You may get work as a hairdresser here, but the wages will not be anything like what you can earn in the UK. You will not get Tax credits or benefits for you children, but check this out with the government websites. Your mother may still get her disability allowance.

There are English schools, but they cost! The Cypriot schools seem to be ok but not a patch on the UK education system. You must do your research well, especially with children. There are a lot younger families taking the plunge, best way is to start your own business, when you come.
