Before there was competition on domestic markets, the regulators set price controls fixing maximum price that the monopoly suppliers could charge domestic customers. These price controls remained in place when markets started to get liberalised, and were then gradually removed between 2000 and 2002. Ofgem’s decision to remove price controls was based on the assessment that competition was developing well at that time and that the Competition Act 1998, being effective since March 2000, would deter companies from the abuse of market power, and provide Ofgem with sufficient power to tackle any abuse. Moreover, consumer surveys showed good awareness of the ability to switch, high and rising switching rates away from the former monopoly supplies, and substantial and continuing falls in their market shares.
