What the Citizens Advice rating means for service excellence at scale.

The Citizens Advice star rating gives households an honest, independent look at how energy companies treat their customers. It's designed by the official consumer watchdog to help you compare providers easily.

Rather than just looking at price, Citizens Advice evaluates performance using raw data from independent sources, including the Energy Ombudsman and Extra Help Unit. The assessment looks at:

• Accurate and regular billing: Making sure your statements are clear, correct, and delivered on time.

• Reliable smart meters: Ensuring your smart meter works properly and sends automatic updates.

• Response times and complaint handling: Keeping call wait times down and resolving issues quickly and fairly.
