An overseas visitor is someone who is not ordinarily resident in the United Kingdom. Eligibility for free NHS hospital treatment is based on residency status and the relevant charging regulations, rather than nationality alone.
People who do not normally live in the UK may be charged for some NHS services unless they fall within an exemption category or are otherwise entitled to free treatment under the regulations.
If you are visiting the UK, we recommend that you have appropriate travel or medical insurance to cover any healthcare costs that may arise during your stay. If you hold a valid Global Health Insurance Card (GHIC) or European Health Insurance Card (EHIC), please bring it with you, as it may help determine your eligibility for certain healthcare services.
