# Where does a cleaning company find public tenders?

Cleaning contracts run under CPV division 90, sewage, refuse, cleaning and environmental services. Schools, hospitals, councils and courts buy them on recurring cycles, which makes the renewal calendar the real opportunity. In the measured Portuguese register, division 90 carried 776 opening announcements in 2026 with 1,035 distinct winning companies in the year: many small, frequent contracts rather than a few large ones.
