The UK has the draughtiest and oldest housing in Western Europe. And our gas boilers pump out twice as much carbon dioxide as all of the country’s power stations. Do we need to upgrade the UK’s homes? Why is our housing powering the climate crisis? And how can we make sure everyone’s home is warm, clean and green - whether we rent a flat or own a castle?
