Hi everyone.
Just to let you know how things turned out. An Openreach engineer called and did some work on the lines outside of the house and almost immediately our sync speed jumped up. After about 10 days, the DLM had the sync speed up to a steady 80mbps down and 20 mbps up which is what we had previosuly experienced.
The actual throughput speed fluctuated around 50ish down and 17-18 up and settled at 57mbps down (not good) and 17 mbps up (which is close enough to not worry me.)
Knowing that our line was now as close to perfect as copper can be, that we were less than 200M from the cabinet and having read some things about the Wifi hub improving wifi signal at the expense of throughputs I decided to try an old Dlink router in bridge mode (thanks to a post elsewhere by @KeithFrench ) with my Netgear Nighthawk R8000 in router mode doing the brain work.
Pretty straight forward set up and whilst maintaining the 80/20 sync speed, the throughputs have jumped to 70mbps down with the uploads staying level at around 17-18 mbps
In the end, openreach solved some issues with the lines and the new shiny wifi hub was also a big bottleneck on the connection.
I would like to thank @OCE_Chris @OCE_Debbie @KeithFrench for their help and support with this issue
