As we have said

If you have done all you can to eliminate your own wiring, and now you've tried a new router. Then next step is an engineer to attend and do some testing, and hopefully one with some actual ADSL knowledge.

In the mean time any sensible ISP would have asked if you don't mind them slowing you down to try and make the connection at least perform a little better, i.e. return you to the speeds you had at the start of this.

I recall establishing something about Sky, but I honestly can't remember what and I probably managed to get lost somewhere along the way. I know what I'm like

According to EE earlier, both OR Engineer visits were sent for a broadband fault and not a landline fault, so I'm not exactly sure where this leaves me now to be honest.
I will probably call them back a bit later as the "couple of faults" they found earlier will of been escalated to the fault management team and it saves me waiting up to 48 hours for them to call me

Since calling EE a while ago, the did a line test that reset the router and when it established a connection, it was just over 9dB I'm currently on 4.4bB nearly 3 hours later. I just can't seem to get them to listen to me and I suspect that every time the exsisting fault is opened up under a new number, they are going through the same elimination process as before minus the OR Engineer visits. I hope that I am wrong though.

The WBC 21CN kit is used by millions of broadband customers, so not likely to be a problem with that.

There may be a poor joint in the exchange, or in the mile or two of wiring to the home, or even in the home.

Sure

But OP stated that things were fine with Sky and I was just considering the possibility of an issue at the exchange end. Although, obviously, a line fault may have developed anywhere coincidentally after the migration.

Do you mean that the downstream SNRM went from over 9dB to 4.4dB during almost 3 hours of a continuous DSL connection?

The NM was over 9dB and dropped to 4.4dB and I've just had two re syncs. 1st set it back to 9dB and the 2nd up to 16.1dB but a lot more stable at the moment. I'm expecting this to drop again and trigger a re sync.

All figures are Downstream and I'm now on

That's the result of noise on line.

Remember, ISP and DLM only sets the Sync-time Target NM and has no truck with the NM's subsequent drifting during the connection session; that's entirely down to the variation in noise.

Is the noise likely to be in the higher BB frequency or will I hear it on a Quiet Line Test?
I'm unsure why I've been moved from ADSL2+ though. Unless its more stable

Depends on the type of noise. If line is quiet then no, an am radio may help identify if its something like a power supply close to the adsl modem

Deja vu - I think we've been here before...

Best of luck with the EE people if you call them later
