Hi Karl,
I'm a member of Check-a-Trade, joined in July this year.
I joined at level one, it has not brought anymore work my way, when you get clients to fill in the card after each job, I explain to them what check-a-trade is about and only one so far had even heard of them. Do I think it's worth the money to be with them, jury is still out on that i'm affraid. Yes it says you have been vetted, checked etc, but if people don't even know that they exsist, then how is it doing me any good. I do have to admit check-a-trade did not try the hard sell on me etc, it was my choice to contact them and join, but not sure it is worth it to be honest.
