One in five private tenants in Britain describes their current renting conditions as a ‘nightmare’.

A survey of 2,000 tenants by boiler company Help-Link found that 19% live in a home with damp; one in ten will be living in a house without heating this winter; and 16% of tenants live in homes with mould.

Other issues include building faults (11%), water leaks (14%), damaged windows (9%), pests (1 in 20) and broken fire alarms (4%).

One in three of tenants who said they lived in poor conditions also complained that they did not receive their full deposit back, with the average tenant losing around £355.

According to the Deposit Protection Service, around 50% of deposits are returned to tenants in full.
