Which TV package are you on, and which series are you asking about? It matters...
S1 was shown on one of the ITV spin-off channels (ITV2/3/4, I forget which - but it's immaterial) last week and has 30days CatchUp availability off the back of that.
S1 is also available as a boxset which will be included if you're on Maxit/XL.Full-House TV tier, but won't be available otherwise.
S2 E1 was broadcast last night, but doesn't look to be loaded onto VoD as yet - E2 is shown tonight.
The ITV branded app (home > Apps > All apps > ITV) seems to reflect the same, except that S2 E1 is available now.
