Jake from JPG Tech was able to come out on short notice to perform an electrical safety check on my new home. He was also able to rectify any issues he found while on site in a timely manner. Highly recommend.
Thank you Jake for coming to us so quickly to fix our problem. Great service yet again. Can't recommend more highly.
Jake recently installed new Downlights and fans, and upgraded switches and outlets in our home. His service was timely and professional and the results are exceptional! He has completely transformed our home and I strongly recommend you call JPG Tech for your electrical needs.
Great operator. No problems, reasonable price, good communication. Would use again.
Amazing from start to finish!!!
From initial contact, quoting, booking the job, doing the job then supplying certification etc afterwards, it was all done with professionalism and ease.
Jake Gretton is the owner and licensed electrician at JPG Tech, with over a decade of experience across residential, commercial, and agricultural electrical work throughout Victoria. He holds a Registered Electrical Contractor licence (REC 31422) issued by Energy Safe Victoria and completed his trade qualifications at the Institute of Technology Melbourne. Every job is carried out by Jake personally, backed by full public liability insurance and a lifetime warranty on workmanship.Rowville is one of JPG Tech's busiest service areas.
The suburb's 1980s and 1990s housing stock generates consistent switchboard upgrade and rewiring work, and the commercial precinct along Stud Road and Wellington Road keeps Jake busy with data cabling, generator installations, and security fit-outs for local businesses. Jake has completed electrical work at Rowville Health and a number of commercial properties across the Knox area, and knows the suburb's mix of residential and light industrial demands well.

There are no materials markups, no overtime charges, and no after-the-fact additions. Common Rowville jobs including switchboard upgrades, LED downlight installations, EV charger fitouts, and data cabling installations are all quoted this way.

Commercial work includes data and communications cabling, backup generator installation, security and CCTV systems, commercial lighting fit-outs, and general electrical work for businesses along Stud Road, Wellington Road, and surrounding light industrial areas.

Possibly, yes. Homes built during Rowville's main development period carry switchboards that are now 30 to 40 years old. Many do not have RCD protection on all required circuits, which is now mandatory under Victorian law, and may not have the capacity for modern household electrical loads including EV chargers, ducted air conditioning, and induction cooktops. JPG Tech offers a free switchboard assessment as part of any on-site quote, so you know whether an upgrade is necessary before committing to any work.
Yes. JPG Tech installs commercial backup generators for businesses, medical facilities, and light industrial premises across Rowville and the City of Knox. The service covers generator supply and installation, automatic transfer switches for seamless failover, load testing, and compliance certification. We size the system to your business's actual power requirements so you are not paying for more capacity than you need. Residential generator installations are also available for homeowners where power continuity is a priority.
