How Much Can Landlords Increase Rent in England?

The Short Answer: There is no automatic percentage—but there is a process

Landlords often ask whether a 3%, 5% or 10% rent increase is permitted. For most private rented homes in England, the answer is not a simple percentage. Since 1 May 2026, the Renters' Rights Act framework has required private landlords to use a clearer, more consistent route: for an assured periodic tenancy, rent can ordinarily be increased once in each year, not during the tenancy's first year, and only through the statutory Section 13 process using Form 4A with at least two months' notice.

There is no general statutory percentage ceiling for these rent increases. That does not mean a landlord has free rein to select a figure without evidence. If a tenant considers the proposed rent above the property’s open-market rent, they can apply to the First-tier Tribunal (Property Chamber ) for a determination. The tribunal can assess the market rent using the information provided by both parties.

The commercially sound question is not “What percentage can I add?” It is “What rent can I evidence, communicate and sustain?”

That distinction matters. A rent review should strengthen a portfolio’s long-term performance rather than create avoidable disputes, arrears or a costly void. For professional landlords, rent is not simply a monthly number. It is the result of positioning, property standard, tenant demand, operational discipline and compliance.

This guide focuses on private rented assured periodic tenancies in England. Different systems apply in Wales, Scotland and Northern Ireland. Social housing assured tenancies also follow different rules, while a short-stay or serviced-accommodation booking arrangement may be governed by contract and consumer law rather than this private tenancy process.

Rent increase rules in England from May 2026

The Renters’ Rights Act 2025 changed the private rented sector in England from 1 May 2026. Most existing assured shorthold tenancies became assured periodic tenancies, new private tenancies are periodic, and Section 21 is no longer available for private rented properties.

For rent reviews, the operational message is direct: do not rely on an old rent-review clause as a substitute for the current statutory route. Government guidance states that landlords must use the Section 13 process every time they increase rent, including where an increase has already been agreed.

notice’s validity.

Transitional rent increases: check the date before acting

A landlord must not assume that every previous arrangement disappears. A Form 4 notice served before 1 May 2026 can remain effective even if the increase was due after that date. However, Government guidance says a new increase cannot take effect until at least a year after the last increase took effect, whether the earlier increase arose through a Form 4 notice or a rent-review clause. An increase agreed under a rent-review clause before 1 May 2026 but due to take effect afterwards does not apply.

The practical lesson is clear: check the tenancy, previous notices, effective dates and service evidence before setting the next review date. This is especially important across larger portfolios where property records have been inherited, migrated between systems or managed by different agents over time.

How much can a landlord increase rent? Let market evidence lead

A percentage is a calculation. Market rent is the decision. An increase may be modest in one postcode and more substantial in another. It may be appropriate to make no increase at all where the existing rent is already competitive, the property needs attention or local demand is softening.

For an assured periodic tenancy, the relevant test in a tenant challenge is the property’s open-market rent: broadly, what the landlord could expect to receive if the property were re-let on the open market. It is not automatically the highest figure displayed on a portal, a neighbour’s anecdote or the landlord’s cost base.

Government tribunal guidance specifically recognises evidence from similar nearby properties by size, features and location. It notes that actual rental agreements are generally stronger evidence than portal or letting-agent information, although portal and agent evidence can still be useful.

Build a defensible rent-review evidence pack

A credible review begins before a notice is drafted. The aim is not to overwhelm the tenant with paperwork; it is to ensure the proposed figure is based on a professional, repeatable assessment.

The strongest evidence is specific, dated and balanced. A two-bedroom flat with a new kitchen, parking and strong transport access is not directly comparable with a tired two bedroom flat a mile away with no parking. Equally, three aspirational listings are not proof that tenants will pay the amount requested. A property that remains advertised for an extended period may signal that the market is resisting the asking rent.

Mortgage costs do not set the open-market rent

Higher mortgage rates, insurance premiums, repairs, licensing costs and compliance expenditure are real business pressures. They are legitimate reasons to assess a portfolio’s pricing and operating model. They do not, by themselves, establish the openmarket rent in a Section 13 process.

This is where professional management creates a genuine advantage. Rather than forcing every cost increase onto a single tenancy, a stronger strategy considers asset quality, rent position, operating margin, void risk, retention and planned works together. That is the difference between reacting to pressure and managing income deliberately.

Rent reviews that protect income as well as compliance

The highest possible rent is not always the best commercial outcome. A £75 monthly increase has an annual headline value of £900. But if the approach triggers a vacancy, reletting costs, cleaning, repairs and a period without income, the net benefit can disappear quickly. No rent review should be considered in isolation from the cost of turnover and the value of a reliable tenant.

A sensible rent-review programme starts with a single portfolio register. It should identify the tenancy type, rent-payment date, current rent, last effective increase date, earliest lawful next date, notice-service deadline, comparable evidence and planned communication. A review undertaken in the final week, with little data and no clear audit trail, is an avoidable risk.

