You need to book on to a 2 day refresher course with citb you don't need to be a working scaff, but still need deep pockets as it's yet another rip off idea to fleece the hard working scaff of his beer tokens , however saying all that I actually found the course to be rewarding and you come away with a couple of little extras on the card like alloy tower module and scaffold inspection, both are a piece of **** , the hardest part of the course is staying awake in class hope helps good luck
