## Summary

The Mayor and Commonalty and Citizens of the City of London are planning a major refurbishment of the historic Mansion House, with the project classified under the works category. This procurement, still in the planning phase, involves comprehensive refurbishment tasks including mechanical and electrical upgrades, internal renovations, roof replacement, and façade cleaning. The legal basis for this procurement is the Procurement Act 2023, and the project is subject to specific regulations and legislative compliance.
