Sinewave appoints Jim Arnold as new Non-Executive Chairman


We’re delighted to announce the appointment of Jim Arnold as Sinewave’s new Non-Executive Chairman. This move further establishes us as an industry leader, equipping our incredible team with more top-level talent and experience.

Jim has over 40 years of experience in the UK infrastructure market. His leadership at M Group Services reflects a deep understanding of regulated and commercial infrastructure environments, as well as large-scale contract delivery and capital projects.

Jim’s progression as a leader and tenure as CEO of multi-billion-pound M Group Services exemplify his ability to deliver large-scale growth. He was a key presence at Morrison Utility Services for over 20 years, helping to facilitate growth and navigate change, leading them as CEO for a further 6 years.

Jim has transitioned from Executive Director to COO, then CEO, and most recently Deputy Chairman. He also brings experience in a Non-Executive Chair role at Axis CLC Group. Jim’s fundamentals lie in effectively scaling operations and professionalising highly profitable businesses. In that time, he’s demonstrated expertise in governance, strategic oversight, and succession planning.

This track record of effectively translating vision allows us to capitalise on recent growth and strive towards our greater ambitions. Jim will serve a vital role in providing strategic guidance and operational experience, helping us go from strength to strength.

At Sinewave, we have been cementing ourselves as industry leaders for some time now. From our ever-increasing capabilities to handle major projects up to 400kV, to our impact on the industry through firsts like B Corp certification and Sinewave Switch, we’re proving that we belong among the biggest and best ICP’s; in the UK and beyond.

Already showcasing our intent to scale through backing from the Three Hills Impact Fund, the addition of Jim as Non-Executive Chairman propels us further forward in our development.

“We talk a lot about the philosophy of continuous improvement internally. I believe Jim embodies that mindset as we look to push onward and upward.

Sinewave has had a lot of success and a significant amount of growth over the last decade. I am immensely proud of our ability to get this far by doing things differently, and now we’re determined to put ourselves in the best position possible for our next chapter.

Jim’s addition to the board will allow us to realise what the next phase of Sinewave looks like. His experience in futureproofing organisations is going to help keep that continuous growth mindset alive even as we scale, while we retain the core of what makes us Sinewave.” - Adam Woodley, Founder & CEO, Sinewave

“Sinewave is a great business with huge potential. I am delighted to be appointed as Non-Executive Chairman with the opportunity to support Adam and the wider management team as they continue to grow and develop the business.” - Jim Arnold, Non-executive Chairman, Sinewave
