Mitchells Grievson

What Mitchells Grievson does

Mitchells Grievson is a chartered accountancy and registered audit firm established in 1990 and headquartered in Bishop Auckland, County Durham, in the North East of England. Operating as Mitchells Grievson Limited (Company Number 06527386), the firm is privately held and owner-operated with no disclosed external investment. It delivers a full-service practice covering audit and accountancy, taxation (including tax planning, CIS tax refunds, and Making Tax Digital for VAT compliance), bookkeeping and payroll bureau services, company secretarial support, credit checks, HMRC investigation representation, and business lifecycle advisory from start-up through growth to exit preparation. The core technology stack is standard UK accountancy software augmented by HMRC-API-integrated MTD-compatible tools for VAT submissions; no proprietary platform, API, or AI capability is offered.

The firm serves a distributed SMB and mid-market client base across the UK — from self-employed individuals and sole traders to medium-sized companies requiring statutory audits — alongside a dedicated healthcare specialism for GP practices, Primary Care Networks, and medical professionals, led by Director Phil Harnby FCA. Go-to-market is sales-led and largely referral-driven, supported by a fixed-price multi-year engagement model, a factsheet-rich website, monthly email newsletter, and organic social presence on LinkedIn, Facebook, and X. Distribution is direct through qualified accountants via in-person meetings, phone, email, and a client portal. Partnerships with the North East Business Support Fund (as a registered provider for SME grant funding) and Thornfields Training / First Practice Management (delivering national finance webinars to medical professionals) extend the firm’s regional authority and healthcare vertical reach beyond its single Bishop Auckland office.
