I’m not used to letting just anyone into my house to look around, but I got a knock at the door a few days ago from a member of the government’s Living Greener team. He happily dug out my ladder and braved the spiders in my roof space to have a look at the insulation. He also organised for us to have a home sustainability assessment, which will mean we can get our hands on up to $10k to make our home more energy and water efficient.
