Not just 123reg but also LCN (though not on auto-renew)
I've been passed an email by a client who has a .co.uk registered with LCN ... the email encourages him to renew the .uk version of the domain or " ... all associated services on your domain name will stop working."
He doesn't have any services associated with the domain, but the tone of the email could easily spook non tech people into renewing. Not good.
Personally wouldn't touch LCN (domains or hosting) with a barge pole.
