Over 3,700 homeless Barnet families have been re-housed in temporary accommodation outside the borough over the last five years according to official Barnet Council figures (2011/12-2015/16).
Barnet Council placed 3,244 families elsewhere in London, and 459 families outside London.
The Conservative-run Council has failed to meet their own affordable housing targets over the last three reported years, with an average of only 28% of all homes completed being 'affordable' between 2012/13-2014/15 (1,096 affordable homes) against a target of 40%.
In the previous three years Barnet Council only delivered 27% affordable homes (679 homes between 2009/10-2011/12).
In 2015/16 only 18% affordable homes were delivered (257 homes).
Lack of affordable housing has been the top concern in successive Residents' Perception Surveys over the last few years.
Labour Group Deputy Leader and Housing spokesperson, Cllr Ross Houston said: "The figures show that the need for affordable homes is outstripping supply - Conservative-run Barnet Council is failing to deliver the number of affordable homes Barnet's families need, or even to meet their own targets.
"The result is that thousands of families accepted as homeless by the Council are having to be placed in temporary accommodation outside of the borough.
"Every time Barnet Council fails to deliver affordable housing they are failing local families who desperately need their help.
"But the Barnet Tories are utterly complacent about this and don't seem to care - when I asked the Housing Committee Chair at last week's Council meeting if he thought these figures were evidence that Barnet's housing market is broken he just said "No"."
