the best way to look at the
nvq is this.
even if it costs you £550 for a osat, then do it because if it prevents you from working on a site in 2010, then think how much money you will lose that way.
i know it must really stick in the throat of all you time served tilers but, i'd rather lose £550 than a the possibility of all that future life earnings on a site as of 2010.
