Latest scores from independent consumer champion Citizen’s Advice found ScottishPower has once again ranked highest of the UK’s large energy suppliers when it comes to customer service.

As the statutory advocate for energy consumers, the charity publishes a quarterly rating of all energy suppliers with over 25,000 customers. It compares suppliers across three different categories; complaints, contact waiting time and customer commitments.

The latest results mark the sixth quarter in a row ScottishPower has topped the large suppliers for each measure.

Andrew Ward, CEO of ScottishPower’s Customer Business, said: “Our teams work tirelessly to improve and enhance our services for all our customers and I’m delighted to see their efforts reflected in this latest Citizen’s Advice research.

“Looking after our customers is at the heart of everything we do and we’re committed to providing them with the service possible; not only reducing call waiting times but giving our customers a number of ways to contact us that best suits their individual needs.

“This includes our award-winning digital app, offering a first-class user experience for both direct debit and pre-payment customers and a live chat facility from 7am to 11pm, 7 days a week.”

The study by national charity Citizen’s Advice is among the most robust and extensive on customer service provision by energy companies in the UK. Its latest round of scores covers the period Oct-Dec 2024.
