Almost three-quarters of landlords failed to secure their proposed rent increase in full in tribunal cases decided in September, according to analysis from Cyborg Finance.

The mortgage adviser reviewed 74 First-tier Tribunal decisions in England and found that 71.6% resulted in a smaller increase than requested, no change, a rent reduction or the case being struck out.

Just 28.4% of landlords received the full increase they sought.

However, more than two-thirds of cases still resulted in some form of rent rise.

A higher rent was awarded in 67.6% of cases, either in full or in part.

Average monthly rent rose from £1,372 to £1,464, an increase of £92 a month or £1,104 a year.

Cyborg says the aggregate increase of 6.7% was slightly higher than the 6.3% recorded in August.

Its wider tracker shows an average of around 91 days between a landlord serving a rent notice and a tribunal decision in cases recorded since May.

Cyborg Finance mortgage adviser Mark Hosker says: “The rent a landlord proposes and the rent a tribunal determines are not always the same.

“Landlords should be ready to support proposed rents with comparable local evidence, while tenants should remember that challenging an increase does not guarantee their rent will stay unchanged.

“More than two-thirds of September cases still resulted in an increase, with rents rising 6.7% overall.

“However, with a challenge potentially delaying higher rent payments by around four months, and nearly three-quarters of landlords failing to secure their full proposed increase, the £47 tribunal fee could prove money well spent.”

Cyborg says the figures cover published tribunal decisions and may not capture every case decided during the month.
