We don't have anything of that effect here in action currently. Our association is trying to get all tilers (tile setters) qualified and they're trying to get all site managers to only employ qualified tilers too I believe.
Apparently by 2010 you'll not be able to get on-site without the standard
NVQ qualification or older equivalent qualification.... but both routes would also need an extra health and safety test which afterwards gives you a card allowing you on-site. The Card Scheme is currently in-place but it's going to be tough to get all the tilers trained I feel.
With Gas plumbing we have to be CORGI registered and any attempts of Gas plumbing without one is pretty much against the law and deemed unsafe for obvious reasons.
Although I think a bad tiling job can have just as great risks. Perhaps not blowing up a property (which is rare i'm sure) but more common serious problems such as heavy tiles falling off walls... although not many serious injuries are reported, its still a serious problem as it does happen.
It's our associations job I feel to ensure that all tiling work is done to a good standard and push out the bad tilers or get them trained but nothing ever happens when a tiling job goes wrong really. In a bad case the
tiler would just get a bad name for a while and no more work from their local tile store or something which is annoying really as good tilers have to really prove themselves amongst the bunch somehow and its hard for a traditional
tiler to produce portfolios, websites and other marketing tools when they're half way through their career and work dries up a little due to our constant lust for foreign tilers that work cheaper and the tiling training centre boom.
We have a huge amount of training centres (see the A-Z at
Tiling Courses - Wall and Floor Tiling Course - Tiling NVQ - Tiling Courses & Tiling Course Companies) and no single governing body to govern the training or the tilers qualifications and skill level.
It's a bit crazy really here to be honest mate. it sounds not too dissimilar across the pond then.
