## Summary

The Royal Armouries Museum in Leeds initiated a procurement process titled "Decarbonisation - Boiler Replacement," focusing on replacing existing boilers with carbon-efficient technology. The project falls under the works industry category, with key activities based within the region of UKE42, United Kingdom. Initially slated to progress through various stages, the tender process was canceled on 19th August 2025. The procurement method was an open competition, below threshold, with deadlines for the tender period originally set on 4th September 2025 and the enquiry period ending on 21st August 2025.

This procurement presented opportunities for SMEs and VCSEs to engage in the public works sector, providing essential upgrades to the Royal Armouries' heating infrastructure. Businesses specialising in district heating, long-distance heating, and low-carbon technology solutions would have benefited by participating, enabling them to showcase expertise in sustainability and innovative engineering. Though the tender has been canceled, such commitments towards decarbonisation projects highlight opportunities for similar future schemes that businesses could explore for growth and visibility in public sector collaborations.
