Your children are entitled to the same free education as British children – although you may choose to send your children to a private school if you wish.
This will depend on the length of your permit. If you enter the UK on a work permit for less than six months, neither you nor your family will usually be covered by the National Health Service. You are not required to take out private health insurance, but it is wise to do so.
Where you are in the UK on a work permit lasting more than 6 months, you and your family here as your dependants are eligible to free health care provided by the National Health Service.
