First Aid at Work | Requirements, Training, and Responsibilities

First aid at work is the immediate care given to someone injured or taken ill on the premises, and in the UK it's a legal duty under the Health and Safety (First Aid) Regulations 1981. Every employer must provide "adequate and appropriate" equipment, first aid courses for employees, and facilities.

After four decades of experience in health and safety from enforcement and consultancy to running teams of safety professionals in large organisations, I've seen every possible circumstance. In practice, many organisations don't approach first aid correctly. It's often an afterthought and, when something goes wrong, they find the first aid kit wasn't restocked for years, and no one has a clue who the qualified first aider is. I've helped many of large organisations understand it's importance and completely transform their process.

Getting first aid wrong carries significant consequences for employers, including Health and Safety Executive (HSE) enforcement and prosecution  and minor injuries becoming life-threatening ones because no one knew how to help. For the Directors and Managers who own this risk, this guide offers a clear guidance on what the law requires, how to run the needs assessment that sets your provision, and which training your workplace might need.

Key Takeaways

If you take nothing else from this guide, take this: first aid provision is a mandatory legal requirement. It's a non-negotiable. A first aid needs assessment is central to compliance, because it's the foundation for everything else such as how many people you train, at what level, and what equipment and facilities you put in place. From there, the level of training has to match your level of risk: First Aid at Work (FAW) for higher-hazard environments, Emergency First Aid at Work (EFAW) for lower risk ones, kept current through annual refreshers and three-yearly requalification.

At a Glance

• Provision is mandatory under the Health and Safety (First Aid Regulations 1981.
• Yours needs assessment sets your people, training level, kit, and facilities.
• Match the training required to your level of risk — FAW for higher hazard, EFAW for lower — and make sure it's current.

What Is First Aid at Work?

First aid at work is the immediate help given to someone who is injured or becomes ill while at work, either to preserve life and stop a condition worsening until professional medical help arrives, or to treat minor injuries that need no further attention. It's a regulated form of provision, not the casual assistance any of us might offer a friend or family member.

In a workplace context, the term covers three things working together: trained people, suitable equipment, and clear arrangements so everyone knows what to do. A colleague who collapses, cuts themselves badly, or suffers a cardiac arrest should get a fast, competent response from someone who knows what they're doing.

In the UK, formal first aid training falls into two main recognised qualifications:

First Aid at Work (FAW) — a three-day (18-hour) course covering a broad range of injuries and workplace emergencies, suited to higher-hazard environments.

Emergency First Aid at Work (EFAW) — a one-day course covering essential life-saving skills, designed for lower-risk workplaces.

Both sit under the same legal framework set by the Health and Safety Executive (HSE), and both teach the basics of basic life support, keeping someone alive and stable until the emergency services take over. Which one your people need depends entirely on your first aid needs assessment, which I'll come to shortly.

Why First Aid at Work Matters for Organisations

The scale of workplace harm is easy to underestimate until you see the figures. The Health and Safety Executive (HSE)'s 2024/25 statistics record around 680,000 workers sustaining a non-fatal injury, up from 604,000 the previous year, and 124 workers killed at work over the same period. Workplace injuries and ill health together cost an estimated £22.9 billion a year and account for 40.1 million lost working days.

Behind every one of those numbers is a person, and often a moment where a trained first aider made the difference between a manageable situation and a tragedy. That is case and point why first aid matters, but it isn't the only reason. There are several overlapping pressures every employer should weigh up.

Legal Obligations Under UK Law

The duty to provide first aid is not discretionary. Under the Health and Safety (First-Aid) Regulations 1981, every employer must make adequate and appropriate provision so that anyone injured or taken ill at work receives immediate help. Falling short is a breach of the law, with enforcement consequences.

Duty of Care to Employees and Visitors

Employers owe a duty of care not only to their own staff but, in many settings, to contractors, visitors and members of the public on site. A retailer or a venue with the public coming through the doors needs to factor those people into its first aid arrangements, even though the strict legal duty centres on employees.

Emergency Responses and Incident Outcomes

The first few minutes after a serious incident often shape everything that follows. A swift emergency response makes all the difference in the kind of emergency situations no workplace is immune to. In a cardiac arrest, for instance, every minute without CPR and defibrillation cuts the chance of survival significantly. A confident first aider on the scene, applying the right first aid techniques, and an accessible defibrillator, can be decisive long before an ambulance arrives. That is at the heart of an effective emergency response.

Reputational, Operational and Business Continuity Risk

A poorly handled workplace emergency can damage a business well beyond the incident itself — through HSE investigation, reputational harm, lost staff confidence and operational disruption. Strong first aid provision is, in plain terms, part of keeping the business running and protecting the people it depends on.

UK Legal Requirements for First Aid Provision

The governing legislation is the Health and Safety (First-Aid) Regulations 1981. The HSE expands on the detail in its L74 guidance and the INDG214 leaflet, both of which are worth keeping to hand. Between them, they set out what employers must do.

