## Summary

Caerphilly County Borough Council is procuring works to renew and install two boilers at The Winding House Museum. The requirement is boiler installation, including associated heating engineering for a building, and covers radiators and boilers where required. The work is to be delivered at The Winding House Museum in Caerphilly County Borough. This is a building-services and mechanical-installation opportunity for contractors able to replace existing heating equipment and complete the associated installation works. The detailed scope is set out in Appendix 1 and the invitation-to-tender documents. The council is the buying organisation and applies Welsh devolved procurement regulations. The procurement is classed as works rather than goods or standalone consultancy services.

The process has reached tender: the council invited offers through a below-threshold open competition. Bids are submitted electronically through the Proactis Supplier Portal, with questions sent through its messaging system. Enquiries close on 2 September 2026 at 23:59, and tenders must be submitted by 9 September 2026 at 12:00. The planned construction start is 28 September 2026, or earlier by agreement. The stated contract period runs from 23 September to 7 October 2026, with the project description indicating a two-week duration. The estimated value is £30,000 excluding VAT, or £36,000 including VAT. There is one lot. The award will be based entirely on total project cost, weighted at 100%.

This opportunity suits small and medium-sized enterprises, particularly mechanical and building-services contractors with practical experience of boiler replacement and heating-system installation. Suppliers should be able to install two boilers in a museum building, work to the technical requirements in the tender documents and complete the works within the stated project window. Relevant capability may include heating engineering, boiler and radiator installation, site coordination and the safe removal or replacement of existing equipment. The requirement is most relevant to firms that can provide a complete installation service rather than suppliers of boilers alone. The evaluation is wholly price-based, so businesses should be able to submit a competitive, fully costed proposal against the pricing schedule. No specific accreditation or named experience requirement is stated.
