Kudzu is a problem in warm parts of the USA. As far as I am aware the UK is too cold for it to be rampant, yet.
Variegated Osmanthus, Privet or Eunonymous comes to mind, esp if in a raised bed. Photonia red robin if planted in the ground would work but I find it too loose to give any privacy.
Realistically I think you are looking at a conifer hedge or Beech. Bare root Beech should be very cheap at this time of year.
