Sampson Fielding

What Sampson Fielding does

Sampson Fielding is a London-based chartered accountancy and business advisory firm founded in November 2020 by Managing Partners Benjamin Sampson (ex-Sampson West) and Elliot Fielding (ex-Deloitte Audit and Transaction Services). Operating from a single office at 5th Floor, 36-38 Wigmore Street in Marylebone, the firm serves approximately 1,700 clients on a roughly 50:50 split between corporate entities and individual taxpayers. Headcount has grown from three founders to 25 professionals, supplemented in 2024 by the integration of two acquired practices — Blythe and Co. and Bartrum Lerner.

The firm delivers three core service lines: Business Compliance (statutory accounts, corporation tax, VAT returns, bookkeeping), Business Consultancy (profit extraction, incorporation, cashflow forecasting), and Personal Tax (tax returns, pension planning, property accounts, share schemes). Service delivery is built on QuickBooks Online as the primary accounting platform, Dext for OCR-based data extraction, and a proprietary in-house practice management software built to differentiate the firm from traditional practices. The firm is regulated by ICAEW and operates under GDPR compliance.

Revenue is generated through time-based professional services fees indexed to RPI + 1.2% annually, plus fixed-fee engagements for defined assignments. Pricing is not publicly disclosed; billing cadence is monthly for professional services and contract-based for fixed fees. Go-to-market is sales-led and partner-driven — the firm begins with a no-pressure consultation, relies on direct Partner engagement and personal networks, and supplements this with a content marketing engine (blog, quarterly newsletter, organic social) authored by qualified Chartered Accountants. The firm is privately held by its founders with no external institutional investment and funds growth from operating cash flow and tuck-in acquisitions.
