I have UK Virgin Cable TV and also get God Channel thrown in. Amusing for a laugh. (Even my JW father finds its commercialism Pharisaical.) I couldn't find any other religious channels on Virgin Cable, but I know Sky has more in its basic package.
There are also some Muslim channels on Sky under the "cultural" section, perhaps also available on UK cable.
After God Channel, the next closest I can get to religious programming on my current UK cable subscription (apart from the Internet) are the New Age/psychic/ghost shows which regularly screen on 'Living'-type channels. Usually with a disclaimer "for entertainment purposes only" (which many conveniently ignore).
There are also traditional Christian Sunday shows in the UK, such as Songs of Praise, but these are a far cry from the US variants.
