The Mayor of London Boris Johnson announced plans in December last year to deliver 55,000 affordable homes in the capital by 2015.
Of the 425 homes started in the first half of 2012, only 171 were started under the Government's Affordable Homes Programme (AHP), under which £1.8 billion have been allocated to be redistributed to housing providers to develop more homes. The scheme includes an affordable rent mechanism that allows housing associations to charge new tenants up to 80 per cent of market rents.
