What does the Coalition’s Green Deal mean to the taxpayer?

A loft insulation job worth £1,200 costs the taxpayer £2,700 after the cost of the government’s red tape has been added on. And the power companies, which were allowed to put their bills up to pay for insulation and boiler swaps, have raked in £870 million but only done work worth £420 million. So it’s a nice little earner for them.
