Your Draytek should be fine. You would connect the ethernet cable from the Openreach VDSL2 modem to the ethernet WAN port and away you go once you configure it for the service and your login details to your chosen ISP.
If you went with BT Infinity it might be wise to use their supplied Home Hub for a few days first, partly to make sure it works so would be available as a standby, and partly if you did need any CS help they would probably want you to be connected through it.
To be honest BT Infinity is fantastic value for money, but Customer Service if there is a problem may not be brilliant, and it could be subject to traffic management. We need some recommendations from others.
The one I'm with, IDNet, has a good reputation over the years, doesn't have traffic management, and reckons to have the capacity to give a decent speed all the time except just after midnight. (That's when its heavier downloaders schedule their runs).
For what I need the cost is comparable with BT. On higher packages it is a lot more expensive, as are most of the others.
