Sumillion Limited

Best Circular IT & Sustainable Technology Services - Hampshire, 2026

Sumillion is a UK‑based IT solutions provider that has built its reputation by embedding sustainability into the core of its business model. Founded in 2012 and headquartered in Basingstoke, the company supports organisations across procurement, infrastructure, cloud, and managed services, while reducing environmental impact through circular IT practices and carbon‑tracked delivery.

For our clients, the priority is clear: structured carbon reporting, lifecycle visibility, and the ability to make informed procurement decisions that stand up to audit and scrutiny. Sumillion’s Green Partnership focuses on delivering these practical changes, helping organisations reduce impact through better buying, longer asset life, and accountable IT strategy, while supporting social programmes, including clean water and education work in Ghana and counselling services in Hampshire.

This year Sumillion received the King’s Award for Enterprise in Sustainability, recognising an approach where sustainability is treated as a core business risk and decision point, not a separate initiative.
