What is being bought
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.

Procedure rationaleProvision of a curated, research‑ready national dataset of dwelling airtightness/air‑pressure test results for Great Britain’s housing stock, including metadata and documentation sufficient for policy modelling and publication of aggregate statistics. Justification under Procurement Act 2023, s.41 (Direct award in special cases) and Schedule 5 justification (only a particular supplier can supply due to absence of competition for technical reasons and/or exclusive/proprietary rights; no reasonable alternatives).
