Air Tightness Testing

Testing to Part L of the building regulations.

As a registered member of the Air Tightness Testing and Measurement Association (ATTMA), we are approved to carry out air tightness testing domestic and commercial building types.

This ensures new homes and buildings are energy efficient and fit for purpose. We test to level 1 residential, commercial  and other dwellings up to 4,000 cubic metres.

Air Tightness Testing (also known as air leakage testing) is designed to measure the air permeability of a building. Excessive levels of air leakage can cause heat loss, which in turn has an adverse effect on a building’s energy efficiency and thermal performance. Meeting the specified targets for air tightness is a key requirement for building contractors to be fully Part L compliant.

Ventilation Testing

Testing to Part F of the building regulations.

Testing and commissioning actual performance of ventilation in domestic and commercial premises.

Part F Building Regulations 2010 introduced the requirement to verify practical performance of ventilation in new dwellings against design.

This requires validation of airflow measurements for every dwelling constructed under this edition of the Building Regulations as well as ensuring that the system has been configured correctly.

NICEC certificate of competence in the the installation and commissioning of domestic ventilation systems.



Air Testing South West based in Dorset, provides a complete building testing compliance package. With over 30 years experience in the construction industry, we carry out testing across the south west and the midlands.

Please contact us by telephone or email for prices.

In addition to Air Tightness Testing, Ventilation Testing and Sound Testing, we undertake:

AIR, VENTILATION AND SOUND TESTING to Building Regulations parts E, F & L.

Sound Testing

Testing to Part E of the building regulations.

Testing new builds and conversions to demonstrate compliance with Part E of the building regulations.

Building Regulations asks that dwellings are tested before completion (pre-completion testing).

To demonstrate suitable sound insulation. In compliance with “Approved Document E of the Building Regulations for England and Wales – Resistance to the Passage of Sound”.

Under Part E, a sample of units in new dwelling developments and refurbishments will require testing to demonstrate levels of sound insulation unless registration of the development with robust details has been undertaken.
