ABOUT
At VSS, we specialise in providing comprehensive ductwork leakage testing services for commercial and industrial clients in all sectors including education, healthcare, hospitality and manufacturing.
Our highly qualified engineers use state-of-the-art equipment and techniques to accurately detect leaks in your ductwork systems. Identifying and repairing such leaks is vital for improving efficiency, reducing energy costs and ensures compliance with TR19 regulations.
We provide detailed reports and expert advice to help you maintain airtight, efficient ventilation systems and avoid costly energy wastage or system failures.

WHY IS IT IMPORTANT?
Leakage testing is critical to maintaining a safe, efficient and compliant ventilation system. Undetected leaks can reduce airflow efficiency, increase energy consumption and allow contaminants to enter your air systems.
Why it’s important:
- Improved energy efficiency: Prevent energy loss by locating and sealing leaks to reduce operational costs.
- Enhanced air quality: Avoid infiltration of dust, pollutants and unconditioned air.
- Regulatory compliance: Meet TR19 standards and Workplace (Health, Safety and Welfare) Regulations 1992 requirements.
- System longevity: Detect and address issues early to extend the life of your ductwork and HVAC equipment.

LEGISLATION & COMPLIANCE
Keeping your ductwork airtight isn’t just best practice – it’s a compliance requirement. Facilities managers must ensure ductwork systems are tested and maintained in line with recognised industry standards, including:
- DW/143 – BESA’s standard for the testing of ductwork leakage by pressure testing.
- DW/144 – specification for sheet metal ductwork, setting requirements for construction and leakage classes.
- BS EN 12237 / BS EN 1507 - European standards covering circular and rectangular ductwork performance, including airtightness.
- Building Regulations Approved Document F (Ventilation) - requires adequate system performance and efficiency, supported by leakage testing.
- Workplace (Health, Safety and Welfare) Regulations 1992 - obliges building operators to provide safe, clean, and effective ventilation.

OUR
PROCESS
Our duct leakage testing is designed to minimise disruption to your daily operations while delivering precise results.
- Preparation: We seal off all duct outlets and inlets to ensure accurate pressure testing.
- Testing: Using calibrated equipment, we pressurise the duct system to identify leaks and measure leakage rates.
- Reporting: Receive comprehensive test reports including leakage measurements, defect logs, and digital certification for your records.
- Solutions: Our expert technicians provide solutions for any issues identified, including sealing leaks with a breakthrough sealing technology called Aeroseal.
