"Each year the average householder in the UK spends around £620 on fuel
and power. That’s about £200 more than they need to. The energy we use
to heat our homes can escape through walls, roof, floors, windows and
doors if houses are not properly insulated. As well as being a waste
of money it also contributes to climate change by increasing the amount
of carbon dioxide released into the atmosphere."
