## Summary

The City of London Corporation has announced an active procurement opportunity for the development of a low carbon heat network in the Square Mile area, focusing on urban development and energy-related services. The procurement process is overseen by The Mayor and Commonalty and Citizens of the City of London, with OVE ARUP & PARTNERS LIMITED, SHARPE PRITCHARD LLP, and LOCAL PARTNERSHIPS LLP providing procurement, legal, and commercial support respectively. The tender is in the "tender" stage, with deadlines for various submissions ranging from 12 January 2026 to 22 June 2026, and the contract is set to be signed by 26 November 2026. This project is poised to impact areas around the City of London, including borders with Westminster, Camden, and Islington, with a total estimated gross value for the deal of £5,210,400,000 GBP under a competitive flexible procedure.

This tender presents substantial opportunities for business growth within the urban development and renewable energy industries, particularly for companies with expertise in district heating and energy services infrastructure. Businesses specialising in construction and heating works are well-suited to compete, thanks to the CPV classification of the procurement items, which include urban development construction and heating works. The robust structure of the tender with its multi-stage competitive procedure allows companies to highlight their technical ability alongside commercial viability and social value contributions. With no capital investment required from the City of London itself, businesses have the opportunity to become instrumental partners in a high-value project with substantial longevity, as the contract period extends to 2068.

## Notice

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.
