Choosing my insulin pump

Patient information A-Z

This information is to help you consider which insulin pump would be best for you. It is for people new to pumps and for those who are due a pump upgrade. The information is correct as of date of publication (Dec 2026).

Choosing an insulin pump is a big decision

Take your time choosing your pump and fully research what is on offer. You will be offered the chance to come and see the pumps at a pump demo session which we strongly encourage you to attend, especially if this is your first pump. This will give you the opportunity to speak to the pump team who can answer your questions.

We often get asked “what pump do you think I should have?”. Nobody else can make that decision for you. All the pumps have their own unique characteristics, and everyone chooses their pump for very different reasons. You are the only person who will be wearing the pump so it’s important that you make that final decision.

For general information on insulin pumps, please visit this diabetes.org.uk (opens in a new tab).

Pump choice

We offer a wide range of pumps. If you are unable to attend a pump demo session, it is worth spending the time contacting the pump companies you are interested in for specific questions you might have.

Please take the time to consider what is important to you so that you make the right choice. Once you receive your new insulin pump, you will not be able to change your mind. After a period of four years, should you continue to meet the upgrade requirements, you will be able to choose a new pump.

Considerations when choosing an insulin pump

Insulin reservoir/cartridge size

  • Will the pump/cartridge/reservoir hold enough insulin for 3 days? If not, you may need to change the cartridge more frequently which you may not find convenient.
  • Omnipod pods can hold 200 units which must last for three days. If you require more than 60 units of insulin per day, you may not be suitable for the Omnipod 5 (please discuss this with the pump team).

Cannula choice

  • If you are new to pumps, cannulas come in different lengths e.g. 6mm or 9mm, angled e.g. variable/30 or 90 degree and materials such as steel or Teflon.
  • If you are already on a pump; are you currently using steel or angled cannulas? Does the pump you are considering offer the same choice?

Insulin

  • If you use Fiasp or Lyumjev insulin, make sure it is suitable/licensed for use in the pump you are choosing. If it is not, you may need to switch the type of insulin you use.
  • You may wish to use PumpCarts (pre-filled insulin reservoirs) – if this is the case, only the Ypsopump is compatible. PumpCarts are currently only available in NovoRapid.

Method of charging vs batteries

  • The only pumps that use batteries are: Medtronic 780G (AA) and the Ypsopump (AAA)
  • The Tandem T:Slim/Omnipod handsets use rechargeable batteries and need to be charged using a cable.

Mobile phone compatibility

  • Do you want to be able to control your pump via a mobile phone? As of 2026, there are only two systems where you can control the pump (bolus) with a phone app:
  • MyLife Ypsopump using the CAMAPS FX app
  • Tandem T:Slim

Always double check your smartphone is compatible with the insulin pump/sensor.

Other considerations

Screen size

  • Touch screen vs physical buttons
  • Sensor compatibility
  • MyLife Ypsopump: preferred sensor is Libre 3 Plus (also compatible with Dexcom G7)
  • Omnipod 5: preferred sensor is Libre 2+ (also compatible with Libre 3 Plus and Dexcom G7)
  • Minimed 780G: Instinct (or Simplera Sync/Guardian 4)
  • Tandem T:Slim: preferred sensor is Libre 3 Plus (also compatible with Dexcom G7)

Note that the Dexcom One+ is not compatible with any insulin pumps

Hybrid Closed Loop / Automated Insulin Delivery pumps

All the insulin pumps below have hybrid closed loop capability. They can deliver variable (automated) basal insulin dictated by an algorithm based on real-time CGM sensor glucose trends. Some systems are also able to give automatic corrections.

You need to continue to carbohydrate count and tell the pump before you eat or drink carbohydrates.

Some insulin pump systems require you to initiate correction doses.
