Are AEDs a legal requirement in UK workplaces? For most employers, the simple answer is no. There is currently no blanket UK law requiring every workplace to have an Automated External Defibrillator (AED).

However, that does not mean employers should automatically decide that they do not need one.

Employers have legal duties to provide adequate and appropriate first aid arrangements. What is appropriate depends on the workplace, its hazards, workforce, location and other relevant circumstances.

An AED may therefore form an important part of an organisation’s first aid provision even though there is no general law saying every workplace must have one.

This guide explains the difference between legal requirements, workplace risk assessment, HSE guidance and current AED recommendations.

Are AEDs a Legal Requirement for Employers?

There is no specific general legal requirement for UK employers to provide an AED in every workplace.

Resuscitation Council UK confirms this position.

The main legislation governing workplace first aid is the Health and Safety (First-Aid) Regulations 1981.

These require employers to provide adequate and appropriate:

first aid equipment
facilities
personnel

so employees can receive immediate attention if they are injured or become ill at work.

The legislation deliberately does not prescribe identical first aid arrangements for every workplace.

Instead, employers must decide what is adequate and appropriate for their circumstances.

What Does the Health and Safety Executive Require?

The Health and Safety Executive explains the legal duties for workplace first aid.

Employers are required to assess their first aid needs.

That assessment should consider factors such as:

workplace hazards and risks
number of employees
size and layout of the workplace
working patterns
remote or lone workers
distance from emergency medical services
previous incidents
employees with particular needs
members of the public or other non-employees where relevant

The assessment then helps determine the equipment, facilities and personnel the employer should provide.

An AED can be considered as part of this process.

Should an AED Be Considered in a First Aid Needs Assessment?

Yes.

Although AEDs are not a legal requirement for every workplace, considering whether an AED would be appropriate is sensible when reviewing first aid provision.

Resuscitation Council UK has specific guidance on considering an AED as part of a first aid needs assessment.

Factors could include:

number of people using the site
age profile of employees or visitors
nature of the workplace
physical activity taking place
previous cardiac incidents
distance from emergency medical assistance
site size
access for ambulance crews
whether large numbers of members of the public visit
availability of nearby AEDs

The answer will not be the same for every organisation.

A small office and a large sports facility may reach very different conclusions.

What Types of Workplace May Particularly Consider an AED?

There is no definitive list of workplaces that legally require AEDs.

However, an AED may deserve particular consideration in environments such as:

gyms and fitness centres
sports facilities
leisure centres
large factories
warehouses
construction sites
large offices
shopping centres
hospitality venues
schools and colleges
community facilities
transport locations
remote workplaces
sites with large numbers of visitors

The decision should come from the circumstances of the organisation rather than simply its industry name.

For example, the response time for emergency medical services may be an important consideration at a remote workplace.

What About Members of the Public?

The Health and Safety (First-Aid) Regulations primarily concern employees.

HSE states that the Regulations do not place a legal duty on employers to provide first aid specifically for non-employees such as members of the public.

However, HSE strongly recommends that employers include non-employees in their assessment of first aid needs and make appropriate provision for them.

That can be particularly relevant to:

shops
hotels
leisure facilities
visitor attractions
schools
community venues
entertainment venues
sports facilities
large public-facing workplaces

When considering whether an AED is appropriate, think about everyone who may realistically be on the premises.

If an Employer Provides an AED, Does the Law Then Apply?

Yes, and this is an important distinction.

There may not be a general legal requirement to purchase an AED, but once an employer decides to provide one in the workplace, other legal responsibilities become relevant.

HSE’s official First Aid at Work guidance states that where an employer identifies through their needs assessment that they wish to provide an AED, the Provision and Use of Work Equipment Regulations 1998, usually known as PUWER, apply.

The employer should provide appropriate information and written instructions, for example the AED manufacturer’s instructions.

This means an AED should not simply be purchased, mounted on a wall and forgotten.

What Does PUWER Mean for a Workplace AED?

PUWER covers work equipment and includes requirements relating to areas such as suitability, safe use and maintenance.

For a workplace AED, practical responsibilities include ensuring that it remains suitable and ready for use.

