CSS Commercial Cleaning is a professional cleaning company headquartered in Farnborough, Hampshire, serving clients across Greater London, the South East, South West, Essex, and Kent. The company delivers a broad range of specialist cleaning services tailored to commercial, industrial, and domestic environments — including office cleaning, retail and commercial premises, industrial and warehouse facilities, schools, medical and hospital settings, leisure and hospitality venues, and domestic properties. We also offer window cleaning, PAT testing, and COVID-19 decontamination services.
A key differentiator for CSS Commercial Cleaning is our commitment to sustainability through a dedicated "Green Clean" package, which uses eco-friendly, toxin-free products that are safe for people and pets while reducing environmental impact through lower water pollution, fewer toxic chemicals, and reduced packaging waste.
CSS Commercial Cleaning prides itself on employing fully vetted, DBS-checked staff and operates with transparent, upfront pricing — with no hidden costs agreed before work begins. Flexible scheduling options (daily, weekly, or fully bespoke) help minimise disruption to clients' operations. They use professional-grade equipment and conduct regular quality checks to ensure consistently high standards. CSS Commercial Cleaning also provides NHS services and holds accreditations from recognised bodies including BICSC. Free, no-obligation quotes are available on request.
