Some households in Britain may begin to see their energy bills rise due to new changes coming into force on Sunday, January 1.
However, not every household will be affected by the changes equally and differences will occur depending on which part of the country they live in and how they pay for gas and electricity. The hike will hit hardest for those who live in North Wales and Merseyside who don't pay with direct debit.
For this group, bills are set to rise by more than £5 per month between January and April. Meanwhile, bills will decrease for those in the north of England - averaging at around £3.90 less. The changes are made to the amount a person's energy suppliers charge per unit of gas and electricity they supply.
