The UK is pretty much there on IPV6 - BT (and by extension anyone who uses BT's network, so, everyone except Virgin Cable and Kingston Communications in Hull) now offers native IPV6 - you get delegated a /56 (albeit a dynamic /56 allocation for most). The tricky part is router support - BT's own equipment supports it for the most part (Only the Smart Hub and Home Hub 5), but third party routers can be difficult - TPLink still only support /64 prefixes on their current firmware, and their firewall doesn't work properly when using their beta firmware that supports /56 prefixes. So - the infrastructure is there, but support is variable.
