Are British citizens from the OTs be entitled to free NHS treatment?
Eligibility for free NHS treatment is based on residence in the UK, National Insurance contributions, or payment of UK taxes, not on nationality. Visitors to the UK (whether they are British citizens or not) are charged for any NHS treatment they receive with certain exceptions: the exceptions include emergency care and treatment for some referred patients from those OTs with reciprocal health agreements with the UK. (The territories concerned are Gibraltar, BVI, TCI, Anguilla, Montserrat, St Helena and the Falklands). All visitors from the OTs receive emergency treatment from GPs and within hospital Accident and Emergency Departments free of charge whether or not there is a reciprocal health agreement.
