CSCS has got NOTHING to do with your Practical work it is not a trade card But it has got EVERYTHING to do With Health & Safety At Work and that is it the idea is that you have to show the site manager your card before starting work on a site contreolled by CDM regs in reallity in the 8 years i have held a CSCS Gold card NOT ONE site has asked to see it and on a Wimpy Jobe that i offered the card as evidence of my competence they rejected it and i had to undertake Wimpy induction training (1 1/2 hours) so i could go into a completed house to do a 20 minuite warranty job for a boiler manufacturer
