About the buyer

Clarion Housing Group is a housing association that runs its own procurement team for goods, works and services across England. Tenders are advertised through the Delta eSourcing portal, where suppliers register free to bid. Several Dynamic Purchasing Systems cover areas such as asset management, building safety, cladding replacement and general building works. Suppliers are assessed through Achilles Information Limited, with Silver+ Achilles Network status encouraged though not required. Social value and environmental impact are weighted criteria in major procurements. Dedicated working groups coordinate delivery with key contractors including Engie, United Living and Wates.

£434bn was the total UK public sector procurement spend in FY 2025/26.

Over the past 5 years, most of Clarion Housing Group's contract awards have been in business services, architectural and engineering services and financial and insurance services.
