Have only just managed to get on the phone with Sky as had a very busy day. Spoke to a very helpful guy who understood the situation and seemed very on the ball with broadband stuff. Basically plugged it into main socket, then test socket etc but there was barely any difference to my extension so i'm now synced at:
ADSL Link Downstream Upstream
Connection Speed 2802 kbps 253 kbps
Line Attenuation 45.0 dB 27.7 dB
Noise Margin 6.1 dB 19.1 dB
Which is enough of an improvement for me although the upload is very disappointing as long as I can use XBL with voice comms etc i'm not too bothered.
Now just need to wait for fibre
