Launching in August 2026, the combined business will bring together more than 300 professionals across 11 offices, creating one of the UK’s largest independent mid-market full-service advisory practices. The merger will also give KR8 Advisory a Scottish presence for the first time, through Quantuma’s existing offices in Glasgow and Edinburgh.

The enlarged firm will combine expertise across advisory, restructuring, insolvency, forensic accounting, valuations, eDiscovery, real estate, tax and transaction advisory services. The move reflects growing demand from businesses, lenders, investors and professional advisers for integrated solutions that draw on multiple specialisms to address increasingly complex challenges.

Michael Cauter, CEO of K3 Advisory Group, said: “In our experience, clients and their advisers want access to broader expertise, deeper specialist capability and joined-up thinking through a single relationship.

“Bringing KR8 Advisory and Quantuma together creates a business with the scale, reach and multidisciplinary capability to meet that demand. We are creating a full-service advisory platform that supports clients across the entire business lifecycle, from growth and transactions through to navigating change and challenge.

“The KR8 Advisory brand has been built around advisory work and provides a clear, differentiated platform for growth. Combined with the expertise, relationships and reputation developed across Quantuma, we believe this creates something genuinely distinctive in the market.

“Our ambition is simple: to build a leading multidisciplinary advisory practice with the capability, culture and energy to compete for the most complex and high-value work in the UK mid-market.”

Operating as a single national brand, the combined firm aims to strengthen its ability to win larger mandates and to invest further in technology and talent. Further news on the rebranding of Quantuma’s corporate finance business is expected to follow.
