Lennon group is an established, family-run Irish business with 45 years of experience in the electrical and energy sectors.
Based in County Louth, the group has grown from its electrical contracting roots into a multi-division business, delivering electrical, security, renewable energy and home retrofit solutions across residential, commercial and industrial sectors.
Our businesses include Lennon electrical, Lennon alarms, Lennon solar and Energyhaus, our home retrofit specialist sister company.
While our business has evolved significantly over the years, our commitment to quality workmanship, technical expertise, customer service and long-term relationships remains central to everything we do.
As we continue to grow, we're investing in our people, developing our teams and creating opportunities for experienced tradespeople, technical specialists and those looking to build long-term careers within the industry.
From electrical installations and large-scale commercial projects to solar PV systems and whole-home energy upgrades, our teams work across a diverse range of projects, bringing together experience, innovation and practical expertise.
We're proud of our heritage as a family business and the contribution our employees have made to our growth over the past 45 years. We believe in supporting professional development, encouraging progression and providing a working environment where people can build their skills and careers.
