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.
