What Oury Clark does

Oury Clark is a UK-based combined accountancy and legal practice founded in 1935, headquartered in Slough with a second office in London. The firm provides integrated professional services spanning chartered accountancy and tax advisory, regulated legal services (employment, property, corporate and private client), financial planning, insolvency, HR and recruitment (Arlington Recruitment), sustainability and ESG advisory, and dedicated international business expansion support for overseas companies entering the UK and UK companies going abroad.

The business is structured as a private partnership with multiple wholly-owned entities (Oury Clark Chartered Accountants, Oury Clark Solicitors, Oury Clark Consultants LLP, Arlington Recruitment Ltd, and the 2024-acquired American Tax Returns Ltd), operating under three core UK regulatory authorisations: ICAEW (audit registration), FCA (financial services), and the Solicitors Regulation Authority. The firm holds no proprietary technology platform; its core 'product' is regulated human advisory delivered through a multi-discipline partner bench of roughly 30+ partners and directors. Supporting content assets (Quick Guides, Tax Cards, the Business Without BS Podcast) function as lead-generation rather than monetised software.

Revenue derives from fee-based professional services (retainers and project engagements), with pricing not publicly disclosed. Go-to-market is sales-led: direct client relationships, referrals from a 14-country 'Firm Friends' network, government partnerships with the Department for Business & Trade and London & Partners, and conference/event presence at SXSW London and London Tech Week. Customer segments include UK SMEs and corporates (primary), individuals and families (secondary), and overseas scale-ups seeking UK market entry (secondary, growing). The firm claims 'tens of thousands' of businesses served over 85+ years and reports helping approximately 300 businesses per year through its London & Partners Gold Membership.
