England Rent Increase Rules 2026: Form 4A, Advance Rent and Rental Bidding
The Renters’ Rights Act 2025 changed several rules about rent in England’s private rented sector on 1 May 2026. Landlords now need to distinguish between increasing the rent for an existing tenant, requesting payment before a new tenancy starts, and setting the advertised rent for a property.
Each has its own requirements. Following the correct procedure matters even when the landlord and tenant have discussed a figure and appear to agree.
How can a landlord increase rent in 2026?
For an assured periodic tenancy in England, a landlord must use the revised section 13 procedure to increase the rent. This means completing and serving Form 4A: Landlord’s notice proposing a new rent, giving the tenant at least two months’ notice before the proposed increase takes effect.
The government’s rent increase guidance for landlords says this process must be followed every time the rent increases, even if the tenant has already agreed to the proposed amount. A conversation or email agreeing a new figure does not replace the prescribed notice. GOV.UK
Landlords can obtain the current Form 4A from GOV.UK. Check the form carefully, including the tenant and property details, proposed rent and date on which it is intended to start. Keep a copy of the completed notice and evidence of how and when it was served. Government guidance lists personal delivery, post and email where the tenancy agreement permits email service. GOV.UK
How often can the rent increase?
The rent can generally be increased only once a year, and the government’s guidance says it cannot be increased during the first year of the tenancy. Before preparing Form 4A, check both the tenancy start date and the date the last increase took effect. The relevant anniversary is the date the previous increase took effect, rather than simply the date a landlord last discussed rent with the tenant. GOV.UK
For example, if a rent increase took effect on 1 February 2026, the government’s example says the next increase cannot take effect before 1 February 2027. This remains relevant where the earlier increase happened before the new rules began. GOV.UK
What if the tenant thinks the new rent is too high?
A tenant who believes the proposed rent exceeds the open-market rent can ask the First-tier Tribunal to decide the rent. Open-market rent broadly means what the property could be expected to achieve if it were newly offered to let.
Before serving notice, landlords should therefore look at genuinely comparable local properties. Consider location, size, condition, facilities and whether the advertised properties are reasonably comparable to the home being let. Retain the evidence used to reach the proposed figure. The tribunal process is explained in the government’s rent increase guidance. GOV.UK
What about rent increase notices served before 1 May 2026?
The date and method of an earlier increase can matter. Government guidance says that where a landlord served Form 4 before 1 May 2026, the notice and increase stated in it can still apply, even if the new rent began after 1 May. It also explains that an increase agreed under a rent review clause before 1 May but due to take effect after 1 May will not apply. Landlords dealing with a change arranged around the commencement date should check the specific transitional guidance before demanding the higher rent.
How much rent can be requested before a tenancy starts?
A landlord or letting agent must not ask for, encourage or accept rent before both landlord and tenant have signed the tenancy agreement. After signing, and before the tenancy starts, the landlord can generally request up to one month’s rent where rent is payable monthly, or 28 days’ rent where it is payable on another basis.
The government calls this interval after signing and before the start date the pre-tenancy period. Its rent in advance and deposits guide describes limited circumstances in which more may be requested, including certain council-arranged homelessness accommodation and social or supported housing. Landlords should check that an exception actually applies before relying on it. GOV.UK
Rent in advance is different from a deposit. The government guidance separately addresses holding deposits and tenancy deposits, including their limits and the requirement to protect a tenancy deposit in an approved scheme. Labelling an extra rent payment a “deposit” does not remove the need to follow the rules governing what the money actually is.
Once a tenancy has started, a tenant may choose to pay rent early, but the landlord cannot require them to do so merely to get around the pre-tenancy limit. gov.uk
Are rental bidding wars allowed?
No. A landlord or agent advertising a property must publish an asking rent and must not ask for, encourage or accept an offer above that advertised amount. This applies even if an applicant volunteers a higher figure. Asking applicants for their “best and final offer” above the published rent is therefore inappropriate under the new rules. www.gov.uk
Before placing an advert, decide the asking rent using suitable market evidence. Make sure the figure is consistent across property portals and instructions to agents. If several suitable applicants express interest, select an applicant through a fair assessment process without turning the selection into a bidding exercise.
A practical check before acting
For an existing tenancy, establish when the tenancy and last rent increase began, assess the proposed market rent and serve the current Form 4A with the required notice. For a new tenancy, check that both parties have signed before requesting rent, observe the usual pre-tenancy limit and ensure the advert states the asking rent clearly.
These checks help avoid disputes and give both landlord and tenant a clear record of how the rent was set.
