Bourner Bullock

What Bourner Bullock does

Bourner Bullock is a five-Partner firm of chartered accountants based at 114 St Martin's Lane, Covent Garden, London, providing accountancy, audit, and tax advisory services continuously since 1883. The firm serves a horizontal client base spanning individuals, small and large businesses, charities, and international clients, with explicit service lines for each segment plus a dedicated international offering enabled by its position as the sole UK Member Firm of the JPA International Network (150 locations across 65 countries) and its Forum of Firms listing.

The core technology base is conventional for a professional services firm: document management through the Virtual Cabinet client portal, QuickBooks Online integration for bookkeeping clients, a website-hosted suite of interactive calculators (VAT, company car, inheritance tax, stamp duty, loans, etc.), and a downloadable factsheet library covering UK tax, payroll, audit, and Making Tax Digital content. There is no proprietary technology platform, no AI/ML capability, and no disclosed product roadmap beyond the existing digital engagement tools.

Revenue is generated through time-based professional fees billed across engagement teams of partners, staff, and sub-contractors, with disbursements charged separately. Go-to-market is partner-led and relationship-driven, emphasizing year-round client contact and direct partner access. Marketing relies on content (website Hot Topics, monthly Newswire email newsletter, factsheets), calculators, and modest organic social presence on Facebook, LinkedIn and X/Twitter. Pricing is not publicly disclosed; clients are directed to contact the firm for quotes.
