The consumer has the choice between buying from their local utility (Local Distribution Company - LDC) or from one of the deregulated suppliers. There is a large range of contract options from a variable price to 1,3 or 5 year fixed prices. Electricity provider switching is difficult once the consumer is in one of these contracts, unless they are close to the end of a fixed price contract. However, as of January 2010 there is a maximum termination penalty allowed.
Switching electricity supplier could shave pounds off your bills. But it’s not always about how much hard cash you could save. You might be fed up with poor customer service, you might want greater visibility of your usage through an app or you might want to choose your supplier based on their green credentials, or whether they supply a smart meter.
