England's increasing housing affordability problem, widely described as a 'housing crisis', has become a major public and political concern in recent years. The proportion of social housing has been shrinking for 40 years but there is no political appetite - at least under the current government - to reverse this. Policies are instead addressed at making some private housing more affordable and at increasing access to owner occupation by allowing more social tenants to buy their homes. The government has increased its control over the financial affairs of social landlords, who are responding by concentrating on those areas of activity where control is less stringent.
