Tenant guidance on rent increases for assured periodic tenancies

Rent levels can change over time, and landlords may review rents to reflect changes in the local rental market, inflation, costs and property improvements.

Not all rent increases are unreasonable and some increases may reflect changes in the local rental market. 

Under the Renters' Rights Act 2025, landlords must follow a legal process when increasing rent for private assured tenancies.

What your landlord must do to increase your rent

If your landlord wants to increase your rent, they must:

• use a section 13 rent increase notice (form 4A)
• give you at least 2 months' notice
• only increase your rent once in a 12-month period
• make sure the notice contains the correct information and proposed start date

 If the correct process is not followed, the notice may not be valid.

If you disagree with a rent increase

You do not necessarily have to accept a rent increase. Speak to your landlord first, as you may be able to agree a different rent without applying to a tribunal.

You may want to discuss whether:

• the proposed rent is in line with similar properties in the area
• you have concerns about affordability
• the property needs repairs or improvements

If your main concern is affordability, budgeting and benefits advice may be available.

How to challenge a rent increase

If you cannot reach agreement with your landlord, you can apply to the First-tier Tribunal (Property Chamber) to determine the open market rent.

You must submit your application before the proposed new rent start date shown on the section 13 notice.

The tribunal is independent and will consider information from both you and your landlord before making a decision.

Tribunal application fee

The application fee is currently £47. You may be able to get help with fees if you receive benefits or are on a low income.

Evidence you will need

The tribunal may ask for:

• a copy of the section 13 notice
• your tenancy agreement
• photographs of the property
• information about repairs or the property condition
• information about similar rents in your area

After you apply

The tribunal will review the evidence submitted by both parties and determine the open market rent for the property. It may determine a lower rent than the amount proposed by the landlord.

If the tribunal decides the notice is not valid, the rent increase cannot take effect.
