Contollo Group, a building consultancy firm backed by private equity firm NorthEdge, has expanded its portfolio with the acquisition of Engineering Services Partnership (ESP) Ltd, a Mechanical, Electrical, and Public Health (MEP) engineering services company.
Established in 1997, ESP operates from offices in Croydon, Peterborough, Manchester, and Edinburgh, offering specialist engineering expertise across sectors such as banking, data centres, retail, industrial, and commercial.
This acquisition marks Contollo’s fourth in recent times, following the integration of Abacus, MBA, and TACE into its portfolio, increasing the group’s headcount to over 160.
Ruth Percival, CEO of Contollo Group, commented: “This partnership will allow us to combine the extensive strengths and sector experience of ESP with the expertise and existing MEP capabilities of the Contollo team. ESP is a forward-thinking, innovative company with an exceptional blue-chip client portfolio. We are looking forward to working with the team and welcoming them to the growing Contollo Group.”
Philip Graham-Clare, Managing Director at ESP, added: “We’re incredibly excited about the opportunity to be part of the Contollo Group. This transaction combines our strengths and enables us to deliver additional services, increased capacity, and even greater efficiency and sustainability for our clients, something we’re very passionate about.”
This strategic acquisition aligns with Contollo Group’s ambitious growth plan to acquire approximately seven businesses across the UK over the next three years, aiming to become a leading consultancy in the built environment by bringing together smart people to deliver smart buildings.
The integration of ESP is expected to enhance Contollo’s service offerings and expand its reach across the industry. The acquisition follows a period of financial stability and growth for ESP. The company’s most recent accounts filed with Companies House highlights its potential to enhance their robust financial position.
This marks Contollo’s fourth acquisition, following the successful integration of Abacus, MBA, and TACE. With a growing team of over 160 professionals, Contollo continues its mission to revolutionise the built environment through innovative collaborations and strategic expansions.
