More than 30,000 households left with defects after ‘catastrophic failure’ of Tory government schemes

Members of parliament have called for the Serious Fraud Office to investigate the UK’s home insulation sector, after thousands of householders suffered ruined homes, big financial losses and months of disruption from the “clear and catastrophic failure” of two Conservative government schemes.

More than 30,000 households were left with defects, some of them severe, including mould, water ingress and damage to the fabric of walls, with about 3,000 dwellings so badly damaged they presented immediate health and safety risks to occupants.
