What Blick Rothenberg does

Blick Rothenberg is a London-headquartered tax, accounting, and business advisory firm founded in 1945 by Helmut Rothenberg OBE. The firm serves four primary client segments: high-net-worth individuals and private clients (inheritance tax, trusts, non-dom/US-UK cross-border planning), entrepreneurs and owner-managed businesses (corporate tax, transaction services, R&D tax credits, audit), financial services firms (hedge fund and private equity managers, wealth managers — acting for 180+ FCA-authorised firms), and international groups with UK operations. Specialist services include Tax Advisory, Audit Accounting & Outsourcing, Global Mobility Services, Private Client Services, International Services, Outsourced Business Services, Transaction Services for M&A, and US/UK Private Client dual-qualified advisory.

The firm operates through a partner-led delivery model from a single headquarter office at 16 Great Queen Street, Covent Garden, with 700+ professionals including 70+ partners and directors. International reach is delivered indirectly through membership in Allinial Global (260+ member firms across 100+ countries), rather than via owned international offices. Supporting infrastructure is conventional for the sector: a CoZone client portal, basic tax calculator and calendar digital tools, plus thought-leadership content via The Tax Factor and BRave Business podcasts. No proprietary technology platform, AI/ML products, or APIs are disclosed.

Revenue is generated through professional services fees across tax advisory, audit, and outsourced accounting engagements. Pricing is quote-based and not publicly disclosed. The firm became part of the Azets group (formerly Cogital), backed by HgCapital and PAI Partners (joint owner since 2024), following the 2016 acquisition. Growth has been pursued through a steady cadence of bolt-on acquisitions including Shelley Stock Hutter (2017), Westleton Drake & Hazlems Fenton (2018), Rees Pollock (2019), Greenback Alan (April 2025), and The VAT Consultancy (December 2025).
