The Department for Energy and Climate Change will today release the latest figures for the number of families in fuel poverty.
But the figures are expected to show a drop in fuel poverty due to a change in definition by the department last month.
The new data will include the confirmed figures for 2011 and projections up to 2013.
If you are concerned about staying warm this winter, you can get advice from Macmillan Cancer Support by calling 0808 808 00 00, or by visiting the website.
Mike Hobday, director of policy and research at Macmillan Cancer Support, has said that cancer patients are in a "dire" situation facing high energy costs combined with a lower income.
The cancer charity Macmillan has warned that around 27,000 cancer patients in the UK could be in debt as a result of falling behind on their energy bills.
A survey of 535 people who have been diagnosed with cancer in the last two years found that:
- 5% of respondents are currently in debt to their heating provider
- 54% are worried about the cost of heating their homes this winter
- 30% have had to turn off the heating in the last three months to save money
- 34% have put on outdoor clothes indoors to keep warm
Around 300,000 more homes are likely to have been pushed into "fuel poverty" by Christmas, a campaign group has warned.
The Fuel Poverty Advisory Group says six million people are now struggling to pay their energy bills.
It comes as the industry regulator Ofgem announced a multi-billion pound network upgrade, adding yet more to the bill of every consumer.
Stephen Douglas reports:
- Compare energy suppliers on a price comparison website
- Monthly direct debits, online accounts and dual fuel deals can be cheaper
- Insulate your home's loft and cavity walls
- Handheld energy monitors can estimate how much you're using in real time
- Turn your thermostat down - just 1C could cut your bill by £55 a year
- If you have an old gas boiler replace it with a new condensing model
- Stop heating escaping through gaps in windows and doors
Energy Secretary Ed Davey said he does not want to add "a single penny" to energy bills that isn't in the public interest.
Speaking at the Fair Energy Summit in London, Mr Davey said, "I'm quite frankly fed up with commentators suggesting the Government are deliberately increasing energy bills, when in fact we are doing everything we can to reduce them".
"The bulk of the cost we add to bills is for supporting low carbon technologies and energy efficiency ... I make no apology for ensuring that we meet our legally-binding carbon targets and renewable energy targets", he added.
Under Ofcom's revised proposals, household energy bills will rise an average of £12 per year between 2013 and 2021.
The amount is not cumulative as investment and costs "vary year-on-year".
Ofgem said energy bills are expected to rise from today's prices in the following manner:
- 2013/14 - £8.50
- 2014/15 - £7.30
- 2015/16 - £11.20
- 2016/17 - £11.60
- 2017/18 - £13.30
- 2018/19 - £14.50
- 2019/20 - £14.20
- 2020/21 - £15.10
The energy regulator said half the total average bill - £6.20 - is related to tax changes affecting the gas distribution network companies "that are outside Ofgem's control".
Ofgem's £24.2 billion investment to "upgrade and renew" the country's gas and electricity infrastructure includes funding to connect around 80,000 fuel poor households to the gas grid, "helping them benefit from cheaper fuel".
Household energy bills are set to rise by £12 per year to pay for new and upgraded gas and electricity infrastructure, Ofgem has announced.
