The best thing about dealing with DE is that I can call a number and deal with a real person immediately without having choose from lots of options and listen to all sorts of disclaimer, recording etc messages.

Diamond Energy has been great at setting up my new account
Diamond Energy has been great at setting up my electricity account when I shifted from a big, CSG-supporting institution. It was so nice to speak to the same friendly customer service person and see them guide this transition through quickly and easily. So glad to be part of a clean, green electricity company that’s human-scale.

Having a direct line to speak to a person from Diamond, who knows their product - and if they don't know something - they get the relevant person to call.
Always courteous, helpful and timely. Trustworthy.
