How Long Before a Landlord Can Increase Rent in England?

How long before a landlord can increase rent?

For most private rented homes in England, a landlord can generally increase the rent once

in any 12-month period for an assured periodic tenancy. The landlord cannot normally

increase the rent during the first year of the tenancy and must give the tenant at least two

months’ notice using the prescribed Form 4A under the Section 13 process.

That is the short answer. The practical answer is more important: a rent increase is not

simply a commercial decision or an informal message. It is a regulated process involving

timing, tenancy status, notice, market evidence, record-keeping and tenant communication.

Since 1 May 2026, the Renters’ Rights Act 2025 has changed the operating framework for most private rented tenancies in England. Assured shorthold tenancies have generally been

replaced by assured periodic tenancies, and Section 21 ‘no-fault’ possession notices

have ended for the relevant private rented sector tenancies. Rent review clauses that

attempt to provide a different route cannot simply be relied upon under the new

framework.

For landlords and portfolio owners, the strategic lesson is clear: rent reviews should be

planned as a controlled annual process, not treated as an occasional administrative

task.

The 12-month rent increase rule

Under current GOV.UK guidance, rent for an assured periodic tenancy in England can only

be increased once a year. The relevant date is normally the date the previous increase took

effect, not the date when the landlord first considered the increase, sent an informal email

or prepared a notice.

For example, if a lawful rent increase took effect on 1 September 2026, the next increase

would not normally be able to take effect before 1 September 2027. The landlord must also

allow enough time for the tenant to receive the prescribed notice at least two months

before the proposed effective date.

Previous increase took effect Earliest usual next effective Key operational check

date

1 January 2026 1 January 2027 Confirm the previous increase was legally effective

15 April 2026 15 April 2027 Check the tenancy’s rent

period and notice deadline

1 September 2026 1 September 2027 Serve Form 4A in sufficient

time for receipt

The 12-month rule is a frequency rule, not a percentage rule. It does not give a landlord an

automatic right to increase rent by a particular amount. A proposed rent should still be

considered against the open-market rent for comparable properties, the condition and

specification of the home, local demand and the landlord’s wider management strategy.

A well-managed annual review therefore has two separate tests. First, is the increase legally

capable of taking effect on the proposed date? Secondly, is the proposed figure

commercially and evidentially defensible? Passing one test does not automatically pass the

other.

Can a landlord increase rent during the first year?

Current GOV.UK guidance states that a landlord cannot increase the rent during the first

year of an assured periodic tenancy. 1 This means a landlord should not plan an early

increase simply because market rents have moved upwards shortly after the tenancy began.

The position may require closer review where the tenancy began before 1 May 2026, where

a fixed-term arrangement transitioned into an assured periodic tenancy, or where a rent

increase was notified before the new framework came into force. Transitional rules can

affect the outcome, so the tenancy chronology should be checked rather than assumed.

For landlords, the safest operational approach is to record the following dates for every

property:

• the original tenancy start date;

• the date the tenancy became subject to the current assured periodic framework, where

relevant;

• the date of the last rent increase taking effect;

• the earliest next permitted effective date; and

• the date by which the next notice must be received.

For tenants, an increase demanded during the first year should not automatically be

treated as valid. Ask the landlord or agent to confirm the legal basis in writing and seek

independent housing advice before withholding rent or taking any other step.

How much notice must a landlord give?

For a relevant Section 13 increase in England, the landlord must give the tenant at least two

months’ notice before the new rent starts. The notice must be made using Form 4A, the

prescribed form for proposing a new rent for an assured tenancy in the private rented

sector.

The notice should be served in a way permitted by the tenancy arrangements. GOV.UK

guidance identifies personal service, post and email where email service is allowed by the

tenancy agreement. Landlords should retain evidence of what was served, when it was

served and how it was delivered.

A landlord who wants a new rent to start on 1 October should plan backwards from that

date. The tenant must receive a valid Form 4A at least two months beforehand, and the

proposed start date must be checked against the tenancy’s rental period and the

statutory requirements. Posting a notice close to the deadline creates avoidable risk

because the relevant issue is receipt, not simply the date the document was placed in the

post.

An informal conversation, text message or email can be useful for opening a discussion, but

it is not a substitute for the prescribed process where Section 13 applies. GOV.UK guidance

states that the Section 13 process must be followed every time the rent is increased, even

where the landlord and tenant have already discussed or agreed the increase.

What is Form 4A and why does it matter?

Form 4A is the prescribed landlord’s notice proposing a new rent for assured tenancies in

the private rented sector. The form is designed to provide the tenant with clear information

about the proposed rent and the process available if they disagree.

Landlords should use the current official version and avoid changing its wording unless the

form expressly permits an adjustment. GOV.UK warns that altering prescribed forms can

affect their validity.

Before serving Form 4A, a landlord or managing agent should check the following:

Compliance point Evidence to retain

Tenancy type and applicable rules Current tenancy record and legal review notes

Last rent increase date Previous notice, agreement or rent schedule

Proposed rent Comparable market evidence and valuation

rationale

Effective date Calculation showing the 12-month and two month

rules are met

Prescribed notice Completed Form 4A copy

Service Proof of delivery or permitted email record

Follow-up Tenant correspondence and any agreed outcome

This level of documentation is not unnecessary bureaucracy. It gives a portfolio owner an

audit trail, helps prevent inconsistent instructions and makes it easier to respond to a

tenant query or challenge.

Is there a maximum percentage rent increase?

