What Thesis Asset Management does
Thesis Asset Management Limited is a UK-based private investment management firm headquartered in Chichester, West Sussex, providing custody, trade execution, and bespoke discretionary portfolio management to UK clients. Founded in 1974 and operating under FCA Registration Number 114354 (company number 01802101), the firm serves high net worth individuals and families (the primary Private Office segment), alongside charities, family offices, and institutional clients. Clients are sourced predominantly through referral relationships with authorised financial advisers, lawyers, accountants, and tax professionals, and the website explicitly disclaims US distribution given the firm is not registered with the SEC.
The product set spans custody and trade execution across equity, bond, and fund instruments; segregated individual investment portfolios; a Private Office service for ultra-high net worth clients providing personalised wealth planning; and a Junior ISA wrapper for tax-advantaged savings on behalf of minors. The operating technology stack is built largely in-house using Oracle PL/SQL, SQL Server T-SQL, Access, Excel, and PowerShell with automated datafeed interfaces over XML, CSV, and FTP, augmented by third-party RPA tools (Xceptor, UiPath, Microsoft Power Automate) for reconciliation and back-office workflows. Investment decisions are made by an experienced in-house committee holding CFA, CISI, and Society of Professional Economists designations, with remuneration structurally decoupled from investment performance to mitigate conflicts.
The revenue model is anchored in recurring investment management fees on assets under management, supplemented by custody fees and transaction-based trade execution charges. Pricing is bespoke and not publicly disclosed, varying with portfolio size and service scope. Distribution is domestic UK-only via a single Chichester office, with no public listing, no disclosed funding rounds, no acquisitions, and no parent company identified — the firm operates as an independent private limited company with an associated group entity, Thesis Services Limited.
