if you have your registration number or give them all your details they can check but most companies hate doing this which is why they say no card no job...
phone bircham,they give them your reg num.tell the lad before you go induction in case your sitting in it just to get sent home hope you get a result mate.
cheers for the advice lads ..got a copy from my old employer lucky enough .....maybe alot of work coming up later in the year on the BNFL site sellafield where i work ..
Scan your cards and keep them on your computer, that way you can always print a copy off and the employer can check if they're genuine (If he needs to)
