From mine shafts to data centres, warehouses to hospitals — HHK delivers end-to-end lightning protection, earthing, and surge solutions built to SANS and IEC standards. One specialist.
Celebrating 50 years of expertise. Absolute peace of mind.
Southern Africa's critical infrastructure spans an extraordinary range of environments and industries, and lightning doesn't discriminate between them. Whether you operate a mine, data centre, bank, hospital, warehouse, casino, school, green energy facility, or commercial building, the risks are the same — and the consequences of inadequate protection can be devastating.
HHK has spent nearly five decades engineering protection solutions for every one of these environments, adapting our approach to the unique demands of each sector and structure type, from high-voltage industrial sites to heritage campus buildings and residential estates.
Thank you so much. I really appreciate the excellent work your team has done the workmanship looks very neat and professional.

My name is Graham Felton and I have over 50 years' experience in designing large electrical projects, 40 years as a Professional Electrical Engineer. During the period from 1985 to date I have worked with HHK overseeing numerous Earthing and Lightning Protection Installations. I found their designs, installations and their knowledge to be excellent. I would not hesitate to recommend HHK to any of our clients. I have semi-retired and do not get involved with large/ heavy power Electrical Installations, but keep active scrutinizing designs/drawings etc. to see if they comply with the regulations.

Good day,
That is a very well deserved five. From admin to the actual service. All HHK employees communicate clearly what they need to do their service and then they are extremely well organised and professional.

I was thoroughly happy with the service I received from HHK Polokwane, we were under pressure to have a lightning test done on the delivery bay mast at Bokoni Platinum Mine, because of a visit we would have from the inspector the same week, from Admin to the dispatching of the technicians everything was done promptly and the test was done before the inspector could arrive. Thank you for the good work and prompt response, I dearly appreciate it.
