Type: Guidance
Published: July 3, 2026

> This regulatory guidance outlines the legal obligations for pharmaceutical companies under Regulation 267 of the Human Medicines Regulations (2012) regarding the submission of packaging and leaflet mock-ups to the UK licensing authority. The framework applies to both initial license applications and any subsequent modifications that are not linked to changes in the Summary of Product Characteristics (SmPC). To ensure compliance, license holders are required to submit visual representations of their product labeling and patient information leaflets for official review. The guidance establishes a dual-track submission system: the standard procedure involves a self-certification route, which provides an efficient mechanism for companies to register minor updates. However, more significant changes categorized under classifications P1 through P4 necessitate a full assessment by regulatory officials to verify accuracy and safety. While this document does not reference specific company names, inspection dates, or individual violations, it sets the mandatory standards for all applicants in the UK market. Entities must carefully evaluate their proposed changes to determine if they qualify for self-certification or require the more rigorous full assessment path. Adhering to these requirements is essential for maintaining a valid marketing authorization and ensuring that patient-facing materials remain clear, accurate, and legally compliant throughout the product lifecycle.

## Content

Regulation 267 of the Human Medicines Regulations (2012) sets out the requirement for the submission of mock-ups of packaging and leaflets to the licensing authority, as part of an initial licence application and subsequently to register any changes that are not connected with a change to the Summary of Product Characteristic (SmPC). The default route for registering changes to the label and/or leaflet is via a self-certification, unless the proposed updates fall into the categories P1-P4, where a full assessment is required.
