Thermoelectrics 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 and quickly developed a passion for delivering quality electrical solutions. Throughout his career, he worked on a wide range of residential, commercial, industrial, and construction projects across South Africa, including spending 13 years in Gauteng where he gained invaluable experience maintaining factories, residential facilities, and large-scale developments.

After qualifying as an Electrical Contractor in 2007 and obtaining his Wireman’s Licence in 2011, Luke became actively involved in electrical compliance inspections, solar and backup installations and ensuring installations met the highest safety standards.

In 2016, Luke turned his long-held vision into reality by establishing Thermoelectrics. Starting with just one vehicle, one assistant, and operating from a home garage, the company has grown into a trusted service provider based in Burgundy Estate, Cape Town.

Today, Thermoelectrics operates multiple specialist teams throughout Cape Town delivering:

• Electrical installations and maintenance
• Commercial and residential solar installations
• Solar maintenance and monitoring
• Electrical compliance inspections 
• Compliance certificates for transfer of property (COCs)
• Backup power and energy solutions
• Plumbing certificate of compliance
• Plumbing repairs and maintenance 

Our continued growth has been built on one simple principle: providing reliable workmanship, honest advice, and exceptional customer service.

At Thermoelectrics, we believe that every project—whether it’s a small repair or a large commercial installation—deserves the same level of professionalism, attention to detail, and commitment to quality. This dedication has earned us the trust of homeowners, businesses, body corporates, and property professionals throughout the Western Cape.

Our mission is simple: to deliver dependable electrical, solar, and plumbing solutions that clients can rely on for years to come.
