You finish your Emergency First Aid at Work (EFAW) course feeling confident. You know where to put your hands, how fast to push and what the defibrillator does. Then life carries on. Months pass. You do not use any of it. So how much do you still remember a year later? And what about after three years, when your certificate is due to expire?
This is called skill fade, and it is one of the main reasons first aid training has refreshers and renewals. In this guide, we explain in plain English what research suggests about how quickly first aid skills fade, which skills fade first, what helps slow the fade and how to keep your skills fresh at very little cost. If you want to see a real course page as you read, here is the Emergency First Aid at Work course in London.
The Short Answer
Research on CPR training suggests that the quality of skills can begin to drop within about three to six months after training if they are not practised. Hands on skills such as chest compressions tend to fade faster than basic knowledge, while skills such as using an AED seem to hold up better. The exact speed varies from person to person and from study to study.
The practical lesson is simple. A three year certificate does not mean three years of sharp skills. Regular short practice, and a yearly refresher, keep you ready.
What Is Skill Fade?
Skill fade, sometimes called skill decay, is the gradual loss of a skill when you do not use it. It happens with many skills, such as driving a manual car after years of automatics, speaking a language you have not practised or playing an instrument you put away.
First aid skills are especially prone to it for two reasons.
- You rarely use them. Most people never perform CPR on a real person, so there is little natural practice.
- They are physical. Chest compressions, the recovery position and bandaging depend on how your body moves, and physical skills fade if you do not repeat them.
What the Research Suggests
There is a lot of research on how quickly CPR skills fade, and while the details vary, a pattern appears.
- Within three to six months. Reviews of studies note that CPR specific skills and knowledge deteriorate within three to six months of initial training. One university study found that skills deteriorated within three months, then levelled off between three and six months before declining further.
- Compression quality is often the first to slip. A review of school based CPR training found a marked reduction in chest compression quality within six to eight months after training. Depth, rate and hand position are common weak points.
- Some skills hold better. In a large trial of trained lay volunteers, CPR skills deteriorated slightly, but about 80 percent remained competent up to one year, and AED skills did not significantly deteriorate, with around 90 percent remaining competent. That trial included a refresher at about six months, so it shows what is possible when training is repeated.
- Instructor feedback helps. The same university study found that instructor led training with feedback gave the greatest improvement for people who were not health professionals, though video training was almost as good.
- Short refreshers can help. A small trial found that a two minute video refresher at three months improved six month retention of key CPR skills in college students, including recognising cardiac arrest, calling for help and chest compression performance.
- Results are not always consistent. Another trial found that short self learning refreshers every three or six months did not improve compression depth a year later for the group as a whole, though they may help people with poor skills. So more practice is generally helpful, but the best method is still debated.
These studies mostly involve laypeople, students and health workers, not specifically EFAW learners, but the lessons apply to anyone who learns CPR and then does not use it.
A Rough Timeline of Skill Fade
Because results vary, think of this as a general picture rather than a precise schedule.
Straight after the course
- Your skills and confidence are at their peak.
One month
- Most people still remember the steps well, though small details may blur.
Three months
- Hands on quality can start to fall in some people, especially chest compression depth, rate and hand position.
Six months
- Many studies show a noticeable decline in compression quality for those who have not practised. Confidence may also drop.
Twelve months
- Without practice, many people have lost some precision. With a refresher, most can recover quickly. This is where HSE’s yearly refresher recommendation fits.
Two years
- The order of steps may still be remembered, but the physical details need real practice.
Three years
- The certificate expires. Without practice, you may need to rebuild skills, which is why renewal means retaking the full course.
This timeline is a guide only. If you use your skills often, or practise regularly, your fade will be slower.
Which Skills Fade First?
Not all skills fade at the same speed. Based on what studies tend to find:
Often fade faster
- Chest compression depth and rate. Getting the right force and rhythm is hard to maintain without practice.
- Hand position. Small errors creep in.
- Rescue breaths. Technique and timing can slip.
- The exact order of steps under pressure. You may remember the idea but hesitate on the sequence.
- Choking techniques. Back blows and abdominal thrusts are used rarely and are easy to forget.
Often hold better
- Recognising that something is wrong. The basic idea of checking for response and breathing sticks.
- Calling 999. Most people remember to call for help.
