Retail electricity prices have been increasing over the last five years. Deregulation of the retail market, it was hoped, would lead to reduced pricing. However the retail cost component of electricity supply appears to have increased. More recently, higher energy production costs have led to higher retail prices.
There is an argument to switch electricity suppliersannually to save money. Initial customers offers are often more attractive than offers to existing customers. Sign on bonuses may be the only difference between the real usage charges of supplier A and supplier B.
