Right, face plate is off and we are running!
Downstream speed is now 2048 kbps, and wait for it........ downstream noise margin seems to have settled around the 10.5 to 13.5 range (it still seems to be flitting - the poll interval is set at 10 secs - is this too short?)
What are my options given that I am technically incompetent in this sort of thing (but you might have worked that out for yourself!)
Sorry also meant to ask if there is any reason why I can't leave it plugged in with the face plate hanging off (though something tells me this is probably illegal)?

Just put the faceplate back on and noise margin is now in the 8 to 9 db range compared to the 3 to 7 I had earlier.

It shouldn't move more than 0.2db in a 10 second poll.
You seem to have a wiring problem and the fact that removing and putting back the faceplate seemed to have improved things suggests it might be the socket itself.
There's no problem or illegality in running with the faceplate off. The downside is it is untidy and any extensions you have wired into the socket won't work.

I have just sat and watched the stats and they have ranged from 7.5 db to 11.1 db in 60 seconds.
Doesn't sound like something I can moan at Sky about. Will BT do anything?
Must say I am really grateful for your assistance with this. There should be some sort of site where you can sign up and award beer chits to people who help you on forums. If there was, there would be a chit or two coming your way! Cheers.

If you are seeing changes like that in 60 seconds when connected to your test socket then there's little you personally can do.
It is almost certainly a line problem somewhere between (and including) the wiring in your socket and the exchange. If it is at the exchange then it is Sky's problem. If it is somewhere en route then it is BT's.
BT will work hard to correct a voice fault. Are you sure you can't hear an occasional hiss or crackle on the line? (Try jiggling your phone plug in the socket a couple of times). If you can then BT will sort this for free. Otherwise you can call them out under risk of a charge and if they find no fault (or that it is under your ownership, not theirs), they will bill you.
A virtual beer is fine with me. Your thanks is much appreciated.

Something has just clicked. My Line attenuation is 63.5 db and if I divide by the 13.8 figure quoted in the background reading you pointed me too then this says I am 4.6 kms from the exchange. However when I look at the distance from exchange calculator on dslzoneuk it says I am only 2.51 kms from the exchange! I have also checked this with some digital mapping software I have which confirmed 2.5 kms as the right answer.
Something isn't adding up here. Any pointers where I can go from here. Is it a call to tech support at Sky?
