RSM UK Group LLP is a UK-based audit, tax, and consulting firm serving the middle market, operating from more than 30 office locations across the United Kingdom with a headcount exceeding 5,000 professionals. The firm is headquartered in London at 25 Farringdon Street and is a member of RSM International, the world's sixth-largest accounting network. Its service portfolio spans audit and assurance, corporate and employment tax, VAT and indirect tax, international tax, transaction advisory, restructuring, enterprise risk management, ESG and sustainability advisory, supply chain consulting, working capital optimization, technology and data risk, legal services, and outsourcing. Sector coverage includes financial services, real estate and construction, technology and media, consumer markets, industrials, not-for-profit, and healthcare.

RSM UK monetizes through engagement-based, custom-priced professional services contracts, typically structured as multi-year engagements with pricing determined by scope, complexity, and client size. The firm complements its human advisory work with proprietary software products: Tracker, a cloud-based credit monitoring platform for UK businesses, and Insight4GRC, a cloud-based governance, risk, and compliance platform for enterprise risk management. Distribution is primarily direct via the UK office network and the firm's transatlantic partnership with RSM US, Canada, Ireland, and Mexico (effective January 2026), creating a unified cross-border delivery platform of more than 23,000 professionals generating $5 billion in aggregate annual revenue. Go-to-market combines sales-led direct engagement with event-driven thought leadership, including regular economic outlook reports, sector surveys, webinars, and sponsorships such as BusinessCloud's Founder 250 list.

For the year ended March 31, 2025, RSM UK reported record unaudited revenue of £594 million, up nearly 10% year-on-year, with average partner payouts of £821,000, up 16% from £708,000. The firm has pursued a self-funded expansion model through Project Bamboo rather than private equity, distinguishing it from PE-backed mid-tier competitors. Recent strategic activity includes the transatlantic partnership with RSM US, an agreement in principle for RSM Mexico to join the network, multiple senior lateral hires (notably Joe Barry in restructuring and Jamie Baker in digital forensics), and four partner promotions in the Birmingham office, collectively indicating an aggressive capacity and capability buildout.
