Customer Service

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.

Information correct as of: February 2018

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 gas suppliers perform on these, alongside other customer satisfaction measures. The data comes from the GfK Energy Research Panel and covers the period between January and March 2017. From January 2017 onwards, a new methodology for the customer satisfaction survey has been used. Please see the more information tab for details.

Methodology

This data comes from the GfK Energy Research Panel. It’s a semi-continuous, nationally representative panel of 10,000 homes in Great Britain. The panel provides ongoing satisfaction and switching information. The data is not for commercial use. 

Customers were asked the question 'How satisfied are you with the service you get from your current supplier?’

In 2017 Gfk changed their methodology in a number of ways that affect the comparability of data, wave on wave. From 2017 this data comes from an online survey, whereas prior to 2017, surveys were done online and over the phone. Also, prior to 2017, the five metrics presented were asked on a 5 point satisfaction scale. Customers were asked the extent they were satisfied with each aspect, and answered either very satisfied, fairly satisfied, neither satisfied nor dissatisfied, fairly dissatisfied, very dissatisfied.

From 2017 these answer scales have changed. Overall satisfaction, ease of contact and ease of understanding bill are now asked on 7 point scales. For these metrics we now show the data for those who said extremely satisfied, very satisfied or fairly satisfied. Recommendation is now asked on a scale of 0-10. We are showing data for customers who said that their likelihood to recommend their supplier on a scale of 0-10 was 8 or above. The question on suppliers valuing customers has remained a 5 point scale and so the data presented remains the same (those who answered very satisfied or fairly satisfied).

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. Missing data points in the complaints charts are due to suppliers not making the information available in time for our publication update. We have investigated Scottish Power and npower for breaches of the Complaint Handling Standards Regulations 2008. We are currently investigating whether Extra Energy is complying with the Consumer Complaints Handling Standards Regulations 2008.

This chart shows the average number of weeks customers are expected to take to repay their debt if they had a domestic gas PPM installed to repay debt between January 2017 and December 2017 (Q1 - Q4 2017).  The average number of weeks that customers were given to repay their debt ranged from 9 to 308 weeks.

Note: Only suppliers who had PPM customers repaying a debt during at least one of the four quarters are shown on the graph. For each supplier shown on the graph, we have calculated a weighted average of the last four quarters based on the total number of new PPMs installed for debt for each supplier in the four quarters.

Relevance and further information

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. Suppliers are expected to set a level of debt repayment that is affordable for the customer, this can mean customers with high level of debts will be making repayments for a considerable period of time.

This data covers the period Q1 - Q4 2017. This is the latest 12 month period for which we have data available.

At-a-glance summary

This chart shows the average weekly debt repayment rates for customers who had a domestic gas PPM installed to repay debt between January 2017 and December 2017 (Q1 - Q4 2017). The average weekly debt repayment rate ranged between £3.08 per week and £14.26 per week, with the majority being between £4 and £7.

Note: Only suppliers who had PPM customers repaying a debt during at least one of the four quarters are shown on the graph. For each supplier shown on the graph, we have calculated a weighted average of the last four quarters based on the total number of new PPM installed for debt for each supplier in the four quarters.

Relevance and further information

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.
