What Whitley Stimpson does

Whitley Stimpson is a chartered accountancy and business advisory firm headquartered in Banbury, Oxfordshire, with a second office in Witney. Founded in 1931 and operating today as Whitley Stimpson Ltd, a private limited company registered in England & Wales, the firm serves individuals, families, and businesses across Oxfordshire, the Midlands, the M40 corridor, Buckinghamshire, and Northamptonshire. Its 51-100 employees are organized across core compliance lines (personal tax, business tax, audit and assurance, payroll, company secretarial) and specialist sector practices covering agriculture and farming, food industry, landed estates, property and construction, technology, professional practices, and personal service companies.

The firm delivers services rather than software products; its underlying technology consists of third-party cloud accounting platforms (Sage, Xero, QuickBooks, Twinfield) under formal partnerships, plus specialist payroll software for RTI compliance and auto-enrolment. Advisory and corporate finance work (business valuations, due diligence, succession planning, R&D tax credits) is positioned as the higher-margin layer around the compliance base.

Whitley Stimpson's revenue model is professional services fees, quote-based by engagement and not publicly disclosed. Go-to-market is primarily sales-led through partner-led relationships and referrals, supplemented by event-driven and community-led motions including webinars, seminars, local sponsorships, and charity partnerships. The firm has grown through mergers across the M40 corridor and was ranked in the Accountancy Age Top 100 UK firms for eight consecutive years (2013-2021). It holds ICAEW Chartered Accountants status with statutory audit registration and ACCA affiliation, and is led by a six-person director team.
