What GD O'Hehir Co does

G D O'Hehir & Co Ltd, trading as GDO Accountants, is a UK-based chartered certified accounting firm headquartered in Spennymoor, County Durham. Founded in 1986 by Geoff O'Hehir and now led by his son Paul O'Hehir (FCCA), the firm provides accounting, tax, and bookkeeping services to sole traders, partnerships, limited companies, landlords, and small-to-medium local businesses across England. The core service portfolio spans statutory compliance (Year-End Accounts, Business Tax / Corporation Tax, Self-Assessment Returns, VAT Returns including Making Tax Digital, Companies Secretarial, and Payroll with auto-enrolment) alongside advisory modules (Tax Planning & Advisory) and a Cloud Software Setup offering covering Xero, QuickBooks, Sage, and FreeAgent. The firm operates a proprietary client login portal that integrates with the cloud accounting platforms it supports, and delivers services both remotely and face-to-face.

The firm's revenue model is a traditional professional services model with recurring compliance fees and project-based advisory work, packaged as fixed-fee engagements with an initial free consultation to lower acquisition friction. Go-to-market is sales-led and local: a WordPress/Elementor website, organic LinkedIn and Facebook presence, free consultation offers, and referrals. Technology is entirely partner-licensed third-party cloud accounting software — there is no proprietary platform, no proprietary IP, no AI/ML components, and no mobile app. Distribution is direct to the client with a self-serve client portal for document and software access.

GDO is a family-owned private limited company (Company Number 04512519), founder-managed by Paul O'Hehir with no external investors, funding rounds, subsidiaries, M&A, patents, trademarks, or regulatory actions on record. Operations are stable and the firm has been continuously operating in Spennymoor for over 20 years with a stated 7+ person team of which two are Chartered Accountants, one is an FCCA-qualified Owner, and the remainder are qualified or qualifying accounting and payroll staff.
