One of the most common questions people ask is: how long do first aid courses take?
The answer depends on the type of course you choose, the level of qualification required, and whether you are completing initial training or refresher training. Some first aid courses can be completed in a few hours online, while others require several days of classroom and practical learning.

Why Is First Aid Training Important?
Before looking at course lengths, it is important to understand why first aid training matters.
According to the Health and Safety Executive, employers are responsible for ensuring appropriate first aid arrangements are in place within the workplace.
Official HSE guidance can be found here:

Proper first aid training helps employees:
- Respond quickly during emergencies
- Potentially save lives
- Reduce the severity of injuries
- Support workplace compliance
- Improve confidence in emergency situations
Many workplaces are legally required to have trained first aiders available depending on their risk level and workforce size.
How Long Does a First Aid Course Take?
The duration of a first aid course depends on the qualification being completed.
Emergency First Aid at Work Course Duration
The Emergency First Aid at Work course is one of the most popular workplace first aid qualifications in the UK.
This course typically lasts:
- 1 day
- Around 6 to 7 classroom hours
It is designed for lower-risk workplaces and provides basic emergency first aid skills.
Topics usually include:
- CPR and defibrillator awareness
- Recovery position
- Choking
- Bleeding control
- Shock
- Minor injuries
- Incident response
This course is ideal for appointed first aiders in smaller or lower-risk businesses.
The full First Aid at Work qualification takes longer because it covers a wider range of injuries, illnesses, and workplace scenarios.
The standard course duration is:
- 3 days
- Approximately 18 classroom hours
This qualification is typically required for higher-risk workplaces such as construction sites, warehouses, manufacturing environments, and larger organisations.
Training includes:
- CPR and AED use
- Fractures and spinal injuries
- Burns and scalds
- Seizures and medical emergencies
- Head injuries
- Asthma and allergic reactions
- Workplace incident management
Because of its depth, the 3 Day First Aid at Work qualification provides a more comprehensive level of workplace emergency response training.
First Aid Requalification Course Length
If your First Aid at Work certificate is due to expire, you can complete a requalification course instead of retaking the full programme.
A typical First Aid at Work requalification course lasts:
- 2 days
- Around 12 classroom hours
This allows qualified first aiders to refresh their knowledge and maintain certification.
How Long Does Online First Aid Training Take?
Some first aid awareness courses are available online and can often be completed in:
- 1 to 3 hours depending on the course
Online first aid training is useful for awareness purposes, refresher learning, or low-risk environments. However, some workplace qualifications still require practical classroom assessment to meet legal requirements.
