Winterflood Business Services

What Winterflood Business Services does

Winterflood Business Services (legal entity WBS Solutions Limited) is a UK-based B2B wealthtech company founded in 2010, headquartered at 138 Cheapside, London, and authorised and regulated by the Financial Conduct Authority. The company operates the proprietary EOS technology platform, which provides institutional execution, custody, settlement, and wealth-management infrastructure to a client base of 63+ institutional investors, wealth managers, digital wealth platforms, discretionary fund managers, corporates, and trustees. Named clients include Transact, Vanguard, Fidelity, Aviva, Quilter, Benchmark Capital, Fundment, and Wealthtime. The platform administers £26 billion in assets, processes £45 billion in traded value and 16 million orders per calendar year, and connects to 38+ global exchanges at 98% straight-through processing and 99.99% system uptime.

The product suite is organised into six core service lines: Institutional Dealing Only (electronic trading across equities, fixed income, ETFs, investment trusts, and structured products); Institutional Dealing & Custody (asset servicing under WBS's own custodian permissions, including fractional ETF trading); Segregated Institutional (retail-level dealing and custody with client money segregation for digital wealth and DFMs); Wealth Platform (end-to-end access for administrators, advisers, charities, and retail investors with portfolio modelling and dual authorisation); Corporate & Trustee Markets (bespoke trading and custody for share plans and trustees); and WBS International (offshore execution via a wholly-owned subsidiary). The Winterflood WRAP retail access platform extends the franchise into retail share offers for AIM-listed companies. Revenue is generated through a mix of recurring subscription/asset-based custody fees and transaction-based dealing fees, with bespoke B2B pricing that is not publicly disclosed.

In December 2025 Marex Group plc acquired Winterflood Securities and divested WBS to Epiris Fund III, completing the PE buyout in June 2026. Under new ownership, CEO Alex Kerry continues to lead the business alongside a restructured board including chairman Chris Woodhouse and NED Andrew Baddeley (both ex-Evelyn Partners). A strategic partnership with JTC Group announced in January 2026 targets geographic expansion into the Channel Islands and adjacent offshore wealth markets.
