The latest figures showed that 9,205 affordable homes were built in 2018/19, just over half of the 18,120 constructed at the capital’s peak in 2014/15.

The London Assembly estimates that 43,000 new affordable homes are needed each year up to 2041 to meet demand.

Andrew Southern, chairman at Southern Grove, commented: “Years of abysmal housebuilding rates have left London with an enormous black hole in its provision of affordable homes.”
