Data portal

Energy suppliers offer more than different prices – they also offer different levels of customer service. These indicators give a snapshot of the performance trends we monitor on supplier customer service. 

Our indicators are accessible as interactive charts which we will update regularly throughout the year. You can refine and expand chart views as well as download data and graphics based on your selections.

If you have feedback on the indicators, please contact us.

Select from the below to view the indicators and for an overview of our monitoring themes.

Service quality

We all expect certain things from our energy suppliers, like understandable bills and being able to contact them when we need to.  These indicators compare how suppliers perform on those and other fundamental points.

We expect certain things from our energy suppliers, like being able to contact them when we need to and clear utility bills we can understand. You can use this chart to compare how the six large electricity suppliers perform on these, alongside other customer satisfaction measures. The data comes from the GfK Energy Research Panel and covers the period between October and December 2016.

If things go wrong

No-one wants to have to complain about their energy supplier, and if you do, you want them to resolve your problem as soon as possible. Ofgem, Citizens Advice and the Ombudsman publish complaints statistics. The separate statistics show how many complaints suppliers receive, how many Citizens Advice handle, weighted by the seriousness of the complaint, and how many are accepted by the Ombudsman after failing to be resolved by the supplier. This helps to show a full picture of the customer’s complaint from start to finish. 

The complaints data has been provided by each supplier. We have investigated Scottish Power and npower for breaches of the Complaint Handling Standards Regulations 2008.

During 2015, five suppliers disconnected domestic gas customers due to debt (49 disconnections in total). Utility Warehouse disconnected the largest number of customers, with 20 customers disconnected. It was also the worst performer relative to the number of customers – this was equivalent to disconnecting 47 customers if it had 1 million customers. Only suppliers that disconnected customers for debt during 2015 are shown.

The number of customers disconnected at each supplier during 2015 was:

  • Utility Warehouse - 20
  • npower - 19
  • SSE - 7
  • Ecotricity - 2
  • Ovo Energy - 1

Relevance and further information

Suppliers must only use disconnection as a last resort. They must not disconnect customers in debt unless they have offered a range of repayment options and have exhausted all available means to recover a debt.

Suppliers must offer the customer an option to pay for their electricity and gas through a PPM to recover debt where it is safe and reasonably practicable in all circumstances for the customer to do so.
