It may be different over in Eire and I hope Oftec do get it right there (my sister and much of my Dads' family are in the Boyle area) - but over here it seems that fellas turn up for assessments with no training attached (not Oftecs' fault they are there to assess your knowledge of the regs - with gas you have to build up a portfolio and then be assessed but there's no similar confirmation of hands on experience with Oftec)
its the same in ireland,turn up get your name right, tick a few boxs and away you go.pay them some money and you become a registered technician
