OOPS - I checked, my 3 year old v cheap TV has no analog tuning.
I think that the composite video (BNC connector) should work if connected to the Yellow (usually I think) Phono video in connector on a TV. This is Monochrome only unless the BBC has been modified (one capacitor added or just a link on later models)
Sprow's webpages - how to series
How to connect a standard PC VGA monitor to a BBC micro (see conditions)
How to change the composite video output to colour
I am not an expert but the signals on VGA and SCART are not million miles apart.
