18 January 2013: Ofgem have updated their useful factsheet on what makes up household energy tariffs (download here).
The notes states that:
- It reflects gas and electricity prices in December 2012
- The average gas bill for a standard account is £811 and for electricity it is £531
- The average bills above are based on average annual consumption figures of 3,300 kWh for electricity and 16,500 kWh for gas
- Environmental costs amount to 6% of gas bills and 11% of electricity bills – and currently amount to around £82 on a total energy (gas & electricity) annual bill.
