So after 7 or so weeks or issues I appear to finally have a stable connection (albeit still with high noise margin) and phone line.
When the engineers came out they could see errors on their test equipment but just couldn't pinpoint the actual fault. They assumed that the in house cabling was faulty (it was configured as junction box with the external cable jelly crimped to an internal cable, this ran to another set of jelly crimps on another internal cable that ran under the floorboards to the socket and was about 30 years old) so decided to replace from the incoming junction box to the socket with new cable.
At this point they thought all done, so got me to check everything and the fibre was still slow and looking rubbish but the phone was working at this point. They were about to leave (even though I wasnt really happy it was resolved) when the internet dropped and I lost dial tone again. Further tests and they decided to replace the cable from the telephone pole to the house. They couldnt run it in the same route as the old cable as that was installed through the wall before it was pebble dashed 20 years ago

, so they used the old Virgin media hole to run the cable into the house.
All in all the engineers were here for just over 3 hours and I now have this
Broadband Link Downstream Upstream
Connection Speed 40000 kbps 9999 kbps
Line Attenuation 15.9 dB 0.0 dB
Noise Margin 19.1 dB 22.22 dB
And it hasnt dropped once since Thursday.
