When it comes to life-saving equipment, few devices are more critical than the defibrillator. Whether you manage a workplace, school, sports club or simply want to be prepared at home, choosing the right defibrillator can feel overwhelming. With nearly 30 years of experience in the UK medical device industry, we’ve written this practical guide to help you make an informed decision.
Types of Defibrillators in the UK
There are several types of defibrillators, each suited to different environments and users. Understanding the differences will help you choose the right model for your needs.
1. Automated External Defibrillator (AED)
AEDs are designed for use by members of the public and non-medical staff. They provide clear voice and visual instructions to guide the user through the resuscitation process. These are the most common type of defibrillator found in UK workplaces, leisure centres, schools, transport hubs and public spaces.
Key Benefits:
- Easy to use
- Safe and automated
- Portable
- No prior training required (although training or familiarisation is strongly recommended to build confidence and understanding)
Best For:
Offices, schools, sports clubs, shops, community centres, and home use.
Features to Consider:
- Fully-Automatic vs Semi-Automatic: Fully-automatic units deliver the shock without user input, while semi-automatic models prompt the user to press a shock button.
- CPR Feedback: Real-time CPR feedback can significantly improve the quality of chest compressions, which has a direct link to improved survival outcomes. High-quality CPR is as important as the shock itself.
- Durability: Go beyond IP ratings – look for drop test standards, weather resistance, and rugged housing. Consider the number and type of internal self-checks the unit performs daily or weekly.
- Paediatric Mode or Pads: Essential for environments where children may be present.
- Display Features: Models with LCD screens are beneficial in noisy environments or for users with hearing impairments.
- Component Quality: Better components often mean higher sensitivity in rhythm analysis and improved reliability. Some units can detect a shockable rhythm more accurately or analyse the heart rhythm during CPR, reducing pause times and increasing effectiveness.
Not all defibrillators are created equal. Cheaper units may lack key features or use outdated technology. It’s worth considering total cost of ownership — some higher-end devices offer better long-term value, with extended warranties, superior self-check routines, and lower consumable costs over time.
2. Manual External Defibrillator
These are used by trained healthcare professionals and require the user to interpret the ECG and control the shock manually.
Best For: Ambulances, hospitals, and clinical environments.
3. Manual Internal Defibrillator
Used during surgery to deliver shocks directly to the heart via internal paddles.
Best For: Surgical teams and cardiac theatres.
4. Wearable Cardioverter Defibrillator (WCD)
A temporary, non-invasive solution for patients at risk of sudden cardiac arrest who aren’t yet candidates for implantable devices.
Best For: Medically supervised patients.
5. Implantable Cardioverter Defibrillator (ICD)
Surgically implanted to monitor and correct life-threatening arrhythmias.
Best For: High-risk cardiac patients under specialist care.
Key Considerations When Buying a Defibrillator
1. Who Will Be Using It?
For public or workplace settings, an AED is almost always the best choice. Designed for ease of use, they empower bystanders to act quickly in emergencies. Training is not a legal requirement, but familiarity sessions and staff training are strongly advised.
2. Where Will It Be Located?
-
Indoor Use: Offices, gyms, schools — a standard AED will usually suffice.
-
Outdoor or Harsh Environments: Look for units with high IP ratings, drop resistance, and robust cases.
-
Multiple Sites: Large premises may need more than one AED. Aim for response time within 1–2 minutes.
3. What Features Do You Need?
-
Clear Instructions: Visual and voice guidance is essential.
-
Battery Life: Understand the difference between shelf life, operational standby time, and the manufacturer’s warranty on energy delivery.
-
Maintenance Alerts: Be cautious — some units perform hundreds of daily checks while others only do minimal weekly routines. Battery capacity may indicate how much internal checking is actually being done.
-
Connectivity: Some AEDs offer Wi-Fi or Bluetooth to report readiness remotely.
-
Warranty Clarity: Some warranties cover only manufacturing defects, while others include battery capacity and pad longevity. Always read the small print.
4. Budget and Running Costs
AEDs in the UK typically range from £850 to £2,000. Consider: - Initial cost of the unit - Replacement pads and batteries (e.g. every 2–5 years depending on model) - Storage cabinets or carry cases - Training costs - Leasing options for large rollouts
Note: Some manufacturers use inflated battery life figures by combining shelf life and operational standby time — be sure to ask for separate figures.
5. Legal and Safety Considerations in the UK
-
You do not need a license or training to use an AED.
-
Under the Social Action, Responsibility and Heroism (SARAH) Act, the risk of legal liability for using an AED is extremely low, especially if acting to help someone in an emergency.
-
Organisations may be more exposed to risk by not having an AED on site than by having one.
-
Register your AED with your local ambulance service (via The Circuit).
-
Ensure signage is visible and access is unrestricted.
Ongoing Management: More Than Just Buying the Device
For organisations, buying a defibrillator is only the first step. Ensuring it’s always ready to use requires ongoing management:
-
Right unit, right number, right location: We offer professional site surveys to ensure optimal coverage and placement.
-
Governance and daily readiness: Our systems monitor device status, perform logging, and alert users to issues.
-
Annual servicing: Compliant with PUWER regulations and supports long-term reliability.
-
Replacement consumables: Pads and batteries are tracked and replaced as needed.
-
Staff training: Delivered by our partners, including the East of England Ambulance Service, ensuring consistency and clinical quality.
-
Post-incident planning: Restocking, recommissioning, and supporting staff involved in an emergency, especially if the casualty is a colleague.
-
Leasing and funding support: We offer leasing options for large deployments or budget-constrained organisations.
-
Manufacturer support: We supply high-quality devices from manufacturers with in-country service and support — not just low-cost imports with limited UK representation.
Whether you’re just starting out or already managing a fleet of devices, we can help ensure your defibrillator programme is effective, compliant, and fully supported.
Expert Insight: Don’t Let Complexity Delay Action
With decades in the defibrillator sector, we’ve seen time and again how having an AED on site can save lives. But not all defibrillators are created equal. Choosing a well-supported, clinically proven model from a trusted provider ensures you’re not just ticking a box — you’re protecting lives.
If you’re unsure where to start, we’re here to help you make the right choice, and support you every step of the way.
Final Thoughts: Be Prepared, Save Lives
Sudden cardiac arrest can happen anywhere, at any time. Choosing the right defibrillator — and ensuring it’s visible, maintained, and supported by a basic action plan — can make all the difference.
