Yes I was aware of the different providers and if I remember correctly, Plusnet and TalkTalk both offer FTTC in Stratford upon Avon, however, price wise it still looks like BT is the best cost option as I am already with them. I also have to consider that through BT I pay for an additional service, Call Sign, which allows a second phone number to be allocated on the same line. If I was to switch my phone service provider, in search of cheaper FTTC provision, then I would lose this hugely beneficial low cost option.
I suppose I could wait and see if/when O2 move into the market, but from what I have seen most BT competitors also limit upload speed to 2mbps and that's also not taking into account the limited capacity at each cabinet, unless that is scaremongering.
I have to say that I have been extremely happy with O2 but obviously the temptation of even higher speed is appealing!
