The G15 has said housing associations will need £54bn to deliver the number of social homes outlined in the London Plan over the next five years.

Fiona Fletcher-Smith, chair of the G15 and chief executive of L&Q warns the government not to lose sight of affordable and social housing in its housebuilding plans.

The group, which consists of London’s largest housing associations, has drawn on figures from the Greater London Authority and Savills to estimate an affordable home in London costs £450,000 to build.
