The UK has reached a significant milestone with the registration of its 100,000th public access defibrillator (PAD) on the national circuit — the network of AEDs linked to ambulance service dispatch systems that can be directed to by 999 call handlers. However, a new analysis by the British Heart Foundation has highlighted significant disparities in coverage across the country.
Geographic Disparities
The analysis found that while urban areas in England generally have good AED coverage — with devices typically within 500 metres of most locations — rural areas and some urban deprived communities have significantly fewer devices per capita. In some rural areas, the nearest registered AED may be more than 2 kilometres away, making it effectively inaccessible within the critical 3–5 minute window for defibrillation.
The Importance of AED Registration
Many AEDs are not registered on the national circuit, meaning that 999 call handlers cannot direct bystanders to them. The British Heart Foundation estimates that there may be a further 50,000–70,000 unregistered AEDs in the UK, primarily in workplaces, schools, and sports facilities. Registration is free and takes only a few minutes at www.defibfinder.uk.
"Every AED that isn't registered is a potentially life-saving device that might never be used in an emergency. Registration costs nothing and could save a life." — British Heart Foundation
Employer Obligations
While there is currently no legal requirement for most employers to provide an AED, the HSE guidance on first aid needs assessment encourages employers to consider whether an AED would be appropriate given their workplace risk profile. Employers in higher-risk settings, or those with large numbers of employees or members of the public, are particularly encouraged to provide AEDs and ensure staff are trained in their use.

Modern AEDs are designed to be used by untrained bystanders — they provide clear voice instructions and will not deliver a shock unless it is needed. However, training significantly improves confidence and the speed with which bystanders act, and is strongly recommended for anyone who may need to use an AED in an emergency. AED training is typically incorporated into first aid at work courses and can also be provided as a standalone session.
