As I say, I'll conceed if the RGS agree with you. The ordnance survey certainly mapped the islands, they mapped Bermuda as well.
As far as I can see from a quick search the correct term seems to be "The Normandy Archipelago"
If the OS isn't good enough for you, I'd say you're just being obtuse!
BTW - The Isles of Silly are also an archipelago, but still within the British Isles.
