## Summary

The Scottish Prison Service, located in Edinburgh, UK, has undertaken the procurement process for the SPS-11003 HMP Perth Boiler Upgrade as a public order and safety project. This work involves the design and installation of four replacement 1200kW dual fuel boilers at the Main Energy Centre at HMP Perth, including associated systems and a 24m high chimney stack. The procurement process, managed under an 'open procedure' method, commenced with planning in October 2025, proceeded through tendering in November 2025, and has now reached the award stage with the contract being signed with James Ramsay (Glasgow) Ltd. The procurement stage is complete, with a contract value of £1,183,607.41 GBP, signed on 19th February 2026.

This tender offers significant growth opportunities for businesses specialising in industrial heating systems and infrastructure projects, particularly those able to deliver complex installations and manage large-scale construction operations. The project favours businesses with expertise in energy-efficient technologies and integrated safety systems. Small to medium enterprises (SMEs) in the UK, with prior experience in similar public sector contracts, stand to benefit greatly from competing for such opportunities, leveraging their agility and innovation in delivering specialised solutions within budget constraints.
