The research is released ahead of an expected speech on national planning reforms by Sajid Javid, the secretary of state for housing, communities and local government.
Looking at eight rural councils over one year, the analysis shows that half the affordable homes that councils were required to build were lost when viability assessments were used – demonstrating that the housing crisis is not just confined to our cities, but is having a serious impact in the countryside as well.
Developers use ‘viability assessments’ to argue that building affordable homes could reduce their profits to below around 20%, which gives them the right to cut their affordable housing quota.
It means developers are over-paying for land and recouping the costs by squeezing the affordable housing commitments – a tactic often used by developers building big housing schemes.
This comes months after Shelter carried out similar research on housing lost to viability assessments in urban areas. Together, the research paints a national picture of the affordable housing drought right across the country.
Shelter and CPRE are calling on the government to use their current review of planning rules to stop developers from using this loophole to wriggle out of providing the affordable homes that communities desperately need.
Polly Neate, Shelter chief executive, said: “With this new research, we can see for the first time the true scale of our housing crisis – it’s not just blighting cities but our towns and villages too.
“Developers are using this legal loophole to overpower local communities and are refusing to build the affordable homes they need.
“The government should use their current review of planning laws to close this loophole and give local communities the homes they really need. This process must act as a critical turning point in the government’s attitude towards affordable housing in this country.”
Crispin Truman, Campaign to Protect Rural England chief executive, said: “A lack of affordable housing is often seen as an urban problem, with issues of affordability in rural areas overlooked. It cannot be ignored any longer.
“Too much of our countryside is eaten up for developments that boost profits, but don’t meet local housing needs because of the ‘viability’ loophole.
“CPRE is calling for urgent action from the government to close the loophole to increase the delivery of affordable housing, otherwise rural communities risk losing the young families and workers which they need to be sustainable.”
