How to challenge a rent increase in the tribunal
Guide for professionals
Apply to the tribunal
A tenant can challenge a rent increase through the tribunal if their landlord has proposed an increase above market rent.
Check the application deadline
Check the section 13 notice for the date the new rent starts. An application must be submitted to the tribunal before this date.
A challenge cannot be made out of time if the deadline is missed.
Calculate the market rent
The tribunal sets the new rent by assessing the market rent for the property. It uses average rents for similar private properties in the local area.
Research market rents
A tenant can gather evidence of listings from websites like Rightmove, Zoopla and SpareRoom. Look for similar properties in the area and consider:
the location
the size of the property
the condition of the property
whether it is furnished or unfurnished
Online rent calculators can give a rough estimate of market rent, but they don't always reflect the true market value for a specific property.
You can look at previous tribunal decisions to see what rents have been set for similar properties in the area. Check previous tribunal decisions on GOV.UK.
The tenant can also ask family, friends and neighbours how much rent they pay for similar properties.
Factors to take into consideration
Consider any factors that might devalue the property, such as poor housing conditions, if there is no lift in a block of flats or no parking.
Ignore any home improvements that the tenant has paid for when comparing rents.
Advise the tenant to take screenshots, record the dates of any listings and keep records of all research. This will be useful when collating evidence for the tribunal.
Decide the merits of the case
Consider whether there is merit in challenging the rent increase based on:
validity of the notice
personal circumstances of the tenant
likelihood that the tribunal will set a lower rent than the landlord
The tribunal's role is to set the market rent for the property. This can be higher than what has been proposed by the landlord.
If the tribunal agrees to the rent increase, it will be backdated to the date on the section 13 notice. Advise your client to save the extra rent if they can, to prevent rent arrears.
