When to Call 999, 111, or 101: A Clear Guide for Every Situation

Why This Knowledge Matters

The UK has three primary emergency and non-emergency services numbers, each designed for a specific type and urgency of situation. Calling the wrong number means your call is handled by people who cannot dispatch the help you need, and in a genuine emergency those minutes matter. Understanding which number to call for which situation, and what to expect when you call, is basic safety knowledge that every UK resident should have.

999: For Immediate Life-Threatening Emergencies

Call 999 when there is an immediate threat to life or when a crime is actively occurring. 999 connects you to a call handler who can dispatch police, fire service, ambulance, coastguard, or mountain rescue depending on the nature of the emergency.

Call 999 for: someone who is unconscious or not breathing, or who has stopped breathing after a cardiac arrest. A fire that is out of control. A road traffic accident with serious injuries. A crime in progress, including burglary, assault, or robbery happening right now. Someone who is seriously injured. A person who appears to be drowning. A gas leak or explosion. Someone who has taken a dangerous overdose and is unconscious or losing consciousness. A mental health crisis where someone is in immediate danger of harming themselves or others.

When you call 999, the handler will ask which service you need and will ask you questions to assess the situation. Give your location first if possible, as calls can be traced but a spoken address ensures faster dispatch. Stay on the line and follow instructions. Do not hang up unless the handler tells you to.

If you cannot speak, call 999 and press 55 when prompted. This is the Silent Solution, used by people who cannot speak safely (for example because an attacker is nearby). Police will be dispatched to your location. You can also text 999 if you have previously registered your mobile with the 999 texting service (text register to 999 and follow the instructions while this is not urgent).

111: For Urgent Medical Advice That Is Not an Emergency

Call NHS 111 when you need medical advice or attention urgently but the situation is not immediately life-threatening. 111 is available 24 hours a day, 365 days a year, and connects you to a team of trained call handlers who can assess your situation and advise on the appropriate next step, whether that is self-care at home, seeing a pharmacist or GP, attending an urgent treatment centre, or in some cases calling 999 or attending A&E.

Call 111 for: symptoms that concern you and cannot wait until your GP is next available. Advice on whether a child's symptoms need immediate attention. Help deciding whether to go to A&E. Mental health concerns that need same-day assessment. Dental problems out of hours. Advice about medication queries.

111 can also book appointments at urgent treatment centres and out-of-hours GP services, reducing unnecessary A&E attendance. The NHS 111 online service provides the same triage for many situations and can be faster than calling during busy periods.

101: For Non-Emergency Police Matters

Call 101 for police matters that do not involve an immediate threat. This is the non-emergency police number for England, Wales, and Northern Ireland (in Scotland, use 101 or your local police number).

Call 101 for: reporting a crime that has already happened and is no longer in progress. Reporting concerns about suspicious activity. Seeking general police advice. Reporting damage to property. Noise complaints that have not been resolved through other routes. Seeking advice about a concern regarding someone's welfare that is not an immediate emergency. Asking for advice about a Prevent referral for concerns about radicalisation.

101 calls are charged at a flat rate per call regardless of duration, from both landlines and mobiles.

Other Important Numbers to Know

Beyond the three main numbers, several other helplines are worth knowing. The Samaritans (116 123) is available 24 hours for anyone in emotional distress. NHS 111 (press 2 after connecting) provides mental health crisis support in many areas. Crimestoppers (0800 555 111) allows anonymous reporting of crime information. The National Domestic Abuse Helpline (0808 2000 247) is available 24 hours. Childline (0800 1111) is free and available 24 hours for under-19s. The non-emergency coast guard number in coastal areas is via 999 (ask for coastguard).

Teach children these numbers as part of basic safety education. A child who knows to call 999 in an emergency, 111 for a medical concern, and has memorised at least one parent's mobile number is significantly better equipped to handle a crisis than one who has not been given this information.
