When it comes to the electricity itself, there is no difference at all. A cheap electric supply is the same electricity, it's simply provided by a new supplier (unless you opt for green energy - more on that here). As suppliers buy and generate different sets of energy they also have different prices. What's more, you might be on a tariff that is simply more expensive, such as a standard tariff. If you decide to switch electricity don't equate a lower price with worse service.
While you have the power to shop electricity in Wichita Falls, your chosen retailer is not in charge of power lines or can help with any type of electrical emergency. The local utility is in charge of all transmission and distribution lines, including all electrical infrastructure used to power your home or business. Oncor services Wichita Falls electricity, and all emergencies (including power outages), should be called in to 1-888-313-4747.
It’s worth noting that you can switch for free with no exit fee 42-49 days before the end of your contract. Under Ofgem’s standards of conduct, energy firms have to give you between 42 and 49 days’ notice of your tariff ending. You can use this time to decide whether to stick with them, or switch. If you decide to switch, you won’t be charged an exit fee.
