While I dont have much of an issue with my connection I think I would likely move, just to try out something else/the improved latency on fibre.
That said VM will be doing 2gig connections at some point and if they can improve their network.......
Signed up for EE, thanks chaps. 100mb for £28.50 and I can upgrade to 500mb for an extra tenner if required. Speed guarantee is like 65mb on the 100mb or 300mb for the 500mb package. Annoyingly booked in for the day I am going on holiday but hopefully it all works out ok!100% FTTP. EE use BT, so get whatever is cheaper after cash back deals and any extras you want.
They did however upgrade my mobile plan temporarily to unlimited data which was a nice perk, so I can tether if required.
