West Midlands Ambulance Service

“West Midlands Ambulance Service (WMAS) serves a population of 5.6 million people and covers an area of more than 5,000 square miles, made up of Shropshire, Herefordshire, Worcestershire, Staffordshire, Warwickshire, Coventry, Birmingham and Black Country conurbation.

“WMAS is the only ambulance service to be rated as ‘outstanding’ by the Care Quality Commission. The service responds to around 4,000 999 calls each day and employs approximately 5,000 staff.

“The service is fully supportive of Sally’s project and is pleased to be working in partnership with her as, ultimately, it will help to save lives. The quicker you start CPR and shock a patient in cardiac arrest with a defibrillator, the better the chance they have of surviving.”

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.

Register Your Defibrillator

To make registering easy, please ensure you have the following details

  • The location and surroundings

  • Make, model and serial number

  • Availability times

  • Pad expiry dates

  • Confirm it is indicating ready

Register Your Defibrillator

Once registered, this will mean it will be your responsibility to keep all information up to date and amend any details relating to the defibrillator on the NDN (National Defibrillator Network).
If you experience any technical problems, please contact the NDN Help & Support desk on 0300 330 5482 or email
Thank you so much for connecting your defibrillator to The Circuit. Defibrillators do help save lives and that depends on people like you to make them available.
