Mansion House

Mansion House is the official residence of the Lord Mayor of the City of London, located in the heart of the Square Mile opposite the Bank of England and the Royal Exchange. Built in the Palladian style between 1739 and 1752, it serves as both a working residence and a major venue for high-profile financial, economic and policy events. Annual addresses by the Chancellor of the Exchequer and the Governor of the Bank of England at Mansion House are among the most closely watched set-piece speeches in UK financial policy.

On 20 May 2026, TenU (the consortium of Imperial College, Cambridge, Oxford, UCL, Manchester and Edinburgh) launched the University Spinout Investment Terms for Software Guide at Mansion House, with DSIT Minister Andrew Griffith in attendance . The choice of Mansion House for the launch was deliberate: it signals that university spinout reform is a financial-markets-calibre policy issue, not merely an academic IP housekeeping matter, and positions the USIT framework as a market standard rather than a voluntary guide.

Mansion House's dual role as residence and policy venue gives it a distinctive place in UK economic governance. Speeches delivered there carry institutional weight because they combine the authority of the Lord Mayor's office with the financial audience that attends such events. For the TenU USIT launch, the venue selection amplifies the founder-friendly framing by placing it in front of the investment community that the framework is designed to attract.
