What Wilson Partners does

Wilson Partners is a UK-headquartered chartered accountancy firm founded in 2008 in Maidenhead, Berkshire by brothers Allan and Chris Wilson. The firm operates as an integrated professional services platform spanning accounting, business and personal tax, corporate finance (M&A advisory, transaction support, valuations), statutory audit, R&D and innovation tax reliefs, payroll, and outsourced finance / virtual FD services. Its technology foundation is built on cloud accounting (notably as a Xero Platinum Partner) supplemented by a SharePoint-based client portal for document exchange, with no proprietary AI or API product layer. Customers are segmented across UK SMEs in sectors such as construction, life sciences, manufacturing, property, financial services, and technology; private equity investors requiring due diligence and portfolio support; and high-net-worth private clients needing tax, trust, probate, and US tax services.

The firm's go-to-market is sales-led and relationship-driven, delivered through a network of 11 offices across the UK (Maidenhead, Cambridge, Sevenoaks, Woking, Plymouth, Oakham, Tonbridge, Manchester, Wilmslow, Nantwich) plus Stellenbosch in South Africa. Revenue is generated through a mix of recurring monthly compliance and outsourced-finance engagements, project-based tax and advisory work, and transaction-based M&A fees. Pricing is bespoke and quote-based. Growth has been predominantly inorganic: five acquisitions completed between December 2024 and February 2026 (Craufurd Hale, Max Accountants, Lindeyer Francis Ferguson, Peplows, and Afford Bond) lifted revenue from below £35m to approximately £50m and headcount to roughly 460 staff. The firm holds ICAEW and ACCA accreditations, Cyber Essentials Plus certification, and has accumulated multiple industry awards, including EISA Best Accountant (2025 winner, 2026 highly commended) and Accounting Excellence Silver for Large Firm of the Year (2025).
