Clean Green

What Clean Green does

Clean Green Services Ltd is a UK-based commercial cleaning contractor founded in 1992 by Susan and Harry Dixon, headquartered in Hadleigh, Essex. The company delivers contract cleaning, deep cleaning, window cleaning, school cleaning, office cleaning, bulk removal, graffiti removal, grounds maintenance, void cleaning, and specialist COVID-19 cleaning services across London (North and South), Essex, Hertfordshire, the South East, Nottinghamshire, the Midlands, and Bedfordshire. Its service portfolio targets three primary verticals — social housing (notably PA Housing across 200+ sites), education (St Mary's of Prittlewell), and commercial offices (Spoilt4Choice, CCTV, BAM Facilities Management) — with additional activity in food and beverage, manufacturing, and local government.

The company's core technology and process differentiation centres on environmentally friendly cleaning methodologies, supported by ISO 9001, ISO 14001, CHAS, Constructionline, BICS, and UK Environment Agency registrations. It does not operate software, APIs, or proprietary platforms; service delivery relies on trained staff operating under dedicated area managers and contract supervisors with embedded monitoring systems. ESG positioning is reinforced through the Oceans Together Forum partnership and long-running international social impact initiatives in Kenya (a school in Malindi and an orphanage in Nairobi since 2000).

Commercially, the business operates a managed-services revenue model under bespoke multi-year contracts. Pricing is quote-based rather than tiered, with contracts won through tender processes and direct sales supported by website quote forms, a dedicated sales contact, and published case studies. Revenue is not publicly disclosed; no external funding, institutional investment, or M&A activity has been recorded. The founder family remains actively involved in ownership, with Michael Dixon as Director of Operations and Susan and Harry Dixon continuing to drive the social impact programme.
