Every employer in the UK has a legal duty to provide adequate first aid. That much most managers know. What’s less well understood is what “adequate” actually means for a specific workplace, and why the answer can be very different for an office of 30 people compared to a warehouse running three shifts.
The distinction between EFAW and FAW is where it gets practical.
The legal framework
The Health and Safety (First Aid) Regulations 1981, one of the oldest pieces of health and safety legislation still in force, require employers to provide appropriate equipment, facilities, and trained personnel so that employees who are injured or become ill at work can receive immediate attention. The HSE’s Approved Code of Practice L74 supports this with guidance on what provision should look like.
Critically, there’s no prescribed ratio of first aiders to employees. Instead, the Regulations require a first aid needs assessment, a genuine evaluation of the specific risks in your workplace, the number and organisation of your employees, the history of accidents and incidents, and how close you are to emergency services. The outcome of that assessment determines what you need.
Emergency First Aid at Work (EFAW)
EFAW is a one-day qualification. It covers the core life-saving interventions, managing an unresponsive casualty, CPR, using an AED, managing choking, controlling bleeding, treating shock, burns and scalds, and recognising common medical emergencies like heart attack and stroke.
It’s designed for lower-risk environments where the likelihood of serious injury is relatively low and emergency services are accessible quickly: offices, retail settings, small businesses. In those environments, an EFAW-qualified first aider is typically sufficient. Certificates are valid for three years.
First Aid at Work (FAW)
FAW is a three-day course, broader and more detailed than EFAW. It builds on everything EFAW covers and adds management of specific injuries: head and spinal injuries, fractures and dislocations, crush injuries, eye injuries, poisoning and exposure to hazardous substances, anaphylaxis, chest injuries, and more complex assessment of unconscious casualties.
FAW is the right qualification for higher-risk workplaces, manufacturing, warehousing, logistics, construction, food production, engineering, and for operations where there are larger workforces, shift patterns, remote or dispersed sites, or greater distances from emergency services. FAW certificates are also valid for three years, with a two-day requalification course at renewal.
How the needs assessment determines which you need
The HSE’s guidance points to specific workplace factors as indicators that FAW is required rather than EFAW alone: physical hazards including machinery, working at height, power tools, chemicals, and extreme temperatures; a history of serious first aid incidents; remoteness from emergency services; large or complex sites; large workforces; and shift working with reduced staffing outside core hours.
For most industrial, logistics, warehousing, and manufacturing environments, FAW is the appropriate minimum for designated first aiders. EFAW may still have a role, as a supplementary qualification for lower-risk areas within a larger site, or for additional coverage, but it shouldn’t be the primary qualification in a high-risk operation.
Coverage is the piece most operations underestimate
The Regulations don’t just require qualified first aiders, they require first aid coverage whenever people are at work. If you run three shifts, you need first aid provision on every shift. If staff work on dispersed sites or travel regularly, provision needs to follow them. A single qualified first aider working 9–5, Monday to Friday, doesn’t cover a 24/7 operation.
Getting the qualification right matters, but making sure there’s always someone qualified available when your people are working matters just as much.

If you haven’t reviewed your first aid needs assessment recently, or if your workforce, operations, or risk profile has changed since you last looked, that’s worth doing before your next renewal cycle.
