I can't see that the .com adds any value or benefit. The brand is so well known that anyone with half a brain would know to add .com or .co.uk (which redirects to .com), and anyone who didn't would simply Google it.
I saw an EZY a/c the other day somewhere, I think it was at EDI or LPL, and remembered thinking it looked slightly different for some reason, that may have been the one.
