Every workplace has hazards—whether it’s a busy construction site, a warehouse, or a simple office environment. The purpose of a risk assessment is to identify those hazards, understand the level of risk they present, and put sensible control measures in place to prevent harm.
In simple terms, a risk assessment helps employers answer one key question:
“What could cause harm, and what are we doing about it?”
What is a risk assessment?
A risk assessment is a careful examination of your work activities to identify anything that could cause injury or ill health. It allows you to evaluate whether you have taken enough precautions or whether further action is needed to protect people.
This process involves identifying hazards, assessing the likelihood and severity of harm, and implementing control measures to reduce risks to an acceptable level.

The main purpose of a risk assessment
The primary purpose of a risk assessment is to prevent harm before it occurs. Rather than reacting to accidents, it encourages a proactive approach to managing workplace safety.
More specifically, risk assessments are intended to:
1. Protect employees and others
Risk assessments ensure that employees, contractors, visitors, and members of the public are safeguarded from workplace hazards. By identifying risks early, employers can take action to minimise or eliminate .
2. Support legal compliance
UK Health & Safety legislation requires employers to assess risks and implement appropriate control measures. A suitable and sufficient risk assessment demonstrates that you are meeting your legal duties and managing risks responsibly.
3. Identify hazards and control measures
Risk assessments help employers understand what hazards exist in their workplace and what could happen if they are not controlled. This allows businesses to implement effective control measures—following the hierarchy of controls where possible—to reduce or remove risk.
4. Promote sensible risk management
The goal is not to eliminate all risks, but to manage them in a practical and proportionate way. Risk assessments encourage businesses to focus on real risks—those that are most likely to cause harm or have serious consequences.
5. Improve workplace practices
Carrying out a risk assessment often highlights gaps in procedures, , or supervision. This helps employers improve how work is done and establish safer systems of work.
6. Prevent accidents and business disruption
By reducing workplace hazards, risk assessments can help prevent injuries, ill health, and incidents that may lead to lost productivity, legal action, or reputational damage.
Why risk assessments matter
Without risk assessments, employers may be unaware of serious hazards in their workplace. This can lead to accidents, enforcement action, and even prosecution.
Risk assessments also play a key role in building a positive safety culture. They show employees that is taken seriously and encourage them to engage with Health & Safety processes.
Who should carry out a risk assessment?
A risk assessment must be completed by a competent person—someone with the knowledge, experience, and understanding of the work activity and associated hazards.
This could be:
- An employer or manager
- A trained employee
- A professional health and safety advisor
The important factor is that the person carrying out the assessment can identify risks accurately and determine suitable controls.
What happens after a risk assessment?
Completing a risk assessment is not the end of the process. Employers must act on the findings by:
- Implementing appropriate control measures
- Communicating risks and controls to employees
- Providing necessary training and supervision
- Monitoring effectiveness and reviewing assessments regularly
Risk assessments should be reviewed if there are changes to work activities, following an incident, or at regular intervals to ensure they remain up to date.
Final say: What is the purpose of a risk assessment?
The purpose of a risk assessment is simple: to protect people by identifying hazards and managing risks effectively.
When done properly, it supports legal compliance, improves workplace practices, and helps businesses operate safely and efficiently.
Taking a proactive approach to risk assessment not only prevents harm but also demonstrates a clear commitment to Health & Safety.