That links directly to:

following manufacturer instructions
monitoring the AED’s status
replacing expired pads
monitoring battery condition
dealing with faults
keeping the equipment accessible
providing appropriate information and instructions

Our guide to AED maintenance and keeping a defibrillator emergency ready explains these responsibilities in more detail.

Does the Law Require AED Training?

This is another area where the answer needs care.

A person does not need an AED certificate before they can use a defibrillator during an emergency.

Modern AEDs are designed so members of the public can use them.

The device analyses the casualty’s heart rhythm and will only advise or deliver a shock when appropriate.

Resuscitation Council UK specifically advises that AED use should not be restricted to trained personnel.

If somebody is in cardiac arrest, defibrillation should not be delayed because the person available has not completed formal AED training.

You can read our practical guide explaining how to use an AED during a cardiac arrest.

Why Train Staff If Anyone Can Use an AED?

Because training improves confidence and preparedness.

There is a significant difference between being physically capable of following an AED’s instructions and having practised responding to a cardiac arrest.

Training allows people to practise:

recognising cardiac arrest
calling 999
starting CPR
sending someone for an AED
switching the AED on
attaching pads
following voice and visual prompts
delivering a shock when instructed
continuing CPR
working effectively with other rescuers

HSE notes that fuller training is likely to make users more confident and that AED use forms part of the syllabus for both First Aid at Work and Emergency First Aid at Work courses.

The key point is:

Training is strongly beneficial, but an untrained person should still use an available AED during a cardiac arrest.

Are AEDs Covered in Workplace First Aid Courses?

Yes.

Practical CPR and AED use form part of current workplace first aid training.

At First Aid and Safety Training, learners practise using training defibrillators during relevant courses rather than simply discussing them theoretically.

Our Emergency First Aid at Work course includes CPR and AED use.

Our more comprehensive First Aid at Work course also includes practical resuscitation skills.

This helps first aiders become familiar with the equipment before facing a genuine emergency.

Can Someone Be Sued for Using an AED?

Fear of legal consequences can make people hesitant during an emergency.

There are no statutory legal provisions in the UK specifically governing the act of performing resuscitation or using a defibrillator.

Resuscitation Council UK provides detailed guidance in CPR, AEDs and the law covering the responsibilities of rescuers and organisations.

The practical message for members of the public is straightforward:

Do not allow fear of using an AED to delay attempting to save somebody in cardiac arrest.

AEDs are designed to guide the rescuer through the process and analyse whether a shock is appropriate.

Could an Organisation Be Liable for Not Having an AED?

This question is more complicated than simply asking are AEDs a legal requirement?

There is no blanket statutory requirement saying every organisation must provide one.

However, organisations have wider duties to manage foreseeable risks.

Resuscitation Council UK’s legal guidance discusses the possibility of common law considerations where an organisation does not provide an AED, particularly where circumstances suggest a higher risk or where AED provision has become established practice.

This does not mean every business without an AED is automatically negligent.

It means organisations should make a considered decision rather than assume that the absence of a specific statutory AED requirement ends the discussion.

A documented assessment provides a much stronger basis for deciding what is appropriate.

What Does BS 8599-1:2019+A1:2026 Change?

There has been an important development in 2026.

The British Standard BS 8599-1:2019+A1:2026 now covers:

Workplace first aid kits, contents of first aid kits and provision of Automated External Defibrillators in the workplace.

This reflects the growing importance of AED provision within workplace emergency preparedness.

However, a British Standard is not the same thing as legislation.

The new standard does not suddenly create a blanket law requiring every employer in the UK to install an AED.

Instead, it provides a recognised standard that organisations can use when considering good practice.

We have covered the change separately in our guide to BS 8599-1:2019+A1:2026 and workplace first aid provision.

Are AEDs a Legal Requirement in UK Workplaces Do you need one.

Law, Guidance and Standards Are Not the Same Thing

This distinction is important.

Legislation

Legislation creates legal duties.

For workplace first aid, the principal regulations are the Health and Safety (First-Aid) Regulations 1981.

HSE Guidance

HSE guidance helps employers understand how to comply with their legal responsibilities.

