Air Tightness Testing Services
At ProCerts, we offer professional Air Tightness Testing (also known as Air Permeability Testing) to help developers, landlords, and property owners meet the requirements of Approved Document L of the Building Regulations.
Air tightness testing measures the amount of uncontrolled air leakage through gaps, cracks, and openings in the building envelope. This test is essential for demonstrating compliance with energy efficiency targets, reducing heat loss, and improving overall building performance.
Using calibrated blower door testing equipment, our accredited testers provide accurate results and clear guidance to help your project achieve a pass on the first attempt.
We work with:
- Developers & Builders – pre-completion testing for Building Control compliance.
- Landlords & Property Managers – improving energy performance ratings for rental properties.
- Commercial Property Owners – meeting energy efficiency regulations in offices and retail units.
- Self-Build Projects – ensuring compliance before sign-off.
