In a medical emergency in the United Kingdom, expats should act immediately and use the appropriate emergency services. For expats, if the situation is life-threatening—such as severe chest pain, difficulty breathing, heavy bleeding, or loss of consciousness—you should call 999 for an ambulance or go straight to the nearest Accident & Emergency (A&E) department. Expats in the UK can use emergency services regardless of immigration status, and emergency care is provided free at the point of use. For urgent but non-life-threatening issues, expats in the UK can call 111, the NHS non-emergency medical advice line, which operates 24/7 and can direct you to the right service. If possible, bring identification and any medical information, but do not delay seeking help. Knowing how emergency care works gives expats confidence and ensures they can respond quickly and effectively if a serious health issue arises.
