Half of parents in London think their children will be priced out of their home town. According to figures from a new YouGov poll for the National Housing Federation, 52% of think it is unlikely their children will be able to afford to buy or rent in the area they have grown up in, the highest rate in England.

Across England, average rents rose by 4.6% from £161 per week in September 2011 to £168 per week in September 2013.

The poll found 72% of English parents are worried about rising rent levels and 81% about rising house prices and the impact of both on the next generation. It also revealed that more than two thirds of parents (69%) overall fear children won't be able to afford a home in future without their financial support.

Katie Teasdale, external affairs manager at the National Housing Federation, said: "Parents should look forward to a bright and prosperous future for their children but are worried that they will end up being worse off than them.

"Are we really ok with the idea of some of our towns and cities being priced beyond the pay packets of young people. How will our communities survive if young people can't afford to live there? This is the situation we're facing if we don't tackle the housing crisis.

"It's taken a generation to create this broken housing market and will take us a generation to get out of it. We're calling on the political parties to commit to to end the housing crisis within a generation to ensure the situation doesn't continue to worsen leaving our children to deal with the consequences. We want the next government to publish a long-term plan within a year of taking office that sets out how they will achieve this."
