UK pharmaceutical manufacturing operates under one of the most established GMP regulatory frameworks in the world. The Medicines and Healthcare products Regulatory Agency (MHRA) enforces GMP standards aligned with the EU guidelines on GMP (EudraLex Volume 4) and the PIC/S Guide PE 009, with manufacturing site inspections that assess facility design, environmental controls, and contamination management as primary compliance criteria.
Post-Brexit, the MHRA operates as an independent regulatory authority with its own inspection programme and recognition arrangements with international partners including the FDA, EMA, and TGA. For UK pharmaceutical manufacturers, MHRA GMP compliance remains the central licence condition — and facility environment is assessed as directly as it ever was.
This article covers the compliance landscape facing UK pharmaceutical and laboratory facilities, the environmental control gaps most commonly identified in MHRA inspection findings, and how CPL Group’s engineered solutions are deployed to support MHRA audit readiness.
The UK regulatory landscape for pharmaceutical and laboratory facilities

UK pharmaceutical manufacturers must hold a Manufacturer’s Licence (MIA) issued by the MHRA and comply with the UK GMP guidelines — currently the UK version of EudraLex Volume 4, maintained by the MHRA post-Brexit. Facility design requirements are detailed in UK GMP Annex 1 (sterile products), Annex 2 (biologics), and the main guide chapters covering premises and equipment, contamination control, and environmental monitoring.
For UK laboratories — including QC labs, stability testing facilities, hospital pharmacy units, and academic research facilities — ISO 14644 clean room classification and UKAS accreditation requirements set the relevant environmental performance standards. UK Biobank, UKHSA-designated facilities, and NHS pharmaceutical manufacturing units operate under additional sector-specific frameworks.
Three compliance dimensions most commonly drive facility investment in UK pharma and lab:
- Contamination control strategy — MHRA GMP Annex 1 (2022 revision) significantly expanded the contamination control strategy (CCS) requirements, creating demand for upgraded physical contamination barriers across sterile and non-sterile manufacturing alike.
- Environmental monitoring and zone integrity — demonstrating continuous compliance between inspections, not just during pre-inspection facility upgrades.
- Cold chain compliance — maintaining validated storage conditions for biologics, ATMPs, temperature-sensitive APIs, and clinical trial materials under MHRA storage guidelines and ICH Q1A requirements.
CPL Group pharmaceutical and laboratory solutions — the full range

Clean Room Solutions
CPL Group’s Clean Room Solutions are purpose-built for pharmaceutical manufacturing and laboratory environments where contamination control is a regulatory requirement, not a preference. Systems incorporate HEPA and ULPA filtration to remove 99.99% of airborne particles, with design options that support ISO 14644 clean room classification and GMP compliance. Fully customisable in size and configuration — from compact QC lab clean rooms to large-scale sterile manufacturing suites — with modular construction that allows future reconfiguration as production requirements evolve.
Laboratory Dividers
CPL Group’s Laboratory Dividers are engineered to create defined, controlled zones within pharmaceutical and research laboratory environments. By establishing clear physical separation between workstations, sampling areas, and reagent storage, Laboratory Dividers reduce cross-contamination risk, support personnel traffic management, and contribute to GMP compliance by maintaining zone integrity during inspections. Available in a range of sizes and configurations to suit diverse laboratory floor plans, with clean, smooth surfaces that meet pharmaceutical hygiene standards.
Freezer Panels
For pharmaceutical facilities requiring reliable cold storage — whether for temperature-sensitive APIs, biological samples, reagents, or finished product — CPL Group’s Freezer Panels provide the insulated enclosure performance needed to maintain precise temperature control. Panels are engineered for pharmaceutical-grade cold store applications, supporting validated storage conditions for Schedule 4 and Schedule 8 products, biologic compounds, and clinical trial materials.
Cross Contamination Solutions
Pharmaceutical facilities running multiple product lines, handling potent compounds, or operating under changeover protocols face a heightened cross-contamination risk that layout alone cannot resolve. CPL Group’s Cross Contamination Solutions provide engineered physical barriers that prevent airborne particulate, chemical vapour, and personnel-borne contamination from crossing between zones — supporting GMP requirements for dedicated processing areas and audit-ready contamination control documentation.
Decontamination Curtains
CPL Group’s Decontamination Curtains create defined entry and egress zones that support contamination control protocols in pharmaceutical manufacturing and laboratory settings. Used at the interface between clean and controlled zones, gowning areas, and production suites, Decontamination Curtains provide a physical, auditable barrier that reinforces personnel flow protocols and reduces the risk of particulate or microbial ingress.
Chemical Splash Curtains
In pharmaceutical and laboratory environments handling solvents, reagents, and hazardous chemical inputs, Chemical Splash Curtains provide a critical layer of personnel and equipment protection. CPL Group’s chemical-resistant curtain systems are designed to contain splash events, isolate chemical handling areas, and support safe working procedures in line with WHS and laboratory safety regulations.
PVC Strip Curtains
CPL Group’s PVC Strip Curtains are deployed in pharmaceutical facilities to manage personnel and material flow between zones while maintaining environmental separation. Suitable for doorways between controlled and non-controlled areas, production entry points, and cold store access, PVC Strip Curtains reduce air exchange between zones — supporting temperature control, contamination management, and energy efficiency without impeding operational throughput.
The MHRA Annex 1 revision and its implications for UK facility design

The 2022 revision of EU GMP Annex 1 — adopted by the MHRA for UK application — introduced the formal requirement for a documented Contamination Control Strategy (CCS) as a central facility compliance document. The CCS must address facility design, equipment layout, personnel and material flow, environmental monitoring, and cleaning and sanitisation — and the physical environment must demonstrably support the claims made in the CCS.
This has elevated the importance of engineered physical contamination barriers in UK pharmaceutical facilities. Laboratory Dividers, Cross Contamination Solutions, Decontamination Curtains, and Clean Room Systems are now elements of a compliance document, not just operational conveniences. CPL Group’s product range provides the documented, certifiable facility hardware that a compliant CCS requires.

Frequently Asked Questions
What regulatory standards apply to pharmaceutical facilities in the UK?
UK pharmaceutical manufacturers must comply with MHRA GMP requirements — the UK version of EudraLex Volume 4, aligned with PIC/S PE 009. Key annexes include Annex 1 (sterile products — 2022 revision), Annex 2 (biologics), and the main guide on premises, equipment, and contamination control. Clean room environments are assessed against ISO 14644. UKAS-accredited laboratories operate under ISO/IEC 17025.
