BT support is truly awful. Sky have much better support personally is never use BT after having an issue and having to deal with a truly pathetic call center.

oh dear..

the sky sales drone hacked me off by pushing far too hard for me to take up their TV package as well, so I ended up going with BT, and BT are offering £5pcm discount on sim-only mobile in addition (which I do want).

I hope I don't regret this choice.

In fairness I was with Talktalk for a couple of years and I thought they were fine, and my soon-to-be-Ex ISP is ranked highest on customer service and 'most trusted broadband provider' by various forums - o maybe I'm just lucky/different. YMMV.

You'll be fine

Yep.
