Forming a Limited company in Ireland is cheap and straightforward. That is compared to a GmbH in Austria or Germany where you need thousands of Euros in share capital just to form.[0]
Ireland uses the Euro, which might be an advantage over the UK with Pounds Sterling. No forex worries.
Ireland also has a low corporation tax rate of 12.5%
The only two trickier bits are setting up a registered address in Ireland (not P.O Box) and opening a bank account. Not insurmountable tasks, and various organisations can assist for a few hundred Euros.[1]
