Brexit and Its Impact on UK-EU GMP Inspection Alignment

The UK’s departure from the European Union has significantly altered the pharmaceutical regulatory landscape, especially regarding Good Manufacturing Practice (GMP) inspections. Prior to Brexit, the UK operated within the EU regulatory framework coordinated by the European Medicines Agency (EMA). Post-Brexit, the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) now functions as a standalone authority. This article explores the impact of Brexit on UK-EU GMP inspection alignment, detailing the regulatory shifts, divergence challenges, and strategies for manufacturers navigating dual compliance.

Pre-Brexit Regulatory Integration

• The UK was a member of the EMA’s Inspection Coordination Group
• MHRA participated in joint inspections and mutual recognition of GMP certificates
• UK sites were listed in the EU’s EudraGMDP database
• Qualified Person (QP) batch release conducted in the UK was valid across the EU

Post-Brexit Regulatory Landscape

• MHRA now functions as an independent regulator for the UK (England, Scotland, Wales)
• Northern Ireland follows EU rules for medicinal products under the Windsor Framework
• UK GMP inspections are no longer coordinated or recognized by EMA
• EU does not automatically accept UK GMP certificates or QP batch release

UK’s Standalone GMP Framework

• MHRA adopted existing EU GMP standards as UK GMP guidance
• UK continues to align with EudraLex Volume 4 and ICH guidelines
• MHRA issues its own GMP certificates and inspection outcomes
• SOPs and validation protocols now reviewed independently during UK inspections

Impact on GMP Inspection Alignment

• Loss of automatic recognition creates dual inspection burden for manufacturers
• UK-based manufacturers exporting to the EU may face EMA inspections
• EU manufacturers exporting to the UK may require MHRA inspections
• Batch release in the UK no longer valid for EU distribution unless conducted within the EU/EEA

Role of the Mutual Recognition Agreement (MRA)

• The UK and EU currently do not have a formal MRA covering GMP inspections
• This differs from EMA’s MRAs with countries like the US, Canada, Australia, and Switzerland
• Lack of MRA requires duplicate audits and separate compliance submissions
• Pharmaceutical industry stakeholders continue to advocate for a future UK-EU MRA

MHRA Inspection Strategy Post-Brexit

• Adopted a risk-based national inspection model
• Continues to inspect UK manufacturing, importation, and testing facilities
• Maintains independent GMP certificate listings accessible on the MHRA portal
• Conducts for-cause and routine inspections similar to EMA methodologies

EU Inspection Strategy Toward UK Sites

• EMA treats the UK as a third country
• UK manufacturing sites must be listed in EU marketing authorizations
• GMP compliance must be verified through EMA/NCA inspection or trusted audit reports
• Written confirmation may be required for APIs exported from the UK to the EU

Key Differences Between EMA and MHRA GMP Expectations

• Documentation: EU expects documentation in EudraLex formats; MHRA accepts UK-compliant versions
• QP Oversight: UK QPs must be registered under MHRA; their release is not valid in EU
• Inspections: MHRA and EMA both follow ICH Q7, Annex 15, and Annex 1, but use different interpretation criteria
• Certificates: EMA uses EudraGMDP; MHRA uses standalone certificate publication

Practical Considerations for Pharmaceutical Companies

1. Evaluate whether your QP certification needs to occur in the EU or the UK depending on the distribution target
2. Maintain parallel documentation systems that satisfy both EMA and MHRA inspectors
3. Prepare for separate inspections and potential audit requests from each regulator
4. Stay updated on inspection frequency, GMP certificate renewals, and agency guidance updates
5. Train compliance teams on dual GMP frameworks and regulatory divergence points

Future Outlook and Harmonization Efforts

• Industry continues to urge the UK and EU to negotiate a mutual recognition agreement for GMP inspections
• MHRA has expressed interest in aligning with international regulatory networks such as PIC/S
• EMA continues to monitor third-country inspections and offers flexibility for pandemic-affected logistics
• Stakeholders must remain vigilant and adapt to evolving regulatory pathways

Conclusion

The UK’s exit from the European Union has led to significant divergence in GMP inspection coordination and batch release recognition. Pharmaceutical companies must now operate under two regulatory regimes—MHRA for the UK and EMA for the EU—each with its own inspection protocols, documentation expectations, and compliance pathways. Until mutual recognition is established, businesses must embrace robust dual-alignment strategies to ensure uninterrupted supply, regulatory trust, and patient safety across the UK and EU markets.
