Ohk Energy announced as one of Ireland’s Best Managed Companies 2025
Ohk Energy receives award for the first time
26 September 2025: Ohk Energy has been named as one of Ireland’s Best Managed Companies. The company, which demonstrated superior business performance for the first year, was recognised at an awards ceremony on Thursday, 25th September.
Eight new businesses have been awarded the Ireland’s Best Managed Companies (BMC) accolade at the 17th annual awards programme. This year, Deloitte recognised 115 indigenous companies at the awards, representing 25 of the 32 counties across the island of Ireland.
The network of companies has a combined turnover of more than €22 billion and provide employment to over 62,000 people across a range of sectors from technology and healthcare to construction.
A thorough judging process precedes the recognition each year, evaluating the entire management team and the business strategy of each company. The judges examine a wide range of areas when assessing Ireland’s top privately-owned businesses, considering each business’ strategic planning, governance standards, financial performance, in addition to each organisation’s culture, talent strategy and how they are innovating year on year.
Commenting on the award Conor Foley, CEO, Ohk Energy said “Winning a Deloitte Best Managed Company award is a huge honour and a proud milestone for everyone at Ohk Energy. Our success is built on the dedication of our people, the trust of our customers, and our commitment to driving Ireland’s renewable energy future. This recognition is testament to the culture of innovation, collaboration, and resilience that runs through our business.”
