Read moreI found William through a Facebook ad. He contacted me promptly, and came when he said he would (unlike 2 other electricians who “ghosted” me!). I was even able to track his arrival! He came and worked so hard on my house. He was polite and respectful to myself and my family, and especially to my dogs. You can see from this photo how comfortable they were with him! He did a fantastic job and will be coming back for further electrical work. I can highly recommend this lovely young man.

Read moreWilliam was completing a job across the road when I approached him. He came to our house once he had finished, quoted on installing two flood lights in our backyard and, when I accepted the quote, did the job there and then. He was helpful and courteous throughout and his work was tidy and professional. We are very pleased with the results.

Read moreWilliam installed a 42 kw battery at my residence on Monday, 8 December. Arrived at 7.30am and left after 5pm. Answered my questions and helped with more questions later. The system installed is operating efficiently, no problems. The area was left clean, all rubbish removed. I am very happy with the installation and his efforts.
