Clothworkers' Company

The Clothworkers' Company was established in 1528 as one of the City of London livery companies. Mary Ann Slim holds the role of Master for 2025-26. Jocelyn Stuart-Grumbar acts as Clerk. The entity traces its origins to the historic textile trade guilds without a single modern family wealth source disclosed. Capital deployment occurs through direct ownership of commercial real estate in central London. Confirmed holdings include 50 Fenchurch Street, 1 Angel Court, 120 Fenchurch Street, Fountain House, 2 Copthall Avenue, and 8-10 Moorgate. The firm also maintains the West End Freehold Property. Geographic focus remains limited to the United Kingdom. Asset classes center on mixed-use and office buildings alongside collections of silver, tapestries, portraits, and designer bookbindings. Strategy listings repeat fund-of-funds references without named external fund commitments. The team includes Hamesh Patel as Director of Finance, Property and Investments. No professional headcount is published. The Clothworkers' Foundation receives support from the company's assets. A long-standing partnership exists with the University of Leeds through the Leeds Institute of Textiles and Colour. Membership in the Great Twelve Livery Companies and UKFT provides industry network access. No operational events from the last 24 months appear in available records. The livery company structure separates governance through an annually rotating Master from permanent operational roles held by the Clerk and finance director. This creates a succession model tied to City of London traditions rather than family-line control.
