Certified Air Tightness Tester Scheme
Introduction
Under revised building regulations which came into force in January 2008, air tightness testing is mandatory for all dwellings. Further improvements to backstop performance levels have come into effect with the publication of the updates to the Technical Guidance Document to the Building Regulations Part L - Conservation of Fuel and Energy - Dwellings (2011) and Part L - Conservation of Fuel and Energy - Dwellings (2017)
NSAI operates a registration scheme that certifies testers to I.S. EN ISO 9972:2015 - Thermal Performance of Buildings – Determination of Air Permeability of Buildings – (Single or Single & Multi) Fan Pressurization Method.

What does the Scheme Involve?
Under the scheme, NSAI inspectors assess the operations and procedures of air tightness testers. NSAI inspectors witness an airtightness test against the requirements of I.S. EN ISO 9972:2015.
Inspectors also carry out an assessment of:
- A number of Airtightness test reports.
- That appropriate records are maintained for completed tests.
- Test equipment is adequately maintained and under calibration.
- Health & Safety documentation is in place.
When our inspectors are satisfied that the tester is in compliance with the scheme requirements, the applicant company receives an NSAI Certificate of Registration.
What are the Benefits?
For air tightness testers, the benefits of I.S. EN ISO 9972:2015 registration are far-reaching.
The scheme:
- Helps developers and householders demonstrate compliance with the higher levels of energy conservation required under the Building Regulations 2011 Part L Technical Guidance Document
- Entitles the air testing company to use its NSAI registration number in business transactions
- Lists the company on the NSAI-maintained Directory of Registered Air Tightness Testers
- Provides independent reassurance to customers of the reliability of the air testing company.

What is the Registration Process?
- The registration process is straightforward and involves the following steps:
- The company submits its application for Single or Single and Multi Fan registration
- NSAI requests a pre-audit submission for review
- NSAI contacts the company to arrange an audit date
- Following the audit, NSAI issues a report to the company and agrees what further steps are required to achieve compliance.
After making the required adjustments, the company is registered.
The company can now use its official NSAI registration number on air test reports and Building Energy Rating (BER) Certificates for Buildings.
To maintain registration, the company will undergo regular surveillance audits.