- Using an AED. The machine gives spoken instructions, and studies suggest that AED skills hold up well.
- General knowledge. Understanding why you do things often lasts longer than physical technique.
This is why practical refreshers focus on hands on skills.
What Makes Fade Faster or Slower?
Several things affect how quickly you lose skills.
Things that slow the fade
- High quality initial training. Plenty of hands on practice, good feedback and a clear method.
- Feedback devices. Manikins that show depth and rate help you learn the right feel.
- Repetition. Practising the same skill several times in the course and afterwards.
- Regular refreshers. Short sessions every few months to a year.
- Real use. If your job involves first aid, you practise more.
- Confidence and motivation. People who feel it matters tend to practise more.
- Simple, clear steps. A method that is easy to recall under stress.
Things that speed it up
- Long gaps with no practice.
- A short or rushed course.
- Crowded classes with few manikins.
- No feedback.
- High stress or distraction.
- No reminders or follow up.
That is why choosing a good course matters. A course with plenty of hands on practice and a qualified trainer gives you a stronger starting point.
Why It Matters in Real Emergencies
In a real emergency, quality matters. More than 30,000 people have an out of hospital cardiac arrest in the UK each year, according to the British Heart Foundation, and fewer than one in ten survive. Every minute without CPR and defibrillation reduces the chance of survival by up to 10 percent. Good compressions, started quickly, can keep blood and oxygen moving until help arrives. If your compressions are too shallow or too slow because your skills have faded, they are less effective. And if you hesitate because you have lost confidence, you may lose precious minutes.
What the evidence also shows is that doing something is better than doing nothing. Any previous training is generally better than none, and even imperfect CPR can help. The aim of practice is to make it as good as possible.
What HSE Recommends
HSE strongly recommends that first aiders take refresher training each year, over about half a day, during any three year certification period. It is not mandatory, but HSE says it helps first aiders maintain their basic skills and keep up to date with any changes to first aid procedures. A refresher does not renew your certificate, so you still need to retake the full one day course before your three years end.
The Health and Safety (First Aid) Regulations 1981 require employers to provide adequate and appropriate first aid for their employees. HSE stopped approving first aid training providers in 2013, so employers rely on regulated qualifications and good practice to keep first aiders competent. For more detail, see our guide on annual first aid refresher training.
A Simple Plan to Slow Skill Fade
You do not need to spend hours. A little practice, often, goes a long way. Here is a simple routine.
Within a week of the course
- Review your notes while the course is fresh.
- Write the key steps in your own words.
- Find your workplace first aid kit and AED.
Every month: five minutes
- Walk through the CPR steps in your head, in order.
- Say the steps out loud: check danger, check response, call for help, check breathing, start compressions, send for the AED.
- Picture where your workplace first aid kit and AED are.
Every three months: ten to fifteen minutes
- Watch a short refresher video from a trusted source.
- Practise the recovery position with a friend or family member.
- Practise hand position and compression rhythm on a firm cushion, not on a real person. Never practise chest compressions on someone who is breathing normally.
- Review the steps for choking.
Every six months: a quick self test
- Ask yourself the questions from a short self test. For example, where do your hands go, how fast should compressions be and what does the AED do first?
- If you struggle, book a practical session.
Every year: a refresher
- Take a half day refresher with a trainer, as HSE recommends.
Every three years: renewal
- Retake the full course before your certificate expires.
This pattern uses frequent, short practice, which research suggests is a good way to keep skills in place, supported by occasional hands on sessions with feedback.
What About Videos and Apps?
Videos and apps are useful, especially between courses. Studies suggest that brief video refreshers can help skill retention, and that video training can be almost as good as instructor led training for some measures. But they work best alongside practical sessions. A video cannot see your hands or tell you that your compressions are too shallow. Instructor led training with feedback tends to be slightly better for depth, hand placement and minimising interruptions.
Charities such as the British Heart Foundation offer free online tools that teach CPR and defibrillator use in minutes. These are helpful for awareness and for a quick memory jog, but they do not replace a practical refresher with a qualified trainer for workplace first aiders.
Tips for Employers
If you manage first aiders, build practice into your routine.
- Schedule annual refreshers. Many providers offer half day sessions, and training at your premises saves travel time.
- Add short drills. Five minute practice sessions at team meetings keep skills alive.
