For a yearly tenancy: at least 6 months' notice
• The rent can only be increased once per year (not more frequently unless the tenancy agreement allows it)
• The proposed new rent must take effect at the beginning of a new period of the tenancy

If the landlord does not use the correct form or does not give sufficient notice, the rent increase is not valid and you should continue paying the current rent. Paying the increased amount — even once — could be treated as acceptance of the new rent, so be careful about making payments at the higher rate if you intend to challenge.

If you believe the proposed rent increase is above the market rate, you can refer it to the First-tier Tribunal (Property Chamber). The process is:

1. Apply before the effective date: You must refer the increase to the tribunal before the date the new rent would take effect. If you miss this deadline, the increase stands.
2. The tribunal's assessment: The tribunal determines the rent at which the property might reasonably be expected to be let on the open market by a willing landlord to a willing tenant. They consider comparable rental evidence for similar properties in the area.
3. The tribunal ignores: Any improvements you have made to the property (you should not be penalised for improving it), and any reduction in the value of the property due to your failure to look after it properly.
4. The outcome: The tribunal sets the rent at what it considers the market rate. This could be lower than the landlord's proposal, the same as the current rent, or in rare cases even higher than what the landlord proposed (though this is uncommon). The tribunal's decision is binding.

Applying to the tribunal is free and you do not need a solicitor, though you can have one if you wish. The process usually involves written submissions and comparable evidence rather than a formal hearing.

"Market rent" is the rent that a willing tenant would pay for the property in its current condition, on the open market, without any premium for sitting tenant security. The tribunal considers:

• Comparable properties: What similar properties in the same area are renting for. Size, condition, location, and amenities are all relevant. Online listings (Rightmove, Zoopla, OpenRent) can provide evidence of comparable rents.
• The condition of the property: A property in poor condition should command a lower rent than a well-maintained one. If your landlord has neglected repairs, this should be reflected in the market rent assessment.
• The terms of the tenancy: Any unusual terms that benefit or disadvantage the tenant (for example, a tenancy that includes bills would justify a higher rent than one that does not).

It is not relevant what you can afford, what your housing benefit covers, or what the landlord's mortgage costs are. The tribunal looks solely at what the open market would bear for that property.

If you plan to challenge, gather evidence: screenshot comparable listings, note the size, location, and condition of the comparator properties, and be prepared to explain why they are genuinely comparable to yours.

• By agreement: You and your landlord can mutually agree to a rent change at any time. Get any agreement in writing. You are under no obligation to agree.
• New tenancy agreement: If the landlord offers a new fixed-term tenancy at a higher rent, you can negotiate the rent before signing. If you do not agree, the existing tenancy continues as a periodic tenancy at the current rent.
• Social housing: If you are a social tenant (council or housing association), rent increases follow different rules — usually linked to a government formula (CPI + 1%) and subject to the Rent Standard set by the Regulator of Social Housing.

A landlord cannot use a rent increase as a tool to punish you for exercising your legal rights. While there is no explicit statutory ban on retaliatory rent increases (unlike retaliatory eviction), a tribunal assessing a Section 13 increase looks only at market evidence — so an increase motivated by spite would only succeed if it genuinely reflects the market rate.

If you have recently complained about disrepair, raised a grievance, or asserted a legal right, and the landlord immediately proposes a large rent increase, this context may be relevant. Document the timeline of your complaint and the rent increase proposal.

Under the proposed Renters' Rights Bill, tenants would gain additional rights to challenge above-market rent increases, though the details depend on the final form of the legislation.
