What makes up a British Gas bill?
Many different costs make up your bill
There are six elements that make up a British Gas energy bill. Find out what they are and whether each one is going up or down.
85% of a British Gas energy bill is made up from how much we charge you for the energy itself, transporting and delivering it around the country, tax and the costs of government policies. These are all ‘external’ costs. The 15% that is left is made up by our operating costs.
