The project, located in the Leeds AZP Area, involves creating a large-scale, low carbon heat network. It is overseen through a Golden Share Development Agreement, forming a strategic partnership for the Advanced Zoning Programme. The procurement process, conducted using a competitive flexible procedure method, has reached the award stage, where Hemiko Limited will undertake the construction and operation of the network. This ambitious urban development and heating works project, classified under CPV codes for energy services and district-heating mains construction, is scheduled to start by 27th March 2026 and will continue through 31st March 2076. The contract's value is substantial, with gross amounts reaching £4.086 billion, offering significant opportunities in public works.

This tender represents significant business growth opportunities, particularly for companies skilled in energy services and urban development construction work. With Leeds City Council possessing a Golden Share providing strategic influence in the partnership, businesses with expertise in sustainable infrastructure and low-carbon technologies stand to benefit from this long-term, lucrative project. The opportunity is especially suited for businesses capable of meeting technical, commercial, and social value criteria. Large-scale enterprises, and potentially SMEs with proven experience in district-heating systems, can leverage their capabilities to not only participate but thrive in this expansive venture that aims at reducing carbon emissions in urban developments while creating sustainable energy solutions. This contract also underscores the future introduction of Heat Network Zoning regulations, positioning forward-thinking companies at the forefront of the energy sector in the UK.

The Development & Funding Partner will be responsible for further development activities, funding and delivering the Project under the SHA, as the Development & Funding Partner. LCC will hold a Golden Share under the SHA. LCC (in its own right and via its wholly owned subsidiary) is the owner and operator of the Leeds PIPES heat network ("Leeds PIPES").

Stage 1: Conditions of Participation - issuing this Tender notice and a Procurement Specific Questionnaire, which includes the Conditions of Participation. b. Stage 2: Interim Tender Response Phase - suppliers who have been successfully shortlisted at Stage 1 will be invited to submit an Interim Tender Response. This will be limited to a legal response on the Contract Documents. c. Stage 3: Dialogue Meetings - Following receipt of the Interim Tender Responses, dialogue meeting(s) will be held with each Supplier to discuss their responses in Stage 2. d. Stage 4: Invitation to Submit a Final Tender Response - Stage 4 will commence with LCC providing any documents which have been updated following Stage 3, and inviting suppliers to respond to the Technical, Commercial and Social Value questions. e. Stage 5: Preferred Supplier Stage - LCC will provide an assessment summary to all Suppliers that submitted Final Tender Responses. LCC will clarify commitments with the Supplier who LCC considers has the Most Advantageous Tender in order to finalise the Contractual Documentation. During this stage LCC will not negotiate substantive terms post final tender evaluation and award, only using this stage to clarify and confirm commitments made in the tender negotiation. This will ensure a confirmed understanding of how the contract will operate and reducing the risk of issues arising once the contract has been entered into. The conditions of participation used in Stage 1 will include: * Financial Capacity * Insurance * Data Protection * Legal Capacity * Technical Ability (relevant experience and case study examples) * Health and Safety * Requirement under section 73 of the Act * Tackling Modern Slavery in Supply Chains"
