## Summary

The London Borough of Hillingdon has completed the tendering process for a Multi-Lot Window and Door Replacement Programme. This procurement sought to onboard multiple contractors to deliver works across the North, Central, and South areas of the Hillingdon Borough, with the aim to implement the replacement programme from 2025/26 onward. The process followed an Open procedure with a planned contract form of JCT MTC. Key dates included the award date of 26th February 2026, with contracts starting from 13th April 2026 and potentially extending until 12th April 2031. The main procurement category was works, specifically the installation of doors and windows, highlighted under the CPV code 45421130. This initiative by the London Borough of Hillingdon represents a significant investment in infrastructure, with several contracts awarded amounting to gross values in the millions of GBP.

This opportunity opens a substantial avenue for business growth, particularly for businesses specialising in construction, glazing, and related sectors. The project's division into multiple lots allows a range of businesses, from large suppliers like Evander Glazing and Locks Limited and Sovereign Group Limited to SMEs such as Sovereign Group Limited in the South area, to engage at different levels, depending on their capacity and expertise. Such contracts are ideal for firms that can deliver high-quality installations while maintaining good customer relationships and meeting the Council's performance requirements. Companies fulfilling these contracts may enjoy steady work over the contract's lifespan, with the potential for extensions, ensuring continuity and stability in business operations.
