I thought it'd be worth finding out the defintive answer to this question which everyone seems to have different answers to, so after speaking with SEAT UK customer care I have the following...
For the LCR (and other 1.8T cars):-
Cambelt - Change belt at 120k or 4yrs, whichever is soonest
Tensioner & roller - Check for wear at service
Auxilary drive belt - Check for wear at service
Waterpump - No service interval defined.
Regarding cambelt, I believe it's also checked at 60k, 80k and 100k for wear
Cheers!
