After the supply rates skyrocketed this year with National Grid, I found Renaissance Power and Gas listed as the least expensive supplier without any kind of cancellation fees on the gov. energy switch website. I wanted to double check that all the rates were fixed and had a couple of other questions, so I reached out through their "message us" link under support on their website. Their reply was incredibly fast, polite, and informative. I decided to give them a try, and I have not been disappointed. They even reached back out to me in the same chat a month later to verify that I hadn't experienced any problems switching. In case the above average customer service wasn't enough, we saved over $250 on our most recent electric bill with roughly the same usage. No hidden fees, no catch. I'm very pleased!.
