Almost all external insulation fitted under Tory scheme needs repair or replacing, report finds

Homeowners who took advantage of government programmes left with cladding likely to cause damp

Almost all the external insulation fitted under the previous government's energy efficiency scheme was installed so poorly it will have to be repaired or replaced, an investigation has found.

Thousands of homeowners who took advantage of the home insulation schemes have been left with incompetently fitted cladding that in some cases is likely to cause damp and mould.
