Defibrillator & AED Testing and Inspection

AED Defibrillator Test and Inspection

If you own an AED, you’ll want to know whether it is fully operational and when any maintenance is required This is where we can help!

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

  • A full inspection and fault diagnosis
  • A dynamic test using simulated arrhythmia waveforms (where applicable)
  • 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 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 being properly looked after and that it is fully functioning and is capable of recognising and delivering a shock with sufficient energy unless you have it professionally tested.

Northwick’s test and inspection service involves specialist test equipment that puts your AED through a simulated 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 maintenance regime especially if you are not an expert and don’t know the exact condition of your device. 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 choose one of our call out options and add £60+VAT for the test and inspection.

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 test and inspection, we will advise on the equipment condition and, if appropriate, arrange for any 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.
