Not only are schools free in Ireland, but daycare for younger children, too, if you're working. Tuition fees are lower. And there are LOADS of social workers who cut their teeth in England and then moved back home, so you'll be in good company in getting your qualifications approved. However, Ireland can be quite "old fashioned" compared to England, especially in entrenched views of gender roles and everyday misogyny and racist microaggressions, but I did live in the north west so perhaps Dublin is different.
