Which?: British Gas ranked worst for customer service, new survey found - how other energy firms ranked

British Gas has been ranked the worst in customer service, a new survey by Which? has found. The consumer watchdog said while the giant energy firm came in last, there was little to separate the remaining firms with the lowest customer scores, including Scottish Power, Boost, Ovo Energy, Shell Energy, EDF Energy, and E.ON Next.

The consumer watchdog received feedback from more than 9,000 energy customers in October for its annual customer satisfaction survey and also assessed 18 energy firms’ behind-the-scenes practices and policies to compile an overall score. At the other end of the scale, Octopus Energy, Ecotricity and E (Gas & Electricity) achieved the highest customer scores, with Octopus Energy receiving an overall score of 73% and was the only firm to achieve a five-star rating for overall customer service.

Meanwhile, Ecotricity and E (Gas & Electricity) scored 72% and 71% respectively, and also received four stars for their overall customer service and quality of communications about energy costs. The findings come as households suffer a price cap of £1,928 a year for the typical household, with prices predicted to remain above pre-2021 levels until the end of the decade.

While fixed deals have been slowly returning to the market, Which? said it had seen few that were significantly cheaper than the price cap, meaning the quality of a firm’s customer service was the major factor in differentiating providers.

British Gas, Boost, Scottish Power, Ovo Energy, Shell Energy, EDF Energy, E.ON Next and British Gas all received customer scores of less than 60%. However, Which? named British Gas the worst performer overall after factoring in its assessment of its customer service practices, followed jointly by Boost – part of Ovo – and So Energy.

British Gas, which supplies more than a fifth of households in Great Britain, received an overall score of 56% and scored just two stars for most categories, including accessibility – or whether a customer can engage with it effectively, value for money and accuracy of energy payments. It received three stars – an average score – for customer service overall and just over half marks for customer service and just one point out of 10 for performance against its smart meter targets.

It also received four out of 10 for how it handled complaints, losing points primarily for the volume of customer complaints it received per 100,000 customer accounts in the first half of 2023 in comparison to other suppliers. Overall, a quarter of people Which? surveyed who had engaged with their energy firm in the last year to get help with a problem said the company had made it difficult.

Which? director of policy and advocacy Rocio Concha said: “With energy prices still punishingly high and limited chances for consumers to save money by switching suppliers, good customer service is more important than ever. While Octopus Energy, Ecotricity and E were all named Which? Recommended Providers and scored highly for their customer service, others fell short of customers’ expectations.

“Which? is calling for any providers who are falling short on customer service to up their game and ensure customers are able to contact them easily and get the answers they need.”

An Ofgem spokesperson said: “It is more important than ever that energy suppliers are there for their customers which is why we recently introduced a robust set of additional rules to drive up standards of customer service in crucial areas such as call waiting times and proactive outreach and support for customers who are struggling with debt. Suppliers must remember that customers who receive poor service can and will vote with their feet and take their business elsewhere.

“Over the past 12 months we have seen a rise in switching as competition slowly returns to the market. People should weigh up all the information, seek independent advice from trusted sources and consider what is most important for them – whether that’s the lowest price, the security of a fixed deal or a higher standard of customer service.”

A British Gas spokesperson said: “This survey is behind the curve and is based on data that is up to a year old. Since that period, we’ve targeted more than £25 million of investment on improving service and customers are seeing a difference – this includes hiring 700 new contact centre agents and extending our opening times. We continue to be focused on customer service and helping our most vulnerable customers through our sector leading £100 million customer support package.’’
