On a crap day you'll get a traffic service if you ask for one (if you can first find a radar controller who works weekends, which you tend not to in my part of the country), but as there's nobody but you flying they won't be telling you much.
I have flown S-N and had a traffic service from Farnborough on a crappy weekday, lots of other traffic around that I knew about and where they were because I had traffic service but many of these guys knew nothing about me, then got handed on to Brize and BHX, not so uch traffic but still nice to have that reasurance!