There is no universal percentage cap for private rents in England under the general assured

periodic tenancy rent-increase process. However, that does not mean a landlord can impose any figure without scrutiny.

If a tenant believes the proposed rent is higher than the open-market rent, they may be able to apply to the First-tier Tribunal for a market rent determination. The tribunal considers what rent the property could reasonably achieve on the open market and cannot set the rent above the amount proposed by the landlord.

A defensible rent review should compare genuinely similar properties rather than relying on a headline average. Relevant factors may include location, floor area, bedroom and bathroom configuration, condition, furnishing, parking, outdoor space, energy performance, accessibility, amenities and the quality of property management.

Market evidence is only one part of the decision. A landlord should also consider the cost of

voids, re-letting, compliance work, repairs and tenant turnover. A reliable tenant who pays

on time and looks after the property has operational value. Pursuing the highest theoretical

rent may not produce the strongest net outcome if it triggers a void period or additional

remedial expenditure.

This is where a structured rent review becomes a portfolio strategy rather than a simple

price adjustment. The right question is not only, “What could this property achieve?” It is

also, “What rent is supportable, sustainable and appropriate for this asset and this

tenancy?”

What if the landlord serves notice too early?

A notice served too early or with the wrong effective date may be defective. It does not

necessarily mean rent can never increase, but the landlord may need to serve a corrected

notice and use a later effective date.

The tenant should check the date of the last increase, the proposed new rent date, the date

the notice was received and whether Form 4A was used. Both parties should keep copies of

the notice and related correspondence.

Tenants should not stop paying rent without independent advice. Doing so can create

arrears and may lead to separate legal consequences. A tenant who believes the proposed

rent is above market should obtain advice promptly about the First-tier Tribunal process

and any applicable deadline. Shelter states that a tenant cannot be evicted simply for

challenging a rent increase under the relevant protections.

Landlords should treat a challenge as a prompt to review their evidence and process, not as

a reason to escalate communications. Clear comparables, accurate dates and a professional

tone can reduce the likelihood of an avoidable dispute.

Transitional issues after 1 May 2026

The current rules include important transitional points. GOV.UK guidance states that where

a landlord used Form 4 before 1 May 2026, the notice period and increase stated in that

form can continue to apply even if the new rent starts after 1 May 2026. It also states that

the next increase cannot take effect until at least a year after the last increase took effect,

including where that earlier increase took effect before 1 May 2026.

The treatment of a rent review clause also requires care. An increase agreed before 1 May

2026 but due to take effect after that date may not apply where the new rules prevent it.

A change of paperwork should not be assumed to reset the clock. Whether an arrangement

is genuinely a new tenancy, a continuation of occupation or a transition from a previous

tenancy structure can affect the analysis. Landlords should not attempt to bypass the

annual rule by asking a tenant to sign a new agreement at a higher rent without checking

the applicable law.

Where the chronology is complex, independent legal advice is more reliable than a generic

template or an informal online explanation.

A practical rent review process for landlords

A compliant and commercially sensible process begins well before the notice deadline. At least several weeks before the earliest permitted review date, the landlord or agent should audit the tenancy record, assess the local market, inspect the property information and identify any outstanding repairs or compliance actions.

The proposed figure should then be tested against comparable evidence and the landlord’s objectives. If the property is below market because of unresolved repairs or outdated presentation, investment in the asset may be more appropriate than relying solely on a rent increase. If the rent is already broadly aligned with comparable homes, a modest and clearly explained review may support retention and reduce dispute risk.

The final stage is controlled service and follow-up. Use the correct form, calculate the dates

carefully, serve it through an authorised method and retain proof. Update the rent schedule

only once the increase is legally effective. A central register should show each property’s

current rent, last increase date, earliest next review, notice deadline, proposed figure,

evidence and completion status.

For landlords with multiple properties, this process can be managed through a rent-review

calendar integrated with compliance and property-management records. That creates visibility across the portfolio and reduces reliance on memory, spreadsheets held by

individuals or inconsistent local practices.

Frequently asked questions

Can a landlord increase rent every 12 months?

Generally, yes, for an assured periodic tenancy in England, but only once in a 12-month

period. The landlord must also avoid the first-year restriction, use Form 4A and give at least

two months’ notice.

Can rent increase after six months?

Usually not for an assured periodic tenancy if the proposed increase would take effect

within 12 months of the previous increase or during the first year of the tenancy.

Transitional circumstances and tenancy status should be checked.

Does a landlord need the tenant’s agreement?

The landlord must follow the Section 13 process even if the tenant has discussed or agreed

the proposed increase. Agreement alone does not replace the prescribed notice where

Section 13 applies.

Is there a maximum rent increase percentage?

There is no general fixed percentage cap for private rents in England. The proposed rent

may be challenged if it is above the open-market rent, and the landlord should retain

credible comparable evidence.

Can a tenant challenge a rent increase?

A tenant may be able to apply to the First-tier Tribunal for a market rent determination if

they believe the proposed figure is above open-market rent. They should obtain

independent advice about the application process and deadlines.

Do these rules apply across the UK?

No. Housing law is devolved. This article focuses on private rented housing in England.

Scotland, Wales and Northern Ireland have different legal frameworks and procedures.

Can a landlord use a rent review clause instead?

For the relevant assured periodic tenancies under the post-1 May 2026 framework, a rent

review clause cannot simply be used as an alternative route to the statutory process. Check

the current guidance and obtain independent legal advice where the tenancy history is

complex.

A better approach to rent reviews

Rent increases are most effective when they form part of a wider operating plan. Accurate
