Hello mate and welcome to the forum.
I'll give you the same advice I give anyone, think carefully about this. Scaffolding is going down the pan. It's been burdened with over the top and ill thought out rules, wages are struggling and there's many good men out of work or unable to get permanent jobs.
If you really want to get into it, seriously, then your HGV license will come in handy. Phone every firm you can find or go down their yards and nag for a job. Mention your CSCS and most of all your driving license. Scaffolding is not like most jobs with CVs, interviews and long waiting, it's get down there and convince the boss on the spot you're worth hiring.
But seriously think about it, maybe better to progress and get your ADR for trucking and go tanker driving, good money in that.
