Elmhurst’s Level 1 Airtightness Testing training offers new entrants, as well as existing energy and retrofit professionals, the essential skills and knowledge required to conduct full air pressure/airtightness tests for Level 1 UK properties. In addition, learners completing this course will earn 10 hours of Continuing Professional Development (CPD).
During this three-day course, you will gain a comprehensive understanding of the industry, covering key principles of testing and the regulations and standards that govern the process. You will also receive hands-on experience with the equipment, which will be introduced and explained during the classroom-based/practical part of the course.
Upon completion, you will be qualified to conduct Level 1 air pressure testing for buildings, covering simple structures up to 4,000 m³.
Course Delivery: Important Information
Elmhurst has streamlined the qualification process to maximise your hands-on learning experience for delivering airtightness 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.
How It Works:
- 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. - Complete On Demand Theory Training (2 Days)
After booking, you’ll receive access to five 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 2 days to complete. - Attend Practical Day (1 Day)
Spend a day applying your knowledge through hands-on experience with blower door or pulse testing equipment. - Complete 3 Live Test Cases
After the practical day, you’ll need to conduct airtightness tests on three properties of your choosing. - Receive Your Qualification
Once your live test cases are successfully completed, you’ll receive your official qualification.
Upon qualifying, you will then be eligible to join the Elmhurst Airtightness Scheme, enabling you to certify the dwellings you test.
