Our energy supplier table 

Here at Energy Helpline we like to make things easy for you. That’s why we’ve created a table filled with a large number of suppliers here in the UK, a little bit about them and how highly they are rated.  

Each score rating has been generated by using specific information, such as the features of each tariffs the energy suppliers have to offer and Citizen’s Advice complaints data, a great website for checking the customer service ratings of each individual company.  

We hope you can gather the information you need about particular suppliers using the table we have created below, while also using it to help you make any decisions if you’re thinking about changing your current energy supplier. The suppliers are also ordered according to their rating, so you can start from the top knowing you’re reading the most well-thought of first!
