Thank you Andrew, very much appreciated for you help on this. Like you suggested originally I should have ordered and regraded but lesson learnt!

Let me know if you manage to get an update from OR

Thanks
Shane

Regrade to what? Both Andrew and myself have both come to the same conclusion, that your line is in all likely hood 400+ meters long, and thus too long for G.Fast, so you would have been very lucky to get better than what you currently have.

Count yourself lucky you get great VDSL speeds.
