We are not active on social media. Therefore we cannot accept complaints via social media.
We’re here to help

We aim to resolve all complaints within 10 working days.

If English isn’t your first language, we’ll find ways to help us communicate better. This may mean it takes a little longer to resolve your questions.
Our Complaints Process
We’re sorry if you’re unhappy with our service. Here’s what will happen next:
Step 1
- Let us know about your complaint as soon as possible.
- We aim to respond to you in 10 working days in the most appropriate way.
- If we need more time to investigate, we’ll keep you updated and try to reduce any immediate impact on you.
Step 2:
- If we can’t resolve things straight away, we’ll escalate your complaint internally.
- You can ask for a manager to review your complaint at any time.
- If we’re unable to resolve your complaint, we’ll explain our final position. You may receive a “deadlock letter” (or you can request one), confirming we can’t take things further.
Step 3:
If steps one and two have been followed and you’re still unhappy, you can take your complaint to the Energy Ombudsman if:
- You’ve received a deadlock letter, or
- 8 weeks have passed since you first made your complaint
The Energy Ombudsman offers a free and independent review, but only after our complaints process has been completed.
