Consumer advice and complaints

Consumer advice

If you are a consumer and you have an issue to resolve with an energy company please read the guidance in our section for consumers:

Please note that we do not investigate complaints or make enquiries on behalf of individuals and will only be able to refer you to the information and organisations set out in this guidance.

Ofgem Consumer Affairs

Our Consumer Affairs team manages enquiries from consumers regarding our policies and functions. It does not deal with individual consumer complaints against energy companies.

While we try to answer each call immediately, you may need to leave a voice message if we are busy taking other calls. If you do leave a message we will call you back as soon as possible.

Energy Companies Obligation (ECO)

The Energy Companies Obligation (ECO) is an energy efficiency programme that was introduced into Great Britain at the beginning of 2013. It replaces two previous schemes, the Carbon Emissions Reduction Target (CERT) and the Community Energy Saving Programme (CESP).



If you wish to share information that you believe highlights potentially dangerous or illegal behaviour by a company whose activities we regulate, you should contact our whistleblowing team.

You blow the whistle when you raise a concern about a wrongdoing, risk or malpractice that you are aware of through your work. This is not a consumer line.

You can find full guidance on our whistleblowing procedure, including contact details and information on your right to protection and anonymity, in the Transparency section of the website.
