The initial contact came from 2 gentlemen door knocking in our estate which I am never thrilled by, however the guys at Think Renewable were very friendly and respectful and had a wealth of knowledge. Think Renewable never rushed us into a contract or hassled us to go through them and that's what sold us. I cannot recommend them enough!

Getting solar at our home with Think was an easy and pleasant experience. From our first contact and contract signing with sales person Mark to working with the installation team all went without a hitch. Their installation follow-up was spot on when I had trouble connecting my phone to the system. They had someone there the next day. We are glad we took the step to solar.

After shopping around looking for solar panels for our group of medical centres, we stumbled across Think Renewable. Issy our sales contact was prompt, attentive and provided various quotes for our choosing based around return on investment. We are thoroughly delighted with Think Renewables sales, service and install process. We have seen a dramatic decrease in our electricity bills already. After having solar installed by other providers for a few of our other practices, Think Renewable has decreased our electricity bills far greater than any other provider. I can’t recommend Think Renewable enough
