We are having an extension at the moment. Builder needs paying (less 5% at each stage) every four weeks. I'm assuming we'll do this by bank transfer as it's so much.
We've also asked the electrician who's doing the extension to rewire the rest of the house, for which he's charging us a reasonable £2k. He has said he'd like some of it in cash - is this normal? What method should I use to pay him the other bit? He doesn't seem in the least bit dodgy.
