Course Delivery: Important Information

Elmhurst has streamlined the course delivery process to maximise your hands-on learning experience for delivering Airtightness and Background Ventilation Tests. To make the most of your instructor-led practical training day, it’s essential to complete the On-Demand Theory Training before attending. Please note: Failure to complete the theory modules in advance may result in forfeiting your place on the practical day.

  1. Book Your Practical Day
    Choose a date from the available options below. Please note, if you are wanting to see both blower door and pulse testing equipment, you will need to book each practical day (2-days). Please contact the training team to discuss further.
  2. Complete On Demand Theory Training (2 Days)
    After booking, you’ll receive access to six theory modules, which must be completed before your practical day. A full module breakdown is available in the dropdown below. We expect that this part of the course will take approximately 2 days to complete.
  3. Attend Practical Day (1 Day)
    Spend a day applying your knowledge through hands-on experience with blower door or pulse testing equipment. You will also have a competency test on this day.
