Sell-side advisory

London – Alantra has acted as the exclusive financial advisor to Mornington Partners and the wider shareholder group on the sale of Rock Compliance, a leading national provider of critical water and air compliance services, to Andwis, a technical services platform backed by H.I.G. Capital.

Rock Compliance is a leading national provider in the water and air compliance sector, supporting commercial buildings in meeting regulatory requirements through planned preventative maintenance and remedial work. The business has grown through the successful acquisition and integration of seven regional providers, creating a strong foundation for further expansion.

This strategic acquisition allows Andwis to expand its capabilities to deliver market-leading solutions in Water and Air Hygiene, Water Treatment, Commissioning and Training. Rock Compliance, in turn, gains access to Andwis’ operational expertise and resources, positioning the business for further professionalization and expansion.

Robert Pearce, Director at Alantra, said: “We are delighted to have advised Mornington Partners and the Rock Compliance team on this strategic transaction. The deal underscores the strong fundamentals of the water and air compliance market and the attractiveness of Rock Compliance as a platform for further consolidation. We are excited to see the business continue to expand under its new ownership.”

This transaction highlights Alantra’s deep sector knowledge and advisory capabilities in the Business Services and TIC (Testing, Inspection & Certification) markets, having recently advised Kester Capital on its investment in The Boundary and Exponent on its investment in Ethos Engineering.
