What Is the Number to Call for Medical Advice in the UK?

When you or someone close to you feels unwell and you are not sure what to do, knowing which number to call can make a real difference. The UK has several medical advice and emergency services, each suited to different levels of urgency. Whether it is the middle of the night, a bank holiday, or you simply cannot reach your GP, understanding your options helps you access the right help at the right time. For readers trying to judge severe dental symptoms specifically, this guide to tooth infection symptom patterns may also be helpful.

NHS 111 is the right number to call when you need medical advice urgently but the situation is not a life-threatening emergency. This includes situations such as:

• You are unsure whether your symptoms require urgent attention

• Your GP surgery is closed and you need advice that cannot wait

• You need to find an out-of-hours GP, urgent treatment centre, or pharmacy

• You have a health concern that has come on suddenly and you do not know what to do next

• You need urgent medical advice for a child and your usual GP is unavailable

You do not need to have a specific diagnosis in mind before calling. The NHS 111 service is designed to help you work out what to do, not to require you to have already figured it out.

NHS 111 is not an alternative to 999 in a genuine emergency. If at any point during a call your symptoms suggest a life-threatening situation, the 111 service can arrange an ambulance for you.

NHS 111 advisers — including nurses, paramedics, and other trained clinicians — can help with a wide range of health concerns, including:

• Assessing symptoms you are worried about

• Deciding whether you need to be seen urgently or whether it is safe to wait

• Directing you to the most appropriate service (such as a pharmacist, GP, or urgent treatment centre)

• Helping you find NHS services near you, including out-of-hours GP services and mental health crisis lines

• Arranging a call back from a clinician where needed

• Arranging emergency services if your condition deteriorates and becomes life-threatening

NHS 111 is not able to offer a formal diagnosis, prescribe medication in every situation, or guarantee a particular clinical outcome. The service works as a triage and navigation tool to get you to the right care as efficiently as possible.

When you call 111, a trained call handler will answer and ask you questions about your symptoms. These questions follow a clinical assessment tool that helps identify the most appropriate next step for your situation.

Depending on your answers, you may be:

• Given self-care advice to manage your symptoms at home

• Directed to a local pharmacy for treatment of a minor condition

• Referred to your GP for a routine or urgent appointment

• Directed to an urgent treatment centre or walk-in centre

• Given an appointment at A&E to reduce your waiting time

• Connected to a local out-of-hours service

• Called back by a nurse or clinician for further assessment

• Sent an ambulance if the situation is considered urgent or life-threatening

If your symptoms worsen while you are waiting for advice or a callback, do not wait. If the situation has become life-threatening, call 999 immediately.

In England, you can access NHS 111 online at 111.nhs.uk. The online service asks you questions about your symptoms and provides guidance similar to the telephone service. However, there are important limitations to be aware of:

• The online service may not be suitable for young children, and for some ages you will be directed to call instead. Check the site for current age-related guidance before using it on behalf of a child.

• If your symptoms are severe or you are in significant distress, call 111 by telephone rather than using the online tool, as telephone contact allows faster assessment and, if necessary, an immediate emergency response.

• The online tool is available at any time and can be useful when symptoms are not urgent and you want to assess next steps.

If you are in any doubt about whether online access is appropriate for your situation, call 111 directly.

Understanding when to use each number is important for both your own safety and the efficient operation of emergency services.

Always call 999 — not 111 — if you believe someone's life is in immediate danger. Do not search online, complete a form, or wait for a callback if a situation has become life-threatening.

Call 999 immediately if someone:

• Is not breathing or has stopped breathing

• Is having a suspected heart attack (such as chest pain, pain spreading to the arm or jaw, shortness of breath, sweating)

• Is showing signs of stroke (facial drooping, arm weakness, speech difficulty — remember the NHS FAST test)

• Is unconscious or cannot be woken

• Is having a severe allergic reaction (anaphylaxis)

• Has a serious injury following an accident

• Is experiencing severe breathing difficulty

• Is in any other situation that appears immediately life-threatening

The 999 service dispatches ambulances and coordinates the emergency response. Do not call 999 for conditions that are urgent but not life-threatening — this helps ensure the service is available for those who need it most.

If you need medical help outside your GP surgery's opening hours and your concern cannot wait until the practice reopens, you have several options:

1. Call NHS 111 — the service operates around the clock and can direct you to an out-of-hours GP, urgent treatment centre, or appropriate local service.

2. Use NHS 111 online (England only) — suitable for less urgent concerns where you want guidance before deciding your next step.

3. Visit a walk-in centre or urgent treatment centre — suitable for injuries and illnesses that need prompt attention but are not emergencies, such as minor cuts, sprains, skin infections, or high temperature.

4. Speak to a pharmacist — pharmacists can offer clinical advice on a wide range of minor conditions and medicines-related questions without an appointment. Many pharmacies also participate in the NHS Pharmacy First service in England.

5. Go to A&E — this should be reserved for serious conditions that cannot be safely treated elsewhere. If you are unsure, calling 111 first is often the most efficient route.

If your concern is urgent dental pain, it may also help to compare NHS and private emergency fees and review practical steps for accessing NHS dental care.

NHS service arrangements vary depending on where you live in the UK. It is important to use the correct service for your location.

NHS 111 is available by telephone and online. Call 111 or visit 111.nhs.uk.

NHS 24 provides the urgent out-of-hours medical advice service in Scotland. You can reach NHS 24 by calling 111. NHS 24 also has an online symptom checker at nhs24.scot.

NHS 111 Wales is available by telephone. Arrangements and service availability in Wales should be verified against current guidance at 111.wales.nhs.uk, as some details may differ from the English service.

Northern Ireland does not use NHS 111. For urgent medical advice that is not an emergency in Northern Ireland, contact your GP out-of-hours service or the relevant local trust. For emergency care, call 999. Residents of Northern Ireland should check current guidance through the Health and Social Care (HSC) system for up-to-date contact information.

Having certain information ready before you call 111 can help the call handler assess your situation more quickly:

• Your name, date of birth, and address

• The name and date of birth of the person the call is about, if different

• A brief description of your symptoms, including when they started and whether they are getting worse

• Any relevant medical history, such as long-term conditions or recent operations

• A list of any medicines you are currently taking

• Your GP surgery name, if known

You do not need all of this information before you call — if the situation is urgent, call straight away.

It is not always easy to judge the severity of a medical situation, particularly when you are frightened or in pain. If you are uncertain:

• Call 111 — the service is specifically designed to help you make that judgement. Call handlers are trained to identify whether a situation needs an emergency response.

• Call 999 if you believe the situation may be life-threatening and you do not feel you can wait — it is generally safer to call 999 and be advised to seek a lower level of care than to delay emergency help.

If you call 999 out of genuine concern, emergency teams can assess the situation and direct you appropriately. Emergency services are staffed by professionals who understand that medical situations can be frightening and difficult to assess without clinical training.
