Making a complaint: Let us know if something isn't right.


If you’re not happy, we’re not happy.

Why? Because giving you the very best service we can is important to us.



Our Complaints Handling Procedure.

What is a complaint?

A complaint is any contact from, or on behalf of, a customer or potential customer who is not satisfied with any part of our service.

What to expect.

All of our Energy Specialists are energy experts and go through extensive training to take full ownership of your complaint from start to finish. They're empowered to make decisions in order to provide you with the best possible resolution to your complaint.

Firstly, tell us about your complaint.

We’ll work together to resolve it. Our Energy Specialists aim to find a resolution that works for everyone involved.

We’ll say sorry, offer to give you an explanation and fix any mistakes. We may also offer you compensation in appropriate circumstances. We aim to resolve most complaints straight away, but more complex cases might take us longer.

Don't worry though, we'll keep you in the loop so you know what's happening and what to expect next.

  • Email us at hi@sainsburysenergy.com
  • Call us on 0808 501 5277, Monday to Thursday 9am - 5pm, and Friday 9am - 4pm.
Not satisfied with the outcome? Let us try again.

You can ask for, or we’ll get you a second opinion from another expert or manager to reach a fair outcome we’re all happy with. Together, we’ll agree how and when we’ll keep you up to date on your complaint’s progress.

The Energy Ombudsman.

Is a free, independent and impartial service. If we don’t agree on a resolution, you can contact the Energy Ombudsman if we’ve sent you a final offer letter or if we haven’t resolved your complaint within 8 weeks.

  • Apologise.
  • Give an explanation.
  • Take action to correct things for you.
  • Award compensation.
