DEFIBRILLATOR SUPPORT HUBA practical guide for schools and early years settings
Not just because a battery or pad quote is expensive.
First identify the exact model, confirm that compatible parts and technical support are still available, then compare the full cost of keeping it with the whole-life cost of replacement.
General guidance only. Follow your AED manufacturer's instructions and seek appropriate technical support for your exact device.

The decision is about readiness and remaining support. An expensive consumable for a very old, unsupported or discontinued AED can justify comparing replacement, but an exact model check must come first.
STEP 1
A photograph of the model label prevents most compatibility mistakes.
Capture the manufacturer, exact model, serial number and any existing part numbers.
Record pad and battery expiry dates and check the ready or fault indicator.
Never buy on appearance alone. Confirm the exact compatible part number.
Ask the manufacturer or an appropriate technical supplier whether the model is supported.
Consider location and access, ongoing recorded checks, cabinet condition and whether the AED is correctly registered on The Circuit.
STEP 2
The device is at or beyond its documented anticipated service life.
Correct pads or batteries are no longer available.
The manufacturer no longer supports the model or necessary updates.
A costly consumable for a very old device makes replacement competitive over its remaining life.
These are reasons to compare, not a clinical or device-specific recommendation.
STEP 3
Ask the supplier to put every answer in writing.
Exact make and model
Everything included: pads, battery, case, sign and preparation kit
Adult and paediatric capability
Pad and battery prices and expected replacement intervals
Warranty and anticipated service life
Software support and any servicing or maintenance charges
Check the proposed AED against the official DfE minimum specification before ordering. Headline price alone does not show value.
CURRENT DFE GUIDANCE
The current publication is Automated External Defibrillators (AEDs): Guidance for schools, January 2025. The purchasing section is on printed page 15 (PDF page index 14).
It describes a reduced-cost purchasing arrangement negotiated by the Department for Education with NHS Supply Chain. Eligible settings include schools, nurseries, playgroups and holiday or out-of-school providers.
Buying through the arrangement is voluntary. Appendix A provides a useful minimum specification when comparing other offers.

The BHF online shop lists compatible pads and batteries for several brands. It is useful only when the device is supported and precisely identified; it does not guarantee a compatible part for every discontinued AED.

Register the location, accessibility, model details, pad expiry and ready status. Update the record whenever the AED is taken out of service or returned to readiness.
