To ask the Secretary of State for Business, Enterprise and Regulatory Reform what estimate he has made of the expenditure made by each energy company on its social tariff in each of the last five years.

Detailed reporting of energy company social tariffs has been led by OFGEM in recent years with BERR reporting at an aggregate level. In August and October 2007, OFGEM reported on the range of voluntary social initiatives each of the six largest energy suppliers provide to assist their vulnerable customers.

Etimated figures for combined social spending on all voluntary initiatives (including social tariffs, rebates, trust funds, partnerships etc. but excluding differences in company fuel price levels) in 2006 by company are displayed in the following table:

Further detail on the six largest energy suppliers' expenditure on their social initiatives is available here:

Accurate figures prior to 2006 at individual supplier level are not available. OFGEM published a report of supplier activity in June 2005 but no assessments were made at aggregate supplier level.
