, which was launched in March last year by the government under Rishi Sunak and aims to help around 300,000 households with the cost of installing it.
As part of the scheme, homes can apply for cash to upgrade insulation in solid walls – as well as cavity walls, which are easier to insulate. But so far, just 816 out of a potential 7.7 million eligible households have been fitted with solid wall insulation. Climate change think-tank E3G claimed that installers are reluctant to carry out installations because it means they have to pay their workers to complete a PAS 2035 qualification before they are able to do the work.
Mr Dyson said: “The Conservative government have left a legacy of shambolic home insulation initiatives like the Great British Insulation Scheme. Others who have applied for support with solid-wall insulation have claimed that energy companies have told them that they do not offer this product through the scheme.
“If the government wants to help people then they need to sit down with energy companies and come up with a plan.”
