United Insurance Brokers Ltd (UIBL) has moved its London headquarters to The Leadenhall Building, bringing to an end a 30-year tenure on Mansell Street as the firm aligns its office footprint with broader goals.
The broker, which is part of the United Insurance Brokers Group, is one of the largest independent Lloyd’s brokers by revenue. It places complex and high-value risks across sectors including aviation, marine, energy, construction, cyber and political violence. UIBL serves clients in more than 85 countries and operates a network of affiliated offices across EMEA, the Americas and Asia.
The firm’s new base in The Leadenhall Building, also known as the “Cheesegrater,” places it in the centre of London’s insurance district, alongside major insurers, reinsurers and intermediaries.
The 225-metre skyscraper, designed by Rogers Stirk Harbour + Partners and completed in 2014, is known for its distinctive tapering profile and its focus on environmental performance.
The building holds a BREEAM Excellent rating and uses 100% renewable electricity. It is equipped with waste management systems designed to reduce landfill use and offers access to multiple public transport links including Bank, Liverpool Street and Fenchurch Street stations.
UIBL said the move supports its environmental, social and governance (ESG) objectives and reflects a wider effort to reduce its carbon footprint and modernise its operations. The firm added that the relocation is intended to enhance collaboration and internal communication, as well as provide a workspace aligned with the needs of its staff.
Chief executive Shaun Barrington described the move as a milestone for the organisation and said the new environment supports the firm’s ambitions for innovation and client service.
The relocation comes as UIBL faces an ongoing legal matter involving the UK Serious Fraud Office. In April 2025, the SFO charged the company under Section 7 of the Bribery Act 2010 with failing to prevent bribery by third-party intermediaries in relation to reinsurance contracts placed for a client in Ecuador between 2013 and 2016.
According to the SFO, UIBL received around US$6.2 million in commission, with approximately half allegedly directed to intermediaries accused of making corrupt payments. No current or former individuals at UIBL have been charged. The company is due to appear at Westminster Magistrates' Court.
