Your article entitled "Government attacked over Constructionline" (21 February, page 12) was inaccurate in its use of a quote from Peter Elston's letter to Brian Wilson, which stated that "a number of major [government] clients, including Defence Estates and NHS Estates, were also on the list of non-users".
In fact, both NHS Estates and a large number of defence bodies are among the top users of Constructionline.

The recent requirement by NHS Estates to assess all members of the Procure 21 supply chains to Constructionline standards is an endorsement of the system by central government, and follows the addition of 320 public sector clients to our list in the past year. Just as importantly, there has been a significant improvement in the number of longlists produced in recent months, which indicates that more of our clients are using the system as intended.
