## Summary

The public procurement process led by the Regional Business Services Organisation, Procurement and Logistics Service, pertains to the maintenance of boilers, plant, and controls, including boiler water treatment and plate heat exchangers. This contract, under the 'services' category, is not a joint procurement, but is managed by a central purchasing body. This particular procurement process, conducted under an open procedure, has reached the award stage. The evaluation of tenders was primarily based on price (90%) and social value considerations (10%). The contract officially commenced on 17th June 2025, following the tender updates from October 2024 and extends the work within regions associated with the postal code BT12 6HU, UK.

This contract presents lucrative opportunities for service providers specialising in repair and maintenance services, especially those experienced in handling boiler systems. SMEs, particularly those offering innovative solutions in social value enhancements, can find the scope for substantial growth. With specific lots having active awards, namely for 'Low Temperature Hot Water Boilers' with ATS Gas Services Limited, 'Biomass Boilers' with Alternative Heat Ltd, and 'Boiler Water Treatment' with Thermal Impact Group Ltd, businesses engaged in energy management and efficiency services can benefit from this procurement process. Active participation could lead to increased market exposure and potential long-term collaborations within the UK's public sector.
