1. Reuben Brothers

The Geneva-based family office of David and Simon Reuben completed 5-6 major transactions in 2025, making it the UK’s most active by deal count. With an estimated £24.9 billion family fortune, the brothers deployed capital across hospitality real estate, sports equity and early-stage investments. In September 2025 they injected £111.5 million into Newcastle United FC, increasing their stake from 10 % to 15 % via RB Sports & Media – their largest single capital commitment since the 2021 takeover consortium. In August, their aerospace investment Firefly Aerospace went public. Real estate remained central: the £1 billion Piccadilly Estate redevelopment of Cambridge House into a luxury hotel and members’ club reached completion in late 2025. The October 2024 acquisition of W South Beach Miami for US$425 million (South Florida’s largest hospitality deal that year) began full operations under Reuben ownership in 2025. Planning approval for the Pilgrim Place office development in Newcastle (January 2025) added another UK pipeline project. The family office also explored a nine-figure investment to join a consortium bidding US$7 billion for OnlyFans (unconfirmed).

The Logothetis family’s international holding company completed two major 2025 transactions through operating subsidiaries, demonstrating a continued commitment to renewable energy and advanced mobility. Though technically structured as a family holding company with 20 operating businesses across 60 countries, Libra functions as both operating-group and strategic investment vehicle. In September 2025, subsidiary Greenwood Sustainable Infrastructure acquired the 556 MWdc Homestead Solar Project in Alberta, Canada – the country’s second-largest solar development – boosting its pipeline to 2.1 GWdc. In July 2025, Libra’s airline-leasing arm placed a purchase order for 25 all-electric aircraft (BETA Technologies ALIA CTOL) via Space Leasing International, marking entry into advanced air mobility.

Highlight investments in 2025 include a £260m Wimbledon mixed-use development with Re:Shape living, where Topland provides a £17M senior debt facility, or the completion of ESG-led development of Verdant at 150 Aldersgate, a BREAAM Excellent-certified office development.

5. Tavistock Group

The Bahamas-based investment organisation of Joe Lewis completed two major 2025 transactions – including one of the year’s largest UK sports investments.  In October 2025, ENIC – a majority-owned subsidiary-  injected £100 million (~US$133 million) into the Tottenham football club to support squad development and competitive positioning in the Premier League and Europe. In September 2025 the 28-unit Indigo Tower at the Pier Sixty-Six development in Fort Lauderdale reached completion, marking a milestone in Tavistock’s Florida real-estate portfolio.

In October 2025, West Coast acquired Port Edgar Holdings, Port Edgar Marina and Production Yachts under a long leasehold extending to 2100 in South Queensferry – a strategic leisure-infrastructure investment. In June 2025, they participated in the management-buyout of Buzzworks Holdings alongside Alchemy Partners and Cynergy Bank financing; though technically a restructuring from majority to minority position, the office retained significant stake in the hospitality group targeting £100 million+ valuation.

7. BNF Capital

The London-based family office of the Perrodo family (managing ~US$20 billion) completed two major 2025 transactions spanning AI enterprise software and prime Manhattan retail real estate. In October 2025 they participated in a US$260 million Series F in enterprise-AI company Uniphore, positioning alongside Nvidia and Snowflake in backing the unicorn.
