## Summary

The Department for Energy Security & Net Zero has completed a tender process for the "UK Housing Airtightness (Air-Pressure Test) DataSet," awarded to Build Test Solutions. This project falls under the services category, particularly research services, highlighting the need for air pressure test results to validate infiltration methodology for the Home Energy Model. Located in the United Kingdom, the procurement was executed without competition, as a direct award was below the threshold. The contract, valued at £33,000 gross, commenced on 27th February 2026 and is set to conclude on 31st March 2026.

This award presents significant business growth opportunities for large-scale enterprises specialising in research and testing services. With the requirement for approximately 70,000 test results, companies with robust data collection capabilities in the field of energy efficiency would be well-positioned to leverage future opportunities in this sector. The engagement with a central government authority also provides potential exposure and credibility, fostering deeper industry connections and potentially leading to further contracts in energy and housing-related projects.

## Notice

DESNZ requires results from real air pressure tests to validate the proposed infiltration methodology to be used for the Home Energy Model. A test data sample size of approx of 70,000 test results are needed to validate against is the critical requirement. The larger the sample of results, the more reliable the validation of the HEM methodology will be.
