• Entitlement to NHS hospital treatment is based on ordinary residence’ in the UK, not nationality, having property in the UK or the payment of UK taxes or national insurance contributions- as has often been suggested in the press.
• Anyone not ordinarily resident in the UK is deemed an overseas visitor and is subject to the NHS (Charges to Overseas Visitors) Regulations 1989, as amended. These regulations place a responsibility on NHS hospitals to establish whether a person is ordinarily resident, or exempt from charges under one of a number of exemption categories, or liable for charges.
• New guidance has been issued to the NHS on how best to implement the charging regulations and most hospitals have an overseas visitors manager to oversee this. It is for hospitals to decide what evidence is acceptable in each individual case.
• Anyone who lives outside the UK for more than three months is no longer automatically entitled to free NHS hospital treatment. If the person is away on a one-off extended holiday, then they will continue to be fully entitled to free hospital treatment as soon as they return to live permanently in the UK. They will then be ordinarily resident again.
• An ex-pat who is not considered exempt from charges under the charging regulations will be charged for any treatment they receive during a visit to the UK.
• An ex-pat who resumes their permanent residence in the UK is exempt from charges immediately.
