Hull City Council is seeking a Design, Build, Operate and Maintain contractor to help deliver the next stage of Hull District Heat Network (HDHN).
The successful tender will deliver Phase 1 of HDHN which will involve providing heat and hot water to more than 40 buildings in Hull city centre.
This will include a variety of council buildings, as well as other public and private sector organisations around the city.
Cllr Charles Quinn, portfolio holder for environment at the council, said: “It is pleasing that Hull District Heat Network has progressed to now be able to appoint a contractor.
“The council remains committed to responding to the climate and nature emergency and Phase 1 of the project will also help the council to achieve its net zero ambitions.”
