• Competition is not a ‘free good’. Introducing competition imposes a range of additional costs that must be paid by consumers. In the case of electricity, these costs are very high and it is far from clear that the benefits will outweigh them;
• Retail electricity competition will result in a transfer of costs from large to small consumers because large consumers have the incentive, negotiating skill and resources to get the best deal from the market;
• Within small consumers, it will be the poorest consumers that do worst because competing retail suppliers will target rich consumers who consume more and who will be more likely to buy other services that their electricity company offers; and
