nPower Energy Reviews  

Unfortunately, nPower does not have a positive online reputation, with only a 1-star rating on Trustpilot that is from over 1,400 reviews. Only 3% of those reviews are positive, while a massive 92% fall within the negative category and the rest are somewhere in the middle.

Many of the negative reviews state that nPower are challenging to get into contact with, problems regarding overbilling and their complaints department don’t get back to customers.

Although online reviews aren’t always accurate, it is an idea to take them into consideration when deciding whether to switch suppliers.

Positive nPower Reviews

David Childs on Trustpilot:

Most of what we need is accessible online and, on the couple of occasions I have had an issue or query, the customer support team are responsive and very helpful.

Negative nPower Reviews

G. Green on Trustpilot:

Trying to contact this dreadful company for over three days now. You cannot call as you are put on hold and told they are too busy every single time ever, trying to arrange a call back is just as bad been waiting for over three days for that. Managed to get onto their live chat and as soon as I told them I wanted to end my tariff they informed me they were not getting my responses and ended the chat!
