"Frozen north" being the balmy south in Manchester. B-)
The only dealings I've had with that lot was to get and renew my "Lorimar Letter". All my other tax dealings go through the local office, who send me my return. If no one is sending you a return, wriggle a bit you might fall through the cracks....
I actually opened the package containing the return for 2004/5 the other day and filed it along with the 2005/6 one. My accountant emails a .pdf version which I print, check, sign and post.
