Almost a quarter of private rented homes fail to meet minimum standards, according to Ajay Jagota, head of north east lettings and sales firm KIS.

Having analysed the latest English Housing Survey, released last week, the letting agent, who also heads up property insurance firm Veriwise, says that 23% of privately rented homes, and 12% of socially rented properties, are offered by landlords in substandard condition.

Jagota says that the research also shows that 17% of private tenants are not satisfied with the standard of their homes, while a quarter of renters report that they are dissatisfied with the repairs and maintenance carried out by their landlord, with a landlord refusing to carry out repairs their biggest complaint.

The figures provided by the letting agent also claim that an estimated 820,000 homes in England have a problem with damp, 13% of privately rented homes contain a hazard such as damp or mould, faulty heating systems, unhygienic food storage – such as a lack of a working fridge or dangerous electrics.

Furthermore, 11% of privately rented homes do not have a working smoke alarm.

The three most common reasons for private renters being dissatisfied with repairs and maintenance were:

+ Landlord not bothering with repairs or maintenance (35%)

+ Landlord being slow to get things done (25%)

+ Landlord doing the bare minimum (15%).

Jagota said: “These are outrageous figures which really bring home how many people in England are living day in day out in danger and squalor as a result of their landlords not taking their responsibilities seriously.

“In every corner of the country there are renters wondering why their landlord won’t get rid of rats or wondering how long a landlord has to fix an electrical problem or can legally leave them without heating – all knowing that any complaints will probably get them nowhere.

“Countless council house and privately rented tenants are being told year after year that the damp in their children’s bedroom is their fault for not opening the windows or drying clothes in the house – and most of them don’t know where to turn to or don’t have the confidence or resources to fight their case in court.
