What’s Npower Business Solutions’ renewable energy generation like?

Npower Business Solutions has received triple certification to the Carbon Trust Standard for its work to reduce carbon emissions and improve waste management across all of its offices throughout the United Kingdom, and remains the only energy company to have received this accolade

All of the paper npower uses to communicate with its customers comes from 100% sustainable sources. These forests are meticulously managed to reduce the pressure on natural forests providing similar resources, while also able to provide many other environmental benefits alongside their primary function.  

When it comes to tariffs and renewable electricity, however, it is unclear whether or not npower offers 100% renewable electricity with its tariffs. 

100% renewable electricity is almost an industry-standard inclusion within energy tariffs these days, so maybe they’re not mentioning it because it’s a given, but nothing is clear on their website. 

However, they are owned by E.ON as we have mentioned, and E.ON includes 100% renewable electricity as standard with all of their energy tariffs, which is derived from renewable generation assets, UK wind generator supply agreements and the purchase of renewable electricity certificates. With this in mind, it would seem unlikely npower’s tariffs weren’t powered using the same energy.

E.ON offers three types of boilers; combination, regular and system boilers. 

Boiler cover via HomeServe

Solar power

E.ON offers solar panel installation, which costs £121 a month with their interest-free finance option over 36 months. 

With E.ON’s solar panels you’ll become eligible for the Home Exclusive energy tariff should you want the option in the future. If this is something that appeals to you in the future, once you’ve had the panels installed you could switch to E.ON’s Smart Export Guarantee (SEG) tariff that’ll pay you for the energy you put back into the grid. 

Npower and additional support

Warm Home Discount 

npower offers the Warm Home Discount, a government-led scheme that offers £140 to those who are eligible to help cover the costs of their energy bills during the colder months when bills tend to be at their highest. 

Our guide on the Warm Home Discount scheme should provide all the information you need to know about it. 

Npower’s customer service

npower's customer service

Npower’s Help and support tab offers to take you to a range of pages to help with various questions and issues you might want answered, such as what to do if you’re moving home and you’re worried about what happens to your energy tariff. 

There are also various pieces of content to help you with different types of energy meters found in homes, along with some information on how npower functions as an energy supplier belonging to the E.ON group. 

You’ll find a section with common questions about bills and payments that you can read if you have any issues that need solving, but of course you can always phone them in your query isn’t resolved through their online resources. 

What is Npower's contact number?

npower has two customer numbers you can call them on:

0800 073 3000


0330 100 3000

(lines open between 9am and 5pm Monday to Friday)

A live chat option is also available which will allow you to talk to someone via instant messaging on the npower website. 

Npower’s customer ratings

Npower’s Trustpilot scores aren’t good, scoring a measly 1.2 out of 5 stars. 93% of all the people to have reviewed them on Trustpilot have come out as “bad,” which is the equivalent of a 1 out of 5 review. 

A lot of the reviews have involved extremely poor experiences when talking to their customer advisors over the phone, with many going as far to say they have come off the phone feeling patronised and frustrated. Some have also stated how expensive their energy bills have been since moving to npower, advising everyone reading the Trustpilot reviews to stay well away.
