Lambeth Living, which manages social housing for Lambeth council, has 1,090 properties empty, 848 for more than three months, and 18,000 households on its housing waiting list — 8,000 of those families of two or more.
A spokeswoman said empty properties were usually awaiting repair, redecoration or re-letting. Experts also warned the empty houses were a magnet for squatters after figures also revealed that squatters have taken over 343 empty homes in London in the past year.
