If you were getting someone else's leccy bill...
How long would it take you to notice?
I've just realised, that since I moved to a new flat 14 months ago, I've been getting someone else's electricity bill.
Well, the bill has the correct address, and the meter number on record with the supplier is the same as the meter number labeled as being connected to my flat. The catch is that the meter isn't connected to my flat, and is instead connected to another flat.
I must admit that I had my suspicions after the 1st bill, but the readings matched those on the meter - and unfortunately, the meters are kept in a locked room, and the management only allows supervised access. Only once I had a pretty strong suspicion something was up, did I approached the management and ask them to let me watch all the meters going round for 15 minutes or so.
