Register your defibrillator

What is The Circuit?

When cardiac arrest strikes, CPR and defibrillation can help double someone’s chances of survival. But many defibrillators never get used because emergency services don’t know where they are or how to access them.

That’s why they need to be registered on The Circuit – the national defibrillator network. It’s connected to every Ambulance Service in the UK and allows them to direct bystanders to the nearest defibrillator to help save lives.

Although NHS Ambulance Services already have defibrillator databases for their area - The Circuit will connect them together to provide a single national view.

Why is registering your defibrillator on The Circuit so important?

There are currently tens of thousands of defibrillators in public and private locations across the UK but to date they are used in less than 4% of cardiac arrests. If the Ambulance Service know where it is, it’s far more likely to be used.

Better knowledge and data about their locations could make the difference between life and death – that’s why we need you to register it on The Circuit.

It’s as simple as that.

How do I register?

Registering your defibrillator on The Circuit is quick and simple.

  1. Set up your account
  2. Register your defibrillator
  3. You're all ready
  • You will need to know the location and surroundings of the defibrillator
  • You will need the brand, model and device serial number
  • You will need to know when the defibrillator is accessible
  • You will need to know when the pads expire and if the battery displays its ready signal i.e. a green light, so we can understand if its emergency ready

Early CPR and defibrillation can double a person’s chances of surviving an out-of-hospital cardiac arrest. In too many cases, the location of a defibrillator is not known when it is needed most.

Yes – you can register up to 10 defibrillators. If you have more than 10 your local ambulance service will be notified and will increase your limit.

If you work for a commercial organisation that owns multiple defibrillators, it’s best if each one is registered by the person responsible for it. At the initial registration stage you'll receive an individual confirmation for each defibrillator registered. If all defibrillators are registered at the same time we'll combine the information to ensure you are not inundated with multiple emails and you’ll receive just one email reminder to check all your defibrillators and update their status on The Circuit.

If you are unsure about how to manage multiple defibrillators please contact us on 0300 330 5482.

We just need you to decide amongst yourselves who will be the main point of contact (or primary guardian). Once registered, the primary guardian can then invite others to become secondary guardians to help manage the defibrillator.

Currently the UK’s 14 different Ambulance Services manage local defibrillator databases for their area. The Circuit will effectively bring these together to provide a single national view of where defibrillators are located as well as identify where there are gaps in coverage.

The Circuit will replace your local Ambulance Service database so it’s important that you do register your defibrillator on The Circuit otherwise they won’t know where it is.

It’s fairly likely it will be used on someone associated with or visiting your building. It’s useful to register it so, in the event of needing to call 999, the call handler can calmly guide the caller through exactly where it is in your building so that it can be located quickly.
