Electricity switches

Centrica, owners of British Gas, has warned that electricity and gas prices in the UK are set to rise in the autumn. Centrica blames this on the expected rise in the costs of wholesale gas and other non-energy inputs.

One of the other ‘big six’ energy suppliers, E.On, has responded by saying that it will not raise energy prices this year. Whether it will raise prices after 1 Jan next year remains to be seen.

Last autumn, household energy prices rose substantially: between 15.4% and 18% for gas and between 4.5% and 16% for electricity. This spring, in response to lower wholesale energy prices, suppliers cut prices for either electricity or gas (but not both) by around 5%.

The government and various pressure groups are encouraging consumers to use price comparison sites to switch to a cheaper supplier. The problem with this is that supplier A may be cheaper than supplier B one month, but B cheaper than A the next. Nevertheless, switching does impose some degree of additional competitive pressure on suppliers.

More powerful pressure could be applied by ‘collective switching’. This is where a lot of people switch via an intermediary company, which sources a deal from an energy supplier. This collective buying is a form of countervailing power to offset the oligopoly power of the suppliers. Such schemes are being encouraged by the Energy Minister, Ed Davey.

The other approach, apart from doing nothing, is for Ofgem, the energy regulator, to impose tough conditions on pricing. But at present, Ofgem’s approach has been to try to make the market more competitive (see also), rather than regulating prices.
