Star ratings explained

We calculate a star rating for each measure for each company. The more stars a company has, the better. We looked at four core areas of customers’ experience.

 
 

Bill accuracy and clarity:

Customers’ opinions on how accurate their energy suppliers’ bills are and easy they find them to understand.

Customer service (phone and online):

How well customers feel their suppliers deal with their queries.

Dealing with complaints:

How well customers feel that their complaints have been handled by their energy company.

Helping you understand and reduce energy consumption:

Customers’ opinion on their supplier's efforts to help them know how much gas and electricity they’re using, and how they could be more efficient.

Value for money:

The extent to which customers feel they get value for money from their supplier. This is not price.

Customer score:

Customers’ overall satisfaction and their likelihood to recommend their energy company to a friend if asked.
It is not directly linked to the star ratings.