What "Adequate and Appropriate" Means

The law deliberately avoids a fixed national checklist. Instead, it requires provision that is "adequate and appropriate in the circumstances" — which is to say, proportionate to the actual risks of your workplace. What's adequate for a quiet office differs sharply from what a busy fabrication workshop or a chemical plant needs. That flexibility is deliberately intentional. It puts the responsibility on you to assess your own risk environments honestly.

Employer Responsibilities

In practice, every employer must provide at least:

• A suitably stocked first aid kit, reflecting the hazards identified in the assessment.
• An appointed person, or trained first aiders, available whenever people are at work.
• Information for all employees about the first aid arrangements — who the first aiders are and where the equipment is kept.

Record-Keeping and Reporting

While the 1981 Regulations don't mandate a specific accident book, keeping a record of incidents dealt with by first aiders is strongly recommended — it's invaluable when you review your provision, and it supports your wider obligations under RIDDOR to report certain injuries and dangerous occurrences. These duties are enforceable: the HSE can issue improvement notices, fines or prosecutions where provision falls short.

Understanding First Aid Needs Assessments

As we mentioned earlier, the first aid needs assessment is the foundation everything else rests on. Get it right and your provision follows logically. Skip it, and you're just running on guess work.

A first aid needs assessment is a structured review — closely related to your wider risk assessment — that determines how many first aiders you need, what level of training they require, and what equipment and facilities you must put in place. It sits at the very centre of of good workplace safety.

It doesn't have to be a formal written document, but I'd always recommend recording it — you may need to justify your decisions to an inspector, or to yourself after an incident. Work through the following factors:

• The nature of your work, and the hazards and risks it presents — machinery, chemicals, manual handling, working at height.
• The number of employees, plus shift patterns and any lone or remote workers.
• Your accident and ill-health history.
• The size and layout of your premises, and how spread out they are.
• Distance from emergency medical services and likely ambulance response times.
• Employees with known medical conditions — and, since the 2024 guidance update, mental health.
• Non-employees such as visitors, contractors and the public, where relevant.

As a rough rule of thumb, the HSE suggests that lower-hazard workplaces provide at least one first aider for the first 25 people on site, and higher-hazard workplaces at least one FAW-trained first aider for every 50. But I want to be clear: these are starting points, not the out-and-out rule. A cardiac arrest on the tenth floor of an office block isn't helped much by a first aider sitting on the ground floor. Your assessment, not a table, sets your real provision.

Types of First Aid Training in the Workplace

Once your needs assessment tells you what level of cover you need, you can choose the right first aid courses for your people. The main options break down as follows:

First Aid at Work (FAW)

This course overview starts with the most comprehensive option. The FAW course is typically three days of training covering a wide range of injuries, illnesses and workplace emergencies, from CPR and shock management to managing fractures, burns and life-threatening bleeding. It's the appropriate choice for higher-hazard workplaces such as construction, manufacturing and warehousing, and for larger lower-risk sites. CPR training and defibrillator use are a core part of this program.

Emergency First Aid at Work (EFAW)

The EFAW course is a one-day qualification covering the essential skills — the priorities of basic life support, CPR, choking, and dealing with an unresponsive casualty. These essential skills suit lower-risk environments such as small offices and shops, where the needs assessment points to a lighter level of provision.

Annual Refreshers, Certification and Requalification

Both FAW and EFAW certificates last three years, after which the first aider must complete a requalification course to renew their certification.  Crucially, because of strong evidence on first aid skill fade, it is recommended that all first aiders also attend an annual refresher in the years between. Skills decay over time without practice, and a first aider who last trained two years ago may hesitate at exactly the wrong moment. Work requalification keeps both competence and certification current.

Selecting the Right Level of First Aid Training

The choice between EFAW, FAW and additional specialist courses — such as mental health first aid or bleed control — should flow directly from your assessment, and from a quick look at any work course entry requirements. A good first aid training provider will also offer bespoke training tailored to your specific risks, whether delivered at your premises or at dedicated training venues. Some employers start staff on the work basics through short work training sessions before committing to a full qualification. Don't over-train a low-risk office for the sake of it, and don't under-train a high-hazard site to save a day. Match the training to the risk.

Roles and Responsibilities of Workplace First Aiders

Naming someone as a first aider isn't the end of the job — it comes with ongoing responsibilities that you must stay on top of. Clarity here prevents the awkward moment in an emergency where everyone assumes someone else is in charge.

Duties of a First Aider

A qualified first aider's role is to assess a situation safely, give immediate treatment within the limits of their training, and call for professional help when needed. They keep the casualty stable and as comfortable as possible until that help arrives, and they don't go beyond what they've been trained to do.

The Role of an Appointed Person

In the lowest-risk, smallest workplaces, the assessment may conclude that a trained first aider isn't required. In that case the law still expects an appointed person — someone who takes charge of the first aid arrangements, looks after the equipment, and calls the emergency services when necessary. An appointed person isn't a first aider and shouldn't attempt treatment beyond their competence.

Maintaining Equipment and Readiness

Responding to incidents is only part of the picture. A good first aider also keeps the first aid kit checked and restocked, makes sure any defibrillator is serviceable, and helps keep colleagues aware of the arrangements. Readiness is a habit, not a one-off.

