Maturity to Succession
Diesel Pro is a Hexham-based mechanical services business, specialising in truck and plant mechanics. They provide expert on-site and mobile services, keeping large vehicles running smoothly.

Diesel Pro wanted to transition 60% ownership from two founding directors to key employee shareholders. The process was complex, involving multiple parties, legal and accounting advice, and valuation negotiations. Add in financial readiness, staffing pressures, and lease talks. Without careful guidance, they could have hit stagnation, internal conflict, and missed growth opportunities.
The internal transition created a real opportunity to build the business from within. With employees’ deep knowledge, strong client relationships, and cultural continuity, the company was well-positioned for growth. Clear reporting, training and open communication could give the new owners the confidence to drive expansion and secure long-term success.
A dedicated Maxim team steered Diesel Pro through a tricky ownership handover. We kept conversations flowing between departing and incoming shareholders, provided independent valuations, and juggled legal, tax and strategic planning. With financial modelling, sensitivity checks, and hands-on education for the new owners, everyone could step in with confidence and drive the business toward long-term growth.

With our support, Diesel Pro is running more profitably and efficiently than ever, with stronger financial discipline across the business. Shareholders are actively involved in budgeting and performance tracking, and collaborative leadership with regular check-ins keeps everyone confident and on track. The business is strategically primed for growth, while new owners build financial smarts, business know-how, and leadership skills in a supportive environment.
“Initially, we just thought accounting was compliance. It wasn’t until Maxim that we found out there was so much more to running a business – the business advisory, strategic planning and things like that. We honestly feel Diesel Pro wouldn’t be what it is today without their advice and the trust we built with them.
Succession planning wasn’t on our radar at first, but Maxim guided us every step of the way. Their strategic plans created wealth in the business and set us up for a smooth succession. The Diesel Pro legacy will continue. We’re in great hands with Maxim on our side.”
“Maxim’s advisory services leading up to the sale and beyond were invaluable. We could lean on them for everything, and they gave us confidence, and still do.
Their advice was tailored to us. They always respond straight away and make us feel like we’re their only client. From strategic planning to succession guidance, Maxim made us feel supported every step of the way.”
