What customers have to say about us

Fabulous customer focussed service, particularly from Abbie and Caroline who both listened to my (complicated) issue and calmly and efficiently found a solution.

David Customer

Would recommend SmartestEnergy Business. I had great customer service from Charles. He was very helpful and informative made everything clear and was always at the end of the phone at every stage to help me with my electricity and gas contract renewals.

Jackie Customer

Of all the energy companies we have dealt with over the years, this is, by far, the easiest to deal with - easy to speak directly with someone, prompt responses to queries, good selection of options and a friendly, helpful manner. Would recommend to anyone.

Customer

Customer service 10/10 - dealt with my query quickly and efficiently. Highly recommend.

It has been a long while since I have had such an impressive service from an energy supply company. Amy tried her very best to help resolve a situation, which wasn't really the responsibility of SmartestEnergy Business at all.

Andrew Customer
