First Aid at Work Explained: EFAW vs FAW and Which Your Workplace Needs

Every UK employer has to make some provision for first aid at work, but the law deliberately doesn't specify a single qualification every workplace must have. Instead it requires a first aid needs assessment, and the outcome of that assessment determines whether a workplace needs Emergency First Aid at Work (EFAW) trained staff, the fuller First Aid at Work (FAW) qualification, or both.

What EFAW covers

Emergency First Aid at Work is a one-day course covering the essential skills needed to provide immediate first aid when someone is injured or taken ill at work — managing an unresponsive casualty, CPR, choking, bleeding control, and basic shock management. It's designed to give a workplace first aider enough competence to stabilise a situation and keep someone safe until professional help arrives, without attempting to diagnose or treat the underlying medical problem.

What FAW adds on top

First Aid at Work is a more extensive, multi-day qualification that includes everything covered in EFAW plus additional training on a wider range of specific injuries and illnesses — things like fractures, spinal injuries, chest pain, and other conditions that need a broader first aid skill set than the emergency-only course provides. FAW is generally expected in workplaces with higher hazard levels, larger workforces, or where the nature of the work makes more serious injuries more likely.

How employers actually decide which one they need

The choice between EFAW and FAW isn't down to preference or course length — it's meant to follow directly from a formal first aid needs assessment. That assessment looks at the nature of the work and its specific hazards, the size and spread of the workforce, how far the workplace is from emergency medical services, the organisation's accident history, and any other workplace-specific risk factors. A small, low-hazard office with quick access to emergency services might reasonably conclude EFAW-trained staff are sufficient, while a workplace with higher hazards, more people, or a remote location is more likely to need FAW-qualified first aiders, in the same spirit as the general risk-based approach behind the HSE's five steps to risk assessment.

Certificate validity and refresher training

Both EFAW and FAW certificates remain valid for three years. Once a certificate expires, the individual is no longer considered a competent workplace first aider under the HSE's framework, so employers need to track expiry dates and rebook staff onto requalification courses before that three-year window closes. On top of the formal three-year cycle, the HSE strongly recommends annual refresher training in between, since practical skills like CPR technique are known to degrade with time if they aren't practised or revisited.

Where first aid provision fits alongside wider workplace safety

First aid provision doesn't sit in isolation — it's one output of the same risk assessment process that drives decisions on PPE, fire safety, and other workplace protections. A thorough risk assessment should flag not just what could cause harm, but what a workplace needs in place if harm does happen anyway, which is exactly the gap first aid provision is there to close. Employers who treat the first aid needs assessment as a genuine, documented exercise — rather than a box-ticking guess at "one FAW-trained person should be enough" — are in a much stronger position if provision is ever challenged after an incident.

Recording and reviewing first aid provision

Beyond training the right number of people to the right level, employers are expected to keep the first aid needs assessment as a living document rather than a one-off exercise — reviewing it whenever the workforce grows, the layout of the site changes, or the nature of the work shifts significantly. An out-of-date assessment that no longer reflects current staff numbers or site hazards can leave a workplace under-provisioned without anyone realising until an incident exposes the gap. Many organisations build this review into the same cycle as their wider health and safety audits, rather than treating first aid provision as a separate, standalone decision made once and then forgotten.

It's also worth remembering that first aid provision has to cover more than just the standard working day. Employers with shift patterns, lone workers, or staff working outside normal hours need to think through whether first aid cover is genuinely available whenever someone could be injured, not just during the nine-to-five period when it's easiest to staff. A trained first aider who's only ever on site during core hours leaves a real gap for early shifts, late finishes, or weekend working, and that gap should be identified and closed through the same needs assessment process rather than left as an unexamined assumption.

Frequently asked questions

Do all workplaces need First Aid at Work rather than the shorter EFAW course?
No — the level of first aid training needed depends on a formal first aid needs assessment. Lower-hazard workplaces may only need EFAW-trained staff, while higher-hazard or larger workplaces are more likely to need FAW.

How long is an EFAW or FAW certificate valid for?
Three years for both, after which the holder is no longer considered a competent workplace first aider until they requalify.

Is annual refresher training legally required between the three-year requalification?
It's strongly recommended by the HSE rather than a fixed legal requirement, to keep practical skills like CPR current between full requalification courses.
