Emergencies: 111, 999 and urgent care
When to call 999 vs 111, what urgent treatment centres are for, and how emergency care works before you're registered.
Medical emergencies in the UK are handled through a simple, free system: call 999 for life-threatening situations, 111 for urgent non-emergency advice, or visit an urgent treatment centre for injuries and illnesses that cannot wait for routine care. Whether you are registered with a GP or not, help is always available.
999 vs 111: Knowing When to Call
When to Call 999
Call 999 if someone is seriously ill or injured and their life is at immediate risk. This is for life-threatening emergencies only. Examples include severe chest pain, difficulty breathing, unconsciousness, major trauma from accidents, strokes, and severe allergic reactions. If you are unsure and believe someone is in danger, it is always safer to call 999—the call handler will assess the situation and tell you what to do next.
When you call 999, a call assessor answers and guides you through questions to understand your emergency. If an ambulance is needed, paramedics or community first responders will be sent. However, calling 999 does not always mean an ambulance will come—you might be advised to make your own way to A&E (Accident & Emergency) or to attend elsewhere if it is safe to do so. Both 999 and 111 lines are available 24 hours a day, 7 days a week, 365 days a year.
When to Call 111
Call 111 when you need urgent medical help but the situation is not life-threatening. Use 111 if you think you might need to go to A&E but the condition is not limb-threatening or critical. Examples include minor injuries that still need attention, sudden unfamiliar illnesses, infections, severe symptoms like high fever or unusual rashes, and situations where you are unsure what to do. If you are uncertain whether to call 111 or 999, call 111 first—the trained health adviser will ask questions about your symptoms and direct you to the right service.
The NHS 111 service is available both by phone and online. You can call the number 111, or access NHS 111 online at 111.nhs.uk to answer questions about your symptoms. For children under 5, you should always call 111 rather than use the online service. When you call or use the online service, you will be offered different options: a callback from a nurse, a telephone or video consultation with a clinician, or an appointment at A&E or an urgent treatment centre if needed. The 111 team can also help with emergency prescription supplies and dental emergencies.
Urgent Treatment Centres vs A&E
What Are Urgent Treatment Centres?
Urgent treatment centres (UTCs) provide urgent medical help when the situation is not a life-threatening emergency. They can diagnose and treat many common problems people attend A&E for, such as minor cuts, sprains, strains, broken bones, minor infections, burns or scalds, bites and stings, and rashes. UTCs are open at least 12 hours a day, every day, including weekends and bank holidays. Many operate 24 hours or near-24-hour schedules depending on local need.
To access a UTC, contact NHS 111 by phone or online first. The health adviser will assess whether a UTC is appropriate and, if so, can book an appointment for you or advise you to walk in. Some UTCs accept walk-ins without booking. When you arrive, you may have basic investigative tests such as blood tests, X-rays, or an ECG (heart trace). You do not need to be registered with a GP or have a fixed address to use a UTC. If you bring your NHS number it can help, but you do not need it. If the staff determine your condition requires hospital admission, you will be transferred to A&E immediately.
What Is A&E For?
A&E (Accident and Emergency), also called the Emergency Department, is the hospital department for major, life-threatening illnesses and injuries. A&E operates 24 hours a day, every day, though not every hospital has a full A&E department. Staff are highly trained in emergency medicine and have access to equipment and treatments for critical conditions. When you arrive at A&E, a nurse will triage (assess) you based on severity and you will be treated on a priority basis.
You should attend A&E or call 999 for life-threatening emergencies: unconsciousness, severe chest pain or pressure, major trauma, difficulty breathing, strokes, severe bleeding, and other critical situations. Do not delay—if you are unsure, call 999 and let the assessor decide. You do not need a referral from a GP or an appointment. However, if you arrive without calling 111 first, you may wait longer than if the hospital is expecting you. The NHS 111 team can book you an appointment time, notifying A&E so you avoid lengthy waiting room delays.
Emergency Care When Unregistered
One of the most important protections in the UK system is that emergency care is free and available to everyone regardless of whether you are registered with a GP or have been in the country long. You do not need a National Insurance number, proof of residency, or any immigration status to receive emergency treatment.
A&E and Ambulance Services
A&E treatment is completely free for everyone, including overseas visitors. If you call 999 and need an ambulance, ambulance services and emergency department treatment are provided free of charge and without any registration requirement. GP practices have a legal duty to provide emergency and immediately necessary treatment free of charge for up to 14 days to anyone in their practice area who is unregistered, refused registration, or rejected as a temporary resident.
Urgent Treatment Centres
As noted above, you do not need to be registered with a GP or have a fixed address to use a UTC. Simply contact NHS 111 by phone or online and explain your symptoms. You may also walk in to some centres without booking. Staff will ask for personal details and will help you access care. If you do not know your NHS number, that is fine—the centre can still treat you.
NHS 111
NHS 111 is also available to unregistered patients and is free. It is the entry point for urgent advice and can direct you to the right service. Some UTCs employ staff to help you register with a GP if you are unregistered, so using 111 and accessing urgent care is a chance to get into the system.
Practical Steps When an Emergency Happens
- Stay calm and assess whether the situation is life-threatening. If there is any doubt, call 999.
- If calling 999, be clear about the location and describe the problem. Answer the call handler's questions honestly and listen to their advice.
- If you are unsure whether it is an emergency, call 111. The adviser can escalate to 999 if needed.
- You can use NHS 111 online at 111.nhs.uk if you prefer not to call, though calling is better for complex situations or children under 5.
- If attending A&E or a UTC, bring any medicines or prescriptions you take with you. This helps staff understand your medical history.
- You do not need to bring a passport, visa, or immigration document to receive emergency care, though you may be asked questions about your residential status at non-emergency services.
- If you do not speak English fluently, tell staff when you arrive and you can request an interpreter, including British Sign Language.
Key Takeaways
The UK emergency system is designed to get you the right care fast, whether you need immediate ambulance response or advice on whether to attend hospital.

Urgent treatment centres offer a faster alternative to A&E for injuries and illnesses that are not critical. Most importantly, all emergency and urgent care is free and available to everyone in the UK, regardless of registration status or immigration situation. When in doubt, call 111 or 999—trained professionals are there to help you decide what to do next.
