Sudden cardiac arrest strikes over 30,000 people annually in the UK outside of hospitals, according to the British Heart Foundation (BHF). Automated External Defibrillators (AEDs) play a crucial role in emergency response, with survival rates jumping to 50-70% when defibrillation occurs within 3-5 minutes. Without immediate defibrillation, survival chances decrease by 10% per minute, highlighting the importance of quick access to an AED. Whether for workplaces or public spaces, selecting the right AED ensures readiness in critical situations and can be the difference between life and death.

An external defibrillator is a medical device designed to deliver an electric shock to the heart during sudden cardiac arrest. AEDs (Automated External Defibrillators) are the most common type, designed for public use with simple voice and visual prompts to guide rescuers. Unlike manual defibrillators used by medical professionals, AEDs analyse the heart rhythm and only deliver a shock if necessary, ensuring safe operation by non-medical users.

When purchasing an AED, several factors come into play:

• Type of Defibrillator – AEDs are the best choice for non-medical users due to their simplicity and guided prompts. Fully automatic AEDs deliver a shock without user intervention, whereas semi-automatic AEDs require the rescuer to press a button to administer the shock.
• Regulatory Compliance – Ensure the device has UKCA or CE marking for safety and reliability, as these approvals confirm the AED meets the required safety standards.
• Ease of Use – Look for models with clear voice and visual instructions, as well as CPR feedback features, to ensure ease of operation for users with minimal training.
• Battery Life & Maintenance – Opt for long-lasting batteries and minimal upkeep to reduce ongoing costs. Some AEDs have self-check functions that alert users when maintenance is required.
• Cost & Value – Balance affordability with quality and essential features, considering both the upfront cost and the cost of replacement pads and batteries over time.
• Size & Portability – Compact AEDs are ideal for mobile use, such as at events, while larger, more robust models may be better suited for permanent installations in public spaces.
• Warranty & Support – Choose suppliers that offer strong after-sales support, training resources, and warranties to ensure your AED remains in working condition.

The number of AEDs required depends on the environment. UK guidelines suggest:

• Small Workplaces (under 50 employees) – One centrally located AED is generally sufficient, as long as it is accessible within a 3-5 minute window.
• Larger Workplaces (50-100 employees per unit) – Place AEDs within a 3-5 minute reach, ensuring coverage across all key areas. A large factory or warehouse may need 5-10 units depending on its layout.
• Public Spaces (shopping centres, transport hubs, stadiums, schools) – Multiple AEDs are advised for high footfall areas, with clear signage to ensure easy location in an emergency.
• High-Risk Areas (gyms, construction sites, care homes, medical facilities) – Additional units may be needed due to increased risk, ensuring AEDs are accessible near high-risk activities such as heavy lifting, strenuous exercise, or medical treatment areas.
• Remote Locations & Outdoor Settings – If your environment is remote, such as a countryside venue, outdoor event space, or offshore site, consider an AED with a rugged design and extended battery life to withstand harsher conditions.

Though not legally required, the Health and Safety Executive (HSE) encourages workplace AED installations as a key safety measure. The Resuscitation Council UK recommends AEDs in workplaces and public locations where there is a risk of cardiac arrest.

The cost of an AED varies based on its features and specifications:

• Basic Models – Entry-level AEDs with essential features range from £800-£1,200.
• Advanced AEDs – Devices with CPR feedback, Wi-Fi monitoring, and paediatric modes typically cost between £1,200-£2,000.
• Professional-Grade AEDs – AEDs designed for medical settings with ECG displays and manual override can exceed £2,500.

In addition to the initial purchase price, consider the long-term costs of replacement pads, batteries, and servicing.

Selecting the right AED depends on the setting. Here are top recommendations from Qualsafe:
