Thanks all for your replies, it's a real pain having these conflicts with workmen
They have agreed to come back and take it all up, lay it down correctly and glue the planks together which was previously not done - although that was a battle in itself as apparently they have done more floors than I've had hot dinners so they know what they're talking about, how sweet to watch them admit they got it wrong!
I'd spoken to the OFT today and apparently the fact that it was laid in the wrong direction was deniable as there was no proof that I'd asked for that, but as they hadn't used glue this shows they had not excercised reasonable care and skill and were therefore in breach of the services and goods act so at the very least they would have had to take it up and glue it together or pay the bill for somebody else to do it. 2 weeks til they come back so we'll see what happens then
If you have any similar problems I would certainly recommend looking at consumerdirect.gov.uk
