National Defibrillator Network – The Circuit

by | May 21, 2024 | News

Calling all clubs, groups and schools. Are the defibrillators in your organisation registered on The Circuit?

It takes less than 5 minutes to register a defibrillator on The Circuit – the national defibrillator network, and there is no cost to register – yet it could be the difference between life and death.

Thousands of families in the UK are left devasted by cardiac arrest every year. Early use of a defibrillator with CPR can more than double a person’s chance of survival. But if ambulance services don’t know where they are, they can’t direct people to them in an emergency. That’s where The Circuit comes in.

The Circuit is the national defibrillator network which provides ambulance services with visibility of the nearest defibrillator. This helps emergency call handlers direct bystanders to their nearest defibrillator when 999 is called. At a time when every second counts – you can make the difference.

How to check if your defibrillators are currently registered.

You can check whether a defibrillator is currently registered here: DefibFinder.

If you are the Guardian of the defibrillator (the person responsible for looking after it) then please register it on The Circuit.

If you are not the guardian, please ask the guardian to register.

Once registered, the guardian will receive regular email reminders to check the defibrillator status, along with other updates such as when the pads are about to expire.

If you have any questions, please contact

The Circuit has been developed by British Heart Foundation (BHF) in partnership with the Association of Ambulance Chief Executives, Resuscitation Council UK, St John Ambulance and NHS England.
