Medical Device Regulatory Services

Northern Ireland is required to European Union Medical Devices Regulations (EU MDR) 2017/745 and In Vitro Diagnostic Devices Regulations (IVDR) 2017/746.

The UK Medical Device Classification

The UK Medical device classifications are based on the UK MDR 2002. Classifying the device is the very first step in the entire process of obtaining approval and launching it in the market.

Device Classification

Classification of the device is the very first step in determining the regulatory pathway for the given product. There are about 22 implementing rules for medical devices and are classified as –



Class I


Class IIa


Class IIb

Moderate to High

Class III


Similarly, for IVD, about 7 rules are implemented while classifying into the following four categories –



Class A


Class B


Class C

Moderate to High

Class D



IVD Classification –

  • General IVD
  • Self-testing IVDs
  • IVDs considered under Annex II List A
  • IVDs considered under Annex II List B

Our company specializes in medical device classification. Freyr has successfully completed device classification for over 50 companies to date in the UK.

The manufacturers will now have to appoint a UK-approved body to obtain UKCA marking. Though CE marking is allowed, it is applicable only for a certain time period. The transition timelines for the same are mentioned below –

Freyr is currently supporting many manufacturers with the post-brexit transitions.

Post-market Surveillance Requirements

Post-market surveillance requirements under UK MDR 2002 are quite stringent to ensure patient/user safety and effectiveness.  Currently, the PMS activities include reporting of incidents/findings to the MHRA. The MHRA has released comprehensive guidance on the same.

Freyr has expertise in post-marketing surveillance support in medical writing services.
