NPower Customer Services

0800 316 9331

Npower are one of the UK’s largest energy and utility suppliers. As one of the Big Six, they control a significant portion of the energy market and as a result they have a vast customer service network made up of UK call centres and overseas call centres. Recent surveys conducted by consumer group Which? rank Npower’s customer service as one of the worst in the country, with the top five spots dominated by independent energy suppliers. Regardless, the lure of Npower remains strong, thanks to their competitive energy prices and tariffs.

Because they are one of the leading energy suppliers in the UK, their customer service department can be inundated with phone calls. The phone number we list here is a direct dial number with an automated system at the other end. Simply choose the options relevant to your enquiry, and you will be connected with the correct department. If you choose the wrong option by mistake, all is not lost. Your customer service advisor should still be able to help you, or they will redirect you to the correct department.
