So I dug around on CodeLook regarding the fibre rollout for Letterston. Seems like cabinet P1 and a bunch of other areas are set for FTTP. While I'm not getting my hopes up and it might be a mistake entry, I may end up having to go with BT or being limited for choice at the end of the day if FTTP does happen.
We wanted to ditch EE for TalkTalk when the rollout completes, though they don't seem to be doing an FTTP service. And neither does EE, although as it goes right now, we'd better off on at least BT since the customer service on EE has been irritating for us.
