I have a powerline adapter (Devolo units). There's no such restriction, as far as I know. My powerline transmitter and receiver are certainly on different circuits. > The way electrical wiring is done in the UK often means separate > floors are on different circuits, and in larger properties, each > floor might be on two (or more) circuits, making it difficult, at > best, to get the whole building networked this way.

Most houses in the UK are wired to a single phase, so everything is connected together at the consumer unit and powerline works just fine. If you have a specific problem, then there are DIN rail powerline units designed specifically to be mounted in the CU to spread the signal better over ALL the circuits. If your house has 3-phase wiring, which is unusual in the UK, then you may have a problem because powerline signals do need to be on the same phase.
