all application for BVC is made through online, www.bvconline.co.uk

Good institutions for BVC will be:

Inns of Court School Of Law (City Law School)
College of Law
BPP Law School
Manchester University
Cardiff Law School

My suggestions before you apply for BVC:

1)apply for inns, extra point will be given to student who are already admitted to the inns or accepted for admission.
2) Work experience, or any BAR related experience will be good for you
3) Get a GREAT reference from your tutor/lecturer!!
4) Choose your institution wisely.

As long as u pass your LLB with 2.2, you'll have pretty decent chance to be admitted to any of the BVC institutions. However, please be reminded that places are limited, there will be some stiff competitions.

Good luck!
