In reply to StephenAS:
Hey, best thing to do it hire some pads - you might climb v4 indoors but outdoors is very different. Totally depends on what area of the Peak District you're in, you can search by area filter by bouldering and have a look for local stuff on the find crag section of the website.
Enjoy (and don't forget to clean your boots, mucky shoes is bad for the rock)
