What Clean Slate does

Clean Slate (UK) Ltd is a privately held commercial cleaning company founded in 1983, headquartered in Derby, United Kingdom. It provides recurring B2B cleaning services to offices, CQC-compliant healthcare facilities, schools, factories, and warehouses across the East Midlands, West Midlands, Cambridgeshire, Warwickshire, Staffordshire, South Yorkshire, Derbyshire, Nottinghamshire, and Leicestershire, via a headquarters office in Derby and regional offices in Nuneaton and Cambridge. The customer base exceeds 240 organizations and includes Bosch, Porterbrook Leasing, T Clarke, Rodgers-Leask, Gateway College Leicester, and Victoria Park Health Centre. The company states £6M in annual revenue and 350+ employees, with no external institutional investment, no parent company, and no subsidiaries disclosed.

The operating model is services-led rather than technology-led. Service delivery centers on dedicated cleaning teams with a minimum commitment of 1 hour per day, 5 days per week. Internal technology consists of an automated management scheduling system, an automatic supply replenishment system, and paperless site audits and team inductions; there is no disclosed AI/ML, no mobile app, no public API or SDK, and no proprietary software product sold externally. Differentiation is commercial rather than technical — a "Triple Guarantee" offering noticeably better cleaning, no long-term contracts, and guaranteed reliability, backed by a 500% refund promise, supported by Fair Pay practices (Real Living Wage from day one and a median gender pay gap of 2.0% vs. UK average 14.9%). Sustainability commitments include a 41.7% electric fleet (exceeding a stated 37% 2026 target) and a planned 2026 B Corp certification.

Revenue is generated primarily through monthly recurring commercial cleaning contracts, with pricing determined post-site-audit on a quote basis. The go-to-market combines field sales (sales directors and Business Development Managers pursuing tenders and direct outreach across enterprise, mid-market, and SMB) with inside sales (phone and contact-form-driven quote requests). Customer acquisition is reinforced by client referrals and named case studies. Geographic reach covers nine UK regions but is operationally regional rather than national.
