The Authority intends to appoint a Contractor to design and build (and to subsequently Operate and Maintain) a low carbon heat network and associated energy centre in the city of Hull. The heat network is intended to be expanded in future Phases. The requirements relate to Phase 1 of the Heat Network and the Energy Centre. Kingston upon Hull City Council is conducting the procurement using the Negotiated Procedure with prior call for competition in accordance with the requirements of Regulation 47 of the Utilities Contracts Regulations 2016 (SI 2016 . 274) ) (UCR 2016). The Authority reserves the right to proceed with the award of the contract following the initial tender submission should it determine, at its sole discretion, that the bids received can be accepted without proceeding with the negotiated stage. It is intended to appoint a principal contractor for these works to start in early 2025, and for Phase 1 of the network fully completed by March 2028.
