the health & saftey test will get you the CSCS card to get you on site. If yer wanna work as a tiler you will have to be qualified with in two years of getting your card. i was told if you have evidence that you working towards the NVQ they issue you with a blue card for an experienced worker. once you have an NVQ lvl2 you get a blue card for a skilled worker. you get a gold card for NVQ lvl 3

hope this helps
This is only if you wanna do site work
oh p.s
if you have been experienced for 5 or more years the NVQ 2 should be free, just a day's assesment
