On 17 October 2025, the Chancellor of the Exchequer announced the fully operational Office for Investment: Financial Services.

This will be a free support service available to global financial services firms, helping firms to pick locations, navigate regulation and Britain’s business environment. It will be delivered by the Office for Investment in partnership with HM Treasury, financial regulators and the City of London Corporation and is intended to deliver on commitments made in the Chancellor’s Mansion House speech to reduce regulatory uncertainty and make the UK more attractive to investors.
