What UK Andersen does
UK Andersen is the United Kingdom member firm of Andersen Global, a Swiss verein of legally separate, independent member and collaborating firms that deliver tax, valuation, financial advisory, and global mobility services. The broader Andersen organization was founded in 2002 by 23 former Arthur Andersen partners as Wealth & Tax Advisory Services (WTAS), acquired the Andersen brand in 2014, and rebranded to simply Andersen in 2019. Andersen Global reports 16,000+ professionals, 2,000 Global Partners, and presence across more than 170 countries through 450+ locations. Andersen Group Inc., the affiliated parent entity, completed its IPO on the New York Stock Exchange in December 2025 under ticker ANDG, while member firms such as UK Andersen remain partner-owned.
The firm's service portfolio is organized into Tax (compliance, international tax, state and local, controversy, credits and incentives, global mobility, tax transformation), Transaction Advisory (M&A buy-side and sell-side, financial and tax due diligence, fund formation, real estate advisory), Valuation (tax planning, wealth transfer, financial reporting, asset valuations, litigation support), Private and Outsourced Accounting (financial statement administration, bill pay, cash and asset management), and Private Wealth (family office, investment consulting, forensic accounting, international wealth planning). No proprietary technology platform is disclosed; delivery rests on senior professional talent and the global Andersen network. Marketing and client development rely on content (resource articles, CFO Series, For the Record newsletter), webinars, and Managing Director speaking engagements at industry conferences such as IFA USA, NYU Summer Institute, IRS Nationwide Tax Forum, and the Jerry A. Kasner Estate Planning Symposium.
UK Andersen monetizes through customized, quote-based professional services fees, delivered directly by Managing Directors who work directly with clients on tax, valuation, and transaction advisory engagements. The target market is diversified by design, spanning family offices, entrepreneurs and founders, corporate executives, alternative investment funds (private equity, venture capital, hedge funds, real estate, fund of funds, distressed assets), middle market businesses, and large companies with cross-border needs. Go-to-market is sales-led and relationship-driven, leveraging partner-level client coverage rather than volume-based distribution channels. Andersen Consulting, launched February 2025, extends the addressable market into digital transformation, AI, and cybersecurity advisory, but operates as a distinct practice layered on top of the tax-and-valuation core.
