When I did it I had to present a portfolio of my work showing I could carry out the jobs they then came on about 3 of my jobs... even spoke to customers didnt take long but I assume it is a lot quicker these days and it is not worth the paper it is written on....
my son tells me that the site they are working on, a gang of eastern are rendering the mono. the agent said non of them have any cards. he asked to see the cards, they answer " when do you want the scaffold down? agent says "next week" he is told it is better to shut your mouth then.
i guess it is the same. my sons card needs to be renewed but when he saw the cost he stalled .
i have not got a cscs card i only have my apprentice indentures. they asked to see them in the Netherlands as they have had problems with British labour. that is the only time i have ever been asked to produce them.
