There are four recognised categories of child abuse — physical, emotional, sexual, and neglect — and being able to recognise the signs of each is the first step in protecting a child. Abuse is rarely obvious. It shows up in small changes: a child who becomes withdrawn, an injury that does not add up, a fear of going home. Knowing what to look for is what turns a vague worry into a child getting help.
This guide explains the four types of child abuse, the signs to watch for, and what to do if you are concerned.

The four categories of abuse
UK safeguarding guidance recognises four main categories:
1. Physical abuse
Deliberately causing physical harm to a child — hitting, shaking, throwing, burning, poisoning, or otherwise causing injury. It also includes fabricating or inducing illness in a child. Possible signs: unexplained injuries, injuries in unusual places or in a pattern, injuries that do not match the explanation given, flinching, or reluctance to remove clothing.
2. Emotional abuse
The persistent emotional maltreatment of a child that damages their emotional development — constant criticism, humiliation, rejection, threats, or making a child feel worthless or unloved. It is present in most other forms of abuse but can occur alone. Possible signs: being withdrawn or anxious, lacking confidence, being overly eager to please, delayed development, or extremes of behaviour.
3. Sexual abuse
Forcing or enticing a child to take part in sexual activities, whether or not they are aware of what is happening, and whether or not there is contact. It includes online sexual abuse and child sexual exploitation (CSE). Possible signs: age-inappropriate sexual knowledge or behaviour, physical signs, becoming secretive, or a sudden change in behaviour around a particular person.
4. Neglect
The ongoing failure to meet a child’s basic physical or psychological needs — food, shelter, clothing, hygiene, supervision, or medical care. Neglect is the most common form of abuse. Possible signs: being consistently dirty or hungry, unsuitable clothing, poor hygiene, untreated health problems, or being left alone or unsupervised.

Wider forms of harm
Beyond the four categories, safeguarding also covers harms that have become more prominent:
- Child criminal exploitation (CCE) and county lines — grooming children into crime, such as drug running.
- Child sexual exploitation (CSE) — a form of sexual abuse involving an exchange or power imbalance.
- Online abuse — bullying, grooming and exploitation carried out through the internet and social media.
- The impact of domestic abuse — children living with domestic abuse are recognised as suffering harm.
Signs are indicators, not proof
An important caution: the signs above are possible indicators, not proof. A single sign rarely means abuse is happening, and children can show these signs for other reasons. Your job is not to diagnose or investigate — it is to notice, take it seriously, and pass the concern on.
What to do if you are concerned
Follow the same clear sequence used across safeguarding children:
- Recognise the possible signs, or listen if a child discloses.
- Respond calmly — listen, reassure, do not promise secrecy or ask leading questions.
- Record what you saw or were told, factually and promptly, in the child’s own words.
- Refer to your Designated Safeguarding Lead without delay — or call 999 if a child is in immediate danger.
If you are ever unsure, share the concern anyway. It is always better to check than to stay silent.

Frequently asked questions
What are the four types of child abuse?
UK safeguarding guidance recognises four main categories of child abuse: physical abuse (deliberately causing physical harm), emotional abuse (persistent emotional maltreatment that damages a child’s development), sexual abuse (forcing or enticing a child into sexual activities, including online abuse and child sexual exploitation), and neglect (the ongoing failure to meet a child’s basic physical or psychological needs). Neglect is the most common form.
What are the signs of child abuse?
Signs vary by type: physical abuse may show as unexplained injuries or injuries that do not match the explanation; emotional abuse as withdrawal, anxiety, low confidence or extremes of behaviour; sexual abuse as age-inappropriate sexual knowledge or a sudden change in behaviour around a person; and neglect as being consistently dirty, hungry, poorly clothed or unsupervised. These are possible indicators, not proof, and children can show them for other reasons.
What is the most common type of child abuse?
Neglect is the most common form of child abuse. It is the ongoing failure to meet a child’s basic physical or psychological needs — such as food, shelter, clothing, hygiene, supervision or medical care — and its signs include being consistently dirty or hungry, wearing unsuitable clothing, poor hygiene, untreated health problems, or being left alone or unsupervised.
What other forms of harm does safeguarding cover?
Beyond the four categories, safeguarding covers wider harms including child criminal exploitation (CCE) and county lines, child sexual exploitation (CSE), online abuse such as bullying and grooming through the internet and social media, and the impact of living with domestic abuse, which is recognised as causing children harm.
What should I do if I think a child is being abused?
Recognise the possible signs or listen if a child discloses; respond calmly by listening and reassuring without promising secrecy or asking leading questions; record what you saw or were told factually and promptly in the child’s own words; and refer to your Designated Safeguarding Lead without delay, or call 999 if a child is in immediate danger. It is not your job to investigate — only to recognise, record and refer, and to share a concern even if you are unsure.
