I've just swapped out my old Xyzel modem for a newer model and it looks like I've got a much improved SNR. My line rate was closer to 15.5Mbps before and it's already jumped to 18.00... It looks like there is quite a bit more room for improvement if my SNR is 13dB.

Any thoughts on how long it can take for the line to adjust to the new modem and potential speed improvements? I'm with Plusnet and I've asked if it would be useful for a line reset, given how it looks like it's hitting a banding threshold at the moment.

Code:
VDSL Port Details       Upstream         Downstream
               Line Rate:      5.324 Mbps       17.999 Mbps
    Actual Net Data Rate:      5.296 Mbps       18.000 Mbps
          Trellis Coding:         ON                ON
              SNR Margin:        6.2 dB           13.0 dB
            Actual Delay:          0 ms              0 ms
          Transmit Power:        7.1 dBm           8.9 dBm
           Receive Power:      -10.2 dBm         -17.6 dBm
              Actual INP:        0.0 symbols      54.0 symbols
       Total Attenuation:        0.0 dB          27.2 dB
Attainable Net Data Rate:      5.296 Mbps       25.907 Mbps

No idea what SNR and all that is but got a nw router when I renewed my TalkTalk and internet seems to be flying now. WiFi is much faster than it was before.

Ask Plusnet for a DLM reset, it looks like your line is banded to 18,000Mbps.

Ta, did that yesterday morning as it happens and they said it was indeed banded. Do you know how long it normally takes to lift the banding (do I need to force a resync, I haven't tried as don't want to confuse DLM)?

I'm not sure tbh. But from what I've read it should be pretty quick, a week maybe?

DLM should do it for you, I'd leave it a while and see if it moves. :)
