M&A Integration Director

M&A Integration Director - 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 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 Role

we are seeking an experienced Integration Director to lead the on-boarding, integration and transformation of every business acquired into the platform. 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.

Our acquisitions are typically founder-led businesses, many built over two decades or more, each with established ways of working. 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.

Key Responsibilities
Integration Planning and Execution
Accountable: 100-day plan, 12-month roadmap, weekly integration governance
•
Design and deliver a structured 100-day onboarding plan for each acquired business, covering operational, systems, financial, commercial, cultural and people work streams.
•
Develop and execute a 12-month integration roadmap to bring each business into alignment with group operating standards, KPIs and commercial targets, recognising that some milestones will extend beyond 100 days and need prioritising against wider group activity.
•
Facilitate weekly integration calls with acquired business leadership, the Group CFO, the M&A team and functional leads, maintaining clear agendas, actions and progress tracking.
•
Build and continuously improve the integration playbook, stripping it back to the core set of actions mandatory for every acquisition while tailoring deal-specific actions to diligence findings, so that each successive acquisition benefits from lessons learned.
•
Identify and escalate risks early, and drive issue resolution across work streams to maintain pace and quality.

Systems and Technology Integration
Consulted, partnering functional and technical leads: ERP, CRM, finance, Microsoft 365
•
Coordinate migration of acquired businesses onto group core systems, including Deltek Vantagepoint (group ERP for project, billing and utilisation data), Hub Spot (group CRM), the group finance and reporting platform, and the Microsoft 365 stack.
•
Sequence systems adoption sensibly: finance reporting as an immediate and compulsory requirement for group visibility, CRM adoption supported by a clear demonstration of the cross-sell benefit to each business, and ERP rolled out at a measured pace to avoid imposing unnecessary bureaucracy.
•
Support data migration and quality assurance across system transitions, including the move to timesheet and utilisation discipline where businesses do not already operate it.
•
Work with technical and functional leads to align acquired business technology with group architecture and standards, including the Deltek to Hub Spot connection and project profitability reporting.
