Optimum Electrics - Excellent

Optimum Electrics were very professional, knowledgeable and easy to deal with through the whole process. The price was very competitive. We had a SigEnegy 9kw battery and a 10kw invertor along with 12 mono panels. Also a smoke detector and an Eddi/Harvi system connector to the emersion heater. All installed within 1 day.

HIES were very good at communication

HIES were very good at communication. They kept me up to date at all stages of my solar installation. It is good to feel you are backed if things were to go south although thankfully I didn’t need to use them. Their vetting of competent installers is valuable.
