Our recent blog, Pharmaceutical and Laboratory Facility Compliance, set out the pillars regulators expect facilities to address globally. In the UK, cold chain compliance is overseen by the MHRA under its own Good Distribution Practice framework, published in the Orange Guide (Rules and Guidance for Pharmaceutical Manufacturers and Distributors), which operates independently of the EU following Brexit while remaining closely aligned in principle.
How UK Cold Chain Rules Diverged and Converged Post-Brexit

Since leaving the EU regulatory system, the UK runs its own licensing and inspection regime through the MHRA rather than relying on the EudraGMDP database.
UK GDP still mirrors the core principles of EU GDP, but facilities now need to demonstrate compliance directly to MHRA inspectors, with UK-specific licensing such as the Wholesale Dealer’s Licence (WDA(H)).
What MHRA Inspectors Look For in Temperature-Controlled Storage

MHRA inspections examine qualification of storage equipment, temperature mapping evidence, functioning monitoring and alarm systems, and robust deviation management.
WDA(H) holders in particular face close scrutiny of how cold chain stock is segregated from ambient-temperature product and how excursions are recorded and actioned.
Where UK Facilities Commonly Fall Short

Ageing cold room infrastructure is a recurring issue at longer-established UK sites, often compounded by retrofit panel work that introduces condensation or thermal bridging.
Inconsistent documentation of alarm responses is another frequently cited gap, particularly where a facility has grown incrementally rather than been designed as a single validated system.
Engineering for MHRA Compliance

CPL Group‘s Freezer Panels are built to withstand condensation, washdown, and long-term exposure to low temperatures, with smooth, hygienic surfaces suited to HACCP-compliant environments.
The modular system is particularly useful for UK sites looking to upgrade legacy cold rooms without a full rebuild, while our Cold Storage Rooms provide a turn-key option with advanced monitoring and compliance documentation available on request for sites planning a new build.
Frequently Asked Questions

Does the UK still follow EU GDP rules for cold chain storage post-Brexit?
The UK operates its own GDP framework enforced by the MHRA, closely modelled on the same principles as EU GDP, but with separate licensing, inspections, and guidance published in the Orange Guide.
Who needs a Wholesale Dealer’s Licence for temperature-controlled storage in the UK?
Any business storing or distributing medicines at wholesale level, including cold-chain products, generally needs a WDA(H) from the MHRA, which includes scrutiny of temperature control and monitoring arrangements.
What’s a common MHRA inspection finding for cold storage?
Inconsistent documentation of alarm responses and corrective actions during temperature excursions is a frequently cited gap, often linked to ageing or retrofitted cold room infrastructure.
Can older UK facilities upgrade cold storage without a full rebuild?
Yes. Modular insulated panel systems can often be retrofitted into existing structures to improve insulation and hygiene standards while limiting disruption to ongoing operations.
Prepare for Your Next MHRA Inspection
Maintaining cold chain compliance in the UK requires validated infrastructure, continuous environmental monitoring, comprehensive documentation, and storage solutions designed to meet MHRA GDP requirements.