British Standards

Standards such as BS 8599-1:2019+A1:2026 provide recognised specifications and good-practice frameworks.

They are not automatically legislation.

Resuscitation Guidance

Resuscitation Council UK provides evidence-based guidance on CPR, AEDs and resuscitation practice.

Understanding these differences prevents recommendations from being incorrectly presented as legal requirements.

Are AEDs a Legal Requirement Under the New 2026 Standard?

No.

This is likely to become an increasingly common question following the publication of the updated British Standard.

BS 8599-1:2019+A1:2026 does not itself make AEDs a legal requirement in every workplace.

Employers should still consider their own first aid needs and the circumstances of their workplace.

The standard is important because AED provision now sits explicitly within the scope of the recognised workplace first aid standard, but that should not be confused with a new Act of Parliament or statutory regulation requiring every employer to purchase one.

What If Your Workplace Decides to Install an AED?

Once the decision has been made, think beyond purchasing the machine.

A complete workplace AED arrangement should consider:

Location
Can the AED be reached quickly?
Visibility
Can people find it during an emergency?
Accessibility
Can it be accessed whenever people are on site?
Signage
Are people clearly directed towards it?
Maintenance
Are pads, batteries and status indicators monitored?
Responsibility
Is someone responsible for checking the AED?
Training
Have staff had an opportunity to practise CPR and AED use?
Emergency procedures
Do staff know to call 999, start CPR and retrieve the AED?
Registration
Where appropriate, is the AED registered with The Circuit?
Review
Are arrangements reconsidered when the workplace changes?

Our AED placement guidelines cover location, signage, accessibility and registration in more detail.

Should Workplace AEDs Be Registered with The Circuit?

Where an AED is available for public access, it should be registered with The Circuit, the national defibrillator network.

The Circuit allows ambulance services to identify registered defibrillators during 999 calls.

The record includes information about the AED’s:

location
accessibility
rescue-ready status
pad expiry
availability

If an organisation chooses to make its AED available to the wider community, registration is an important part of making that equipment genuinely useful.

Does Having an AED Replace CPR?

No.

An AED forms part of the response to cardiac arrest. It does not replace CPR.

If somebody is unresponsive and not breathing normally, the emergency response includes:

calling 999
starting CPR
obtaining an AED
using the AED as soon as possible
following its instructions
continuing CPR as directed

Early CPR helps maintain blood flow while defibrillation may correct certain shockable heart rhythms.

The two interventions work together.

Do You Need an AED in Your Workplace?

There is no universal answer.

Ask questions such as:

How many people use the premises?
Are members of the public regularly present?
Is strenuous physical activity carried out?
How large is the site?
How quickly could an ambulance realistically reach the casualty?
Is the workplace remote?
Are there existing nearby AEDs?
Can those AEDs actually be accessed during your operating hours?
Have previous medical emergencies occurred?
Does your industry or environment create additional considerations?
What does your first aid needs assessment indicate?

The decision should be proportionate and documented.

Are AEDs a Legal Requirement? The Key Points

If you are trying to establish are AEDs a legal requirement, remember these main points:

There is no blanket UK law requiring every workplace to have an AED.
Employers must provide adequate and appropriate first aid arrangements.
A first aid needs assessment should determine appropriate provision.
An AED can form part of that provision.
Once an employer provides an AED, PUWER becomes relevant.
Manufacturer instructions and appropriate information should be provided.
Anyone can use an AED in an emergency.
Formal certification is not required before someone can attempt to use one.
Training can significantly improve confidence.
AEDs should be properly located, checked and maintained.
BS 8599-1:2019+A1:2026 is a British Standard, not a new blanket legal requirement.
Organisations should review AED provision as part of wider emergency preparedness.

Build AED Provision into Your First Aid Arrangements

Whether an AED is appropriate should not be considered in isolation.

It forms part of a wider system that includes first aid needs assessment, trained personnel, emergency procedures, equipment, CPR skills and ongoing checks.

First Aid and Safety Training provides regulated workplace first aid qualifications and practical CPR and AED training for organisations across the North East.
