Making a complaint about an energy broker
If your complaint is about a broker you work with, please contact them directly. From 19 December 2024, the Energy Ombudsman Alternative Dispute Resolution Service will accept complaints from both microbusinesses and small business consumers.
What’s classed as a microbusiness and small business consumer?
- A microbusiness is a business that consumes no more than 293,000 kWh of gas or 100,000 kWh of electricity each year or has fewer than 10 employees (or their full time equivalent) and an annual turnover or balance sheet no greater than £2 million.
- A small business consumer is a business that consumes no more than 500,000 kWh of gas or 200,000kWh of electricity each year or has fewer than 50 employees and an annual turnover of £6.5 million or a balance sheet total of £5 million.
If your issue’s still unresolved after eight weeks, or you reach a deadlock, you may be able to approach the Energy Ombudsman (EO) at this point.
You can contact Energy Ombudsman on 0330 440 1624 (Monday to Friday, 8am to 8pm, and Saturday, 9am to 1pm), or email enquiry@energyombudsman.org.
The EO’s free to use, totally independent and doesn’t take sides. If you agree with its decision, your broker must act upon its recommendations.
