Hi,
I can see on your website that the checkout page automatically scrolls down to the "No shipping method found" error message.
This is done automatically by the checkout system so that the customer can easily see what is wrong when there is a problem. That's specially useful on smartphones.
So your problem is not really the scroll. Your problem is that you have that shipping error message when you arrive on your checkout. I suppose that's because you configured shipping methods which require the address of the customer to display.
What you can do is simply turn off the "display errors" setting under the "shipping" view of your checkout workflow, in the Checkout tab of the HikaShop configuration.
Note however that the downside to this is that if the user has entered his shipping method and still no shipping method is found (because your shipping provider doesn't ship to his country or you didn't create a shipping method for his address for example), he won't see any error message. So the user might not know why he can't finish the checkout, which can be a problem.
A better solution in such a case is to keep that "display errors" setting activated, and change your checkout workflow to have two steps: a first step where the customer can login / register / enter his address and a second step where he can select his shipping method.
