To try to prevent these customers from being further ripped off, the government is planning to implement an energy price cap, which will require Ofgem to set a maximum amount that suppliers can charge on their standard tariffs until 2020.

Fixed-rate, long-term (contract) plans provide stability in electricity rates. If market energy costs suddenly trend upward where you live, you can rest assured that you won’t have to pay more out of pocket. However, if you want to switch to a different, lower-cost plan before the end of the contract term, you’ll likely have to pay a cancellation or early termination fee.
