“Can I say a big thank you to you for such a great job. We had 24 panels over three aspects of our rather difficult roof - being 100 year old converted bungalow the roof tiles were a little bit of a pain. The team handled it brilliantly and the solar skirts really finished the install off beautifully.”
“Excellent Emergency Electrician over Xmas. I had a complicated issue with a solar inverter cutting the supply to the house. Smart attended and worked their way through the issue and made a temporary repair to get us through Christmas. Andre was fantastic - highly recommend.”
“Needed a small electrical job done ASAP, issued a very reasonable quote & also had someone out to me the same day, 5☆ service given. Would definitely recommend & would not hesitate to use again.”
“Excellent service from Future Smart, I was able to get an electrical installation condition report for a house sale arranged to suit my timing. They did a very thorough inspection, discussed the result after. The report was issued promptly.”
“Bruce was a star, he explained everything we needed to do over the phone, gave us a great tracking option so we knew when he would arrive (he was early) and made sure we had everything we needed. He is a credit to a great company. Thanks for your help pal!”
