To ask the Secretary of State for Energy and Climate Change what recent estimate he has made of the number of households in each (a) Government region, (b) local authority area and (c) Parliamentary constituency who have not switched their electricity supplier since taking up residence in their property in each of the last three years. (255981)

DECC holds information on customer switching relating to the total number of households which have switched supplier in each PES (public electricity supplier) area since the electricity market was deregulated.

Data on the total number of domestic electricity consumers who have switched supplier are available in section 2 of “Quarterly Energy Prices”, the latest edition of which was published in December 2008 and is available online at

Table 2.4.1 on page 23 shows the percentage of consumers who have switched supplier in each region, split by payment method.

However, the Department holds no information on customer switching relating to the length of residence in a property, and information is not available by Government region, local authority area or parliamentary constituency.
