What our Performance Pledge means to you

We aspire to deliver a quality service every single day. If you feel we have failed to meet any aspect of our Performance Pledge and you have not been able to resolve this with our Customer Service team, you can escalate your query to our complaints department at complaints@coronaenergy.co.uk.

*On-time transfers ‐ There are two circumstances which may cause your supply to start late; if your current supplier objects to the transfer of your supply or if you fail to provide sufficient detail so we can register your site on time. This includes Emergency Contact details if your supply point uses more than 732 000 kWh per year.

Our Complaints process

We work hard to ensure that all our customers get the best possible service from Corona Energy. Sometimes things can go wrong and when they do we want to resolve them as swiftly as possible for you.

There are two steps in our complaints process:

If you are a microbusiness:

If, after eight weeks, we can’t resolve your complaint or you are not satisfied with our decision, you have the right to refer your complaint to the Energy Ombudsman.

The Energy Ombudsman is an independent body who arbitrate between customers and suppliers. The service is completely free to use. The Ombudsman has the authority to resolve a complaint and suggest corrective action to be taken by us or you. If you accept the Ombudsman decision it is then binding on us and we must put in place a remedy that is required. You can decline a decision by the Ombudsman and take your complaint elsewhere such as the courts.
