Summary of the contracting process

Leeds City Council procured the Leeds City Centre Heat Network, extending heat network infrastructure to Leeds South. The requirement is a major works and energy project covering urban development construction, district-heating mains, heating works, and related energy services. The work is to be delivered in Leeds. The council is the buyer, with Ove Arup and Partners providing procurement support and advice, Addleshaw Goddard providing legal support, Hermetica Black acting as technical adviser, and Asteros Advisers providing commercial support. The requirement is structured as a concession and concerns the development and operation of heat network infrastructure rather than a routine supply contract. It is a single-lot opportunity, awarded to Hemiko Limited, a Carlisle-based small and medium-sized enterprise.

The procurement has been completed and awarded following an open competitive flexible procedure. The process used five stages: conditions of participation, an interim legal tender response, dialogue meetings, final tender responses covering technical, commercial and social value matters, and preferred-supplier clarification. The tender deadline was 17 October 2025 at 11:00, with enquiries closing on 29 July 2025 at 11:00. The award decision period ended on 13 February 2026. Hemiko Limited was awarded the single lot, and the contract was signed on 5 August 2026. The contract runs from 5 August 2026 to 4 August 2076. Its value is £3,405,000,000 excluding VAT, or £4,086,000,000 including VAT. Evaluation weighted technical quality at 75%, commercial factors at 15% and social value at 10%.

This procurement demonstrates substantial, long-term demand for suppliers able to deliver and operate district-heating infrastructure at city scale. A credible future competitor would need strong technical capability in heat network design, construction of district-heating mains and heating systems, urban development works, and associated energy services. Relevant experience and case studies were required, alongside financial capacity, appropriate insurance, legal capacity, data protection capability, health and safety arrangements, and compliance with modern slavery supply-chain requirements. Suppliers also needed to address social value commitments and targets. The multi-stage route shows that future participants should be prepared for legal review, structured dialogue, detailed technical and commercial submissions, and clear evidence of the ability to manage a complex concession over an extended operating period.
