Guaranteeing the performance of your home

We inspect and independently performance test every Beattie Passive house to ensure the highest standards of construction are maintained.

We carry out stringent air tightness, thermal imaging and sound migration tests following structural completion and only upon reaching our superior Beattie Passive design standards, will we issue a quality assurance certificate. We test at the right time, every time.

Beattie Passive inspects and tests each build for the following:

Air Tightness
Sound Migration/Acoustics
Thermal image for continuity of insulation
Structural Testing

These tests are performed at crucial stages of the build process. Through these ongoing and stringent testing procedures, each Beattie Passive build assures the highest level of construction to meet the requirements for final certification.

For those building the system themselves these test provides peace of mind that the building has been built correctly and ensures any minor defaults can be rectified with minimal disruption and cost to the overall build.


A full report showing all test results and statistics is supplied by Beattie Passive on completion. The report is stamped and signed to confirm all results are genuine and meet the standards required for Passivhaus certification.

“With normal builds we usually find several gaps, spend two days smoke testing to rectify and achieve an overall score of between 1 and 2. At the housing association site in Fife, Plot 1 achieved an initial air test reading of 0.4 which is amazing. We have not seen results like this before in the UK. ”
