The first one looks right, or at least what's on the website.
You could also try the sales one (sales@banks-europa.co.uk) in case there's someone other than Richard monitoring that email address, but Richard is more of a telephone person and the way most folks get in touch is to simply ring him up and talk through what you want. I'd check out the time difference from Greece/UK and give him a call in their opening hours.
