Yes, it is, though its timings are PAL 50Hz field and 15625Hz line rather than CGA's NTSC-derived 60Hz/15750Hz. An early Multisync monitor should be able to sync to the Beeb's output, though such monitors are a rare breed these days. The Beeb's output is also composite sync where CGA is separate H and V, but a crude sync separator does the job. Somewhere I've got a box I made which allows a BBC's RGB output to be connected to a CGA monitor, and it only contains a transistor and some resistors and capacitors.

Unless there's an easy way to convert RGB to component - but then the only TV here with component in is a 29" Sony CRT so it might be a smidge big!

RGB to component is generally a straightforward matrixing job, so you might be able to enjoy big-screen BBC (or Sord, or Apple)!
Incidentally, CPC here supply all sorts of useful converter boxes. Component to RGB:

and RGB to VGA/XGA:

which would probably do better job than the OP's composite converter.
