Ombudsman Services: Energy

The Ombudsman provides independent and impartial advice - and their service is free. We'll commit to any decision the Ombudsman makes, which may be different to our original outcome. This may include an apology and explanation of the findings, taking appropriate action to put things right, or compensation. You can then decide if you want to accept their decision, or ours.

What is a micro business?

You're a micro business if you meet any one of the following conditions:

  • Use less than 100,000 kWh of electricity a year
  • Use less than 293,000 kWh of gas a year
  • Have fewer than 10 employees (or their full-time equivalent) and your yearly turnover, or yearly balance sheet, is not more
    than 2 million Euros.

The consumption threshold applies to the fuel being supplied.
