Delivering compliant, effective ventilation performance through testing and verification.
Mechanical Extract Ventilation (MEV) systems must be properly commissioned and balanced to ensure they achieve the airflow rates required under Part F of the Building Regulations.
MES Building Solutions provides MEV commissioning and compliance support, ensuring installed systems perform as designed. We work with contractors and installers to verify airflow performance, identify issues, and provide clear certification for Building Control.
Our approach focuses on practical coordination and efficient testing, helping projects achieve compliance without delays or rework.
Pre-Commissioning Advice
Advice to ensure systems are correctly installed, accessible, and ready for commissioning
Airflow Testing & Balancing
Measurement and adjustment of airflow rates at terminals to meet design requirements
Performance Verification
Confirmation that installed systems achieve required extract rates across all wet rooms
Certification & Reporting
Provision of commissioning certificates and documentation to support compliance and sign-off
Why MEV Commissioning Matters
Correct commissioning ensures ventilation systems deliver consistent, reliable airflow, supporting indoor air quality and regulatory compliance.
Without commissioning, systems may underperform; leading to failed inspections, poor air quality, and costly remedial works.
