What is Air Tightness Testing?

Air tightness testing measures how much air leaks from a building through gaps, cracks, and other openings. This is crucial for energy efficiency and is a legal requirement for new buildings under Part L of the Building Regulations.

Our professional testing service uses state-of-the-art equipment to accurately measure air permeability and identify areas where improvements can be made. This can help you achieve up to 30% energy savings and improve your SAP rating by up to 5 points.

Whether you're a developer needing compliance testing for a new build, or a homeowner wanting to improve your property's energy efficiency, our expert service ensures accurate results and practical recommendations.
