If you employ people, you have a legal responsibility to make suitable first-aid arrangements for your workplace. This leads to the question: What Is the Legal Requirement for First Aid at Work?

However, the legal requirement for first aid at work does not mean that every employer must have the same number of first aiders, provide the same equipment or send employees on exactly the same first-aid course.

Under the Health and Safety (First-Aid) Regulations 1981, employers must provide first-aid equipment, facilities and suitable personnel that are adequate and appropriate in the circumstances.

The Regulations are deliberately flexible because workplaces are different.

A small office with five employees does not present the same risks as an engineering company employing 100 people. Likewise, a construction site, warehouse, school, factory or remote workplace may have very different first-aid requirements.

Employers therefore need to consider the circumstances of their own workplace and decide what first-aid provision is appropriate.

This is normally done through a first-aid needs assessment.

What Does the Law Say About First Aid at Work?

The main legislation covering workplace first aid in Great Britain is the Health and Safety (First-Aid) Regulations 1981.

Regulation 3 requires employers to provide adequate and appropriate first-aid equipment and facilities so first aid can be given to employees who are injured or become ill at work.

Employers must also provide an adequate and appropriate number of suitable people to provide first aid where required. A suitable person must have training and qualifications appropriate to the circumstances. Legislation.gov.uk

There is an important phrase running through the legislation:

“Adequate and appropriate in the circumstances.”

That is why there is no single legal number of workplace first aiders that applies to every employer.

The first-aid arrangements need to reflect the organisation.

What Is the Legal Requirement for First Aid at Work in Simple Terms?

For most employers, the legal requirement can be understood through several key responsibilities:

Assess the first-aid needs of the workplace.
Provide suitable first-aid equipment.
Provide appropriate first-aid facilities where required.
Have enough suitable people available to provide first aid, or an appointed person where that level of provision is appropriate.
Make sure first-aid cover remains available when needed.
Tell employees about the first-aid arrangements.
Review the arrangements when circumstances change.

The important point is that these requirements work together.

Having a first-aid kit does not automatically make a workplace compliant.

Neither does sending one employee on a first-aid course.

The employer needs an overall system that is appropriate for the workplace.

What Is a First-Aid Needs Assessment?

A first-aid needs assessment helps an employer determine what first-aid provision their organisation requires.

HSE’s current L74 guidance explains that employers should assess their needs according to the circumstances of their workplace. The current edition also emphasises considering employees’ mental health within that assessment. HSE

Factors to consider include:

The nature of the work
Hazards within the workplace
The number of employees
Previous accidents and incidents
The types of injury or illness that could occur
Working patterns and shifts
Lone workers
Employees working away from the main site
Multiple buildings, floors or work areas
The location of the workplace
Distance from emergency medical services
Holidays and absences among first aiders
Employees with particular needs
Members of the public or other non-employees
Whether additional first-aid equipment may be necessary

The assessment should reflect what actually happens in the business, rather than simply counting employees.

Is There a Legal Minimum Number of First Aiders?

There is no single statutory ratio that says every UK workplace must have one first aider for a particular number of employees.

This is an important distinction.

HSE provides suggested numbers of first-aid personnel, but these figures are guidance to help employers make decisions. They do not replace the first-aid needs assessment.

For lower-hazard workplaces, such as offices and shops, HSE guidance suggests:

Number of employees	Suggested provision
Fewer than 25	At least one appointed person
25–50	At least one EFAW-trained first aider
More than 50	At least one FAW-trained first aider for every 100 employees, or part thereof

For higher-hazard workplaces, HSE guidance suggests:

Number of employees	Suggested provision
Fewer than 5	At least one appointed person
5–50	At least one EFAW or FAW-trained first aider, depending on the likely injuries
More than 50	At least one FAW-trained first aider for every 50 employees, or part thereof

These numbers provide a useful starting point.

They should not be treated as universal legal minimums.

Your needs assessment may identify that you require more first aiders because of shifts, workplace layout, specific hazards or other circumstances.

Does Every Workplace Need a Qualified First Aider?

Not necessarily.

The Regulations recognise circumstances where an appointed person may provide appropriate first-aid cover instead of a trained first aider.

When deciding whether that is appropriate, Regulation 3 specifically refers to factors including:

The nature of the undertaking
The number of employees at work
The location of the establishment Legislation.gov.uk

This means a very small, low-risk workplace may not necessarily require an EFAW or FAW-qualified first aider.

However, an appointed person is not the same as a trained first aider.

What Is an Appointed Person?

An appointed person takes responsibility for the workplace’s first-aid arrangements where that level of provision is appropriate.

Their responsibilities can include looking after first-aid equipment and facilities and taking charge of arrangements when somebody needs professional medical assistance.

