B. Regs Air Test

A B. Regs air test verifies that your new build property meets the airtightness standards set out in Part L of the Building Regulations. Our certified testers measure air leakage rates and provide a detailed report to support building control submissions and compliance checks.

PassivHaus Test

For projects aiming for PassivHaus certification, precise air tightness is critical. Our team performs specialist PassivHaus air tests to ensure your building meets the rigorous target of ≤0.6 air changes per hour, providing confidence that your property achieves optimal energy performance.

Existing Dwelling Test

Air tightness testing isn’t just for new builds. We also test existing properties to identify leaks, assess insulation performance, and recommend improvements. This helps homeowners and landlords enhance comfort, reduce energy bills, and ensure compliance with energy efficiency regulations.

Mid-Build Audits

Performing mid-build air tightness audits allows issues to be identified and addressed before completion. Our team works alongside contractors during construction to check for potential leaks and verify that workmanship meets required standards, avoiding costly remedial work later.

Retests

If an initial air tightness test fails to meet the required standard, we provide professional retesting services. Our team identifies problem areas, advises on remedial solutions, and ensures your property passes subsequent testing efficiently, keeping your project on track.

Other Key Testing Considerations

When carrying out residential air tightness testing, we also take into account:

  • All floors, walls, roofs, and openings for potential leaks

  • Window and door frame sealing

  • Ventilation system performance

  • Thermal bridging at junctions

  • Utility penetrations

  • Structural elements exposed to external air

  • Compliance with local and national building regulations
