MERCURY ENERGY CUSTOMER REVIEWS
With Mercury Energy and Hop Energy, you’ll benefit from exceptional customer service, competitive pricing, 24-7 emergency services and much more but don’t just take it from us, hear what our customers are saying!

Lisa is wonderful. She is pleasant and always polite and knowledgeable. I’m happy with the service.

Mercury is one of the FEW companies where your treated like a person not just an account number. They LISTEN to you and work with you to not just satisfy their own needs but yours as well. Ask yourself what thats worth in todays world.

We’ve been customers of Mercury for 35 years. They have always been very responsive to anything we needed. This morning’s phone call about the pre-pay price plan was no exception. The young woman I spoke to was lovely, helpful, and informative.
