Firstly, sorry if this is the wrong spot for this, I couldn't pick the best place.

We went in a competition a while ago to win solar panels for our house. Turns out, every entrant gets a free energy audit on their house! So we have someone coming at 10am on Saturday to check everything out. They'll also show us the panels we might win (I guess so we can buy them if we don't win lol). We also get a Bunnings voucher, hooray!

So I'm just wondering, what exactly is this guy gonna do? We're in a 1950's housing trust home, so I'm guessing there's plenty that we could do better. We already have a new roof with special insulation, it's double brick, we've got those roller shutter things on the front windows, and have gas water and heating.

What else are they gonna tell us we should do? Has anyone had one of these done before?
