EU GMP Premises and Equipment: Audit Guide

In short: This guide summarizes selected premises and equipment topics to review before an EU GMP audit of a human medicinal-product site. Use it to organize a site-specific gap assessment; it is not a complete audit checklist or a source of universal engineering limits.

Scope and current applicability

The guide summarizes EudraLex Volume 4, Part I, Chapter 3, “Premises and Equipment,” which the European Commission lists as in operation since 1 March 2015. The applicable requirements depend on the products, processes and risks at the site, and other chapters or product-specific annexes may also apply. (European Commission, EudraLex Volume 4, Part I, Chapter 3 (in operation since 1 March 2015); official Chapter 3 text)

This article focuses on human medicinal products. The Commission’s current EudraLex page states that Volume 4 applies to veterinary medicinal products only until 15 July 2026 and lists Commission Implementing Regulation (EU) 2025/2091 as applying from 16 July 2026. Veterinary sites should use the applicable current veterinary GMP instrument. (European Commission, EudraLex Volume 4 applicability and current veterinary GMP information, accessed 19 October 2026)

Premises: review the design and controls

General conditions and access

Review whether the site’s location and protective measures limit contamination risks, whether premises are maintained and cleaned under written procedures, and whether lighting, temperature, humidity and ventilation suit the products, operations and equipment. Check pest exclusion and controls that restrict unauthorized entry to production, storage and quality-control areas. (EudraLex Volume 4, Part I, Chapter 3, §§3.1–3.5 (2015).)

Production layout and cross-contamination

Assess whether the layout supports the sequence of operations, orderly placement of equipment and materials, effective cleaning, and prevention of mix-ups and cross-contamination. Where dust or exposed materials create a risk, review the controls used for containment and cleaning. Walls, floors, ceilings, services and drains should be suitable for the work and maintainable without creating contamination risks. Production ventilation should suit the products handled and the operations performed. (EudraLex Volume 4, Part I, Chapter 3 (2015).)

Chapter 3 specifies dedicated, self-contained facilities for particular products and describes the conditions that apply to those cases. Review the relevant product-specific provisions alongside Chapter 3 before deciding what dedicated areas are needed. (EudraLex Volume 4, Part I, Chapter 3 (2015).)

Storage areas

Check whether storage capacity supports orderly separation of starting and packaging materials, intermediates, bulk and finished products, and materials awaiting a quality decision. Review whether special storage conditions are defined, checked and monitored; whether receipt and dispatch areas protect materials from weather; and whether quarantine, rejected, returned and recalled items have controlled status and access. Review sampling arrangements and secure storage of highly active materials and printed packaging components where relevant. (EudraLex Volume 4, Part I, Chapter 3 (2015).)

Quality-control and ancillary areas

Check that the laboratory layout fits its work and provides sufficient space and storage to prevent mix-ups. EU GMP says control laboratories are normally separate from production and highlights additional separation for biological, microbiological and radioisotope laboratories. Consider whether sensitive instruments need rooms protected from vibration, electrical interference or humidity. Review ancillary spaces, changing and washing facilities, toilets, and maintenance workshops against the work performed and the applicable Chapter 3 provisions. (EudraLex Volume 4, Part I, Chapter 3 (2015).)

Equipment: review intended use, cleaning and upkeep

Check whether equipment is designed, located, installed and maintained for its intended purpose; whether repairs can be performed without putting product quality at risk; and whether cleaning procedures and storage conditions are suitable. Product-contact parts should not adversely affect product quality. Confirm that balances and measuring devices are suitable for their tasks and that measuring, weighing, recording and control devices are calibrated and checked at defined intervals using appropriate methods. Keep adequate records of those checks. (EudraLex Volume 4, Part I, Chapter 3, “Equipment” (2015).)

Review pipe identification, water-system controls and the status of defective equipment. The Chapter 3 text calls for fixed pipework to be identified by contents and, where relevant, flow direction; it also describes written procedures for sanitizing specified water pipes and for addressing microbiological action limits. Defective equipment should be removed from the area where possible or clearly identified as defective. (EudraLex Volume 4, Part I, Chapter 3 (2015).)

For qualification planning, use the current site requirements and risk assessment to define the evidence needed for the facility and equipment. EudraLex Volume 4 Annex 15, “Qualification and Validation,” has been in operation since 1 October 2015. (European Commission, EudraLex Volume 4, Annex 15 (2015))

Preparing a site-specific evidence review

Example in-house criterion (not a pharmacopoeial requirement): Prepare an evidence index that links each area or equipment group to its approved drawing or specification, risk assessment, maintenance and cleaning records, calibration or qualification evidence, and open corrective actions. Adapt the index to the site’s scope and document-control system.

Use the following questions to focus the review:

Can staff explain how the room layout and process flow reduce the risks identified for the product and operation?
Are environmental conditions and special storage requirements monitored against approved site limits?
Can the site show the status and segregation controls for quarantined, rejected, returned or recalled items?
Are equipment cleaning, maintenance, calibration and qualification records complete and attributable to the equipment?
Are defects, alarms and deviations assessed, escalated and closed under approved procedures?

For batch-associated documentation, EudraLex Volume 4, Part I, Chapter 4, §4.11 requires retention for one year after batch expiry or at least five years after Qualified Person certification, whichever is longer. Apply any longer product-specific or local requirement. Other equipment records follow the applicable document-retention schedule. (EudraLex Volume 4, Part I, Chapter 4, §§4.10–4.11 (January 2011))

Frequently asked questions

Does Chapter 3 give one temperature or humidity setpoint for every manufacturing site?

No. It calls for conditions appropriate to the products, manufacturing and storage activities, and equipment. The site should establish its controls for its specific operations under the applicable GMP framework. (EudraLex Volume 4, Part I, Chapter 3, §3.3 (2015).)

Must every process use dedicated premises and equipment?

Chapter 3 specifies dedicated and self-contained facilities for particular products and refers to additional product-specific provisions. Read the applicable clause and annex before deciding what segregation is required; do not treat a summary checklist as a universal design rule. (EudraLex Volume 4, Part I, Chapter 3 (2015).)

Is this checklist suitable for a veterinary medicinal-product audit in 2026?

Check the current veterinary GMP regime before using it. The European Commission’s EudraLex page says Volume 4 applies to veterinary medicinal products only until 15 July 2026 and lists Regulation (EU) 2025/2091 from 16 July 2026. (European Commission, current EudraLex applicability information)
