Ironically, technology can make the utilities’ problem worse, not better—at least in the short term. In the past, grids were developed because it was cheaper to generate large quantities of power and distribute it over wide distances, rather then generate smaller quantities closer to the place of use. It is for this reason that electricity is seen as a business that benefits from “economies of scale”.

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.

If you’re looking for a new electricity deal, you’re not alone: 319,000 electricity customers switched energy supplier during January 2018, according to OFGEM*. Shopping around for the best electricity deal is simpler than you might think – but there are bound to be a few questions. Here’s everything you ever wanted to know about comparing electricity deals.
