About the buyer

Thirteen Housing Group is a housing association based in the North East, and its procurement team advertises tenders through its own In-tend portal. Above-threshold opportunities also appear on the Government's Find a Tender service and on Contracts Finder. Suppliers register free on In-tend to see live tendering opportunities. Specialist consultancy panels, including principal designers, are sourced through the Procurement Hub dynamic purchasing system. Every above-threshold tender carries a social value expectation, assessed through Thirteen's own Match My Project platform. Suppliers are also expected to complete checks confirming their supply chains are free from modern slavery.

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

Over the past 5 years, most of Thirteen Housing Group Ltd's contract awards have been in construction work, software and information systems and IT services.
