Yes: under UK law, every employer must provide adequate first aid arrangements, and for many low-risk workplaces a trained Emergency First Aider at Work (EFAW) is the right way to meet that duty.
If you manage a team in the UK, you need a clear answer on first aid. The law does not give a single headcount rule for every business. Instead, it asks you to assess your risks and then provide suitable cover. This guide explains what the law says, who you need, and how to stay compliant.
What Does UK Law Say About First Aid at Work?
The key law is the Health and Safety (First-Aid) Regulations 1981. It applies to all employers, including small businesses, charities, and the self-employed who have staff.
The Regulations require you to provide “adequate and appropriate” equipment, facilities, and people. The Health and Safety Executive (HSE) enforces this duty in Great Britain.
Northern Ireland has similar rules, enforced by HSENI.
What “adequate and appropriate” means
The law does not tell you exactly how many first aiders to hire. You decide this by completing a first aid needs assessment. This assessment shows what your workplace needs.
You must be able to prove you completed it. Inspectors may ask to see it.
Do You Legally Need an Emergency First Aider at Work?
Not every business needs a certified first aider. Some only need an appointed person. The right choice depends on your risk level and size.
Here is the simple breakdown:
- Very low-risk, small workplaces: An appointed person may be enough.
- Low-risk workplaces with more staff: You usually need at least one trained first aider.
- Higher-risk workplaces: You need more trained first aiders, often at a higher qualification level.
What is an appointed person?
An appointed person looks after the first aid kit and calls the emergency services when needed. They do not give first aid treatment beyond basic emergency help.
This role suits small, low-risk offices. However, it offers much less protection than a trained first aider.
What is an Emergency First Aider at Work (EFAW)?
An EFAW is a trained and certified person who can respond to common workplace emergencies. The course lasts one day and is delivered by an HSE-compliant training provider.
EFAW training covers:
- Managing an unresponsive casualty
- Performing CPR and using a defibrillator
- Treating choking
- Controlling severe bleeding
- Helping someone in shock
- Handling minor injuries such as cuts, burns, and sprains
How to Complete a First Aid Needs Assessment
A needs assessment is the foundation of your legal compliance. It does not need to be complicated, but it must be honest and thorough.
Step-by-step checklist
Ask yourself these questions:
- What hazards exist? Consider machinery, chemicals, heights, and heavy lifting.
- How many people work here? More staff means a higher chance of incidents.
- Who is at risk? Include employees, visitors, contractors, and members of the public.
- Do any staff have health conditions? Think about epilepsy, diabetes, or heart conditions.
- Where do people work? Remote sites, multiple floors, and lone working all need extra thought.
- How far is the nearest hospital? Longer response times mean you need stronger on-site cover.
- Do you operate shifts? You need first aid cover during all working hours.
Review your assessment regularly. Update it when your workplace, staff numbers, or activities change.
How Many First Aiders Does Your Business Need?
The HSE gives guidance, not fixed rules. Use the table below as a general starting point for your planning.
| Workplace Risk | Staff Numbers | Suggested Cover |
|---|---|---|
| Low risk (offices, shops, libraries) | Fewer than 25 | At least one appointed person (a trained first aider is better) |
| Low risk | 25–50 | At least one first aider trained in EFAW |
| Low risk | More than 50 | One first aider for every 100 employees |
| Higher risk (construction, manufacturing, warehouses) | Fewer than 5 | At least one appointed person |
| Higher risk | 5–50 | At least one first aider trained in EFAW or First Aid at Work (FAW) |
| Higher risk | More than 50 | One first aider for every 50 employees |
These figures are suggestions. Your own assessment may show you need more.
Remember to plan for absence
First aiders take holidays, fall sick, and leave jobs. Always train extra people so your cover never drops to zero.
Many managers train one or two more staff than the minimum. This is a smart and low-cost safety net.
EFAW vs FAW: Which Course Do You Need?
Two main qualifications exist for workplace first aiders. Each suits a different level of risk.
Emergency First Aid at Work (EFAW)
- Length: 1 day
- Best for: Low-risk workplaces such as offices, shops, and small businesses
- Focus: Emergency situations and common injuries
First Aid at Work (FAW)
- Length: 3 days
- Best for: Higher-risk workplaces or larger organisations
- Focus: Everything in EFAW, plus a wider range of injuries and illnesses
Your needs assessment tells you which course fits. If you are unsure, ask a qualified first aid training provider for advice.
Legal Duties Beyond First Aiders
Training people is only one part of your duty. The law also requires you to provide the right equipment and information.
Your essential checklist
- A suitably stocked first aid kit that is easy to reach
- Clear signs showing where the kit and first aiders are
- A notice listing the names and locations of your first aiders
- Accident records kept in an accident book
- Information for all staff, including new starters, about first aid arrangements
- Regular checks to keep kit contents in date
If your workplace has a higher risk, you may also need a separate first aid room.
Don’t forget the defibrillator question
The law does not currently force every workplace to have a defibrillator (AED). However, many businesses choose to install one. Fast defibrillation greatly improves the chance of surviving a cardiac arrest.
EFAW training teaches your staff how to use an AED with confidence.
Do Self-Employed People and Small Teams Need First Aid Cover?
Yes, in different ways.
If you employ staff: You must follow the full regulations.
If you are self-employed with no staff: The Regulations do not require you to provide first aid for yourself. Still, the HSE strongly advises you to carry a basic first aid kit and consider training.
If you work with the public: The HSE strongly recommends including non-employees in your first aid planning. Customers, visitors, and clients can have accidents on your premises too.
Do You Need to Cover Employees Working Remotely?
Your duty of care still applies when staff work away from your premises. The extent of your duty depends on the situation.
For home workers, you are generally not expected to provide first aid equipment at their homes. For lone workers, travelling staff, or those on client sites, you should assess the risks and give them suitable first aid kits and guidance.
What Happens If You Ignore First Aid Rules?
Breaking the Regulations can cause serious harm, and the consequences go beyond a fine.
Potential outcomes include:
- Enforcement action from the HSE or your local authority
- Prohibition or improvement notices that disrupt your business
- Unlimited fines and, in serious cases, prosecution
- Civil claims from injured employees or visitors
- Higher insurance costs and reputation damage
Most importantly, poor first aid cover puts lives at risk. A trained first aider can make the difference in the first critical minutes of an emergency.
How Long Does EFAW Certification Last?
An EFAW certificate is valid for three years. After that, your first aiders must retrain to stay qualified.
Annual refresher training is not a legal requirement, but the HSE strongly recommends it. Short yearly sessions help your first aiders keep their skills sharp and their confidence high.
Track your expiry dates carefully. Set reminders at least three months before each certificate ends, so you can book training in good time.
Common Mistakes Employers Make
Many businesses fall short by accident. Avoid these frequent errors:
- Skipping the needs assessment or never updating it
- Relying on one first aider with no backup for absences
- Letting certificates expire without noticing
- Ignoring part-time, shift, or weekend workers when planning cover
- Using an out-of-date first aid kit with expired items
- Choosing a non-regulated training provider that offers weak or unrecognised courses
Fixing these issues is simple and inexpensive. It also strengthens your legal position.
