Which? reveals the appalling call waiting times faced by energy customers

A Which? investigation has revealed the worst energy firms for leaving customers hanging on the phone – with some subjecting callers to an average wait of almost half an hour.

The consumer champion made more than 450 phone calls in total to 38 gas and electricity suppliers and also tested live chat and email services – finding huge variations in how long customers were kept waiting to speak to a member of staff.

Spark Energy, which went bust last week, was the worst firm for call waiting times during Which?’s investigation, leaving customers stuck on hold for 27 minutes 21 seconds on average – a call length that would potentially cost someone using a mobile £15.

Utilita left its customers waiting for an average of 24 minutes 19 seconds and had the longest single call waiting time of a shocking 72 minutes 40 seconds – the same amount of time it takes to get the train from London to Southampton, where the firm’s head office is.

Five of the Big Six energy firms kept customers waiting for around 10 minutes or longer on average – with Npower the worst of the bunch on 20 minutes 31 seconds.

Scottish Power was the best of the Big Six with an average call waiting time of three minutes 29 seconds, while smaller suppliers Affect Energy (10 seconds) and So Energy (21 seconds) were the best performers overall.

Npower was by far the worst supplier for live chat response times – taking more than 17 minutes on average before a customer service adviser responded.

It was followed by SSE and Eon, which both took more than four minutes on average – although Eon customers might consider themselves lucky to get a response at all, as our researchers found live chat was unavailable on 10 out of 12 attempts.

Spark Energy customers frustrated with dire phone waiting times for customer service would have been more impressed with an average waiting time of 25 seconds on live chat – although the service was unavailable on six out of 12 attempts. It’s a similar story for Utilita which answered live chat enquiries in 93 seconds on average but was unavailable on seven out of 12 occasions.

Those firms which didn’t offer live chat, we contacted  by email or online form instead. Both Engie and Economy Energy failed to answer any of our 12 enquiries within two weeks.

Eight firms – Solarplicity, Octopus Energy, The Co-Operative Energy, Affect Energy, Sainsbury’s Energy, Flow Energy, So Energy and Tonik Energy – responded to emails or online forms within a day, on average.

A Which? survey of 8,000 UK energy customers in September and October 2018 found phone is still the most popular way to contact suppliers.

Three in 10 (30%) people said they had phoned their energy company in the past year, while one in seven (14%) had emailed and one in 10 (10%) had used live chat.

Energy companies shouldn’t use the forthcoming energy price cap as an excuse to become complacent on customer service. Which? is calling on the Government and regulator to keep up the pressure on energy companies to improve their offering to consumers.

Alex Neill, Which? Managing Director of Home Products and Services, said:

“As if regular price hikes aren’t bad enough, customers of some energy companies are facing infuriating waits just to get through to a customer service adviser on the phone.

“’No one should have to put up with shoddy customer service and rip-off deals. If your current supplier is constantly leaving you in the lurch, you should switch and potentially save almost £400 a year.”
