London Councils has responded to new figures from Shelter highlighting that the capital has the highest homelessness rates in England.
Cllr Darren Rodwell, London Councils' Executive Member for Housing & Planning, said:
"These appalling figures show the massive scale of homelessness - with London facing the worst crisis in the country.
"London boroughs are committed to tackling this priority issue, but for too long we've been without the powers and resources needed to stop the rising tide of homelessness and build adequate numbers of affordable homes.
"London boroughs look forward to working positively with the new government to redouble our efforts to prevent homelessness and deliver the affordable housing that London desperately needs."
With MHCLG funding, London boroughs are working collaboratively through Capital Letters to improve the procurement and management of properties in London for alleviating and preventing homelessness.
Recent research shows that homelessness costs boroughs £200 million every year and is set to grow to unsustainable levels if trends continue.
To boost council housebuilding, London Councils is calling on the government to end all restrictions on local authorities' use of Right to Buy receipts (so that all money generated from council house sales can be reinvested in local replacements) and to set out long-term social rent levels.
London Councils is also calling on the government to raise Local Housing Allowance rates to cover at least 30% of local market rents. London Councils research shows that the LHA freeze has been a major contribution to homelessness in the capital.
