the_constructor coughed up some electrons that declared:

I am thinking of changing my ISP but am a little concerned who to go to.

Has Talk Talk improved over the last 12 months and do they have call
centres in GB...?

TIA

Don't know. But I am with Andrews and Arnold (aaisp.co.uk) and they are
*very* clueful. Not the cheapest - but here are a couple of examples of
calls from me to them over the last few years:

a) Me: Phones AAISP, lady answers in 15 seconds:
Me: My links gone dead, is it you or me?
Her: We're having a problem, engineers are rebooting something.
Me: Ok, that's all I need to know, I'll wait it out.
10 minutes later, all is well.

b) [Upgrade to ADSL-MAX, the 2Mbit/s cap wasn't being removed after the
physical link settled down to 6Mbit/s - waited 3 days]

Me, by email: blah blah, cap still in place;
Them in a couple of hours: Could you wait one more day?
Me: OK
[Next day] Me [still by email]: Nope, still broken, could you ask BT to fix
it?
Them [hour or two later]: Please bear with us.
[Later, within a day IIRC]: BT Engineer calls my mobile;
BT bloke: Yeah, this happens sometimes, I've reset some widget at our end.
Are you in a position to test it.
Me: Sure, give me a moment to ssh into my home system...
Me: Yes, that's running at about 6Mbit/s - thanks!

In summary - not cheap, not there outside of business hours, but when you do
call them, you do get to speak to intelligent people who don't ask you to
reboot Windows, which in itself is worth the cost!
