M&A Integration Director in London

Be a part of the next big success story in the M&E design sector. My client is busy growing and acquiring MEP design consultancies across the UK. We require an integration director who ideally has previous experience working in the MEP or Engineering sector. You will be responsible for on-boarding new acquisitions into the group to ensure the most smooth and successful integration. This role is all about taking founder/owners on a positive journey of integration into the group.

The individual will be central to delivering our acquisition-led growth strategy and the cross-sell and synergy benefits that underpin the investment thesis. Reporting to the Group CFO in the near term, the Integration Director owns a structured 100-day onboarding programme and a 12-month integration roadmap for each acquisition, working in close partnership with the M&A team, the Group CFO, the incoming Group CEO, and the Managing Directors of acquired businesses.

A defining feature of this role is the ability to navigate that context with credibility: setting group direction and standards while bringing people along, building consensus, and earning the trust of business leaders so that change is adopted rather than imposed. This is a transformation role as much as an integration role. Our platform strategy will continue to evolve with the pace and profile of the businesses acquired. The Integration Director will help shape the future operating model and target state while delivering the practical steps to get there, combining strong project management discipline with a strategic lens.
