Regulation - General medical device and active implantable medical devices

If your product is a general medical device or an active implantable device, you need to determine which ‘class’ your device is in:

  • Class I - generally regarded as low risk
  • Class Ila - generally regarded as medium risk
  • Class llb - generally regarded as medium risk
  • Class Ill - generally regarded as high risk

If your product is a general medical device or an active implantable device and it is in class IIa, IIb, III (or is a class I device that is sterile or has a measuring function) then you will need to contact a UK approved body or EU notified body. They can carry out the necessary assessments to ensure your device meets the regulatory requirements.

UK approved bodies can certify devices for the UK market by issuing an UKCA certificate. This is an UK product marking (introduced in January 2021) for goods placed on the market in Great Britain. The UKCA mark covers most goods which previously required the CE marking. The UKCA mark is not recognised by the EU market, to certify a device for both UK and EU markets you will need to use an EU notified body. Find out more about using the UKCA marking.

The UK approved bodies are designated by the MHRA to ensure that manufacturers comply with the regulations set out in UK MDR 2002. If the device meets the regulatory requirements, then the UK approved body has the authority to issue an UKCA certificate. The manufacturer should add the UKCA mark to their device and register the device with the MHRA. The device can then be placed on the Great Britain market.

If you have a class I general medical device that is not sterile and does not have a measuring function, then you can self-certify your device for the UKCA as outlined below:
