Bradford Council received the biggest rise in complaints against private landlords in the county in the last decade, it has been revealed.

Research by residential letting specialists Linley & Simpson, which has a base in Ilkley, shows the number of complaints investigated rocketed from 263 in 2000 to more than 1,313, in 2010.

A total of 1,130 of the complaints were against individual property owners and 183 against letting agents.

A Freedom of Information request by the letting specialists has revealed prosecutions and legal notices across Yorkshire are also at an all-time high, with some landlords being left out of pocket to the tune of more than £20,000 after being convicted of serious breaches of the law which were judged to put their tenants’ lives at risk.

The research comes as experts predict a record one-in-six UK homes will be supplied through the private rented sector by the end of this year.
