Which First Aid Course Does My Workplace Legally Need?

If you employ people, you are legally required to provide first aid cover. That much is clear. What is far less clear to most employers is which first aid course their staff actually need, and that uncertainty is where a lot of businesses get stuck. Book the wrong course, and you have either overspent on training you did not need, or worse, left a gap that would not stand up if the HSE ever asked.

This guide answers the question plainly, so you can work out exactly what your workplace requires before you spend a penny.

What does the law actually say?

The law is less prescriptive than most people expect. The Health and Safety (First Aid) Regulations 1981 require every employer to provide “adequate and appropriate” first aid equipment, facilities and people. Notice the wording. It does not say every workplace needs a fully qualified first aider, and it does not name a specific course. Instead, it puts the responsibility on you to assess what is adequate and appropriate for your particular workplace.

That assessment is called a first aid needs assessment, and it is the thing that decides which course you need. The right training for a quiet accountancy office is genuinely different from the right training for a busy construction site, and the law expects you to reflect that.

What decides which course I need?

Three things, mainly: how risky your workplace is, how many people you employ, and the particular hazards of what you do.

A lower-risk workplace, think offices, shops, most retail and hospitality, generally needs a smaller number of people trained to a foundation level. A higher-risk workplace, think manufacturing, construction, warehousing, or anywhere with machinery, chemicals or working at height, needs more first aiders, trained to a higher level, because the injuries that can happen there are more serious.

So the honest answer to “which course do I need” is usually one of three.

The three courses most workplaces choose

Emergency First Aid at Work (a one-day course). This is the right choice for most lower-risk workplaces. It covers the essentials, a person who is unresponsive, not breathing, bleeding, choking or in shock, and it qualifies someone to be your appointed workplace first aider for three years. For a typical office or shop, this is very often all the law requires.

First Aid at Work (a three-day course). This is the fuller qualification, and it is the right choice for higher-risk workplaces or larger teams. It covers everything the one-day course does, then goes further into a wider range of injuries and conditions, including those more likely to occur in industrial or higher-hazard settings. If your needs assessment points to higher risk, this is the course that keeps you compliant.

First Aid at Work Requalification (a two-day course). If you already have qualified first aiders whose three-year certificates are coming up for renewal, they take this shorter course rather than the full three days. It is the cost-effective way to keep an existing first aider current.

Course	Length	Best suited to	Certificate
Emergency First Aid at Work	1 day	Lower-risk workplaces such as offices, shops and hospitality	3 years
First Aid at Work	3 days	Higher-risk workplaces such as construction, manufacturing and care, or larger teams	3 years
First Aid at Work Requalification	2 days	Renewing an existing First Aid at Work certificate before it expires	3 years

You can see all three side by side, with durations, who each one suits, and the actual price per person, on our first aid at work training page. We publish the prices openly there, so you can budget before you get in touch.

How many first aiders do I actually need?

There is no single legal number, but the HSE gives sensible guidance based on risk and headcount. As a rough guide, a low-risk business with fewer than 25 staff may need only one appointed person or one Emergency First Aid at Work qualified first aider. A higher-risk business, or a larger one, will need more, and more of them trained to the fuller First Aid at Work level.

The key point is that this is your judgement to make and to document. Keeping a written record of your first aid needs assessment is what demonstrates you have met your duty, and it is the first thing that would be looked for if there were ever a question.

How do I carry out a first aid needs assessment?

It is more straightforward than it sounds. You do not need a specialist to do it, and writing it down need only take a page. Work through these four questions:

1. How risky is our work? Be honest about the hazards. An office is low risk; a workshop with machinery, a kitchen, or a site with working at height is higher risk, and that pushes you toward the fuller qualification.
2. How many people do we employ, and how are they spread out? More staff, shift patterns, multiple floors or separate sites all mean you need more first aiders so that someone trained is always present.
3. Are there any specific risks or vulnerable people? Think about particular hazards, lone workers, members of the public, or settings where children or people with medical conditions are present. These may call for additional training on top of general cover.
4. What cover do we need across holidays and absence? One first aider is not enough if they are the only one, because leave and sickness will leave you uncovered. Plan for at least one spare.

Write down your answers and the decision they lead to. That record is your evidence that you have met your legal duty, and it makes choosing the right course obvious.

What if my workplace has specific risks?

This is where many employers assume they need something complicated, when often they do not. If your workplace has a particular risk, for example staff who work with people who might have seizures, or a setting where children are present, you may need additional or specific training on top of your general first aid cover. The sensible approach is to get your general first aid provision right first, then add any specific training your assessment identifies.

If you are not sure what your particular setting requires, that is exactly the kind of thing worth a quick conversation rather than a guess.

Can we train our staff at our own premises?

Yes, and for many businesses this is the practical choice. Rather than sending people out one at a time to open courses, we can deliver the training on-site at your workplace, which is usually more cost-effective once you are training several staff, and means less disruption to your day. On-site training is quoted per job, because it depends on numbers and location, so the quickest way to get a price is to call and tell us what you need.

So, which course do you need?

For most lower-risk workplaces, Emergency First Aid at Work is enough. For higher-risk or larger workplaces, First Aid at Work is the safer choice. And if you are renewing existing first aiders, Requalification is the efficient route. If you are still unsure, the honest next step is a five-minute chat, we would far rather help you book the right course than the expensive one.
