Many core healthcare services are free under the NHS, which is a major benefit for expats living in the United Kingdom. For expats who have paid the Immigration Health Surcharge or otherwise qualify for NHS access, free services include GP consultations, emergency treatment at A&E, hospital care, surgery, maternity services, and treatment for infectious diseases. Expats in the UK can also access mental health services through the NHS, although waiting times may apply. Care provided by NHS hospitals and referrals from a GP to specialists are generally free at the point of use. However, expats in the UK should be aware that some services are not fully free, such as prescriptions in England, dental treatment, eye tests, and certain medical certificates, which usually involve fixed charges. NHS coverage focuses on essential and medically necessary care, which means expats can rely on it for most health needs, even if they choose private insurance for additional convenience or faster access.
