SIG have just paid me a visit. They're very convincing and say it's your last chance, it has to be today, and so on, all they want to do is take a look at the loft, it will take 30 seconds. I asked for more information but they didn't have anything to give me. They implied they were working on behalf of the energy companies but had nothing official to show for it. I was persuaded to say OK to a later appointment, then thought better of it and when they came back I told them to go away. I know I wouldn't have ended up being scammed but it worries me how easily I might have let someone into my home, just to have a look. Yikes. Kate
