CGM – Costs and the systems available

How much does it cost? What systems are available?

There are two costs associated with CGM; the initial outlay (for a transmitter and receiver) and the ongoing running costs (sensors, adhesive covers if necessary, batteries and replacement transmitters). The cost varies according to which system you buy. Please follow the links below to the CGM websites for up-to-date costs. Starter kits including transmitters and receivers are in the region of £1,000, or for systems integrated into an insulin pump that you already have, around £500 for the transmitter. Most sensors cost in the region of £40 – £60 each. If that is totally out of your reach, consider the Abbott Freestyle Libre, which is not CGM but will allow you to access continuous glucose data.

Information about NHS funding for CGM can be found on this page.

The following systems are available in the UK

System Profile Access Cost
Standalone system CGM receiver + transmitter but not pump integrated Direct purchase from the company To obtain details of costs, contact the companies providing CGM. Contact details are available below.
Integrated system CGM receiver integrated into pump You may need to confirm support from your healthcare team for a transmitter
Disposable sensors Recommended 5-7 day use, depending on the brand, possibly longer for many users Might receive funding for some or all sensors


  • You are likely to get the most benefit from CGM if you have support from your diabetes team
  • Standalone systems can be used with any pump or with MDI
  • It is possible to pay the initial costs of a long-term CGM system yourself and receive full or partial NHS support for the sensors

The standalone systems show the results on a portable receiver which is about the size of a mobile phone. The integrated systems show the results on the integrated pump’s screen.

Common features include:

  • a display of current glucose level
  • a trend arrow indicating whether glucose is falling or rising
  • trend information showing results over the last three, six or 24 hours
  • alarms to indicate high or low glucose or rapid change. Some systems provide early warning alarms if glucose levels are likely to fall too high or low. Alarms can usually be set by the user at the level they want. There may be a choice of an audible or vibrating alarm
  • ability to download data and view graphs and statistics.
