It is a really important question - how can you keep warm, protect the environment, while also lowering your costs? Today is Earth Day, and it comes at a time when six million families in the UK are facing an extra £320 to heat poorly insulated houses as energy bill soar.
An all-out drive to fix the problem has long been championed. Yet last year only 72,000 homes had insulation installed, compared to 2.3 million in 2012.
Friends of the Earth say free loft and wall insulation, starting in areas of high fuel poverty, would benefit eight million households.
