I typed ‘number of U.K. homes insulated’ into Google - top item was from the Govt.
‘At the end of 2020, 14.3 million properties had cavity wall insulation (70 per cent of properties with a cavity wall), 16.6 million had loft insulation (66 per cent of properties with a loft) and 772,000 had solid wall insulation (nine per cent of properties with solid walls).’
Everything on the first page was in the same vein. Clearly, Insulate Britain use Google. Did you?
……and grants are available to home owners and even some private tenants for those without who wish to get.
Thise numbers above hardly spell a picture of a majority of homes with nothing do they?
