UK Power Networks has been ranked among the UK’s top 10 organisations for customer service and named the highest-performing utility in the latest UK Customer Satisfaction Index (UKCSI).
The company, which delivers electricity to 8.5 million homes and businesses across London, the East and South East, ranked 10th across all sectors and was the only utility to feature in the top 50.
It marks the eighth time UK Power Networks has topped the utilities sector in the UKCSI, published twice a year by the Institute of Customer Service.
UK Power Networks achieved a score of 84.4 out of 100, compared with the UK-wide average of 78.3 and the utilities sector average of 73.7. It was also one of only two organisations in the top 10 to improve its score by more than 3.5 points year-on-year.
The index measures performance across customer experience, complaint handling, customer ethos, emotional connection and ethics.
UK Power Networks ranked in the top 10 for both ethics and complaint handling, with the Institute highlighting trust and support for vulnerable customers as key differentiators among the UK’s highest-performing organisations.
Jo Causon, CEO of the Institute of Customer Service, said: “Congratulations to UK Power Networks on an excellent set of results in the July 2026 UKCSI. To rank among the UK’s top 10 organisations across all sectors is a great achievement and they have seen a significant year-on-year improvement.”
