13 per cent of greenhouse gases emitted in the UK come from domestic heating, a similar level to emissions from cars.

The Conservatives’ answer to Labour’s radical Green New Deal during the election campaign was to work toward a net-zero carbon target by 2050, and now Boris Johnson will seek to get the necessary work underway with his majority in hand.

Insulation within UK homes is substandard, and Johnson has set about implementing a nationwide programme to upgrade them. His government has promised to spend £6.3 billion on the project, equating to £2,860 per household which will cover 2.2 million homes.
