Business energy

information icon - E.ON

You’re a small to medium energy user if you have less than 20 sites or if you don’t have a half-hourly meter. We also take into account how much energy you use. For electricity, you need to spend less than £25,000 or use less than 1 GWh a year. For gas, you need to spend less than £15,000 or use less than 1.5 GWh each year.
You’re a large energy user if you have more than 20 sites, have half-hourly meters or use more electricity or gas than this.