- Share reminders. A quarterly email with a link to a short refresher video helps.
- Check the AED. Make sure first aiders know where it is and how it works.
- Track dates. Record course dates, refresher dates and expiry dates.
- Stagger renewals. So not everyone expires at once.
As a starting point for low hazard workplaces, HSE suggests at least one appointed person for fewer than 25 employees, at least one first aider trained in Emergency First Aid at Work for 25 to 50 employees, and at least one first aider trained in First Aid at Work for every 100 employees above that, or part of 100. Higher hazard workplaces need more. A first aid needs assessment gives the best answer.
Choosing a Course That Slows Fade
A good course gives you a stronger start. Look for:
- A regulated Level 3 Award in Emergency First Aid at Work (RQF) from a recognised awarding organisation.
- At least six hours of training time, not counting breaks.
- Plenty of hands on practice with manikins and a training AED.
- A qualified trainer who gives feedback.
- Small classes. Many awarding organisations set a maximum of around 12 learners per trainer.
- A clear certificate and, ideally, an offer of refreshers.
Be cautious of online only offers and any claim that a course is HSE approved. In London in 2026, public prices for a one day course commonly range from about £65 to £150 per person. One provider page, linked above, lists £89 per person for classroom training and £75 per person for groups of five or more, at the time of writing in October 2026. Prices change, so always confirm. You can review the Emergency First Aid at Work training page to see how one provider presents its course, price and booking options.
Why London First Aiders Should Keep Practising
London workplaces are busy, tightly packed and often spread across several floors. Roads and public transport can be crowded, so ambulances may take time to reach a patient, and the people on site are often the first help available. There is also a very large number of providers and dates in London, and many deliver training at your workplace, so a refresher is rarely hard to arrange.
Final Thoughts
So, how quickly do first aid skills fade without practice? Research suggests that hands on quality, especially chest compressions, can begin to decline within about three to six months, while basic knowledge and AED skills tend to hold up better. Exact speeds vary, but the pattern is clear: a certificate that lasts three years does not guarantee three years of sharp skills.
The fix is easy and cheap: short, regular practice, a yearly refresher and renewal before your certificate expires. When you are ready, take a look at the Emergency First Aid at Work course in London and choose a date that suits you.
Frequently Asked Questions
1. How quickly do first aid skills fade?
Research suggests that the quality of hands on skills such as chest compressions can start to decline within about three to six months without practice. Basic knowledge and AED skills tend to hold up better. The exact speed varies from person to person.
2. Which first aid skills are forgotten first?
Hands on skills such as chest compression depth, rate and hand position, rescue breaths and choking techniques tend to fade faster. Recognising an emergency, calling for help and using an AED tend to hold up better.
3. Why do first aid certificates last three years if skills fade sooner?
Three years is the standard period before a full reassessment. Because skills can fade sooner, HSE strongly recommends a short refresher each year, although it is not a legal requirement, and a refresher does not extend the certificate.
4. How often should I practise my first aid skills?
A little often works well. Walk through the steps in your head monthly, practise the recovery position and review videos every few months, and take a half day refresher each year. Retake the full course before your three year certificate expires.
5. Do videos help prevent skill fade?
Yes, as a supplement. Studies suggest that brief video refreshers can help retention, but they work best alongside practical sessions with a trainer who can give feedback on technique.
6. Can I practise CPR at home?
You can practise hand position and rhythm on a firm cushion, and walk through the steps. Never practise chest compressions on a real person who is breathing normally. A practical session with a manikin and a trainer is the best way to check your technique.
7. Do AED skills fade as quickly as CPR skills?
Research suggests that AED skills tend to hold up better than chest compression skills, partly because the machine gives spoken instructions. It is still wise to practise with a training AED during refreshers.
8. Is imperfect CPR better than no CPR?
Yes. Any previous training is generally better than none, and even imperfect CPR can help. The aim of practice and refreshers is to make your CPR as effective as possible.
9. How can employers help first aiders keep their skills?
Schedule annual refreshers, add short practice drills at team meetings, share reminders and videos, check that first aiders know where the AED is, track expiry dates and stagger renewals.
10. Where can I take Emergency First Aid at Work training in London?
You can book through a training provider that offers the regulated qualification, either as a public course or as training at your workplace. Check the practical content, the class size, the awarding organisation and the total price before you book.
