After the rules tightened for landlords and protection increased for tenants, the question all landlords have been asking is: how much can a landlord raise rent in the UK in 2026? Although there is no fixed percentage cap in England, the process, timing, and justification behind a rent increase matter more than ever.
In 2026, landlords must be careful not only about how much they increase rent by, but also how they do it. Incorrect increases can be challenged, delayed, or declared invalid.
Is There a Legal Limit on Rent Increases in the UK in 2026?
In England, there is still no set legal percentage limit on rent increases. A landlord can raise rent by any amount provided it reflects the market rate and follows the correct legal process.
However, this does not mean landlords can increase rent freely. Tenants have stronger rights to challenge increases they believe are unfair or above market value, and tribunals will assess whether the proposed rent is reasonable.
It’s also important to note that rules differ across the UK. Scotland and Wales operate under different systems, so this guidance focuses on England, which is where most landlords search when asking how much rent can be raised in the UK.

How Often Can a Landlord Increase Rent?
In most cases, a landlord can only increase rent once every 12 months.
If a landlord uses the statutory route to increase rent, they must wait a full year between increases. Attempting to raise rent more frequently can make the increase invalid and open to challenge.
This annual limit is especially important in 2026, as rent review clauses are no longer relied upon in the same way as before.
How Can a Landlord Increase Rent Legally in 2026?
There are three lawful ways to increase rent in England:
1. Agreement with the Tenant
A landlord and tenant can agree to a rent increase at any time, provided both parties consent. This is often the easiest route, but the tenant is not obliged to agree.
2. Rent Review Clauses
From May 2026, automatic rent increase clauses will no longer apply for ongoing tenancies. This means landlords can no longer rely on built-in rent uplift clauses alone to raise rent.
3. Section 13 Notice (Form 4)
For most tenancies in 2026, landlords must use a Section 13 rent increase notice, served on the correct government form. This route can only be used once per year and must give the correct notice period.
What Changed for Rent Increases After May 2026?
One of the most important updates affecting how much a landlord can raise rent in the UK in 2026 is the removal of automatic rent increases.
From May 2026 onwards:
-
Rent increases must follow the statutory process
-
Section 13 notices become the main legal route
-
Landlords must justify increases using market evidence
-
Errors in notices are more likely to be challenged
This shift places greater responsibility on landlords to ensure that rent increases are properly handled and well-supported.
How Much Is a ‘Reasonable’ Rent Increase in 2026?
Whilst there is no fixed cap, a rent increase must align with local market rent.
Tribunals will look at:
-
Comparable properties in the area
-
Property size, condition, and furnishing
-
Transport links and local demand
-
Recent rental listings and achieved rents
Recent data show that average rents across England are around £1,420 per month, whilst those in London average closer to £2,700, with higher figures in commuter areas, and strong demand is expected to continue into 2026.
What Happens If a Tenant Challenges a Rent Increase?
Tenants have the right to challenge a rent increase if they believe it is above market value.
If challenged:
-
The increase is paused
-
A tribunal reviews local market evidence
-
The rent may be reduced, upheld, or set at a different level
-
The decision becomes binding for both parties
This process can delay income changes and create unnecessary administration if the increase is poorly handled.
Can Rent Be Increased During a Fixed-Term Tenancy?
In most cases, rent cannot be increased during a fixed-term tenancy unless the tenant agrees or a valid clause applies (which is now limited after 2026).
Typically, rent is reviewed:
-
At the end of a fixed term
-
When the tenancy becomes periodic
-
Using the correct legal notice
Trying to increase rent mid-term without consent is one of the most common mistakes landlords make.
What Makes a Rent Increase Invalid?
A rent increase may be invalid if:
-
The wrong notice is used
-
The notice is served incorrectly
-
The increase is too frequent
-
The landlord is not legally compliant
-
The proposed rent is clearly above market level
Invalid notices waste time and can weaken a landlord’s position if the tenant disputes the increase.
Key Checks Before Raising Rent in 2026
Before increasing rent, landlords should check:
-
What type of tenancy is in place
-
When rent was last increased
-
Whether the property meets compliance requirements
-
Local market rental evidence
-
Whether communication with the tenant has been clear
