Escalation

Straightforward complaints are typically resolved within 10 working days. More complex cases — for example, multi-site utility contracts or disputed service levels — may take up to eight weeks while we gather information from suppliers, agents, or third parties.

Resolution

When we uphold or partially uphold a complaint, we will provide a clear apology where appropriate, explain what went wrong, set out corrective steps, and offer fair compensation where it is warranted.

  • Written summary of findings
  • Corrective action plan
  • Compensation where appropriate

If you remain unhappy

If your complaint about our Energy & Water service is not resolved to your satisfaction within eight weeks, you may refer the matter to the Energy Ombudsman for independent adjudication. We will provide the details you need to do so.

  • Energy Ombudsman: ombudsman-services.org/energy
  • For non-energy service complaints, we will explain any further escalation routes available to you.
