UK PMS Regulation SI 2024 No. 1368 Effective Starting Today

16 June 2025

The new UK Post-Market Surveillance (PMS) legislation is available: HERE

Overview

It introduces:

  • New vigilance terminology and reporting timeframes
  • Requirement to develop a PMS system, including PMS Plan and subsequent reports (and how the PMS data should be considered in other aspects of the device, e.g., design and manufacturing, evaluation of clinical data, etc.)
  • Trend Reporting, which is the requirement to report if there are any “significant increases in the frequency or severity of incidents involving a device if…that increase could have a significant adverse impact on the required risk analysis” and “any significant increase in expected erroneous results in comparison to the stated performance of the device in the instructions for use [for IVDs].

The requirements are generally aligned with the EU MDR/IVDR. This includes the new vigilance terminology and reporting timeframes, as well as admin statements, e.g., the PMS Plan must be “clear, organised and searchable”.

That said, there are a few differences from the EU MDR/IVDR. For example, the Post-market Surveillance Report (Class I medical devices and Class A & B IVDs) must be produced within 3-years of the device being placed on the market/put into service and updated every 3-years thereafter. Meanwhile the MDR/IVDR does not define a specific timeframe, although 3-years is generally considered best practice.

The regulation also provides an itemized list of which sections are applicable to custom-made devices under Section 44ZD.

Timing

The new PMS requirements come into force six (6) months after the day on which it was made, i.e., 16 June 2025.
