Some background facts on UK domestic energy supply

1)      About 60% of UK householders say that they have never switched suppliers.

2)      The number of switchers is tending to fall. 22% of electricity customers switched in 2006, falling to 17% last year. The gas numbers were similar.

3)      Only 13% say that they have recently checked prices.

4)      Ofgem research suggests that ‘5-10%’ of householders ‘proactively’ search for better prices. Up to 90% of people were shown by their consumer research to be ‘disengaged’ or ‘passive’.

5)      The last check by Ofgem indicated that there were about 320 different tariffs available in the UK domestic market (January 2011). This is up from about 170 four years before.
