We had been doing various jobs for a firm that works in various goverment est and universities etc. After five years of working for him, he asked me about the NICEIC. I told him we wasn't with them, his face was a picture, lol. He has always been happy with our standard of work and that was all that mattered to him and his clients.
I can see the point you guys are making though if it has lost you work. I don't believe we have but I may be wrong. Anyhow as pointed out above it's pretty irrelevent there are good and bad contractors under all the scheme's, there all just a rediculous requirement that proves nothing. The proof is in the pudding so to speak
