A price comparison website has warned consumers they will face a 20 per cent rise in fuel bills this winter. Cold weather and rising gas prices are expected to push the average quarterly fuel bill up to a record £658. The website energyhelpline.com, which is fully accredited to the Consumer Focus Confidence Code to compare energy for domestic users, says households face a 52 per cent rise in the past month alone, with gas bills averaging £164 for the month and electricity £40.
