Summary of the contracting process

Southern Housing procured external and internal window-cleaning services for high-rise housing, including buildings up to and over 75 feet. The requirement sits within a dynamic purchasing system for cleaning services and is classified as cleaning and sanitation services (CPV 90900000). The work is delivered in London for Southern Housing, the buying organisation. The scope is focused on window cleaning rather than general cleaning: suppliers are expected to clean external windows across different building heights and internal windows in high-rise properties. The opportunity is categorised as a service and was identified as suitable for small and medium-sized enterprises and voluntary, community and social enterprise organisations.

This procurement has been awarded and is complete. Southern Housing used a selective restricted procedure within its dynamic purchasing system. The tender deadline was 20 May 2026. Four Corners Cleaners Ltd was awarded the contract on 20 May 2026 for £466,688.64 including the stated GBP currency. The contract period runs from 6 July 2026 to 5 July 2034. The awarded requirement covers the London window-cleaning service described above. The award is active, and the selected supplier is identified as a small and medium-sized enterprise. The process therefore demonstrates an eight-year requirement being placed through a restricted route rather than an open tender.

For competitors, this award provides a clear indication that Southern Housing buys specialist window-cleaning capacity for high-rise residential properties at substantial scale and through a dynamic purchasing system using a restricted procedure. A credible supplier would need to deliver both external and internal window cleaning, including work on buildings above 75 feet, with the equipment, trained staff, access arrangements and health and safety controls required for high-rise operations. Experience managing scheduled cleaning across housing properties would strengthen a future offer, alongside the capacity to cover London locations reliably. The requirement was suitable for SMEs and VCSEs, showing that smaller specialist cleaning businesses can be relevant where they can demonstrate operational resilience, compliance and suitable high-level access capability.
