“When I signed up with Diamond Energy in April 2011, they were a relatively small company.  The main thing that stood out for me was their customer service, we had just installed a 4 KW solar system and they assisted us to get us online. The customer service department were excellent and explained everything in layman’s terms. In all areas of retailing today customer service is sadly in decline, and that is to the detriment of those companies, not so with Diamond Energy it is what keeps customers with them, it is one of their major strengths. I would not hesitate to recommend them to anyone.”