An appointed person does not automatically become a first aider simply because they have been given this role.

They should not be expected to perform duties that require first-aid competence unless they have received appropriate training.

Employers should therefore avoid treating an appointed person as a cheap alternative to a trained first aider where the needs assessment indicates that trained personnel are necessary.

What Is Emergency First Aid at Work?

Emergency First Aid at Work, EFAW, is commonly used where the needs assessment identifies a requirement for someone trained to deal with workplace first-aid emergencies.

The qualification normally involves one day of training.

Learners develop practical skills covering areas such as:

Assessing an incident
Managing an unresponsive casualty
CPR
AED use
Choking
Bleeding
Shock
Minor injuries

EFAW may be appropriate for many lower-risk workplaces.

The decision should still come from the needs assessment rather than choosing the shortest available qualification automatically.

What Is First Aid at Work?

First Aid at Work, FAW, provides more extensive training than EFAW.

The initial qualification is normally delivered over three days and includes emergency life-saving skills alongside a wider range of injuries and illnesses.

Depending on the qualification specification, training covers subjects including:

CPR and AED use
Choking
Bleeding
Shock
Burns and scalds
Fractures
Head injuries
Spinal injuries
Chest injuries
Eye injuries
Poisoning
Anaphylaxis
Asthma
Heart attack
Stroke
Diabetes
Seizures

FAW is commonly identified for larger or higher-risk workplaces where first aiders may need to respond to a wider range of emergencies.

You can find out more about our First Aid at Work training.

How Do You Decide Between EFAW and FAW?

Do not start by asking which course is cheaper or shorter.

Start with the workplace.

Consider what could realistically happen.

A small administrative office might mainly need people prepared to deal with common medical emergencies and relatively minor workplace injuries.

An engineering company may have risks involving machinery, serious wounds, crush injuries, burns or other trauma.

The second organisation may therefore require more comprehensive first-aid training.

HSE’s framework can also lead to additional training where workplace hazards require skills beyond the standard EFAW or FAW syllabus. The current L74 guidance specifically includes training requirements and first-aider competence within workplace provision. HSE

The qualification should fit the risk.

Do You Need More First Aiders to Cover Holidays and Sickness?

Possibly, and this is where simply using a headcount can become misleading.

Imagine a workplace with 40 employees.

The employer identifies that one EFAW-qualified first aider would normally be appropriate.

They train one person.

What happens when that employee is:

On holiday
Off sick
Working from home
Attending a meeting elsewhere
Visiting another site
On a training course
No longer employed by the company

Your first-aid arrangements need to work in practice.

Regulation 3 specifically addresses temporary and exceptional absence, allowing an appointed person to take charge in certain circumstances. However, employers should not design their normal first-aid arrangements around their trained first aider routinely being unavailable. Legislation.gov.uk

Planned absences and ordinary working patterns should therefore form part of the wider assessment.

What About Businesses Operating Shifts?

Shift patterns can significantly change the number of first aiders required.

Suppose a factory employs 90 people but operates continuously.

Having several qualified first aiders on the payroll may look adequate.

If they all work the same daytime shift, however, the business could have little or no trained first-aid cover overnight.

Employers need to think about when people are working, not merely how many first-aid certificates the company holds.

The same applies to weekends, evenings and seasonal working patterns.

What About Multiple Buildings and Large Sites?

The physical layout of a workplace should form part of the assessment.

One qualified first aider may be technically present somewhere on a large site, but that does not necessarily mean first aid can be provided quickly.

Consider:

Separate buildings
Different floors
Warehouses
Workshops
Outdoor working areas
Restricted-access areas
Remote sections of a site

A casualty suffering cardiac arrest or life-threatening bleeding needs immediate assistance.

The needs assessment should therefore consider whether first aiders and equipment can reach different parts of the workplace quickly enough.

What Is the Legal Requirement for Lone Workers?

Lone workers need to be considered within the employer’s first-aid arrangements.

That does not automatically mean every lone worker must hold an EFAW or FAW qualification.

Instead, assess the circumstances.

How would the worker summon help?

What hazards are present?

How far away are other people?

How quickly could emergency services reach them?

Do they travel between locations?

Could communication fail?

Would first-aid training help them manage an emergency?

For some organisations, training lone workers can be a very sensible outcome of the assessment.

The nearest workplace first aider may provide little practical assistance if they are several miles away.

What About Employees Working in Pairs?

Small teams working away from their normal workplace deserve similar consideration.

For example, imagine two employees regularly travelling together.

Only one has first-aid training.

What happens if the trained person becomes the casualty?

Training both employees may be a sensible solution.

This is not a general legal rule saying every member of a two-person team must hold a first-aid qualification.

It is an example of how a good needs assessment considers what could happen in the real world rather than simply satisfying a numerical target.

