What is being bought
City of London Corporation (“CoLC”) is seeking via this Procurement to select a Heat Network Development Partner to develop the Network and, subject to receipt of the necessary approvals, deliver the Network. It is intended that, as a result of this Procurement, CoLC will enter into a development agreement under which the Heat Network Development Partner (via the special purpose vehicle (the “SPV”) established for development and delivery of the Network) is required to design and develop the Network up until the point at which it is ready to be built, at which point, it will present the project for approval by CoLC. Provided that the project passes this “Approvals Gateway”, CoLC and the Heat Network Development Partner will be required to enter into the Shareholders’ Agreement which will govern the management of the SPV and impose obligations on delivery and operation of the Network. CoLC invests no capital in the SPV and derives no economic benefit as a Shareholder but, holds a “special” or “golden” share in the SPV which allows it certain rights as set out in more detail in the Contractual Documentation. The geographical area for the development and delivery of the Network is bounded by: a) the City of London boundary with Westminster, Camden, and Islington; b) roads including Moorgate, Princes Street, King William Street, and London Bridge; and c) the River Thames. The indicative procurement dates for this opportunity are: 12/01/2026 - Deadline for initial clarification questions submitted (Enquiry Deadline) 26/01/2026 - Deadline for receipt of PSQ Response (Tender Submission Deadline) 23/03/2026 - Deadline for receipt of Interim Tender Responses 22/06/2026 - Deadline for receipt of Final Tender Responses 05/11/2026 - Assessment summaries & Contract Award Notice issued 26/11/2026 - Contract signature (Contract Start Date)
