The average number of new prospective tenants registered per estate agency branch increased to 107 in August, up from July’s figure of 102, according to the latest figures from ARLA Propertymark.

This is the highest figure ever recorded, breaking last month’s previous record.

The data also shows that the number of tenants experiencing rent increases jumped significantly for the second month in a row in August, as 79% of agents saw landlords increasing rents compared to 71% a month earlier.

This is the highest rate increase on record, beating the previous record of 68% in May this year for a second month running.

Regionally, Scotland had the highest number of properties managed per letting agent branch with a figure of 251. However, rental stock was the lowest in London with an average of just 126  properties managed per branch.

Propertymark’s CEO Nathan Emerson commented: “The continued increase in demand from tenants, coupled with the decreasing amount of rental stock available  means we are seeing a worrying increase in rent prices for the second month running. The private rented sector provides homes for approximately five million UK households and it is vital the service being provided by landlords is recognised. With the increasing pressure, more landlords need to be incentivised into the sector.

“We look forward to meeting the newly appointed Secretary of State and his team over the coming months to ensure keeping the rent flowing is high on the Department’s agenda going forward, and we have a close eye on the overall sector for the rest of the year as the growing concerns over house buyers jumping ship from the buying and selling market is bound to put extra pressure on the private rental sector.”
