So Energy Reviews (4.20/5)

So Energy is rated 4.20 / 5 on TrustPilot.

So Energy's TrustPilot rating is below the average rating for all of the energy suppliers we have compared.

Check out one of their latest customer reviews below:

“I had a query about the debit/credit on my bill; the customer service team member called Blessing (a beautiful name) was very helpful in explaining what I wanted to know. The 4-star rating is because I would have liked to have more advice on debit/credit when it appears on the bill. So Energy's customer service team has been good for their prompt response; not many people know this company. I guess they should stay this way, and I fear if they expand their business too much, they will become less responsive and supportive!“