First Aid Equipment and Facilities

Trained people need the right tools and spaces to do their job. Your needs assessment determines the detail, but a few essentials apply across most workplaces.

First Aid Kits and Standards

There's no legally prescribed kit, but the contents should reflect your assessment. A typical low-risk kit includes sterile dressings, plasters, triangular bandages, disposable gloves, safety pins and a guidance leaflet. The British Standard BS 8599-1 sets out recognised first aid standards for workplace kit contents and is widely used as a best-practice benchmark. Keep your medical supplies in date and restocked, and remember higher-risk sites may add burns dressings, eye wash and bleed control kits.

First Aid Rooms

Larger or higher-hazard workplaces may need a dedicated first aid room — a clean, accessible space stocked with equipment and, ideally, located near to where help is most likely to be needed. Whether you need one is, again, a question for your assessment.

Defibrillators (AEDs) and Their Growing Importance

An Automated External Defibrillator (AED) — sometimes called an external defibrillator — is becoming a standard feature of good provision, and rightly so. In a cardiac arrest, prompt defibrillation alongside CPR dramatically improves survival chances. Modern AEDs guide the user through the process with spoken instructions, and combined CPR and AED training gives first aiders the confidence to use an external defibrillator under pressure.

Accessibility and Visibility

Equipment that nobody can find is equipment that doesn't work. Kits and defibrillators should be clearly signed, easy to reach across the whole site — including upper floors and remote areas — and available at all times the workplace is open.

Common Challenges in Implementing First Aid at Work

In my experience, the same barriers to good safety and accident prevention come up again and again. Recognising them is half the battle.

• Misinterpreting the legal requirements. Treating "adequate and appropriate" as a fixed minimum, rather than a duty to assess properly.
• Underestimating risk. Assuming a workplace is low-hazard without genuinely working through the activities involved.
• Inadequate training coverage. Relying on a single first aider, who is then on holiday or off sick when something happens.
• Letting refresher training lapse. Forgetting that skills fade and certificates expire, leaving cover that exists only on paper.
• Distributed or remote workforces. Failing to provide cover for home workers, drivers and multi-site teams.

Most of these come down to treating first aid as a one-off purchase rather than an ongoing arrangement. Build it into your routines — induction, calendar reminders, regular kit checks — and the gaps close.

How First Aid at Work Is Evolving

First aid provision isn't static, and the last few years have brought meaningful change. Two developments stand out.

A Growing Focus on Mental Health First Aid

The 2024 update to the HSE's L74 guidance now expects employers to consider employees' mental health within the first aid needs assessment — a welcome recognition that wellbeing and safety aren't separate concerns. With work-related stress, depression and anxiety accounting for around half of all work-related ill-health cases, mental health first aid is moving from a nice-to-have to a serious part of the conversation.

Learning Technology, Defibrillators and Changing Workplaces

Alongside that, the same guidance update sharpened the focus on life-threatening bleeding and the kit needed to manage it. Learning technology is reshaping how first aid education is delivered too — blended and online learning for the theory, apps that locate the nearest defibrillator, and the reality of hybrid and remote working forcing employers to rethink how first aid cover reaches people who aren't on a single site. Continuous professional development, and a culture of ongoing learning that keeps first aiders current as guidance evolves, matters more than ever.

Frequently Asked Questions

What Is the Difference Between FAW and EFAW?

First Aid at Work (FAW) is a three-day qualification for higher-risk workplaces, covering a wide range of injuries and illnesses. Emergency First Aid at Work (EFAW) is a one-day course covering essential life-saving skills, suited to lower-risk settings. Your first aid needs assessment determines which is appropriate.

Is First Aid Training Mandatory for All Workplaces in the UK?

Every employer must make adequate and appropriate provision under the 1981 Regulations. In the lowest-risk, smallest workplaces this may mean an appointed person managing the arrangements rather than a trained first aider — but provision of some kind is always required.

How Many First Aiders Does a Business Need?

There's no fixed legal formula. As a guide, the HSE suggests at least one first aider per 25 people in lower-hazard workplaces and one FAW first aider per 50 in higher-hazard ones — but your needs assessment, accounting for layout, shifts and risk, sets the right number.

How Often Does First Aid Training Need to Be Renewed?

FAW and EFAW certificates last three years and must then be requalified. The HSE also strongly recommends an annual refresher in between, because first aid skills fade without regular practice.

What Should Be Included in a Workplace First Aid Kit?

Contents aren't fixed by law but should reflect your assessment. Typical items include sterile dressings, plasters, disposable gloves, triangular bandages and a guidance leaflet, with additions such as burns dressings, eye wash or bleed control kits in higher-risk settings. BS 8599-1 is a useful benchmark.

Do Small Businesses Need a Qualified First Aider?

Not always. A genuinely low-risk small business may only need an appointed person rather than a qualified first aider. But that conclusion should come from a proper needs assessment, not an assumption — even small workplaces have to make adequate provision.
