Supply and Demand Modelling - Property Strategy

About the buyer

House of Commons is the elected chamber of the UK Parliament, procuring through the Parliamentary Commercial Department, a shared service for both Houses. Suppliers log into the Atamis portal to see openly advertised tenders. Larger contracts also appear on the Central Digital Platform through the Find a Tender Service. Smaller or less open competitions run through framework agreements, some set up by the department and some by bodies such as the Crown Commercial Service. Upcoming larger procurements are flagged through individual pipeline notices. Purchase orders carry UK Parliament's own standard terms unless different terms have been agreed.

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

Over the past 5 years, most of House of Commons's contract awards have been in business services, IT services and architectural and engineering services.
