There are several reasons that some energy suppliers end up being cheaper than others. The largest energy companies, also known as the Big Six, often do not need to offer rates that are as competitive as smaller companies. This is because they are more recognisable names and therefore can always rely on a steady base of customers. You can avoid this and save money by switching to a cheaper provider.

Minimum Usage Fees: Often set at or around 1,000 kWh/month, these fees mean you’ll always pay for at least that amount — even if you only use, say, 800 kWh of electricity some months. It sounds nasty, but it’s only something to be concerned about if your electricity bills historically show you hover right around that minimum use threshold. If you’re electricity use always exceeds that amount, it’s like it’s not even there.

uSwitch 2018 customer ratings are based on an independent YouGov survey that was conducted between 7 November and 1 December 2017. A total of 17,313 UK energy customers were asked to rate their energy supplier on overall satisfaction, transfer process, value for money, customer service and how likely they were to recommend. We equally weighted those five scores across suppliers with at least 50 responses to create an average supplier rating for each.
That means that customers in Houston paid an average of $5,500 more for electricity over a 14-year time span beginning in 2002, according to the group that buys electricity on behalf of municipal governments in Texas. The calculation, which uses data from the U.S. Energy Information Administration, assumes monthly electricity use of 1,300 kilowatt hours.
Unlike with long-term plans, monthly, variable rate (no-contract) plans have no cancellation fees. You won’t have to pay a penalty if you decide to take your business elsewhere because you found a better deal. Plus, you won’t be left paying more than you should if the market rate for energy trends down. However, if the market prices rise, you’ll have to pay more than those who are in-contract.
