The government's "green deal", which begins on Monday, aims to plug the gaps in 14m of Britain's leaky homes, making them cosier, cheaper to heat and producing less climate-heating carbon emissions. Yet severe doubts are swirling around the programme like a bitter winter wind, some even whipped up by the government's own analyses.
