Indeed. I knew that, but my fingers typed the wrong thing I know that I knew it because I did 'wonder' when making my comments about bathroom lights - but then I decided that, even if it does have an 'upstairs', if it's a flat, it could well have a 'downstairs' bathroom! It was probably anticipating typing "(if there is an 'upstairs')", which is what I intended to type (and did type), that confused my typing fingers! Other than the correction of the typing, my comments remain the same.It's the downstairs that doesn't have an RCBO

Seriously. Your fingers operated on their own and typed up, when they should have typed down. Lucky you're not in bomb disposal. Before you jump up and down I am only taking the mickey here.
