    positive review  The whole process was quick, easy and convenient. Everyone from the representative, the 'follow up caller' and the electricians were friendly, professional, informative and efficient. The Electricians were on time and had a great work ethic. I'm so glad I've done this.

    Daniel was within the time allocated, profesional ,worked quickly and quietly,knew his product and those being replaced. This is a great service and although the public servant from somewhere makes them jump through hoops most of which are BS the job is completed without fuss. Highly Satisfied.

    positive review  A lovely young gentleman called Gourav installed light globes, showerheads and standby power controllers for me. My daughter has an auditory processing problem and found the showerheads noisy and Gourav very obligingly found different showerheads for me, dropping everything and coming around when I called him the following morning before he had even started work. He was wonderful and I thoroughly recommend the service.
