The project, titled "Decarbonisation – Royal Armouries Boiler Replacement," falls under the industry categories of district heating and heating equipment. The procurement process is currently in the tender update stage, with inquiries concerning submissions accepted until 9th January 2026 and final submission due by 26th January 2026. The procurement is managed by the museum's Procurement Department, located in Leeds, within the UKE42 region of the United Kingdom. Leveraging a gross budget of £1,080,000, this initiative seeks innovative, carbon-efficient heating technologies, aiming to eliminate the reliance on fossil fuels. This tender presents substantial opportunities for businesses specialising in electric heating systems, such as Air Source Heat Pumps or Ground Source Heat Pumps, or those with alternative innovative solutions. It is particularly advantageous for small and medium enterprises (SMEs) and voluntary, community, and social enterprises (VCSEs), given the nature of the open competition that welcomes diverse and effective proposals. Firms with expertise in engineering design, mechanical and electrical services, and district-heating systems are well-suited to compete, with the potential to contribute significantly to the museum's sustainability efforts while expanding their own credentials and market presence. The award criteria include both cost and quality factors, with an emphasis on pricing, system requirements, and delivery strategy, ensuring a balanced evaluation for all submissions. ## Notice The aim of the project is to replace the existing boilers at the Royal Armouries Museum in Leeds with a more carbon-efficient technology that does not utilise natural gas or any other fossil fuels. While the tender primarily seeks an electric solution, such as Air Source Heat Pumps (ASHP) or Ground Source Heat Pumps (GSHP), other technologies or approaches are also welcome for consideration.
