Which? Recommended Provider criteria

Our energy satisfaction survey is the first piece in the puzzle for aspiring Which? Recommended Providers. Companies must be among the highest scorers, based on feedback from their customers. 

See our full energy survey results.

In addition to our customer satisfaction survey, we also carry out detailed behind-the-scenes analysis of energy companies' practices. We award Which? Recommended Provider (WRP) status to those companies which pass our criteria, so we're confident that they're the best of the best and won't let you down. 

We also continually review and improve our criteria to make sure they're focused on what's most important to customers.

To become a Which? Recommended Provider, an energy supplier must:

• Be one of the top-ranked companies as rated by their customers, with a customer score of at least 70%.
• Have practices that we think are in the best interest of customers. We scored energy companies against a set of 15 criteria across four key areas: how well they conduct customer service, how they support customers who need it, how they deal with complaints, and how they performed against their recent smart meter targets. Which? Recommended Providers must score above average in this assessment.
