How billing works

How's my bill calculated?

Your gas or electricity bill is made up of two elements:

• The standing charge – the fixed daily amount that covers the costs of transporting energy to your premises and maintaining your meter. It varies depending on where your business is based. You pay the standing charge no matter how much energy you use.
  
  
• The unit rate – the price you pay for the gas or electricity you use, usually measured in pence per kilowatt-hour (kWh). Depending on your meter, you might have different unit rates for electricity, such as day and night rates. One kWh is roughly what you need to use a desktop computer for four hours.

Your electricity meter will record your use in kilowatt-hours (kWh).

Your gas meter will record your use in cubic metres or cubic feet. This is then converted into kWh.
