Built on Experience. Driven by Quality. Powered by Trust.

Thermo Group was founded by Luke Williams, a qualified electrical contractor and licensed Wireman with more than two decades of experience in the electrical industry.

Born and raised in Cape Town, Luke began his career in 2002, developing his expertise through years of hands-on experience across residential, commercial, industrial and construction projects throughout South Africa. His career also included 13 years in Gauteng, where he gained extensive experience in the maintenance and management of electrical systems across factories, residential facilities and large-scale developments.

After qualifying as an Electrical Contractor in 2007 and obtaining his Wireman’s Licence in 2011, Luke continued to build his expertise in electrical compliance, electrical installations, solar and backup power systems, with a strong focus on safety, reliability and quality workmanship.

From a Home Garage to Thermo Group

In 2016, Luke turned his long-standing vision into reality by establishing Thermoelectrics. The business started from his home garage with just one vehicle and one assistant.

Through a commitment to quality workmanship, reliable service and building long-term relationships with clients, the company steadily grew into an established service provider serving clients throughout Cape Town and the Western Cape.

As the business expanded and its range of specialist services grew, Thermoelectrics evolved into Thermo Group — bringing together a number of specialised divisions under one professional brand.
