how recently did you pass? the place you sat your exams has 10-15 working days to process and send the paperwork on to their certification body who in turn have 10-15 days from receipt of them to process their bit and download your pass to Gas Safe Register who then add you to the register of qualified people, the certification body also send your certificates to you the same day the send email to GSR, contact where you did the exams, and chase for an answer they will say the cert body is to blame for the hold up, ask for the phone number, if they are tellig the truth they will give you the number if they are lying snd they are causing the delay they will tell you they will chase it up for you (and send them off quickly) they wont want you to phone their cert body and cause a stink if they havent sent the stuff off yet
