Which? Switch tariff ratings explained
Which? Switch not only enables you to compare energy companies by looking gas and electricity prices, but also by looking at the customer service rating of each company.
Our ratings are calculated using our Which? Switch customer satisfaction survey data for customer service.
How we rate energy companies for customer service:
- Our annual Energy Customer Satisfaction Survey asks members of the public to rate their supplier in a number of categories, including value for money, energy saving measures and their experience of customer service
- We assign a score out of five for each category to companies based on energy customer responses
- We try to include as many energy suppliers in our survey as possible, in order to allow ease of comparison across companies both large and small
How to compare energy companies by customer score:
- On the Which? Switch results table, the star rating assigned to a company reflects their score for customer service
- To rank energy companies by customer service rating, simply click the ‘Which? Switch tariff rating’ link at the top of your results
- You can also find the over all score given to a company by selecting ‘compare to current’ against your chosen tariff. This will show you the scores for the new company as well as your current supplier.
In some instances there may be no star rating displayed against a tariff. This is usually because the company is very small, so we received fewer than 30 responses to our satisfaction survey and therefore did not have enough data to produce a rating.
