I've been looking for a while at BT infinity packages and have been looking at other providers who use wholesale BT FTTC such as Zen, Eclipse, Sky and a few others but they all work out similar prices to Virgin if not more and most have usage caps.
No FTTP at the moment though
Been getting 30mbps on my Virgin connection that should have been doubled to 60mbps, so I think I'm gonna have to call them.