What First-Aid Equipment Does an Employer Need?

The law requires adequate and appropriate first-aid equipment and facilities. Legislation.gov.uk

There is no universal first-aid kit that suits every workplace.

The contents should reflect the needs assessment.

A low-risk office may require relatively straightforward first-aid supplies.

A workplace where life-threatening bleeding is a foreseeable risk may identify a need for additional equipment and appropriately trained personnel. HSE’s 2024 update to L74 specifically strengthened its guidance around life-threatening bleeding. HSE

First-aid equipment should also be:

Accessible
Clearly identifiable
Appropriately located
Regularly checked
Replenished when items are used
Checked for expired or damaged products where applicable

Buying equipment is only the first step.

People also need to be able to find it when an emergency occurs.

Is a First-Aid Room Legally Required?

Not every workplace needs a dedicated first-aid room.

Whether one is required depends on the circumstances and the first-aid needs assessment.

Where a first-aid room is provided under the Regulations, it must be accessible to stretchers and other equipment needed to transport patients. The room must also be appropriately signposted. Legislation.gov.uk

Larger workplaces and organisations with particular risks may be more likely to require dedicated facilities.

Do Employees Have to Be Told About the First-Aid Arrangements?

Yes.

This is an actual requirement within the Regulations and deserves more attention than it often receives.

Regulation 4 states that employers must inform employees about the first-aid arrangements, including the location of equipment, facilities and personnel. Legislation.gov.uk

In practical terms, employees should know things such as:

Where is the first-aid kit?

Who are the first aiders?

How do I contact them?

Where is the AED?

How do I summon emergency help?

This information could be provided during induction and reinforced using notices, signage, staff handbooks, internal systems or other appropriate methods.

Having excellent first-aid arrangements hidden away in a risk-assessment folder is of little use during an emergency.

What Is the Legal Requirement for First Aid for Members of the Public?

The Health and Safety (First-Aid) Regulations primarily concern first-aid provision for employees.

HSE guidance nevertheless recommends that employers consider non-employees when assessing first-aid needs. HSE

Depending on the organisation, this could include:

Customers
Visitors
Contractors
Students
Children
Sports participants
Volunteers
Members of the public

This consideration can be particularly important for schools, gyms, leisure facilities, shops, community organisations and visitor attractions.

The first-aid provision that makes sense for the organisation may therefore go beyond the strict employee-focused requirements of the Regulations.

What Is the Legal Requirement for Self-Employed People?

This part of the old article needed correcting.

The current Regulations do not simply say that every self-employed person has exactly the same first-aid duties as an employer.

Regulation 5 now refers specifically to a “relevant self-employed person” who conducts an undertaking of a prescribed description.

Where Regulation 5 applies, that person must provide adequate and appropriate first-aid equipment to enable them to render first aid to themselves while working. Legislation.gov.uk

The distinction was introduced following changes to health and safety duties affecting self-employed people.

Therefore, the simple statement:

“The First-Aid Regulations apply to every self-employed person.”

would be misleading.

Self-employed people who are unsure which health and safety duties apply to their particular work should check the current HSE guidance relevant to their activity.

Is an AED a Legal Requirement in the Workplace?

There is no general requirement within the Health and Safety (First-Aid) Regulations 1981 that every workplace must have an AED.

That does not mean employers should ignore defibrillator provision.

Whether an AED would be appropriate can be considered as part of the wider first-aid needs assessment.

Relevant factors could include:

Workforce size
Workplace location
Distance from emergency medical help
Activities taking place
People regularly using the premises
Existing emergency arrangements

Where an AED is available, people should know where it is and how to access it.

Importantly, anyone can use an AED during an emergency. A person does not need an AED certificate before using one.

Practical CPR and AED training can still help people become familiar with the equipment and build confidence before an emergency occurs.

Our guide to an AED Trainer explains how learners can practise this safely during first-aid training.

Does Workplace First Aid Training Have to Be HSE Approved?

This is another area where older website content can easily become outdated.

HSE no longer approves first-aid training providers.

The law changed in 2013, removing the previous HSE approval system for FAW training providers. The current version of Regulation 3 requires suitable first-aid personnel to have training and qualifications that are appropriate in the circumstances. Legislation.gov.uk

Employers are responsible for selecting appropriate training.

One route is to use a regulated qualification delivered through an awarding organisation.

First Aid and Safety Training delivers regulated first-aid qualifications through Qualsafe Awards, an Ofqual-recognised awarding organisation.

This provides employers with a clear quality-assured route when arranging workplace first-aid training.

How Long Are Workplace First-Aid Qualifications Valid?

EFAW and FAW qualifications are normally valid for three years.

A first aider who needs to remain qualified should complete the appropriate training before their certificate expires.

