## Summary

North Lincolnshire Council, a sub-central government authority in the United Kingdom, recently completed a tender process for a window replacement scheme at Sir John Nelthorpe School. The procurement was executed through a direct method below the threshold without competition. Situated in Scunthorpe, this project is within the UKE13 region, and the main focus was on works and goods within the construction industry. The award was finalised on the 13th of November 2025, and the project is scheduled to commence immediately, concluding by the 31st of August 2026. The contract, valued at £49,914, was awarded to Mason Clark Associates Limited, headquartered in Hull.

Such contracts not only provide a steady revenue stream but also enhance the awarded firm's industry reputation and position them advantageously for future government projects.
