## Summary

The Royal Household in the United Kingdom has completed the procurement process for the RHPS HVAC and BMS Servicing and Maintenance, a services category tender. The project covers sites in London and Windsor, with lots focusing on HVAC and Building Management Systems maintenance. The procurement was conducted using an open, competitive flexible procedure. Key milestones included the completion status date of 4th June 2026, with contract start expected on 1st October 2026, running through 30th September 2029, plus options for two additional one-year extensions. The total contract value is spread over three lots, with Lot 1 awarded to Forth Building Services Ltd for London HVAC services and Lot 2 for Windsor HVAC services, while CBRE Managed Services Ltd secured Lot 3 for BMS maintenance at the Windsor Estate. Contracts are set to follow required standards, including statutory compliance and sustainability metrics.

This contract offers significant business growth opportunities for companies within HVAC and facilities management sectors. Small to medium-sized enterprises (SMEs) with expertise in HVAC systems, and large firms with skills in BMS maintenance, could benefit from participating in such tenders due to sizeable contract values exceeding the threshold. The demand for specialised technical knowledge in maintaining critical heritage and modern systems across high-profile sites like Buckingham Palace and Windsor Estate further underscores the importance of these contracts. Businesses capable of delivering comprehensive service management, energy optimisation, and alignment with stringent compliance requirements could find substantial opportunities in future government tenders.
