Compliance in the UK is governed by the Medicines and Healthcare products Regulatory Agency (MHRA) under the framework of Good Distribution Practice (GDP).

By 2026, these standards have been updated to reflect the complexities of Brexit and international trade. Every entity in the chain, from the primary wholesaler to the "last-mile" courier, must adhere to a Quality Management System (QMS) that is regularly audited.

Key regulatory requirements in 2026 include:

• Thermal Mapping: Every warehouse and vehicle must undergo seasonal "mapping" to identify hot and cold spots.

• Validated Equipment: Only medical-grade refrigerators and specialized vehicles with dual-redundant cooling systems are permitted.

• The Responsible Person (RP): Every licensed wholesaler must appoint an RP who is legally accountable for ensuring that the temperature-controlled integrity of the medicinal products is never compromised.
