About BLG Electrical
Founded in 2021, BLG Electrical is a locally owned and operated electrical business based in the Southern Highlands of NSW. We were built on a simple idea: do great work, communicate clearly, and treat every project — big or small — with the same level of care and professionalism.
Over the past few years, we’ve grown from working primarily on residential jobs to delivering electrical solutions across domestic, commercial, and industrial projects throughout the Highlands. Whether it’s a new home build in Mittagong, a renovation in Bowral, or a commercial fit-out in Moss Vale, our focus is always the same — safe, reliable, and high-quality electrical work that our clients can trust.
We take pride in offering practical advice, competitive pricing, and free quotes, so our customers always feel informed and confident before moving ahead. Every job is completed to a standard we’re proud to stand behind.
Meet The Founder
BLG Electrical was founded by Billy Grose, a fully licensed electrician with a passion for quality workmanship and problem-solving. With years of hands-on experience across residential, commercial, and industrial electrical projects, Billy built BLG Electrical to be a business that prioritises integrity, reliability, and strong client relationships.
Billy is known for his practical approach — taking the time to understand what each client actually needs, rather than offering generic solutions. From designing electrical layouts for new homes to troubleshooting complex data and connectivity issues, he brings both technical expertise and a genuine commitment to getting the job done right.
