## Summary

Westminster City Council has finalised a procurement process titled "PDHU Financial Modelling and OBC Development," focusing on financial and insurance services. Located in London, the council has engaged in a direct procurement method, below the threshold without competition. This process is now in the completion stage, as of 10th September 2025.
