Working for non uk company. Irl/NL. PAYE NI contributions,

Can anyone tell me how you go about ensuring your national insurance contributions are kept upto date if you are working for a non UK haulier? Can you still claim child tax credits if your paye is for another country. Any info greatly appreciated. Not doing it yet only looking.

If you are working for the Dutch, as a rule they employ you thru a UK Agency so you atill pay UK tax and NI out of your wages. This is the way Nedexco and such like do it as far as i know.
