Registering a Defibrillator


Defibrillation, combined with effective CPR is the only form of treatment for cardiac arrest casualties. Providing treatment within 3-5 minutes of collapse increases the survival chance from 6% to 74%.

Many defibrillators are not known to the ambulance services. The Circuit has been developed by the British Heart Foundation (BHF) and is a National Defibrillator database that ambulance services are connected to. By registering your defibrillator this provides Ambulance Control Centres across the UK with your device's location which can then be provided to 999 callers when reporting a cardiac arrest emergency.

At the time of the call, Control Centre Staff ensure Cardiopulmonary Resuscitation (CPR) has commenced and will advise the defibrillator's location. This helps to ensure rescues are in line with the Chain of Survival, ensuring chest compressions are delivered whilst a defibrillator is located.


What Do I Need to Register my Defibrillator?

To successfully register your defibrillator, you will need to provide your local ambulance service with:

  • Organisation Name
  • Address
  • Contact Name
  • Contact Number and email
  • Location of the defibrillator and door code (if locked)
  • Make, model and serial number of the defibrillator
  • Any restricted hours (you can still register even if your unit is only available on certain days/hours)

In the event of an emergency, only the device's location is provided. No information regarding the ownership of the defibrillator is shared.

Where do I Register my Defibrillator?

Please register your defibrillator on The Circuit.  This is a national network that is connected to ambulance services across the UK.
