hi mate like kgreigh says you need a level 2 to get the plastering card but you can do the site safety one day course and get a labourers card witch will get u onto site, most sites are ok with this card even if your plastering, but there may be some firms who wont let you, ive not heard of anyone being turned away,,you may hear different on here,,, its roughly £160 ish for the days course and you still have to do the heath and safty test £17.50 for the test then another £30 to get your card once youve passed the other 2 parts,,,
