Our complaints process
If our Customer Service team can’t resolve your complaint within one working day, our Customer Care team will get in touch. This team will then update you every five days until the complaint’s resolved.
If you’re unsatisfied with our Customer Care team’s progress, you can escalate your complaint. One of our agents will pass your case to a senior member of staff to review. Please email firstname.lastname@example.org and we’ll respond within five working days.
If your issue’s still unresolved after eight weeks, or we reach a deadlock, we’ll let you know. Depending on the size of your business, you may be able to approach Ombudsman Services: Energy (OSE) at this point. See further details below.
