Interested parties must submit tenders electronically by 13 March 2024, with Mott MacDonald Limited identified as the winning supplier as of 12 March 2026, alongside subcontractors enhancing service delivery.

This tender heralds substantial business opportunities, particularly for organisations specialising in low-carbon consultancy services. The framework agreement is designed to provide wide-ranging consultancy, from technical support to strategic planning, and encourages participation from small to medium enterprises (SMEs) and a consortium of suppliers, thereby offering a platform to expand business within the public sector. Businesses adept in areas such as solar energy, local energy planning, and low carbon heating can leverage this contract to foster growth and collaboration with the GLA and its associated bodies. The procurement method embodies the Most Economically Advantageous Tender, emphasizing the high-quality, social value, and commercial benefits, inviting capable businesses to contribute to London’s carbon reduction goals by 2030.
