Government policies such as helping insulate homes and promoting the installation of more energy efficient boilers are helping reduce the rise in household gas and electricity bills, according to a report
Savings generated from energy efficiency policies are already having an impact and will increase over the next decade, said a report from the Department for Energy and Climate Change (DECC).
Household dual fuel bills are estimated to be on average 5%, or £64 lower now than they would be without these policies, said the report.
By 2020, average household energy bills will have risen by 6% in real terms but will be 11%, or £166 lower than they would been without government policies, the report said.
Nearly half of the average household dual fuel energy bill, or around 47%, is made up of fossil fuel prices, or £598, with the second largest cost attributed to network costs or transport and distribution of energy, at 20% or £257.
Government policies on energy and climate change accounted for 9%, or £112 of this bill - with £30 of this spent on renewable energy policies, including £9 on on-shore and £9 on off-shore wind.
The report showed 85% of the rise in household bills between 2010 and 2012 was from wholesale energy costs and network costs and 15%, as a result of Government policies.
Household energy consumption has been on a downward trend since 2005 partly as a result of energy efficiency measures already in place, according to the report.
By 2020 around 12 million boilers will have been replaced with more energy efficient boilers, the report said.
