FTTC status said "available in some areas"
Great - you should use the number checker that you did before, and it said 70meg. Then you can order Fibre from anyone using your phone number - did you try Fibre or ADSL from Aquiss ?
But the 21 thing is a no
ISP doesn't list BT
No, it won't, but that's not a problem as the list isn't ISPs but those who run their own networks to the exchange. Only a few do this, and its known as LLU. BE/O2 did this.
It also states Zen Internet doesn't work at my address, when I had them five years ago
That means Zen LLU isn't at your exchange, but Zen can work over BT wholesale.
Your exchange has only BT wholesale's old system (20CN) which means any ISP using their network can only do upto 8megabit. This is why Aquiss say they can't serve you as they only work using BT wholesale's new network (21CN).
However if you can get fibre (and you want this) then you should be able to get any fibre ISP.
If you want another ADSL service, then the fact that TalkTalk network is present, means you could get a service from Viviaciti or Xilo/Uno. These companies can offer you similar speeds to your existing service with a quality product, but I don't think they're unlimited.
It depends what you want.
