Is there a limit on how much a landlord can increase rent?

There is no statutory cap on rent increases for private tenancies in England. However, any increase must be fair and realistic — meaning it should reflect the market rent for similar properties in the local area. If the increase is unreasonable, you can challenge it through the First-tier Tribunal (Property Chamber).

How must a landlord notify me of a rent increase?

For a periodic tenancy, the landlord must use a Section 13 notice (Form 4) to propose a rent increase, giving at least one month's notice for a monthly tenancy (or one rental period for longer periods). For a fixed-term tenancy, the rent can only be increased if the tenancy agreement includes a rent review clause, or if both parties agree to the increase in writing.

Can I refuse a rent increase?

Yes. If the landlord uses a Section 13 notice, you can challenge the increase by applying to the First-tier Tribunal (Property Chamber) before the proposed increase takes effect. The Tribunal will determine the market rent for the property. If the proposed increase is above market rent, the Tribunal will set a lower rent. If you simply refuse without applying to the Tribunal, the increase will take effect and you may fall into arrears.

How often can a landlord increase the rent?

In a periodic tenancy, the landlord can only increase the rent once every 12 months using a Section 13 notice. In a fixed-term tenancy, the rent review clause in the agreement will specify how often increases can occur. If there is no clause, the landlord cannot increase the rent during the fixed term without your agreement.

Can the landlord increase rent to force me out?

If a landlord proposes an unreasonably high rent increase with the intention of forcing you to leave, this could be challenged at the Tribunal as not reflecting the market rent. However, there is no specific 'retaliatory rent increase' law — the protection is that the increase must be fair and in line with market rates.

How Much Can a Landlord Increase Rent? UK Rules 2026

Your landlord wants to increase your rent — but how much can they actually charge? In England, there is no statutory cap on rent increases for private tenancies, but the increase must be fair, realistic, and follow the correct legal procedure. If the proposed increase is unreasonable, you have the right to challenge it. Here is everything you need to know about rent increases in 2026.

The Basic Rules

How a landlord can increase your rent depends on what type of tenancy you have:

Fixed-term tenancy (still within the fixed term): The rent can only be increased if the tenancy agreement includes a rent review clause that specifies when and how increases can occur. If there is no such clause, the landlord cannot increase the rent during the fixed term unless you agree to it voluntarily in writing. If you do not agree, the landlord must wait until the fixed term ends.
Periodic tenancy (rolling from month to month, or after the fixed term has ended): The landlord can propose a rent increase using a Section 13 notice (under the Housing Act 1988). This requires giving you at least one month's notice for a monthly tenancy, or one full rental period for longer tenancy periods. The increase can only happen once every 12 months.

Step-by-Step: What to Do If Your Landlord Proposes a Rent Increase

Check the form of the notice. For periodic tenancies, the landlord must use a valid Section 13 notice (Form 4 or equivalent). A casual email or text message saying "rent is going up next month" is not a valid Section 13 notice. If you are in a fixed term, check your tenancy agreement for a rent review clause.
Check the notice period. The notice must give at least one month for a monthly tenancy. If the notice period is shorter, the notice is invalid.
Research market rents. Before deciding whether to accept or challenge the increase, look at what similar properties in your area are renting for. Check sites like Rightmove, Zoopla, and OpenRent, and look at the Office for National Statistics (ONS) private rental index for your region.
Try to negotiate. If you think the increase is too high but you want to stay, contact the landlord or agent in writing. Present evidence of market rents in the area and propose a counter-offer. Many landlords prefer to keep a good tenant at a slightly lower rent than risk a void period and re-letting costs.
Challenge through the First-tier Tribunal (Property Chamber). If negotiation fails and you believe the increase is above market rent, you can apply to the Tribunal. You must apply before the date the increase is due to take effect. The Tribunal will assess the market rent and set the rent at that level. If the market rent is actually higher than the landlord proposed, the Tribunal can set a higher rent — so do your research carefully.

How the Tribunal Calculates Market Rent

The First-tier Tribunal will consider:

The rent charged for similar properties in the local area (comparables)
The age, character, and location of the property
The condition and state of repair of the property
Any furniture or services provided by the landlord
Any disrepair or outstanding repair issues

The Tribunal will disregard any improvements made by the tenant at their own expense, and will disregard the personal circumstances of either party — it is purely a market rent assessment.

What If You Cannot Afford the Increase?

If the increase is fair (in line with market rent) but you cannot afford it, the landlord is under no obligation to keep the rent lower. You can negotiate, but if the landlord insists and you cannot pay, you may need to consider moving. Check if you are eligible for Universal Credit housing costs or discretionary housing payments from your local council to help with the shortfall. Your local council's housing options team may also be able to advise.

What If the Landlord Tries to Evict You Instead?

Some landlords may respond to a rent increase refusal by serving a Section 21 eviction notice. If you are within the fixed term, they cannot do this until the term ends (unless there is a valid break clause). If you are in a periodic tenancy, they can serve a Section 21 — but they must still comply with all the requirements (deposit protection, gas safety, EPC, etc.). A retaliatory Section 21 served because you challenged a rent increase at the Tribunal does not automatically become invalid, but the timing may be relevant if you also complained about repairs.

Jurisdiction: England (and Wales)

Section 13 of the Housing Act 1988 and the First-tier Tribunal (Property Chamber) apply in England. In Wales, rent increases for occupation contracts under the Renting Homes (Wales) Act 2016 have their own procedures, and challenges are heard by the Rent Assessment Committee. Scotland and Northern Ireland each have their own separate rent increase rules.

FAQ

What if my tenancy agreement says the rent will increase by a fixed percentage each year?

If your fixed-term tenancy agreement contains a rent review clause stating a specific increase (for example, "the rent will increase by 3% on the anniversary of the tenancy"), this is enforceable as a contractual term. You agreed to it when you signed the tenancy. You cannot challenge this through the Tribunal during the fixed term. However, if the clause is unfair under the Consumer Rights Act 2015 (for example, it is hidden in small print or disproportionately one-sided), it may be challengeable.

Can a landlord increase rent during a fixed-term tenancy without a rent review clause?

No. In the absence of a rent review clause, the landlord cannot unilaterally increase the rent during the fixed term. They must either wait until the fixed term ends and the tenancy becomes periodic, or negotiate a voluntary agreement with you (which you are free to refuse).

What happens if I continue paying the old rent after a valid increase?

If the landlord has used a valid Section 13 notice and you have not challenged it at the Tribunal, the increase takes effect on the specified date. If you continue paying the old amount, you will fall into arrears. The landlord can then use the arrears as grounds for a Section 8 eviction (Ground 8 or 10). Always pay the increased rent if you have not formally challenged it — even if you are disputing it — to avoid arrears.

Do rent controls exist anywhere in the UK?

Scotland has rent control measures in place through the Cost of Living (Tenant Protection) (Scotland) Act 2022, which has been extended and modified. In England and Wales, there are no general rent controls for private tenancies, though some local authorities have introduced selective licensing schemes with additional conditions. Always check your local council's website for any local schemes.
