Editor's Rating


Diamond Electric offers competitive electricity rates, making it worth considering if you're planning to switch retailers. For example, Diamond charges a discounted rate of 25% off of the regulated tariff, and 5% off their rates to UOB One credit card customers. Therefore, if you have a UOB credit card and are interested in an electricity plan that is based around the tariff, then Diamond Electric is your best option.

What Makes Diamond Electric Stand Out to Consumers?

Diamond Electric charges relatively cheap rates compared to its competitors. For example, several of its plans charge 25% less than the regulated tariff, ensuring that households will consistently pay less than that rate. Additionally, UOB One cardholders can receive an extra 5% off their bill. Despite these competitive rates, Diamond Electric does not offer a fixed rate plan. This is a disadvantage because these plans are typically less expensive than tariff discounted rates, on average. Still, if you are a current UOB One customer (or will become one soon) and prefer a tariff discounted rate electricity plan, Diamond Electric might be a good fit.
