Air Tightness Testing That Works Around Your Programme

As a main contractor, you need testing partners you can rely on. Delays to compliance testing can have a knock-on effect across the entire project, impacting handovers, client expectations and completion dates.

From individual plots to large residential developments, commercial buildings and mixed-use schemes, we provide a professional service designed around the way contractors operate.

Whether you’re looking for testing on a single site or need an ongoing testing partner across multiple developments, we can provide a consistent and reliable service.

Why Air Tightness Testing Matters

Air tightness testing is required to demonstrate compliance with Approved Document L of the Building Regulations.

The test measures how much uncontrolled air escapes through the building envelope. Excessive air leakage can affect energy efficiency, increase heating and cooling costs, reduce occupant comfort and make it difficult to achieve the required performance standards.

Successful testing helps demonstrate that the completed building performs as designed and meets the required regulatory standards.
