Healthcare Ventilation Validation Services
Independent HTM 03-01 Ventilation Verification & Validation
validation
M&M Compliance Training offers expert validation services for new construction sites, refurbishment projects, and major alterations to healthcare ventilation systems throughout the UK.
Our validation ensures your ventilation installation precisely aligns with the agreed design specifications and fully complies with Health Technical Memorandum (HTM) 03-01 Part A guidelines, ensuring patient safety, operational efficiency, and regulatory adherence.
Why is Independent Validation a Mandatory Requirement?
Ventilation validation is a mandatory requirement detailed in HTM 03-01 Part A (2021), Chapter 12 “Verification and validation”. It is the formal process of ensuring installed ventilation systems meet exacting standards necessary to protect patients, staff, and visitors from airborne contamination, maintain optimal infection control standards, and uphold critical clinical environment operations.
Our validation service helps you:
- Verify conformity with HTM 03-01 Part A: Design and Validation
- Identify and resolve installation discrepancies before project handover
- Ensure patient and staff safety by achieving stringent air-quality standards
- Provide documented evidence of compliance and safety assurance
Validation and Annual Verification Under HTM 03-01
HTM 03-01 separates the validation of new installations and major refurbishments from the ongoing performance verification of existing ventilation systems. Part A covers design and validation before handover, while Part B covers operational management and performance verification throughout the life of the system. Healthcare estates teams should retain the original validation evidence and maintain a planned verification programme for critical ventilation systems.

Our Comprehensive HTM 03-01 Part A Validation Process
We provide a thorough, structured validation approach strictly following the HTM 03-01 Part A methodology:
Design Proposal Review
Before validation begins, our experienced Authorising Engineers (Ventilation) comprehensively review ventilation design proposals, ensuring alignment with HTM 03-01 Part A standards.
First-Fix Inspection
We conduct detailed inspections during the installation phase to ensure:
- AHU placement and access for maintenance
- Correct installation and sealing of ductwork
- Proper location of test points, fire dampers, pressure stabilisers, and filtration components
- Accessibility of components for ongoing maintenance, as required by HTM 03-01 Part B (Operational management)
Permeability Testing
We perform airtightness tests to confirm the integrity of critical rooms, including:
- Operating theatres
- Isolation suites
- Aseptic preparation facilities
- Critical care and containment level 3 facilities
Final Acceptance Testing
Our validation culminates in rigorous testing of fully installed ventilation systems, verifying:
- Airflow volumes and air-change rates
- Differential pressure cascades between critical areas
- Temperature and humidity control accuracy
- System filtration efficiency, including terminal HEPA filters
- Compliance of air velocities and room pressurisation
- Operational performance under both normal and setback modes
Comprehensive Validation Report
Post-validation, we provide a detailed, actionable validation report, clearly documenting:
- Validation methodology and test results
- Compliance status against HTM 03-01 Part A criteria
- Recommendations for any corrective actions required
The Tangible Outcomes of Our Validation Service
- Receive independent confirmation that your design and installation are fully compliant with HTM 03-01
- Gain certified assurance that your clinical environments are safe and fit for purpose before handover
- Obtain a detailed validation evidence file to satisfy regulatory bodies and support project sign-off