The correct Section 13 rent-increase process

First, confirm that the tenancy is within the private assured periodic framework and that this is not a social-housing tenancy, licence, lodger arrangement or a tenancy in a different UK nation. Second, check that the proposed effective date meets the annual timing restriction and that the intended notice period is at least two months.

Third, agree the commercial case internally: current rent, proposed rent, local evidence and tenant-retention position. Fourth, complete the prescribed Form 4A accurately. The form should not be casually rewritten or replaced with an informal letter, as Government guidance stresses the importance of using prescribed forms without altering their wording unless the form allows it.

Finally, serve the notice using a permitted method, retain a complete copy and proof of

service, update the rent ledger and log the tenant’s response. An email, text or conversation can help make the change understandable. It does not replace the formal notice.

What happens if a tenant challenges a rent increase?

A tenant who considers the proposed rent above market rent, or who believes the notice is

legally invalid, can apply to the First-tier Tribunal before the proposed new rent start date.

The tribunal’s current online and paper process is described by HM Courts & Tribunals

Service.

The tribunal can review the evidence from the tenant and landlord, and may make a decision from the papers, hold a hearing or arrange an inspection if necessary. Where it determines the market rent, the result may be lower than, or the same as, the rent proposed in the landlord’s notice.

For landlords, this reinforces the value of being prepared. Keep the evidence pack, the completed Form 4A, tenancy documentation and service records together. A calm, transparent explanation of how the figure was reached can often resolve questions before a formal dispute arises.

It is also worth separating rent review from possession strategy. Since the May 2026 changes, private landlords cannot use the Section 21 process. Possession, where needed, depends on an applicable statutory ground and the proper process. A rent challenge should be handled fairly and professionally; it is not a reason to make assumptions about a tenant’s security of tenure.

Specialist portfolios: HMOs, supported accommodation and short stays

A strong rent-review system must be tailored to the operating model. In a private HMO occupied under assured periodic tenancies, the Section 13 process may apply to each relevant tenancy, but rent evidence should reflect the individual room, shared facilities, bills or services included, licensing status and local tenant demand. Licensing, fire safety and management responsibilities remain separate compliance duties; a rent increase does not cure a property-standard issue.

Social housing and supported accommodation require further care. Social-housing assured tenancies use different forms and are not yet covered by the private rented sector changes in the same way; Government guidance indicates that the relevant changes for social housing will not apply until 2027 at the earliest. 4 Rent-setting may also involve regulatory, contractual, funding and benefit considerations. Seek specialist advice before applying a private-sector rent-review model.

For serviced accommodation, guest stays and corporate short lets, the Section 13 process will not automatically be the right framework. Pricing, planning, safety, consumer obligations, tax treatment and the contract in use should be reviewed separately. Businesses operating across long-stay and short-stay models need a disciplined distinction between the two rather than a one-size-fits-all policy.

A better rent-review conversation supports better outcomes

A formal notice is necessary. Good communication is still valuable. Before or alongside a properly served Form 4A, explain the proposed new rent, the effective date and the fact that the review has been assessed against the local market and the property’s specification. Be ready to listen to evidence from the tenant as well.

Professional communication does not mean avoiding difficult commercial decisions. It means making them transparently, consistently and with the evidence to support them.

This protects the landlord’s position, respects the tenant and enhances the reputation of

a well-managed portfolio.

Frequently asked questions about landlord rent increases

Is there a maximum percentage a landlord can increase rent by in England?

There is no general statutory percentage cap for an assured periodic tenancy in England. The landlord must follow the Section 13 process and the tenant may challenge a proposed increase that they consider above open-market rent. The figure should be supported by property-specific market evidence, not a generic percentage.

Can a landlord increase rent by 10% in one year?

A 10% increase is not automatically unlawful simply because of its percentage. However, the annual timing rule, at least two months’ notice and Form 4A process still apply. If the proposed rent is above open-market rent, the tenant can apply to the First-tier Tribunal before the proposed start date.

Can a landlord increase rent twice in one year?

No, not for an assured periodic tenancy within the post-May 2026 private rented sector

framework in England. Government guidance states that rent can be increased once a year

and not during the first year of the tenancy. Check previous effective dates before planning

the next review.

Does a landlord need to use Form 4A even if the tenant agrees?

Yes. Government guidance states that the Section 13 process and Form 4A must be used

every time a landlord increases rent, including where an increase has already been agreed.

How much notice does a landlord need to give for a rent increase?

For the relevant assured periodic tenancy in England, at least two months’ notice is

required using a completed Form 4A. Notice may be given in person, by post, or by email if

the tenancy agreement permits email service.

What evidence is useful if a rent increase is challenged?

Useful evidence includes the tenancy agreement, notice, service records, property photographs, room sizes, specification, repairs or improvements, local amenities and comparable nearby rental evidence. HMCTS guidance says actual rental agreements are usually stronger evidence than advertised listings, although agent and portal information may still assist.

Do the same rules apply in Wales, Scotland and Northern Ireland?

No. Housing law and rent-increase procedures differ across the UK. This article is about the

private rented sector in England. Landlords and tenants should use the law and official

guidance for the nation in which the property is located.
