Started by Tom and Michael Kirby in Limerick in 1964, the company directly employs over 1,400 staff across Europe, with total revenues of €454m.

Kirby is a leading provider of mechanical and electrical engineering contracting services, as well as specialist power (high voltage (HV) and medium voltage (MV)) design and construction services, with clients across sectors including life sciences, industrial, renewables and data centres.

Since its establishment almost 60 years ago, Kirby Group Engineering has consistently stayed true to its core values of ‘People’, ‘Safety’, ‘Quality’, ‘Delivery’ and ‘Value’.

Digital technology

Kirby has embraced the possibilities of digitisation within engineering, using state-of-the-art 3D technology to facilitate off-site manufacturing wherever possible. This has enhanced quality and safety as well as offering a more efficient and cost-effective service to its valued clients.

To this end, the company has appointed Mark Danaher, Associate Director – BIM/ Technical Services, to head up a large-scale transformation of practices, which will include the rollout of software to centralise information, the creation of a data environment at Kirby, the implementation of AI as an IT support system for staff, and the further development of Kirby’s digital construction hub. Mark Danahar’s new role is one of a range of senior appointments announced in 2022.

Kirby Group bursary

To run alongside other schemes for nurturing talent, such as its successful apprenticeship and graduate programmes, Kirby introduced a bursary programme in 2022. The company awarded bursaries to four female students at third-level institutions across Ireland as part of its ongoing drive towards gender diversity in the fields of engineering and construction. The bursary scheme was open to women studying electrical, mechanical or building services engineering. This offers academic scholarships, along with paid placements on some of Kirby’s international projects with mentorship and guidance from senior engineers.


Kirby has a strong history of leading community and charity projects, and September 2022 saw the inaugural Kirby Way Cycle, a mega-charity event that involved 180 cyclists setting off from Kirby’s headquarters in Limerick and cycling to Dublin via Galway. Participants included employees, friends, families, clients, and supply chain partners. It raised almost €500,000 for Kirby’s chosen charities; the Galway-based National Breast Cancer Research Institute and Self-Help Africa.

Continuing its tradition of supporting those in need, Kirby donated more than €100,000 to charities in Ireland and abroad last Christmas, with Focus Ireland, UNICEF, The Society of St Vincent de Paul and Cliona’s Foundation the recipients of €50,000, €25,000, €15,000, and €12,000, respectively.

Commenting on the company’s achievements and projects, Mark Flanagan, Group Managing Director, Kirby, said, “We’re immensely proud of the huge strides we have made in the past 12 months, not just in terms of delivering top-quality services to clients globally across sectors such as data centres, industrial, life sciences and energy, but also in terms of the ongoing drive towards fostering an inclusive workplace where every staff member feels part of a sustainable, dynamic and progressive team. The camaraderie witnessed at our hugely successful Kirby Way Cycle in September, and our business results across Europe are testament to that.”
