AED / Defibrillator Test and Certification

If you are responsible for looking after a defibrillator or AED, you’ll want to know whether it is currently fully operational and when any maintenance is required so as to be sure that it is always fit for use. This is where we can help!

Northwick’s Defibrillator / AED  service inspection test and certification provides you with:

  • A full service, inspection and fault diagnosis
  • A dynamic test using simulated arrhythmia waveforms
  • Shock test and measurement of actual discharged energy
  • An inspection certificate
  • Due date for the next inspection
  • Advice on how to do your own daily checks
  • Product familiarisation so that you are confident in handling it and using it!

AED’s and Defibrillators require regular inspection and servicing to avoid problems that can inhibit operation at a critical moment. Status indicators must be checked and batteries and electrode pads must be changed periodically. Whilst many devices will “self-check”, there is no way to independently verify that your device is fully functioning  and is capable of recognising and delivering a shock with sufficient energy unless you have it professionally tested.  

Northwick’s service inspection test uses specialist test equipment that puts your AED through a simulated real-life cardiac event and checks that your device will correctly recognise heart arrhythmia patterns, respond and shock when required. 

This is an ideal way to begin your AED or defibrillator maintenance regime especially if you are not an expert and don’t know the exact condition of your equipment. There is no long term contract to worry about, no hidden charges and no need to send us your device. Simply use the links below to book an engineer or ask an expert. 


For an onsite engineer visit, simply book a call out and add £60+VAT for the service inspection and certification.

Alternatively, post* your device to us we will complete the inspection for £60+VAT plus return postage, packing and insurance. 

*Please be sure to remove and separately pack the batteries if posting your device

In either case, any repairs or replacement parts (if required) are charged extra.

Following the inspection, we will advise on the equipment condition and, if appropriate, arrange for any repairs or replacements parts according to the manufacturer’s specification. We will issue a certificate to confirm what has been inspected which will include the due date for the next inspection. Please note that our inspection certificate does not provide you with efficacy risk cover in the event of your AED/Defibrillator fails to perform its intended function at any time. You are advised to refer to your own insurers if you require cover for efficacy risk.
