Hi Emma , Lou at Cpc holding here ,congratulations on taking the plunge , firstly the subject of your daughters education The Spanish state school system is very good however your daughter must be fluent in Spanish prior to starting or she will fall behind and be held back at least one year . It has always amazed me how many English people simply put non Spanish speaking children into a state school and just hope for the best , obviously you are thinking ahead so if the language is a problem perhaps you should look at the private English schools which are not so expensive depending on the area you are going to .
You can do a degree course in Spain but again the universities are totally Spanish speaking and grant funding is not normally available .
The health service in the more cosmopolitan areas is brilliant and in my experience knocks spots of the U.K I have found the hospitals to be clean and well managed and the level of medical care to be fantastic once you are paying social security / national insurance both you and your daughter are fully covered .
The tax system in Spain is completely different to the U.K AND TO ADVISE PROPERLY ON THIS i WOULD NEED TO KNOW IF YOU WILL BE AN EMPLOYEE OR SELF EMPLOYED , I can tell you that there is not an expat tax credit system in place but their are tax allowances according to circumstances .