For FAW, this means completing the appropriate First Aid at Work requalification rather than assuming a short refresher course renews the certificate.

That distinction is important.

Is Annual First-Aid Refresher Training a Legal Requirement?

HSE strongly recommends annual refresher training for FAW and EFAW first aiders.

It is not the same as the three-year qualification or requalification process.

Annual refresher training helps first aiders maintain practical skills that may otherwise deteriorate when they are not regularly used.

Subjects such as CPR, AED use and casualty assessment benefit from repeated practice.

However:

Annual refresher training does not extend or renew the expiry date of an FAW or EFAW qualification.

Our guide to First Aid Refresher vs Requalification explains the difference in more detail.

Who Is Responsible for Monitoring First-Aid Qualifications?

The employer remains responsible for ensuring its first-aid provision is adequate and appropriate.

Good records should therefore identify:

Who the first aiders are
Which qualifications they hold
When certificates expire
Which locations they normally cover
Which shifts they work
Whether additional training is required
When refresher or requalification training is due

Do not wait until the only first aider’s certificate has expired before arranging their next course.

Forward planning helps prevent gaps in cover.

Does Having One Qualified First Aider Make a Workplace Legally Compliant?

Not necessarily.

Consider a manufacturing business with 80 employees.

It has one employee holding a current FAW qualification.

That sounds positive.

Now imagine the business operates 24 hours a day across several departments, while the qualified first aider works Monday to Friday from 9 am until 5 pm.

The qualification itself is not the problem.

The availability of suitable first-aid provision is.

This illustrates why first-aid compliance cannot be reduced to:

“We have a first aider.”

A more useful approach is:

Assess the need → provide appropriate equipment and facilities → train suitable people → ensure adequate cover → inform employees → review the arrangements.

When Should a First-Aid Needs Assessment Be Reviewed?

First-aid provision should continue to reflect the workplace.

Review the assessment when significant circumstances change.

Examples include:

Employing more people
Moving premises
Introducing new machinery
Changing working practices
Introducing new hazards
Adding shifts
Increasing lone working
Opening another site
Altering the workplace layout
First aiders leaving
A significant accident or emergency identifying a weakness

Periodic review is also sensible even where no major change has occurred.

A needs assessment completed several years ago may no longer represent how the organisation operates today.

What Happens If an Employer Does Not Provide Adequate First Aid?

The Health and Safety (First-Aid) Regulations form part of workplace health and safety law.

Employers should therefore treat first-aid provision as a legal responsibility rather than an optional employee benefit.

More importantly, inadequate arrangements can have real consequences during an emergency.

Imagine someone suffering cardiac arrest.

The AED is locked in an office and nobody knows where the key is.

Or a worker suffers life-threatening bleeding, but the nearest first aider is based in another building.

Perhaps the company has several first aiders, but none works the night shift.

These are not simply paperwork problems.

They can affect how quickly somebody receives potentially life-saving assistance.

The Legal Requirement Is the Starting Point

Businesses understandably want to know:

“What is the minimum we legally need?”

The law is important, but that question can sometimes lead organisations in the wrong direction.

Instead, ask:

What emergencies could happen here, and would our arrangements actually work?

Would someone know how to call for help?

Could a trained person reach the casualty?

Is suitable first-aid equipment available?

Do employees know where it is?

Is there enough cover when people take holidays?

What happens during a night shift?

What happens to a lone worker?

Could somebody respond to cardiac arrest or life-threatening bleeding?

Those questions are much closer to the purpose of a first-aid needs assessment.

First Aid Is Also a Life Skill

Workplace first-aid training has benefits beyond legal compliance.

Someone learning CPR because their employer needs another first aider may later use that skill outside work.

They might recognise a stroke in a relative.

They may help somebody who is choking in a restaurant.

Perhaps they will use a public-access AED during a cardiac arrest.

The employer’s legal responsibility creates the reason for providing workplace first aid.

Good training can create something more valuable:

people who have the confidence and practical skills to act when somebody needs help.

Get Help With Your Workplace First-Aid Training

Understanding the legal requirement for first aid at work starts with understanding your own workplace.

Consider your workforce, hazards, locations, shifts, lone workers, likely emergencies and existing first-aid arrangements.

Your needs assessment can then help determine whether you require an appointed person, Emergency First Aid at Work trained staff, First Aid at Work qualified first aiders or additional training for specific risks.

First Aid and Safety Training provides practical, regulated workplace first-aid qualifications for businesses and organisations across the North East.

You can explore our first aid training courses, book a first aid course or contact First Aid and Safety Training to discuss your training requirements.

For the underlying legal requirements, employers can refer directly to the Health and Safety (First-Aid) Regulations 1981 and the HSE First Aid at Work guidance, L74. Legislation.gov.uk
