Are Defibrillators a Legal Requirement in the UK?

Are Defibrillators a Legal Requirement in the UK?

This is one of the most common questions organisations ask when considering a defibrillator.

The short answer is that, in most cases, defibrillators are not currently a legal requirement in the UK. However, that does not mean they are optional from a responsibility or risk management perspective.

Understanding the difference between legal duty and best practice is crucial.

What the Law Says

At present, there is no single piece of UK legislation that explicitly requires all workplaces or buildings to have a defibrillator.

That said, organisations are still bound by wider health and safety and duty of care legislation, including:

• The Health and Safety at Work etc. Act 1974
• The Management of Health and Safety at Work Regulations 1999
• Common law duty of care

These place a responsibility on employers and building owners to identify foreseeable risks and take reasonable steps to reduce harm.

Sudden cardiac arrest is a known and foreseeable risk in workplaces and public environments.

Where Defibrillators Become Expected

Although AEDs are not universally mandated, there are specific sectors and situations where defibrillators are strongly expected or effectively required.

Examples include:

• Schools in England now have compulsory provision for AEDs
• Many sports governing bodies require AEDs at clubs and venues
• Some local authorities mandate defibrillators within new developments
• Insurers increasingly expect AED provision as part of risk management

In these settings, failing to provide a defibrillator can raise questions about preparedness and responsibility.

Guidance vs Legislation

This is where confusion often arises.

While the law may not explicitly state that you must have a defibrillator, UK and international guidance is very clear that early defibrillation saves lives.

Guidance from medical and safety bodies consistently highlights that survival chances decrease rapidly without early defibrillation, AEDs are safe and intuitive to use by untrained individuals, and public access defibrillation improves outcomes.

As a result, many organisations now treat AEDs as essential life-saving equipment, even where the law stops short of mandating them.

Duty of Care and Foreseeable Risk

Duty of care is not about ticking boxes. It is about what is reasonable in the circumstances.

If a cardiac arrest could foreseeably occur in your premises, and this applies to most workplaces and public buildings, it is reasonable to ask:

• Would an AED have been expected here
• Was early intervention realistically possible
• Were opportunities missed to reduce harm

In serious incidents, these questions often arise after the event, not before.

Why Many Organisations Choose to Install an AED Anyway

Organisations increasingly choose to install defibrillators because ambulance response times can vary, AEDs are proven to save lives, staff, visitors, and customers expect higher safety standards, and the cost of an AED is small compared to the potential outcome.

For many, the question becomes not “Is it legally required?” but “Why would we not have one?”

What This Means for You

You may not be legally compelled to install a defibrillator, but you are expected to assess risk and take reasonable steps to protect people.

In many environments, providing an AED is now seen as a proportionate and responsible step. It demonstrates preparation, professionalism, and a genuine commitment to safety.

The Bottom Line

Defibrillators are not universally mandated by law in the UK, but they are increasingly viewed as best practice and part of responsible risk management.

With clear evidence that early defibrillation saves lives, many organisations choose to act before legislation forces their hand.

Because when a cardiac arrest happens, having a defibrillator on site is not about compliance alone.

It is about giving someone the best possible chance of survival.
