UK / Medical Devices
The MHRA notified the draft Medical Devices (Amendment) Regulations 2026 to the WTO on 8 May 2026. If adopted, Unique Device Identification (UDI) and electronic instructions for use would become compulsory for all medical devices and IVDs placed on the Great Britain market from 1 June 2027 — a GB-specific requirement, distinct from the EU's EUDAMED system.

If adopted as drafted, all medical devices and in vitro diagnostic (IVD) products placed on the Great Britain market from 1 June 2027 would need to carry a Unique Device Identifier — a structured code enabling precise identification and traceability of the device throughout its lifecycle, from manufacture through post-market surveillance. The draft would also permit instructions for use to be supplied electronically instead of, or alongside, printed paper, which is a meaningful packaging and labeling-cost change for manufacturers currently shipping bulky paper IFUs with every unit.

This isn't an isolated rule — it's one part of a broader UK medical device regulatory reform. The MHRA published the draft Medical Devices (Amendment) Regulations 2026 alongside a wider modernisation of the future UK regulatory framework, including transitional periods for existing devices and a planned international reliance pathway (allowing GB approval to lean on approvals already granted by trusted overseas regulators) anticipated to take effect in 2028. Manufacturers already tracking the UK's post-Brexit medical device framework should read the UDI mandate as one component of that larger reform, not a standalone change.

Don't assume EU UDI compliance covers you here. The EU's own UDI requirement runs through EUDAMED, which became mandatory for medical devices and IVDs on 28 May 2026 under the EU MDR/IVDR framework — a system we cover on our EUDAMED page. The UK's draft UDI mandate is a distinct, GB-specific obligation under the UK Medical Devices Regulations 2002 (as amended), with its own identifier format and registration expectations still being finalised. A manufacturer selling into both the EU and GB markets should plan for two separate UDI compliance tracks, not one shared registration.
The draft proposes a 3-year transition period for general medical devices and a 5-year transition period for IVDs, both intended to give manufacturers already placing devices on the GB market time to build UDI assignment, labeling and traceability into existing production and quality-documentation processes, rather than facing a hard cutover on the effective date. Exactly how the transition windows are measured (from adoption, from the effective date, or per-device-class) is one of the details still to be confirmed in the final adopted text.

No — as of August 2026 this is still draft legislation. The MHRA notified the draft Medical Devices (Amendment) Regulations 2026 to the World Trade Organization on 8 May 2026, the comment period closed 7 July 2026, and adoption is expected in December 2026, subject to UK Parliament approval. Treat the June 2027 date as a planning target, not a confirmed deadline, until adoption is confirmed.
All medical devices and in vitro diagnostic (IVD) products placed on the Great Britain market from 1 June 2027 would need to carry a Unique Device Identifier (UDI) enabling precise identification and traceability throughout the device's lifecycle. The draft regulations would also permit instructions for use to be provided electronically instead of, or alongside, printed paper.
The draft regulations propose a 3-year transition period for general medical devices and a 5-year transition period for in vitro diagnostics (IVDs). Exactly how each window is measured is still to be confirmed in the final adopted text. This gives manufacturers already selling into GB a runway to build UDI assignment and labeling into their existing production and documentation processes rather than requiring an overnight switch.
They are separate systems. The EU's UDI requirement runs through EUDAMED, which became mandatory for medical devices and IVDs on 28 May 2026 under the EU MDR/IVDR framework. The UK's draft UDI mandate is a distinct, GB-specific requirement under the post-Brexit UK Medical Devices Regulations 2002 (as amended), not an extension of EUDAMED. A manufacturer selling into both markets should expect two separate UDI compliance obligations, not one shared system.
If adopted as drafted, the UDI and e-IFU requirements would apply to medical devices and IVDs placed on the Great Britain market from 1 June 2027 onward, covering both UK-based manufacturers and non-UK manufacturers placing devices on the GB market. The regulations sit within a broader MHRA reform package covering the future UK medical device regulatory framework, including an international reliance pathway anticipated to take effect in 2028.
Tracking a draft regulation through WTO notification, comment period and adoption isn't something most device manufacturers have time to do alongside actually building product. We fold UK MHRA reform monitoring into the same market-access engagement as EU EUDAMED, CE/UKCA and RED cybersecurity work, so a device programme doesn't get caught out when a draft becomes final law.
