UK7 - Contract Details Notice
Summary of the contracting process

Carmarthenshire County Council commissioned a detailed feasibility study into developing a mine water-powered district heating scheme within Carmarthenshire. The work covers district heating and related research and development consultancy services, with delivery in the county. The requirement is intended to assess the potential development of a local heat network using mine water, rather than to procure construction or operation of the scheme itself. The council is the public-sector buyer. The appointed provider is Sustainable Energy Ltd, a Cardiff-based small and medium-sized enterprise specialising in sustainable energy consultancy. This opportunity is therefore relevant to firms with experience in energy feasibility studies, district heating, mine water or other low-carbon heat sources, and public-sector energy strategy.

The procurement is complete and has been awarded following a below-threshold limited competition. It comprised one lot. Carmarthenshire County Council awarded the contract to Sustainable Energy Ltd on 20 July 2026. The contract runs from 27 July 2026 to 30 November 2026, with a maximum possible extension to 31 March 2027. Its value is £49,860 excluding VAT and £59,832 including VAT. The contract is active and includes an optional Phase 2, dependent on approval and the outcomes of Phase 1. The selected supplier is undertaking the feasibility study and associated consultancy services for the council’s mine water heating and district heating plans.

This award demonstrates a defined requirement from Carmarthenshire County Council for specialist low-carbon heat feasibility work, combining district heating analysis with investigation of mine water as an energy source. Suppliers seeking to compete for comparable future requirements from this buyer would need credible capability in heat-network development, renewable or recovered heat, energy modelling, technical feasibility assessment and research-led consultancy. Experience of translating technical findings into a practical public-sector scheme would also be relevant, particularly where an initial study may lead to a further delivery phase. The appointed supplier is an SME, indicating that a focused specialist consultancy can meet this type of requirement without the scale of a major infrastructure contractor.
