Rent & Notice Details
Use the actual tenancy period, which may differ from the payment collection date. Monthly dates on the 29th–31st are modelled as the last day in shorter months; check your agreement if this is unclear.
Required if the rent has increased before.
Required for a previous increase: Form 4A uses this to check the 52/53-week rule. If your history is unknown or predates this rule, get advice.

Which Rules Does This Tool Use?
For England private assured periodic tenancies, notices served from 1 May 2026 use Section 13 and Form 4A. Most existing assured shorthold tenancies became assured periodic tenancies on that date. A former fixed term or rent review clause does not provide a separate route to raise the rent under this system.
How Is The Date Calculated?
The model takes the later of two calendar months after service and the annual increase limit, then moves forward to the beginning of a tenancy period. Form 4A requires 52 weeks before a first increase and normally 52 weeks after the previous increase. A 53rd week is required when the 52-week date would fall more than six days before the anniversary of the first increase after 11 February 2003.
What Must I Check Before Serving?
Confirm the tenancy type, actual service date, tenancy period and full increase history. Missing history, transitional notices, altered tenancy periods and disputes need individual advice. For monthly dates on the 29th–31st, the model uses the last day of shorter months; confirm that convention matches the tenancy.
What Does The Tenant Receive?
Use the official Form 4A without changing its prescribed wording. Complete every applicable section, including charges within the rent, signatures and the tenant guidance. The notes generated here are for preparation only and cannot be sent as a substitute notice.
Can The Tenant Challenge The Increase?
A tenant can refer the proposed rent to the First-tier Tribunal before its proposed start date. The tribunal considers market rent and other relevant circumstances. Read the current official tenant guidance and seek advice promptly if there is a dispute.
What Happens Next?
Check local comparable rents, discuss affordability and retain service records. A timing result does not assess market rent or establish that a notice is legally valid. Model the wider costs with the Buy To Let Cash Flow Sensitivity Calculator.
Frequently Asked Questions
Is this an official rent increase notice?
No. It produces preparation notes only. For an England private assured periodic tenancy, complete and serve the official Form 4A.
How much notice is required?
At least two calendar months for notices served from 1 May 2026 within this tool’s England scope. Annual limits and the start of a tenancy period may require a later date.
Can I use a fixed-term rent review clause instead?
For private assured tenancies covered by the England reforms from 1 May 2026, use the Section 13 process. An old fixed term or rent review clause is not an alternative increase route.
Can rent rise during the first year?
The first increase cannot start until 52 weeks after the tenancy began. It must also meet the notice and tenancy-period requirements.
Why do you ask for two previous increase dates?
The most recent increase sets the usual 52-week interval. The first increase after 11 February 2003 anchors the annual cycle and determines whether 53 weeks are needed under Form 4A Note A3.
What if I do not know the rent history?
The tool will not mark timing checks as passed. Establish the dates from records or obtain advice before proposing an increase.
Does the rent collection date determine the start date?
Not necessarily. Use the beginning of an actual tenancy period, which may differ from a standing-order collection date.
Can I use this elsewhere in the UK?
No. Wales, Scotland and Northern Ireland have different rules. This tool also excludes social housing, agricultural occupancies and other tenancy types.
Does it handle notices served before 1 May 2026?
No. Transitional rules may apply to older notices. Consult the official guidance or an adviser.
Can a tenant challenge the proposed rent?
Yes. A tribunal referral must be received before the proposed increase starts. Check the current official guidance for the process and deadlines.
Does a passed timing check mean the notice is valid?
No. It checks the entered dates within stated assumptions. Tenancy status, service, form completion, market rent and other legal requirements still need checking.
How is the increase percentage calculated?
Subtract current rent from proposed rent, divide by current rent and multiply by 100. Both figures must cover the same rental period.
