AED Workplace Requirements for UK Employers

A colleague collapses in a reception area. Someone calls 999, another begins CPR, but the nearest defibrillator is locked away, its pads are out of date, and nobody knows who has the key. AED workplace requirements are not simply about buying a device. They are about ensuring it can make a meaningful difference during the few critical minutes of a cardiac arrest.

For UK employers, an automated external defibrillator (AED) can be a valuable addition to workplace first aid provision. Whether one is required depends on the findings of your first aid needs assessment, the nature of your workplace, and the people who use it. A considered approach protects staff, visitors and the organisation itself.

Are AEDs legally required in UK workplaces?

There is no blanket UK law stating that every workplace must have an AED. The Health and Safety (First-Aid) Regulations 1981 require employers to provide adequate and appropriate equipment, facilities and personnel so employees can receive immediate attention if they are injured or taken ill at work.

What counts as adequate will differ between organisations. A small, low-risk office with a handful of employees may reach a different conclusion from a large school, warehouse, care setting, leisure venue or factory. Employers should make this decision through a documented first aid needs assessment rather than treating a defibrillator as a universal compliance purchase.

That said, the absence of a specific legal duty to install an AED does not mean it should be dismissed. Cardiac arrest can happen in any setting, to employees, contractors, customers or members of the public. AEDs are designed to analyse a person’s heart rhythm and, where appropriate, advise or deliver a shock. Used alongside early CPR and a 999 call, they can give someone a better chance of survival.

What an AED workplace requirements assessment should cover

A first aid needs assessment should look beyond the number of employees on payroll. It should reflect how your organisation actually operates, including the people on site at different times and the risks they may face.

Consider four practical areas:

• The size, layout and accessibility of the premises, including separate floors, remote buildings, large outdoor areas and security-controlled access.

• The nature of work, particularly physical activity, manual handling, exposure to heat, lone working, shifts or locations where emergency services may take longer to reach.

• The workforce and visitors, including the number of people on site, their age profile, known health considerations where relevant, and whether the premises are open to the public.

• Existing emergency arrangements, such as trained first aiders, CPR capability, emergency contacts, nearby public-access AEDs and how quickly someone could retrieve one.

A busy community venue may need an AED even if its staff undertake relatively low-risk work because of the number and variety of visitors. Conversely, a very small office located next to an accessible, registered public AED may decide that investment in additional first aid training and clear emergency procedures is the more proportionate immediate step. The point is not to reach a predetermined answer. It is to make a reasoned decision that can be reviewed.

Choosing the right location and level of access

An AED only helps if it can be collected quickly. Positioning it in a manager’s office, a locked cupboard or a room that is unavailable outside normal hours can undermine the purpose of having one.

Choose a visible, clearly signed location that is easy to reach from the areas where people work or visit. In larger premises, consider travel time rather than assuming one centrally placed device covers every corner. If your building has multiple floors, outbuildings or high footfall areas, a second AED may be sensible.

Access arrangements need equal attention. If the AED is available only during working hours, make that clear in your emergency planning. For sites with evening staff, contractors or public activity, an external heated cabinet may be appropriate, subject to security, weather protection and the manufacturer’s instructions. An outdoor cabinet can also extend the benefit to the surrounding community, but it brings additional responsibilities for checks and upkeep.

Clear signage matters. Staff should know where the AED is before an emergency occurs, and visitors should be able to identify it without needing to ask. Include the location in induction information, first aid notices and emergency plans.

Training staff to act without delay

AEDs are designed to be used by lay responders. Most provide clear voice and visual prompts, and a person should not delay using one because no formally trained responder is immediately available. The emergency services call handler can also provide instruction over the phone.

However, practical AED and basic life support training gives people confidence when the pressure is real. Staff learn how to recognise a suspected cardiac arrest, call 999, start effective CPR, retrieve and apply the AED, and work together until the ambulance service arrives. They also have an opportunity to practise managing the realities of an emergency: moving furniture, directing colleagues, protecting privacy and handing over information.

Not every member of staff needs to hold a first aid certificate, but your arrangements should not rely on one named person who may be on holiday, unwell or working elsewhere. Train enough people to cover shifts, departments and locations, then encourage all staff to understand the basic emergency process.

For many organisations, AED/basic life support training sits well alongside Emergency First Aid at Work or First Aid at Work provision. It can also be valuable in schools, care services, charities and public-facing organisations where visitors form a significant part of the risk profile.

Maintenance is part of compliance

An AED is not a fit-and-forget piece of equipment. Assign a named person, with a deputy, to carry out and record regular checks. The device should show that it is ready for use, and the inspection should confirm that the cabinet, signage and associated equipment remain in good condition.

Pads and batteries have expiry dates, even when they have never been used. If either item expires, the AED may not be ready in an emergency. Keep a simple register showing the device model and serial number, pad and battery expiry dates, the date of each check, and any action taken. Your checks should also confirm that scissors, gloves, a face shield or resuscitation mask, and other supplied items are present where applicable.

After an AED is used, replace the pads and any other single-use items promptly. The device may also hold event data that emergency responders or clinical teams need. Follow the manufacturer’s instructions, arrange servicing where necessary and make sure the AED is returned to ready status before treating the incident as closed.

Registering the AED and planning the response

Where possible, register the AED with the local ambulance service or recognised defibrillator network so call handlers can direct 999 callers to it. Registration is especially useful where the device is accessible to the public, but it is good practice for workplace AEDs too. Keep registration details current if the device is moved, replaced or taken out of service.

Your emergency procedure should be short enough for people to follow. It should establish who calls 999, who brings the AED, who starts CPR, who meets the ambulance crew, and how the building is accessed. In a small team, one person may carry out several of these actions, so the procedure must be realistic rather than overly complicated.

Run occasional, respectful drills. A five-minute walk-through can reveal that a security door blocks access, a reception team does not know the exact address to give the ambulance service, or the AED cabinet key is not where it should be. These are manageable problems when found during planning, not during a medical emergency.

Reviewing your provision over time

Review your first aid needs assessment at least periodically and whenever circumstances change. Growth in staff numbers, a move to new premises, different shift patterns, a rise in public footfall, or changes to work activities may all alter what is adequate.

It is also worth reviewing after a serious incident or near miss. The purpose is not to assign blame. It is to understand whether staff could access equipment, communicate effectively and provide the best available support while waiting for emergency services.

A defibrillator is most effective when it is one part of a prepared workplace: visible equipment, trained and willing responders, confident CPR, clear emergency roles and routine maintenance. MI Team Training can support organisations with practical AED and basic life support training delivered on site, helping teams practise the actions that matter when every second counts.

The best time to test an AED plan is when nobody needs it. Give your team the knowledge, equipment and permission to act quickly, then keep those arrangements ready for the day they may be needed.
